When angrily opening the screen door with my foot,I kicked back about a12-inch part of the lower left-hand corner of the new screen door.But I had no remorse,for I was happy to be playing in the backyard with my toys.Today,I know if my child had done what I did,I would have scolded my child,and told him about how expensive this new screen door was,and I would have given a spanking(打屁股)for it.They never said a word.They left the corner of the screen door pushed out,creating an opening,a breach(裂缝)in the defense against unwanted insects.For years,every time I saw that corner of the screen,it would continually make me think about my mistake.For years,I knew that everyone in my family would see that hole and remember who did it.For years,every time I saw a fly buzzing(嗡嗡)in the kitchen,I would wonder if it came in through the hole that I had created with my angry foot.I would wonder if my family members were thinking the same thing,silently blaming me every time a flying insect entered our home,making life more terrible for us all.My parents taught me a valuable lesson,one that a spanking or strict words perhaps could not give.Their silent punishment for what I had done sent a hundred stern messages to me.Above all,it has helped me become a more patient person and not get angry so easily.24.What does the underlined word“remorse”in Paragragh1probably mean?A.Regret.B.Hurt.C.Feeling.D.Impression.25.What did the author’s parents do when he damaged the door?A.Giving him a sound spanking.B.Leaving the door unrepaired.C.Scolding him for what he had done.D.Telling him how expensive it was.26.How does the author feel about his mistake according to Paragragh3?A.AngryB.IndifferentC.GuiltyD.Amazed27.The experience may cause the author.A.to hide his anger from othersB.not to go against his parents’willC.to have a better control of himselfD.not to make mistakes in the futureCIn the movie,Alice in Wonderland,Alice comes across a Cheshire eat and asks the cat which road she should take.The eat responds,“Well,that depends on where you’re trying to get to.”Alice replies,“I don’t know.”The cat responds,“Then any road will do.”You see,knowing where you’re going increases your chances greatly of gettingthere,and there is no better way of“GETTING THERE”than setting your goals for the upcoming year.Think of your goals as destinations and the action steps as your GPS guiding and directing you.If you are like many other people,for years you have refused the need to set goals and even laughed at the thought that setting goals and,even more importantly,writing them down have positive effects on your life.However,a closer look might convince you that setting goals is s sensible thing to do.In1979,a class of Harvard MBA students was asked:Have you set clear,written goals for your future and made an action plan to accomplish them?The following will astonish you.Only3percent of the class had written goals and a proper plan,13%just had goals,and an amazing84%had no specific goals at all.Ten years later the members of the class were interviewed once again and the following results will no doubt give the reason for our setting goals.The findings were that the13%who had goals were earning,on average,twice as much as the84%who had no goals at all.And the3percent who had clear,written goals with a plan to achieve them were achieving ten times as much as the total97%combined.Goal setting will increase your chances of arriving successfully at your destination. Remember,always set SMART goals.Goals should be:Specific,Measurable,Attainable, Relevant,and Time-bound!28.Why does the author mention Alice in Wonderland?A.To introduce the topic.B.To recommend the movie.C.To criticize the character.D.To analyze the storyline.29.What does the underlined word“them”refer to?A.Actions.B.Destinations.C.Goals.D.Effects.30.What did the second interview find out?A.People with goals were better paid.B.People with goals ere certain to succeed.C.People with no goals earned the most.D.People with no goals accomplished nothing.31.What is most likely to be talked about after the last paragragh?A.Why we set goals.B.Who can achieve success.C.What an action plan is.D.How to set SMART goals.DBig changes in agriculture are taking place in Singapore.The small,Southeast Asian nation is leading a farming revolution.Singapore covers724square kilometers of land and only one percent of that land is used for agriculture.Food production costs are higher there than the rest of Southeast Asia.As climate change and population growth threaten food supplies,the pressure is on new farmers to answer the government’s call“to grow more with less”.“Whenever I talk about food security in Singapore,I tell people don’t think land-think space,because you can go upwards and sideways,”said Paul Teng,an agriculture professor at Nanyang Technological University.There are more than30vertical(垂直的)farms in Singapore-ones that grow up,not across,the land.Sustenir Agriculture is one of these businesses.Its hydroponic(水栽法的)farm grows non-native foods like cherry tomatoes and strawberries inside buildings under artificial(人工的)lighting.Then it sells the produce to local supermarkets and online stores.Sustenir raised$16million from investors(投资人)last year.The money will be used to expand operations in Singapore and open in Hong Kong.However,not everyone thinks the new technology is best.Egg farmer William Ho says the government should not depend so much on agriculture technology businesses.