If it's hard for you to communicate with your parents, don't worry about it. Here are some advice for you to bridge the generation gap （代沟）.Don't argue （争辩） with your parents. Don't get to your parents when you are angry. Your parents probably won't consider your ideas if you are shouting at them. And you can't express yourself well if you are angry.

If you don't think you can speak to them at the moment, try writing a letter.Try to reach a compromise （和解）. Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael's mother didn't agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise.

In these situations, it is especially important to show love and respect （尊敬） to them. Showing respect will keep your relationship strong.Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why.

It is twice as tall ascommon rice,which is usually about one meter tall. People called it a “dream coming true"moment or Yuan Longping, who was the top rice scientist in the world and was regarded as the “father of hybrid rice". This special type of rice was grown in Chongqing for15 mu. It was planted in May and harvested(收割) four months later. Each mu of the fields produced about750-900 kilograms.This type of rice is not only strong and tall, but also resistant(有抵抗力的) to flood. It can also bringmany nutrients(营养) to the plants nearby and provide a good living environment for animals in water. When the water in the rice fields is 60 -80 centimeters deep, it can even be used to raise fishes. From next year,the“giant rice"will be planted in thousands of mu of fields in Chongqing.Yuan Longping once said that he hoped to sit under the ears of rice to enjoy the cool one day.He developed the first high-producing hybrid rice.But sadly,he passed away at 91in Changsha in May 2021.

2020-2021中考英语试卷英语阅读理解题分类汇编(含答案)一、英语阅读理解专项练习试卷1．阅读理解Earlier this year, China achieved a new milestone (里程碑) in space research. On January 3, 2019, Chang'e-4 became the first lunar probe (月球探测器) in history to successfully land on the far side of the moon.The Earth's gravity (重力) slows the moon's rotation (自转), matching it to the speed of its orbit (公转). Therefore, the far side of the moon is almost "dark" and has never been seen. It's this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space research. Being blown by solar (太阳的) winds, the far side may have the special minerals (矿物质). For this reason, Chang'e-4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft. Chang'e-4 is also carrying flower seeds, potatoes and silkworm eggs to see whether life is possible on the moon. If it is, then the moon will become a possible choice for space travel in the future.However, research of the "dark" side isn't easy. As the far side is blocked(阻断) off from us, radio noise coming off Earth is also blocked. This is why China's relay satellite (中继卫星) Queqiao was sent up in May, 2018. Thanks to Queqiao, the communication problem between Earth and Chang'e-4 has been well solved.Power supply (电源供应) is also a challenge to the task. Chang'e-4 gets energy from the sun through its solar panels. As we know, a lunar day has the length (长度) of 28 Earth days. After Chang'e-4 was sent up on December 8, 2018, it took the probe over 20 days to orbit the moon to be in a position to be able to land in moon daylight and use its solar panels.Luckily, everything goes well, Chang'e-4 has worked on the "dark" side for over 5 months. It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments.The New York Times used the word "groundbreaking" to praise the task and wrote that "it will offer help to the history and development of the moon".（1）When was Chang'e-4 sent up?A. In May, 2018.B. On December 8, 2018.C. On January 3, 2019.D. The passage doesn't tell us.（2）The main tasks of Chang'e-4 don't include _______________________.A. studying if life is possible on the moonB. studying the effect of solar winds on the lunar surfaceC. solving the communication problem between Earth and other probesD. researching any mineral found by the spacecraft（3）The meaning of the underlined word "groundbreaking" in the last paragraph is the closest to "________________".A. harmfulB. unpredictableC. riskyD. pioneering（4）According to the passage, which of the following statements is NOT true?A. Chang'e-4 has sent back many photos of the far side of the moon.B. A lunar day has the length of 28 Earth days.C. China's relay satellite Queqiao was sent up in order to offer power supply to probes.D. Chang'e-4 is the first lunar probe in history that has successfully landed on the "dark" side of the moon.【答案】（1）B（2）C（3）D（4）C【解析】【分析】文章大意：文章介绍了中国的嫦娥四号月球探测器，为我们讲述了嫦娥四号升空时间，什么时候在月球背面着陆，如何跟地球进行通讯联系等等。

根据短文内容，从每题所给的A、B、C、D四个选项中选出最佳答案。
