When angrily opening thescreen door with my foot, I kicked back about a 12-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 delivered a spanking (打屁股) for it. My parents 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 constantly 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 stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.4. When the author damaged the door, his parents ________.A．gave him a spankingB．left the door unrepairedC．scolded him for what he had doneD．told him how expensive it was5. The underlined word “remorse” in Paragraph 1 most probably means________.A．regret B．joy C．anger D．notice6. The experience may cause the author ________.A．to hide his anger away from othersB．not to go against his parents’ willC．to have a better control of himselfD．not to make mistakes in the future7. What is the main idea of this text?A．Adults should ignore their children’s bad behavior.B．Parents are the best teachers of their children.C．Patience is the key to becoming a better person.D．One learns most when shown the result of his/her action.Your math teacher wears clothes made in 1985 and always mispronounces your name. Your English teacher loves to start classes with quick quizzes. It can be hard to think of these givers of grades as real people. But they eat pizza, watch movies and enjoy sports on weekends, just like you. So how can you get along well with your teachers?You can do a lot of things to develop a good relationship with your teacher. First, do the obvious things: Show up in class on time with all tasks completed. Stay focused, be respectful and ask questions. Second, show an interest in the subject. Obviously, your teachers are really interested in their subjects, or they wouldn’t have decided to teach them! Show the teacher that you care about the subject—even if you’re not a m ath talent or fluent in French—and send the message that you are a hard-working student.You can also schedule a private meeting in a teacher’s free time. Use this time to get extra help, ask questions, ask for information about a career (职业) in the subject or talk about your progress in class. You may be surprised to learn that your teacher is a bit more relaxed when only facing you than when teaching in front of the whole class.What if you just don’t like the teacher? When it comes to working with teachers, one’s characteristics can come into play just as they can in any other relationships. People just naturally get along better with some people than with others; it’s impossible to like everyone all the time. Learning to work with people you don’t like is a good interpersonal (人际的) skill to have in life, no matter what your goals are.Teachers are there for more than just homework; they know about more than their subject matters. They can help you learn how to behave as an adult and lifelong learner. Undoubtedly, there will be a few teachers along the way who you’ll always remember—and who might change your life forever.8. What is the purpose of the first paragraph?A．To tell us teachers’ appearances.B．To offer an example.C．To draw out the topic of the passage. D．To introduce one of the key characters. 9. Hou can students develop a good relationship with their teachers?A．By learning as many subjects as possible. B．By respecting other students in class.C．By finishing their homework on time. D．By developing personal interests.10. What is important when working with teachers you don’t like?A．Your characteristics. B．Your interpersonal skills.C．Your career goals. D．Your grades in exams.11. What can we learn from the last paragraph?A．Teachers can help you grow up. B．Teachers are all lifelong learners.C．Teachers should set enough homework. D．Teachers tend to change you completely.From Black Beauty to The Chronicles of Narnia, films and books have often shown the friendships that can develop between humans and horses. Lots of real-life stories have shown that horses seem to have a special understanding of humans. However, until a recent study, nobody knew if horses really recognized different human emotions.A team of researchers set out to see what horses can understand. They used a test that is often used to see how much babies understand about the world around them.The team brought 28horses into a room, one by one. Each was shown a picture of a happy human and a picture of a sad human. At the same time,a recording of a happy or sad voice was played.The test showed that horses can recognize different emotions by looking at facial expressions and hearing the tone of people’s voices and matching the two up.When the voice didn’t match up with the picture, the horses seemed to be puzzled: they looked at the picture for longer, as if they knew that something wasn’t right. However, the researchers still don’t know if the horses actually understand what it is to be sad or happy.Scientist Océane Liehrmann, from the University of Turku in Finland, worked on the study. She said,“You could imagine that they have a particular box in their mind labelled (贴标签)’human sadness’ containing the characteristics of both a sad face and a sad voice.”It’s also though t that horses prefer to spend time around happy people because they spent longer looking at the pictures of happy people.The researchers now want to see if horses can recognize other negative human emotions.12. Why did the author mention two films at the beginning?A．To lead the readers to the topic. B．To introduce the films to the readers.C．To compare the films with the real life. D．To advise the readers to relaxthemselves.13. The researchers want to find out in the study whether horses canA．hear different sounds B．communicate with humansC．recognize different pictures D．understand human emotions14. When finding the picture didn’t match up with the voice, how did the horses feel?A．Sad B．Happy. C．Puzzled. D．Satisfied.15. Why do the researchers think horses like to be around happy people?A．Because horses like to hear loud laughter.B．Because horses can recognize people’s sad emotions.C．Because horses spent more time on the pictures of happy people.D．