“Many of them have failed.That’s why I’m always asking the government‘Why don’t you invest in us old-timers?’We are more practical,”he said.Professor Paul Teng said an issue for urban farmers is that the high cost of the technology makes their products too pricey for many people.32.What is the second paragragh mainly about?A.High food production costs.B.Reasons for changes in agriculture.C.Agriculture technology businesses.D.Sale expansion of food markets.33.What is the way to achieve food security according to Paul Teng?A.Expanding farmland upwards.B.Buying more food.C.Developing facilities.D.Investing more money.34.What do we know about the old-timers?A.They work on high-tech farms.B.They benefit from pricey products.C.They reduce production costs.D.They need government’s support.35.What is the author’s purpose of writing this passage?A.To criticize people’s traditional view of farming.B.To support the growth of vertical farming in Singapore.C.To introduce the latest development in Singapore’s agriculture.D.To emphasize the importance of traditional agriculture.第二节阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

A Few Tips for Self-AcceptanceWe all want it… to accept and love ourselves. But at times it seems too difficult and too far out of reach. Where do you start？Here's a handful of ways that will set you in the right direction.__28__ Do not follow the people who make you feel not-good-enough. Why do you follow them? Are you hoping that eventually you will feel empowered because your life is better than theirs? Know that your life is your own；you are the only you in this world.__29__ We are often ashamed of our shortcomings, our mistakes and our failures. Remember, you are only human. You will make mistakes, time and time again. Rather than getting caught up in how you could have done better, why not offer yourself a compassionate(有同情心的) response? “That didn't go as planned. But, I tried my best.”__30__ Write them down in a journal. Begin to train your brain to look at strengths before weaknesses. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today. __31____32__ Turn the page in your journal. Put into words why you feel unworthy, why you don't feel good enough. Now, read these words back to yourself. Feeling upset again？Turn to a page in your journal to your list of strengths and achievements. See how awesome you are?A. Nothing is too small to celebrate.B. Now that you've listed your strengths, list your imperfections.C. Others' encouragement can contribute to your self-acceptance.D. Forgive yourself for mistakes that you have made.E.

Experts agree that there is no substitute for "on-the-ground" experience practicing a new language with native speakers.(B)Increasingly, various phrases have been taking over a good old-fashioned "t hank you" or "you’re welcome" in daily conversations in the United States. While ____31____ (dine)at a restaurant, when a waiter comes by to ask Americans ____32____ .they would like more water or bread, do you notice that they often say " I'm good,” rather than "no, thank you?” When someone thanks them for holding the door open, "n o problem "is almost the same response as "you're welcome”.Are Americans becoming ruder, ____33____ (abandon) traditional polite phrases, or are the words they use now just updated versions of the same emotion?According to Lisa Gache, co-founder of Beverly Hills Manners, the decline of these magic words in our everyday conversation has to do with the preference ___34____ all things casual in our society today.

Doesn’t "no, thank you" sometimes sound a little too formal, perhaps even a little too harsh(刺耳的), ____37____ it begins with a “no”?Emily Post Senning, ____38____ great-grandmother set the standard on manners with the book Etiquette,thought that while the principles of respect and consideration are "universal and timeless, " actual manners change over time and between cultures, ____39____ do the words used to express gratitude and appreciation.It's probably not a bad idea ____40____ (remember)to say "please" and "thank you,” but don’t beat yourself up thinking you're a horrible person if you say "have a good one" instead of "have a nice day.”Section BDirection: Fill in each blank with a proper word chosen from the box. Each word can be used only once. NoteI surveyed more than 30.000 people around the world. These people came from different cultures and were working in various industries. I asked them about how they relate to others: Do they prefer giving or taking?I found that many of them were somewhere in the middle. They fell into a third group, who do something called"matching".If you are a" matcher," you try to keep a balance between giving and taking: "quid pro quo"--I’ll do something for you if you do something for me. That seems like a safe way to live your life. However, is it the most ____41____ approach on a daily basis?____42____ the worst performers among those I surveyed- -regardless of their ____43____ or nationalities ---were the givers.