AArtificial intelligence(AI，人工智能)can help us make phone calls. It can guide us to where we wantto go. It can play games. And now，AI can do even more things.Researchers from Microsoft have created the first machine translation system that can translate news articles from Chinese to English.The researchers tested the system by asking it to translate hundreds of sentences taken from newsstories. Then，language experts compared the results to the translation that were done by humans. Theexperts said that the system's translations were as good as the human translations.Experts used several methods to improve the system's translation abilities. “Much of our researchis really learned from how we humans do things，” lead researcher Liu Tieyan said.One method is called dual learning(对偶学习). In this method，the system translates every sentencefrom Chinese to English，as well as translates the sentences back from English into Chinese. This way，the system can improve itself and learn from its own mistakes. This is similar to what humans do to makesure their translations are exact.Another method makes use of deliberation networks(推敲网络)．The researchers taught the system torepeat the process of translating the same sentence over and over. Gradually，the system can improve the quality of its translations. This is similar to how people correct their own writing by going throughit again and again.( )1. Microsoft created a system that can ________.A. make phone callsB. give people directionsC. play games with peopleD. translate news articles( )2. What did the experts say about the system's translations?A. They were not exact.B. They were as good as human translations.C. They were better than human translations.D. It's hard to tell whether the translations were correct.( )3. Dual learning trains the system to translate ________.A. more quicklyB. different sentencesC. more exactlyD. the same sentence repeatedly( )4.

Let’s have a look at these teenage inventions that might change the world.Banana leaves usually go bad in two or three days. Tenth Hadith, a teenager from India, used UV to make the leaves stay fresh for a year. Tenth thinks that one day the leaves will be used for making plates,cups and other things.David Cohen, an American teenager, built an earthworm(蚯蚓) robot. It is able to go into the smallestplaces, where humans or dogs can’t go. It will be used for finding people in a fire or an earthquake.Remya Jose, a 14-year-old from India, found it tiring and boring to hand wash clothes in the nearbyriver. She reused some bicycle parts and created a washing machine that saves time, energy and keepspeople fit at the same time.Kenneth Shinozuku, a 15-year-old from New Y ork, noticed that his grandfather who got Alzheimer＇s disease （老年痴呆） would often leave home and get lost. So he invented the wearable sensors(感应器)to help people find their family members like his grandfather.( )1. What is the passage mainly about?A. Popular adsB. Useful machinesC. Strange pictures.D. Teenage inventions( )2. The earthworm robot by David Cohen can ______.A. make things stay freshB. help people wash clothesC. go into the smallest placesD. take care of the old people( )3. Which of the following is TRUEA. Plates and cups are made of fresh banana leaves.B. Remya's washing machine can also keep people fit.C. David Cohen is a middle school student from India.D. Kenneth's wearable sensors will keep old people at home.CTechnology is everywhere. We see it any place we go and， in fact， almost all of us carry some pieceoftechnology with us every time we leave the house. What I always forget， though， is just how useful and powerful technology can be when we want to help othersThere is not a single room in my house that does not have some electronic devices（设备） lying around init. Whenever I am at home， I am a lmost always using at least one electronic device. If you walked into my living room on any given day， you would find that， first， I have the television on. At the sametime， I usually have my laptop resting on my knee， or I will be using my mobile phone， Even when i＇m not at home I am always using my phone， and at work or in cafes， I sit down and connect to the local wireless network on myopic.I must say that I waste a lot of time on the computer and the time I spend on it could be much betterspent if I were to take up a little online volunteeringThe technology we carry about everywhere can have a great power to do good for the world and to help others and recently I discovered just how much online volunteering there is to do in the world. From using yourlanguage skills to do translations， to developing and managing projects and helping with IT work， there is so much that so many people can do to help people in their own countries and across the world. TheUnited Nations， in fact， has a huge page with ＂Volunteers Recruited＂ on its website.This work can support the poor and help charities who cannot pay for staff. Many o rganizations only require you to work an hour a week-some even less. And the support provided by online volunteers can really helpmake a difference to those in need.( )1.