A. consequently B. significantly C. necessarily D. dramaticallySection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them, there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)April Fool’s Day and Easter Sunday rarely coincide. Since 1900, Easter has fallen on April Fools’ Day for only five times--1923,1934, 1945, 1956 and 2018. Obviously, it's a once-in-a-lifetime chance to play Easter-themed pranks on your children. Here are some suggestions.A treasure hunt with a twistA fantastic Easter Sunday tradition is to do a treasure hunt where the Easter Bunny has left eggs around your house. Each egg has a small written clue or riddle (谜语)directing the children to where they can find the next one. But when April Fools' Day and Easter Sunday coincide, why not leave some carrots in their place, instead of hiding chocolate eggs ?On the third or fourth clue, you can make it appear as if the Faster Bunny has left a note apologizing for eating all the chocolate but saying they hope you enjoy this left-behind lunch.An Easter basket with a differencePrepare an Easter basket for the children, and either wrap it up or cover it up so that the contents can’t be seen. Have a card from the Easter Bunny next to it which they can open first, with a message that the Easter Bunny wants them to have an extra special Easter and so has prepared a special gift for them. But rather than chocolate or sweets, what you've put in the basket is incredibly dull stuff that kids will be completely unimpressed by---new toothpaste, some socks or a packet of batteries.A sticky situation“You' ll need to prepare this in advance. Buy some of the plastic eggs that contain toys. Unwrap them, open them and then carefully glue them shut and re-wrap them. You don't have to be too tidy---your children are going to be thinking about getting to the toy and are not going to be suspicious. Sit back and enjoy them trying and failing to open the eggs.The invisible Easter egg huntThis is an excellent plan if you have a garden. Tell the children there is an Faster egg hunt in the garden and lead them there.Close the back door. Let your children spend ages searching fruitlessly for Easter eggs that you haven't actually hidden. After you have enjoyed a rare ten minutes of peace and quiet indoors, while they get increasingly confused and frustrated, go into the garden claiming to have found a note from the Easter Bunny. The note reads "April Fool."76. The target readers of this passage are ________A. SchoolchildrenB. head teachers in schoolsC. children who have younger siblingsD. parents of young children77. Which of the pranks is most likely to require a large outdoor space?A. A treasure hunt with a twistB. An Easter basket with a differenceC. A sticky situationD. The invisible Easter egg hunt78. Which of the following statements can be inferred from the passage?A. A treasure hunt for carrots is an Easter traditionB. April Fools Day and Easter Sunday coincide every 11 yearsC. Children are usually disappointed at gifts like socks and batteriesD. All of the four recommended pranks require extensive preparations(B)Even now she calls my attention every day to mispronounced words. All teachers of the deaf know what this means, and only they can at all appreciate the peculiar difficulties with which I had to contend.I had to use the sense of touch in catching the vibrations (振动)of the throat, the movements of the mouth and the expression of the face; and often this sense was at fault. In such cases I was forced to repeat the words or sentences, sometimes for hours, until I felt the proper "ring" in my own voice. My work was practice, practice, practice. Discouragement and weariness cast me down frequently. But the next moment the thought that I should soon be at home and show my loved ones what I had accomplished renewed my courage and spurred(激励)me on, and I eagerly looked forward to their pleasure in my achievement.“ My little sister will understand me now, " was a thought stronger than all obstacles. I was filled with joy while I anticipated the delight of talking to my dear mother and reading her responses from her lips. It astonished me to find how much easier it is to talk than to spell with the fingers, and I discarded the manual alphabet as a medium of communication on my part. But my teacher and a few friends still use it in speaking to me, for it is more convenient than lip reading.Perhaps I had better explain our use of the manual alphabet, which seems to puzzle people who do not know us. One who reads or talks to me spells with his hand, using the single-hand manual alphabet usually employed by the deaf. The position of the hand is as easy to feel as it is to see. I do not feel each letter any more than you see each letter separately when you read. Constant practice makes the fingers very flexible, and some of my friends spell rapidly --about as fast as an expert writes on a typewriter. The mere spelling is, of course, no more a conscious act than it is in writing.When I had made speech my own, I could not wait to go home. At last, the happiest of happy moments arrived.79. According to the article, what kind of communication method did the author prefer?A. TypingB. Lip readingC. Finger spellD. Talk80.