In the writers opinion， people should spend more time with technology.A. working on computer programsB. keeping the Internet safeC. inventing electronic productsD. helping people in need( )4. What can be the best title for the passage？A. Website DesignB. Internet OrganizationsC. Online VolunteeringD. Online TranslationDDo you find it difficult to put down your mobile phone?If yes，you're not alone. These days，many people are facing the stress in the use of mobile phones. They reach for their mobile phones when they wake up in the morning，and keep checking their social media apps to get the latest updates(更新)．A report from Google shows that 70 percent of people don't want to spend much time on their phones.This is why Google introduced an app called Dashboard for the new Android operating system(安卓操作系统). This new app includes functions(功能) that help users manage the time. For example，users can see how many times they've unlocked their phone，how many times they've checked their social media apps，and how much time they spend on each app every day.Once the users see this information，they'll be able to make some changes. With the App Timer(计时) function，users can set a time limit for how long they can use each app for every day. After they'vehit the limit，they won't be able to use the app until the next day. And with another function，the app gets incoming calls silent when the user puts the phone face down.If people truly want to make full use of their free time instead of losing hours on their phones，these new functions are just one way of doing that.After all，who needs to use an app to stop you from using other apps? The easiest answer would bejust to use your willpower.( )1. Where does the users' stress come from?A. Too many updates of the apps.B. Too many functions of the apps.C.

Scientists say that more than40 percent of teenagers and adults consider themselves shy. Shyness is feeling a little nervous or asif you want to hide when you're around other people or in a new situation.___ Scientists say such things as genetics（遗传基因）， life experiences， and environment can influence whether a person is shy. For example, in some families, everybody seems to be shy.What happens if you are shy? Well, being shy may cause you to avoid or miss opportunities you would enjoy. How do people overcome (克服)shyness? This is what Gilbert tells us. "When I started off trying to getover being shy, I decided to do little steps at a time, including practicing smiling and saying hi topeople. And it worked for me. “But shyness is not the kind of thing that most people can get over overnight. Overcoming shyness taketime and needs practice.Here are some tips given by scientists.Think of what to talk about before you leave home. Prepare things to talk about before you're in a social situation. For example, if you know your classmates are interested in an upcoming event, learn about itso you can join in the conversations.Let people know you're shy. If you're shy, just show it. Instead of letting people guess, tell them thetruth. Explain that you are shy and feel nervous but enjoy talking to people.Make things easy f or the other person. Remember, you’re not the only shy person around. Do what you think might help others feel good-for example, say hello or smile.Pick one social skill to practice at a time. Start simply.

Don’t let others know that you are shy.B. Wait for others to say hello to you first.C. Choose several skills to practice at a time.D. Get ready before you join in a social situation.FPossible Earth-Like Planet Next DoorScientists say they discovered an earth-like planet outside our solar system(太阳系). It is a planet that could support life.This planet is just 4.2 light years away from us. It is so close that space scientists have considered it as a next door neighbor. They say it could be reached by an unmanned spaceship before the end of thecentury—in time for people alive today to see it.An international team of scientists found the planet moving around the star called “Proxima Centauri”. The result came out last month from the scientific magazine Nature.Scientists have long thought that a planet with water is important for life. And it has to be neither too hot nor too cold. The newly-discovered planet is a little larger than earth. Scientists have namedit Proxima B. It moves around its sun，Proximal Central once every 11 days.American scientists have been using instruments for years to look for earth-like planets. In 2013，scientists' best guess was that there are about one billion(1,000 million) “earths” in space.Alan Boss is the chairman of a group for outer space research. He said that Proxima B not onlyconfirms(确认) the discovery of a planet，but also increases the number of other possible “earths” greatly.Boss said it is possible，even likely，that most stars have at least one earth-like planet，which he considers surprising.So from the early number of a billion，this new research suggests there may be as many possibleearth-like planets as there are stars in the Galaxy(银河系). That is，anywhere from 250 billion to 500 billion“earths”．This makes the possibility of living things increasingly likely. Boss said he believes human beingswill be able to show that there is life in places besides earth in his lifetime. “I am 65，” he said，“ but I expect to still be alive when it happens.”( )1. When will it be possible for an unmanned spaceship to reach Proximal B?A. In about eighty years.B. In about 4.2 years.C. In about eleven day.D. In about one billion years.( )2. In the fourth paragraph，the writer thinks that ________ is necessary for life.A. waterB. lightC. airD. wind( )3. What does t he underlined word “This” stand for in the last paragraph?A. Scientists have discovered an earth-like planet last month.B. There are far more earth-like planets than people thought.C. Proximal B is not far from earth and is just like our neighbor.D. The Galaxy will be the only place for living things to live in.( )4. What does Alan Boss mean by saying “but I expect to still be alive when it happens”？A. His health is in good state and he's sure he will live a long life.B. Science is developing much faster than ever in recent years.C. Scientists may soon find fact that there's life on other planets.D. America is far ahead of other countries in space research.GBeauty sleep is a real thing, researches have shown that people who have enough sleep look more attractive (有魅力的) to others.A few bad nights is enough to make a person look "especially" more ugly, their sleep experimentsshow.The researchers asked 25 university students to join in their sleep experiment. They were asked toget a good night's sleep for two nights.A week later, they were asked to sleep for only four hours every night for two nights in a row.The researchers took make-up free (素颜) photos of the volunteers after both the good and the badsleep.Next, they asked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health, and sleepiness, as well as asking them: "How much would you like to make friends with this person in the picture?"The strangers were good at judging if the person they were looking at was tired, and, if they weresleepy, their attractiveness score was low.The strangers also said they wouldn't want to socialize with the tired students. The researchers say this is natural for people. An unhealthy-looking face makes people run away. In other words, people don't want to hang around with people who might be ill.Dr. Brewer, an expert at the University of Liverpool said "Judgement of attractiveness is oftenunconscious (无意识的), hut we all do it, and we are able to judge on even something small like whethersomeone looks tired or unhealthy. This study is a good reminder of how important sleep is to us."( )1. When did the researchers take make-up free photos?A. After two nights good sleep.B. After two nights bad sleep.C. Before the experiment.D. After both two nights good sleep and two nights' had sleep.( )2. The researchers asked the strangers to do the following except _______.A. telling who looked healthierB. telling who didn't have many friendsC. telling who missed a lot of sleepD. telling who was attractive( )3. What kind of friends did the strangers like to make?A. The people who were tired.B. The people who were sleepy.C. The people who were unhealthy.D. The people who were attractive and energetic.( )4. What does the underlined word "socialize "mean in Chinese?A. 合伙B. 玩耍C. 交往D. 共事( )5. According to the passage, which of the following is the best title?A. Beauty sleep, More attractiveB. More sleep, More FriendsC. Less sleep, Fewer friendsD. No attractiveness, No friendsHImagine having a simple app(应用程序) that works like this: When you need help，just open the app，touch the “not OK” button and a text message will be sent to five preselected(预先选定的) people，along with a location(位置) to show where you are. The message reads，“Hey，I'm not OK. Please call me，text_me，or come to find me.”US teenagers Hannah Lucas,15，and her brother Charlie,13，have created an app called not OK. Peoplejust need to pay $1.99(12.5 yuan) each month to use it.Hannah was inspired(启发) to create the app during a dark time in her life last year. She sufferedfrom a disease that caused her to pass out at school. Other kids sometimes bullied(欺凌) her about this.She felt sad and wanted to find an app that would allow her to get help when she wasn't feeling OK.She asked her brother Charlie，whose nickname is “Tech Support”，to find such an app. When they couldn't find one，they decided to create one themselves.They came up with some designs for the app first. Charile took a programming class last summer andbuilt a website for the app. Hannah also shared her idea in her summer business class. Some a pp developers showed interest and decided to help her. At last，the app came out in the US and Canada on January 31.Hannah is happy that her app is help ing others. “It makes everything I went through last year worthit，” she said.( )1．Who will know you're in trouble when you touch the “not OK” button?A.