Books bought back are processed by the staff and sold to students.(D)Aspirin has long been believed to help prevent heart attacks and strokes(中风).Some studies have shown that it also has a protective effect against certain types of cancer. As a result, some people religiously pop a low-dose(低剂量的) aspirin after breakfast every day (never take one on an empty stomach). But now its status as a wonder drug has come into question, following a meta-analysis of trial evidence.A meta-analysis reviews the results of a large number of trials and can therefore come to more certain conclusions. This latest review was published this May in The Journal of the American Medical Association.It focused on the connection between aspirin use and cardiovascular(心血管的) and bleeding events. It found that the well-known risk that aspirin can cause internal bleeding is as great as the benefits of preventing heart attacks and strokes. In some cases, the risk even outweighs the benefits.Aspirin thins the blood, thus helping to prevent blood clots (血栓). For his reason, it is a good drug for protecting people who have already had a heart attack or stroke from having another. However, the 164,225 people in these trials had no history of cardiovascular disease. They were monitored for an average of six years, during which time they took a daily aspirin or placebo(安慰剂).Among those who took aspirin, there were about 11% fewer heart attacks and strokes but 43% higher likelihood of a major bleeding episode in the stomach, brain or intestine(肠道).Dr Sean Zheng, a cardiology(心脏病学) researcher at King’s College London, said that taking a daily aspirin couldn’t be recommended for healthy people. But there might still be a case for pe ople with a higher risk of a heart attack or stroke, he added. However, it would be important to consider the bleeding risk.“Aspirin use requires discussion between the patient and their physician, with the knowledge that any small potential cardiovascular benefits are weighed up against the real risk of severe bleeding." he said.The findings reflect the average likelihood of bleeds or heart attacks among the patients in all the trials. There will be people among them who would be better off taking aspirin and those who will be worse. It's yet another situation where we need to weigh up our individual risk and benefit--- maybe with the help of an understanding GP.87. Which of the following is NOT a reason why some people take an aspirin every day?A. They want to lower their risk of having a heart attackB. They hope to protect themselves against some cancersC. They want to ensure they don't have a sick stomachD. They aim to make sure they won't suffer another stroke88. What can be concluded from the recent meta-analysis?A. That aspirin does more harm than good to the human bodyB. That aspirin frequently causes internal bleeding because it thins the bloodC. That previous research into the effects of aspirin on the human body was unreliable.D. That taking aspirin is not worth the risk or those with no history of heart tacks or strokes.89. What should people do before taking aspirin, according to the article?A. To have a thorough physical examinationB. To ask for others' opinions on the internet.C. To read the findings of new studies on aspirinD. To talk with a doctor familiar with their condition90. The article was probably written by ________A. the director of a hospitalB. a public health journalistC. the CEO of a medical companyD. a representative for an insurance companySection CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentenceJeff Bezos Reveals His No. 1 Leadership SecretAmazon has reached what its founder and CEO Jeff Bezos called "an interesting milestone.” The retailing giant so highly associated with books and then music and video, now has tens of millions of products in stock and a majority are non-media goods, from drills to tennis balls to almost anything else that can be shipped.____91____ The 48-year-old has officially transformed Amazon, which he founded in 1994, from an online bookstore that sells other stuff to a retailer---and business services provider---that once sold mostly books. Amazon's stock is up 397 percent in the last five years.So, what's behind the success of the world’s largest online retailer? ____92____ Bezos regularly leaves one seat open at meetings and informs all attendees that they should consider that seat occupied by their customer---the most important person in the room.Always trying to find out what customers want, Bezos is even stricter about that customers don’t want. They hate delays, defects and out-of-stock products, so the company constantly looks to make them as rare as possible. ____93____ Amazon data show that a 0.1 second delay in page loading can translate into a one percent drop in customer activity.But great customer service doesn’t fully explain Amazon's extraordinary success. For Bezos,adata driven customer focus encourages him to take risks to innovate. Amazon's kindle, for example, came into being because Bezos believed millions would want an e-book reader that could download any book within 60 seconds. ____94____ Engineers were free to solve technical challenges as they saw fit, only needing to make it right for consumers.Efficiency ---- cheapness, in the eyes of Amazon’s critics---is also an important part of the Amazon culture. In fact, Bezos liks the two. In 2009, Bezos declared that Amazon had begun fighting against waste. The more he could get rid of needless costs, the easier it would be to deliver rock-bottom prices to customers.V.