Influenced by the launch of the first manned mission to Mars next month，you will most likely get a gift card for a space trip.The interest in trips,100km above the surface of the Earth，has grown steadily since such a trip began.However，the market has grown much larger this year since the official announcement of the Mars mission. More low-cost space-lines have entered the market and you can now find flights for such a trip for aslow as $3,495. It's very reasonable.Space tourism(旅游业；观光业)is one of the markets that have developed fast during the last decade，with the opening of the Star bright Hotel on the moon a s well as the low orbital hotels that started accepting guests. However，accommodation in space is still expensive for the average household，so the suborbital(亚轨道的) flights with thirty-minute weightlessness during the three-hour flight will for some time be the most popular trip.However，the space-lines might in the future face fierce competition between space elevators(太空升降舱)，like the one that is projected to start construction within two years. Once i t is fully functional，it will start to ship cargo to space. But it will accept passengers as soon as possible to get back thelarge investment. Even if the elevator becomes successful，it will take several years before there aremore elevators in the world to get in the competition for space traffic with the space-lines.Those who are looking for a little bit of adventure and have extra money to spend may want to consider a suborbital flight in space. While a suborbital flight may not be the space mission that you have always dreamed of，it will give you the rare opportunity to see what our planet looks like in a high-altitudeflight outside our atmosphere. So before you enjoy a trip by elevator to space，enjoy a suborbital flight first.( )1. From Paragraph 1，what will happen in January,2031?A. A gift card will be taken to Mars.B. Mars will be explored for the first time.C. Man will go to Mars for the first time.D. An affordable space trip will come true.( ) 2. The underlined “average” can most probably be replaced by “________” in this passage.A. commonB. high-incomeC. low-costD. low-income( )3. What is the space elevator's purpose in accepting passengers as soon as possible?A. To ship cargo to space.B. To get in the competition between space-lines.C. To start the construction of more space elevators.D. To get back the large investment.( )4. Which of the following is NOT TRUE according to the passage?A. Space tourism has developed fast during the last ten years.B. A suborbital fight may be the space mission that you have dreamed of.C. The suborbital flights will be the most popular trip for some time.D. Even though the elevator becomes successful，we still wait for a few years to see more elevatorscome out.( )5. We can know from the passage that________.A. the low orbital hotels have opened since a space trip beganB. within two years，space elevators will begin to ship cargo and people to spaceC. during the suborbital fights，you will experience 30 minutes weightlessnessD. if you want to meet your curiosity，you may try a suborbital fightKThere's much to see under the sea，but you need to remember that light behaves differently in waterthan in air. The objects appear closer to you than they exactly are. You might find yourself reachingout of to touch something and completely missing it.Objects under water will appear larger than they would on the surface，too. Be careful not to tellany stories about the big fish that got away. That fish might not be so big after all! It's just becausesometimes things can seem to be as much as about 33 percent bigger in water!What's more，in deeper water，colors just don't seem as bright. In fact，it looks as if some colorsare missing. Remember the color of an object results from the wavelengths(波长) of light that are reflected (反射) from its surface. And light is taken in as it moves down through the water.Swimmers wear wet suits to keep warm underwater. Let's take a bright red，yellow，and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths，the longest among these three colors，are missing. As you go down deeper，the same thing will happen tothe yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater，you will look terrible，like a ghost(鬼怪)! And you have to wait for your return to the surface to enjoythe bright colors again.( )1. You miss the object under water when you want to touch it because ________.A. your eyesight is quite poorB. you are not quick enoughC. it is not as close as it seemsD. it disappears very quickly( )2. The example of the wet suit is used to explain the change of ________ of an object underwater.A. the sizeB. the colorC. the positionD. the weight( ) 3. The underlined word “descend” probably means “________” in Chinese in this p assage.A. 上升B. 酒污C. 屏息D. 下潜( )4. Which of the following is true?A. A four-meter-long fish looks three meters long underwater.B. The wavelengths of red light are longer than those of blue light.C. Much water will be taken in by the swimmer deep in the wave.D. You will see a ghost if you go as deep as 6 to 9 meters into the sea.