As a quiet and shy girl, I feared improvising in front of strangers. However,I knew I wanted to work as a science communicator after finishing my Ph.D., so it seemed like a perfect opportunity to learn how to speak and communicate with others effectively. I signed up, knowing the experience would give me help.During our first class, we learned an important concept of improvisation: “yes, and.” It means that, as improvisers, we’d better accept what fellow performers say. If someone says that rhinos (犀牛) are librarians, for example, then rhinos are librarians. We do not question the logic; we say “yes” and then continue with the scene as if nothing is wrong.The first few scenes were hard, but as weeks turned into months, I became more comfortable andeven started to enjoy our classes. I became better at listening, relating to my conversation partners, and communicating clearly in the moment. Once when I was giving a presentation about my science, an audience member surprised me with a question that didn’t grow out of the information I’d presented. Instead of getting confused and nervous, I took the “yes, and” approach—accepting the question and letting my mind focus on why it was asked. That helped me find an appropriate answer. I got pretty excited about it.The benefits of improvisation go beyond communication. Before attending the class, I would get stuck when my experiments produced unexpected data, thinking that I had made a mistake. But now, instead of getting discouraged, I will stay open to the possibility that the results are real, keep exploring the data and end up identifying a new type of cell—one that isn’t behaving as expected.I think all scientists can benefit from this lesson. If the data say rhinos are librarians, then it’s worthfindingout whether rhinos are, in fact, librarians. As scientists, our job isn’t to challenge data that support a preconceived (先入为主的) story, but to say “yes, and.”4. Why did the author attend the improvisation class?A. To get a different experience.B. To finish her Ph.D. at university.C. To give up her job as a science communicator.D. To improve her speaking and communicating ability.5. What was the author’s change after attending the improvisation class?A. She formed her own idea quickly.B. She came up with lots of creative responses.C. She paid more attention to the logic of answers.D. She became a good listener before giving an opinion.6. The author mentions applying the “yes, and” approach to her scientific experiments to ______.A. explain the process of using the methodB. prove the benefits of the improvisation classC. share her own research experiences with readersD. attract fellow scientists to attend the improvisation class7. What can be inferred about scientists from the last paragraph?A. They should attend the improvisation class.B. They should question all preconceived ideas.C. They should carry on research by admitting earlier data.D. They should try to improve their professional knowledge.CSurfing the Internet for fun will make you a better employee, according to an Australian study.The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author Brent Coker said, “Surfing the Internet at times helps increase an employee's attention.”“People need to relax for a bit to get back their attention,” Coker said on the university's website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day's work, and as a result, increases productivity (生产效率),” he said.According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software toblocktheir employees from watching videos, using social networking sites or shopping online,” said Coker. “That's not always a good idea.”However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.8. What does the University of Melbourne study mainlyshow?A. People who surf the Internet are good employees.B. Not everyone surfs the Internet for fun during office hours.C. The Internet is becoming more and more important in people's life.D. Surfing the Internet for fun at times during office hours increases productivity.9. Which of the following is NOT mentioned in the passage as one of the most popular surfing activities?A. Watching videos.B. Reading online news.C. Reading online novels.D. Playing online games.10. The underlined word “block” in Paragraph 4 means “________”.A. stopB. organizeC. protectD. separate11. What can we infer from the last paragraph?A. Those who never surf the Internet have the lowest productivity.B. Spending too much time surfing the Internet reduces productivity.C. Most people don't surf the Internet in moderation during office hours.D. People should spend as little time as possible surfing the Internet.DNewspapers in Great Britainvarygreatly in their ways of carrying the news. There are serious papers for those who want to know about important happenings everywhere, both at home and abroad. There are popular newspapers for those who prefer entertainment to information.The London newspaper that is best known outside Great Britain is probably the Times. It began in 1785, and has a high reputation for believable news and serious opinions on the news. It calls itself an independent paper, which means that it does not give its support to a particular political party. Its leading articles give the opinions of the editors, not those of the owners of the paper.Letters to the editor are printed in the newspaper. These parts of the Times are always interesting. Most of the letters are serious subjects. But from time to time there will be long letters on the subject which is not at all serious, perhaps on a new fashion of dress, or the bad manners of the young people, compared with manners of thirty years ago.12. If you want to get pleasure, please buy yourself _________.A. a serious newspaperB. foreign newspaperC. any independent paperD. a popular newspaper13. The Times has been famous to outside Great Britain for ________ years.A. 19B. 85C. 236D. 22914. The Times is an independent paper because ________.A. it supports no political partiesB. it is not controlled by the British GovernmentC. it gives special support to all the political parties.D. the editor’s opinions are not examined by the owners of the paper15. The underlined word “vary” in the passage probably means “_________”.A. improveB. compete with each otherC. are differentD. keep in touch with each other第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The oh-ohs. The 21st century. That would make you young, creative, connected, global, and no doubt smart. Maybe good-looking, too. Right? But what do other people think about your generation?Some adults worry that you’re more interested in the screen in front of you than the world around you. They think of you as the “face-down ge neration” because you use your phone so much and they wonder how you will deal with school, friends, and family. Are today’s teenagers too busy texting and taking selfies to become successful in real life—or “IRL”, as you wouldsay?Other adults worry that today’s youth are spoilt and don’t want to face the challenges of adult life. Many children born in the 1990s and 2000s were raised by “helicopter parents”, who were always there to guide and help their children with a busy schedule filled with homework and after- class activities such as dancing, drawing, or sports. With parents who do everything for them, today’s youth seem to prefer to live like teenagers even when they are in their 20s or 30s.With these taken into account, does the face down generation need a warning? Well, probably not. The fact is that many of today’s teenagers are better educated and more creative than past generations. They seem to be enthusiastic and willing to become leaders. More young people than ever volunteer to help their communities. There are also brave young people such as Malala Yousafzai, the teenager who won the 2014 Nobel Peace Prize for pushing girls’ rights to go to school. So if you’re one of the oh-ohs, there are reasons to be hopeful about the future. Things are looking up for the face-down generation. Chances are that you will do GR8 (great) and LOL (laugh out loud).24.Which of the following words EXCEPT can be used to describe the oh-ohs? A．Creative B．Caring.

Suddenly, it was difficult for me to accept that the roles were now changed—my mother became my child, and Ibecame her mother. I became impatient, argued with her, once I even yelled at her. Gradually, I was used to this kind of life. Now I am able to deal with her and the situation better. I have learned a lot of life lessons from the experience.My mother reacts very sensitively to my feelings. That is typical of Alzheimer’s patients. When I visit her, feeling busy and tense, she reacts immediately, takes on my mood, and becomes nervous and negative. But when I appear cheerful and attentive, she is happy. This has taught me to pay more attention to my own feelings when I am with other people.I always thought I was very tolerant, but in reality, my tolerance ran out as soon as someone turned away from what I considered “right”. With my mother I can now really be tolerant. Through her illness she has developed a childlike tactlessness(不得体). Eating out in restaurants, for example, is a bit embarrassing when she shouts at the waiter that the food is so bad or talks about people at the next table in a loud voice. Of course I make sure that my mother doesn’t hurt anyone, but I’ve stopped complaining about others and have become more tolerant.I have als o learned that everything has special value. When my mother got sick I didn’t want to burden my two daughters with it. They are young and have enough going on with their education, and starting their careers. I felt that it was simply my job as my mother’s daughter. The most wonderful discovery I’ve made through my mother’s disease may be that my children not only offer to help me when they sense that I’m feeling unbearabl e, but that they take care of my mother on their own actively. They visit her often, play cards with her, and look at photo albums together with her. It shows me that it’s all worth it.27.Which of the following is common behavior ofAlzheimer's patients?A Curiosity about everythingB Sensitivity to others' moodsC.Fear of strange peopleD.Quick reaction.28.The