( )5. The best title of this passage is ________.A. The Standard of Color UnderwaterB. The Direction of Light UnderwaterC. The Brightness of Color UnderwaterD. The Behavior of Light UnderwaterLArtificial intelligence(人工智能)，or AI in short，is the science of giving computers and machinesability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.AI is rapidly catching up with the human ability to read faces. As a result，facial recognition(识别) is used a lot in the world. Chinese police use this technology to identify criminals(罪犯). Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing(网约车) drivers and lets people pay for things with a smile.AI is also used in self-driving cars，which are believed to be the future of driving. Most driversmay wave or nod at passers-by to let them cross the street，but self-driving cars don't have this abi lity. Carmakers are testing a light signal system to help them “speak” to humans. The system can show whatself-driving cars will do. For example，if a driverless car is yielding(让路)，it will flash two whitelights side to side. A rapidly flashing light tell s passers-by that the car is about to speed up.Service Robots also show you how powerful AI is. Imagine this—you come back from school and your robot housekeeper is waiting for you at the door. After dinner，he teaches you to play the piano，just like a real music teacher. Such thoughts will soon happen in the real world. In the future，more and more service robots will become good home helpers.AI is so powerful that it can help human beings and even replace us in many jobs.( )1. What does the underlined word “identify” in Paragraph 2 probably mean?A. To let somebody know his mistakes.B. To come to realize and tell who is who.C. To take somebody to the police station.D. To inform somebody of something important.( )2. According to the passage，what is facial recognition used for?A. Driving cars.B. Making people smile.C. Calling the police.D. Checking people's information.( )3. Which technology has been used in real life according to the passage?。

birthday gifts．And it's a two﹣way street．People who have pets tend to have lower blood pressure．They also have a lower heart ﹣disease risk．Scientists are finding more and more evidence that animals can also help improve mental health．Some clinics have been using "pet therapy"（宠物疗法）alongside traditional medicine．Here is a look at some of the cures．RabbitsIn one study，scientists told a group of stressed﹣out adults to pat a rabbit and a rabbit toy．The toy had no effect．Touching the living rabbit，however，reduced anxiety（焦虑）．Crickets（蟋蟀）Animals don't have to be soft and lovely to help．In a 2016 study，elderly people who were given five crickets in a cage felt happier after eight weeks．The act of caring of an animal seemed to make the difference．HorsesHorses are among the most﹣studied therapy animals．In Europe，they have been involved in medical treatment plans since the 1860s．Activities like brushing the fur of a horsehave been shown to reduce anxiety in people of all ages．FishOne of the study focused on people who had Alzheimer's disease（阿尔茨海默氏病）．When they dined in front of a tank of colorful fish，they ate more．DogsChildren who struggle with reading are less anxious when they read aloud to a trained dog．Their attitudes change and their skills improve．（1）About of pet owners in America buy their pets birthday gifts．A．one﹣thirdB.50 percentC.95 percentD．three quarters（2）The

remembering its name，its shape，its color or its size？Are you remembering what it is used for，or the sound it makes when the teacher writes on the blackboard？Scientists say that memory includes different parts of the brain，such as language and the ability of sense．They believe that you begin to create a memory when you notice something with your senses．Then，messages are sent to different brain cells，which join together to form connections．A new connection goes into your short﹣term memory．It is stored there for about 30 seconds，and then it is either lost or stored in your long﹣term memory．Having a good memory means making lots of connections and storing them in your long ﹣term memory．To do this，you need to keep your brain in good shape．Eat plenty of brain food such as fish oil，fruit and vegetables．Laughter also makes your brain more active．Also，don't forget to exercise．So do some sports or just move around a lot in the house．Finally，get plenty of sleep．This will make your memories grow stronger．When you want to remember new information，you must pay special attention．Use your senses﹣sight，smell，hearing and touch﹣and keep repeating the information．To do well in your exams this year，turn off the TV，silence your mobile，and review your work regularly．To remember something special，use your imagination to create visual（视觉的）connections．For example，you need to take a pencil，an eraser，your ID card and chips to your next exam．Imagine the ID card as the body of an animal，the pencil its long neck，and the eraser its head．Your animal is hungry，so now imagine it eating a bag of chips．It may sound crazy，but it's fun and it works．Another way is to do something different to yourroom．Turn a picture upside﹣down，or tie a sock around the door handle to remind（提醒）yourself of something to remember!（1）At the beginning，the writer gives an example to．A．lead in the topic of the articleB．show the importance of chalkC．let readers remember the wordD．make readers know his

apps．Thirty﹣one percent of teens get in touch with friends they have not met in person，and thirty﹣two percent have communicated with a complete stranger online．An officer named Pamela Casey in the US is helping children know more about smartphone dangers．Casey joined "CBS This Morning" to discuss the risks and how parents can protect their kids by changing the settings （设置）on their phones．Casey's interest in the subject began with a phone call from one of her friends whosedaughter had been taking inappropriate （不适当的）photos．"She said she found them in a vault app．The app is like a calculator （计算器）but you put in a certain pass code．It took you to a vault that she had hidden all these photos that she had been sharing，" Casey said．The mother told Casey，"You've got to tell everybody．"（1）How many American teenagers have their own smartphones？A．About 25%．B．About 30%．C．About 35%．D．About 75%．（2）Why did Pamela Casey join "CBS This Morning"？A．To discuss the risks and protect kids．B．To help

called vault．（4）What's the meaning of the underlined phrase "pass code"？A．地址B．密码C．通行证D．身份证9．3D printing is becoming more and more popular．We are now able to print things such as clothing，musical instruments and even cars．People and businesses are able to create the things they need very quickly and easily by using 3D printers．But can you imagine printing food？Some scientists are trying to change the diningexperience completely by doing this．They hope that having a 3D printer in the kitchen will become as common as the blender or microwave．Scientists say that they are easy to use：you simply have to choose a recipe（食谱）and put the uncooked food "inks" into the printer to make the food you want．This means that it would be very quick and easy to create tasty and healthy meals．Using 3D printers to create your meals would also be saving the environment．There would be less need for traditional growing，shipping and packaging steps as food production would be a lot quicker and better．For example，tree leaves and insects could be turned into tasty products! Printing food could also help people who have a swallowing（吞咽）trouble．They could program the printer to print softer kinds of their favorite foods so that they would not have difficulty swallowing them．However，some people think that a future of 3D﹣printed food would be a disaster．It could take away many jobs，including those for growing，shipping and packaging food．Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked "food ink"．Traditional cafes and restaurants might lose business，too．Also，there are worries about the healthy value of printed food：is it really possible to get what we need from food﹣based "inks" or something like that？As we know，cooking and eating together with family and friends has long been a traditional and enjoyable activity．It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button．（1）The second paragraph mainly tells us．A．we can change our recipes by 3D food printingB．there are many ways of printing food on the 3D printerC.3D food printing has become very common in the kitchenD．some scientists are trying to make 3D food printing used widely（2）The writer gives the example in Paragraph 3 in order to．A．show us how 3D food printing worksB．tell us why we should use 3D food printingC．help us to know what we can use to print foodD．let us understand when to use 3D food printing（3）How many disadvantages of 3D food printing are mentioned from the last two paragraphs？A．Two．B．Three．C．Four．D．Five．（4）What is the writer's opinion about 3D food printing？A.3D﹣printed food is tasty and necessary．B．It is difficult to understand 3D food printing．C．Cooking food is more pleasant than printing food．D．It is happy to see the change of the dining experience．10．Every 14 days，another language dies．There are many reasons for this．Some people think more common languages have more economic（经济的）power．Because of this，young people choose to learn a common language as they think it is more useful．Another reason is that some languages aren't written down．Guujaaw is a leader of the Haida Nation，whose people have lived on the Queen Charlotte Islands，Canada，for more than 10，000 years．Their language is endangered．Traditionally，it wasn't written down，and，as a result，some people are worried that it will die one day．Guujaaw replies to this，"We talk to each other，listen，visit，and believe in the spoken word．Expressing yourself without writing is natural．" However，if Guujaaw's language and others like it are going to stay alive，writing may have to become part of their lives．When a language dies，a lot of knowledge dies with it．To begin with，language is a huge part of the culture of the people who speak it．Language allows speakers to say certain things：words that describe a cultural idea may not translate exactly into another language．Furthermore，many endangered languages have rich spoken cultures．Stories，songs and histories are passed on from older people to younger generations（一代）．Elizabeth Lindsey，a language researcher，emphasizes（强调）this．"When an elder dies，a library is burned，" she says．Also，language death affects our knowledge about nature．Local people often have a deep understanding of plants，animals，and the relationship between them．