underlined word overwhelmed "in the last paragraph is closest in meaning toA. concernedB. scaredC. embarrassedD. stressed29.We can infer from the passage thatA.the writer accepted the role change immediatelyB.the writer only paid attention to her mother's feelingsC.The writer has a great sense of responsibilityD the daughters took over the responsibility to look after their grandmother30.This passage is mainly aboutA.how I cared for my sick motherB.how I became more tolerantC.what I have learned from my mother's illnessD.why I am feeling overwhelmedDWe lead very busy lives and we too easily forget how hard it was for us to focus on homework when we were in school. Now that we have jobs to do, food to buy and cook and other errands to run, even I sometimes think it would be a welcome change to have to sit down and quietly read and write with no distractions. But in case you don’t remember —— homework is pretty much everychild's least favorite thing to do. In the age of Netflix, Snapchat and wifi, the distractions are almost endless. It can sometimes almost be too hard to even keep up with all the new tech advances our kids are using, so how can we make sure that those advances take a back seat to our children's education? Here are some ideas.There's no point in stopping the reality that young people are going to focus on their phones and tablets instead of other things at times. Your best way is to accept, actually the tech sector continues to be the most profitable and fast-growing industries and that's unlikely to change fast. There are ways to use technology to help your kid do homework. Ask your teacher and school staff what apps and websites they’re using to teach lessons and supplements（补充）them with at-home activities as well.Even though technology has changed, the basics haven't. If you want to read, write and think properly, you need to have peace and quiet and the ability to focus, right? Well, your kids are just the same, Try and find a space in your home to enable your kids to do work away from televisions, the Internet or other distractions. Let me be clear: this shouldn't be a prison. I feel like I'm my most productive working alone in an office or at a busy cafe with my headphones on, Getting lost in other realities helps my creativity grow. Placing kids in isolation (独处) can often have a harmful effect and doesn't always equal being more productive.I feel like "getting engaged (参与) "is always a big part of my advice for parents on just about everything. How can you make sure your children are being successful if you have no idea what they're doing? How can you be sure they're doing it right if you don't know what is the correct answer? What do they need? You should be in touch with their teachers have a sense of where the lessons are going, what kinds of tasks are being given and what success looks like in the classroom, Knowing all of that is key to your child's success, especially when matched with some encouraging praise and helpful tips on how he can keep going. Thinking about how your child is best motivated (激励) by other things and using those methods here reasonably isn't a bad idea.And if by chance you’re having trouble solving that Math problems or understanding a sentence, don't fear —— you're not alone. Use the school staff, other parents and friends as your support. Better to seek help than do nothing.We all know that homework isn't exactly the most entertaining way anyone spends their time and sometimes we can't help but feel that since we left school, we're done with homework forever. But the circle of life plays out in all times and it's up to us to make sure that we pass on the lessons we've picked up and that while homework might seem dull. It's how we build skills, learn real lessons and get on the road to greatness. That greatness is on the inside, it's up to us as adults to enable the young people to bring it out. The key to achieving greatness is to take a lifelong learning.31.What is the author's attitude towards new tech?A.It affects parents’ everyday life.B.It should be kept out of children's reach.C.It can benefit student's education.D.It makes homework easier.32.Which of the following ideas might the author agree with?A.Homework should be made entertaining.B.Parents should know what motivates their children best.C.Students should do their homework independently.D.School staff should help parents on n ew tech.33.While parents get engaged in their children's homework, theyA.Must be better at all the lessons.B.Needn't make sure that their children are being successful.C.can teach their children by themselves.D.should know as much as possible about it.34.What can be inferred from the last paragraph?A.Children should achieve greatness on their own.B.Parents and their children should learn from each other.C.Children can hardly succeed without parents efforts.D.Parents can only obtain skills by helping their children.35.Which section of a magazine is this passage most probably taken from?cationB.HealthC.Technology.D.Science.第二节：七选五（共5 小题：每小题2.5 分，满分12.5 分阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