David Harrison，a researcher on endangered languages，reflects，"80% of plant and animal species（物种）have been undiscovered by science．But that doesn't mean they're unknown to humans．"Many languages are endangered．However，it's not too late．Children often grow up speaking two languages．"No one…becomes richer by giving up…one language to learn another，" Harrison said．If children feel both languages are important，they will use both．So，it is necessary that children realize how useful their local language is．（1）How many reasons are mentioned for endangered languages in Paragraph 1？A．2B．3C．．4D．5（2）What does the writer mainly tell us in Paragraph 2？A．How cultures are passed on．B．How cultures are discovered．C．Why languages are written down．D．Why languages are important to cultures．（3）The underlined word "affects" in the passage means ""．A．waits forB．depends onC．is different fromD．has an influence on（4）Which of the following is the writer's opinion？A．People need to use common languages more often．B．The spoken word is more important than the written word．C．Children are the hope to stop the local language from dying．D．Many animals and plants are in danger because of dying languages．11．Are You Right Handed or Left Handed？Which hand do you use when writing？About 8 to 15 percent of people are left handed．They often have to use tools that are designed for right﹣handed people．So it is difficult for left﹣handers to use most tools．If you are right handed，try this experiment：Take a knife with your left hand and try cutting a potato into pieces．Don't be surprised if you feel awkward（别扭的）．In the past，people thought it was strange to use the left hand．Young students looked down upon their left﹣handed classmates．Some children were even punished for using their left hand to write．But these days parents and teachers have accepted that．In almost every school in the world，left﹣handed students can use their left hand to write．What causes people to be left handed or right handed？Experts have searched long and worked hard on this．They concluded（得出结论）that left﹣handed people are left handed for the same reason that right﹣handed people are right handed．One out of every ten people just is a left﹣hander．It's simply like the color of our eyes﹣some people have brown eyes，while some others have black eyes．However，many researchers think that left﹣handers and right﹣handers are different in some aspects．Right﹣handers are more talkative and outgoing than left﹣handers．Many right﹣handed people understand spoken words better．For example，after they listen to directions to a supermarket，they can find it easily．Right﹣handers are good at organizing people，too．They are also better basketball guards．Just ask Yao Ming．Research shows that left﹣handers are creative and artistic．Many famous performers，like Jim Carrey and Paul McCartney，are left handed．Many left﹣handers learn better visually （在视觉方面）．In art，both Leonardo da Vinci and Michelangelo were left handed．In science，you find Newton and Einstein．The left﹣handed people are also really good at tennis and other single sports．If you prefer one hand，but you are still good at writing with the other，you are mixed handed．Research shows mixed﹣handers can remember everyday things better than other people．What did you eat for lunch two weeks ago？If you're mixed handed，you can probably remember．（1）If right﹣handers cut up potatoes with their left hand，they will．A．get hurtB．give up cuttingC．feel uncomfortableD．change their tools（2）What is Paragraph 2 mainly about？A．Causes of being left handed．B．Encouragement to left﹣handers．C．Punishment for using the left hand．D．Changes in opinions on left﹣handers．（3）According to the passage，right﹣handers．A．learn better visuallyB．are good organizersC．are better at single sportsD．give clear directions to others（4）From the passage，we can learn that left﹣handers．A．may be more talkative and outgoingB．are ordinary people like right﹣handersC．might remember everyday things betterD．no longer need to use right﹣handed tools12．An App for ParkingIs it very difficult for you to park your car when you go out？Don't worry．Parking Insider can help you．Parking Insider is a smart app with a mobile wallet．You can use it to help you park your car quickly and pay for the parking in a really short time．The app also invites users to earn free minutes of parking by taking pictures of free parking spaces．The app uses the photos to make a heat map．The map lets other users find open parking spaces more easily．If you want to use the app，you should be one of the clients（客户）of Deutsche Bank．As a client ofDeutsche Bank，you can have an account to pay for your parking through the app．You'd also need to drive Mercedes﹣Benz，a smart car or other Daimler products．To give better service，the makers of the app are trying hard to be partners with other banks and car companies．The app is very popular now，but it has to face plenty of competitions．Cities are making their own parking and paying apps．There are a number of companies already focusing on the issue，too，including Park Now and PayByPhone．（1）What is the Parking Insider？A．It's a car company．B．It's a mobile wallet．C．It's a smart app．D．It's a bank card．（2）What does the Parking Insider use pictures from users to do？A．To earn free minutes of parking．B．To give users better service．C．To make a map which helps