Because horses understand what it is to be sad or happy for people.Habits to Be a Highly Effective StudentSome students are able to get straight A’s and at the same time serve as the president of three clubs. However, some students struggle to keep their GPA(grade point average)above 3.0. 16 Althoughit’s true that everyone’s IQ is different, good study habits are very important. Here are several habits you should adopt to get good grades.17 If you haven’t had a “planner”, get one. Many people use their computers and smart phones to make a schedule. The problem with that approach is that they are major distractions(使人分心的事物). Instead, get an old-fashioned paper and pen planner.Create a weekly schedule. 18 Include time that will be spent eating, sleeping and doing anything not related to schoolwork. That way you know exactly how much you can achieve each day.Take frequent, short breaks. Taking a break from studying for 15 minutes every hour will help keep you refreshed. 19 If you don’t take a break, you may find yourself daydreamin g or even falling asleep. Take some time for some water, a snack or a quick chat with a friend.Take care of yourself. During the final exam week, it is common for students to fall behind on sleep and meals. Make sure you get a good night’s sleep and have regular meals. Studying while you are hungry or sleepy is ineffective and will slow you down in the long run. Also try to make the time for family and friends. 20As French author Andre Maurois once said, “Without a family, man, alone in the world, shakes with the cold.” Indeed, families who give us love and _______are an important part of our lives. But even in a loving family,_______can’t be avoided.One day, I was doing my homework and my sister_______.Busy with homework, I didn’t talk to her and just kept working: But when I took a_______, I turned my head to the place where my sister was sitting._______, I found my notebook had a lot of messy drawings on it.At that time, I was full of _______and walked out of my room, shouting at my sister. “You are really a_______and I hate you.” Hearing the words, my sister_______out crying and tried to explain her behavior. But I_________ since I didn’t want to hear a w ord from her. The ________afterward lasted for a long time________us. To solve the problem, my father brought me to the living room and asked: “Have you noticed what the drawing is on your notebook?”I shook my head. Then, under the ________of my father, I looked at it carefully,it________,“Happy birthday”. At that moment, I knew how ________I was. Though drawing on my notebook wasn’t right, my sister’s love and __________ were sincere. Feeling guilty, I said sorry to my sister. Instead of staying angry, she smiled back at me.21.A．wisdom B．truth C．soul D．warmth 22.A．misunderstandings B．expectations C．competitions D．dislikes 23.A．left B．entered C．led D．met24.A．test B．task C．text D．rest25.A．Fortunately B．Disappointingly C．Shockingly D．Thankfully 26.A．anger B．hunger C．anxiety D．sadness 27.A．storyteller B．house-cleaner C．troublemaker D．performer 28.A．burst B．burnt C．devote D．beat29.A．amused B．refused C．allowed D．turned 30.A．quarrel B．fight C．lecture D．silence 31.A．among B．within C．against D．between 32.A．requirement B．campaign C．concern D．strategy 33.A．spoke B．told C．said D．talked 34.A．indifferent B．inconsiderate C．inactive D．independent 35.A．absence B．intentions C．attitude D．permission阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

I must have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and re ad it myself.I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything.I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an importa nt part of my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.1. Why did the author want to grab the newspaper out of mom’s hands？A．She wanted mom to read the news to her.B．S he couldn’t wait to tear the newspaper apart.C．She couldn’t help but stop mom from reading.D．She was eager to know what had happened.2. According to Paragraph 3, the author’s reading of road signs shows___________.A．her own way to find herselfB．her eagerness to develop her reading abilityC．her growing desire to know the world around herD．her effort to remind mom to obey traffic rules3. The author takes novel reading as a way to___________.A．explore a mysterious landB．develop an interest in learningC．get away from a confusing worldD．learn about the adult world4. What could be the best title for the passage？A．The Pleasure of Reading B．Growing Up with ReadingC．The Magic of Reading D．Reading Makes a Full Man3. A new concept vehicle, Pod was introduced by Toyota and Sony at the Tokyo motor show. The car is intended as a four-wheeled friend. It aims to provide affection, sympathy and encouragement. Like a dog welcoming its master, the car sits up, wags its tail and recognizes its owner’s presence using hydraulics (液压装置) and a multi-coloured LED display panel (引擎) across the front.While on the road, the car constantly monitors the driver’s mood with pulse and sweat (汗) sensors on the joystick (操纵杆). Cameras fixed on the eyes keep watch for any sigh of drowsiness. If a driver appears to be losing his or her cool, Pod will display warnings, play soft music and blow cold air at the face. Drivers are shaken awake with loud music and a shaking chair.To improve driving skills, Pod uses a comparison to score drivers, offer advice and rank all Pod owners. Toyota states that the car will eventually be able to learn its owner’s likes and dislikes by monitoring passenger conversations. If the car hears a favorite song being discussed, it will download the track from the Internet and play it without being asked. It will also recommend (推荐) restaurants that might suit the driver’s taste and take photographs of passengers when they sound particularly happy.In keeping with the moodiness that is the car’s main selling point, Pod expresses a form of road anger. If a driver brakes or swerves (急转弯) suddenly, the LED panel shows an angry red and the tail rises at the back.Anger is one of the car’s ten “emotional states”. Another is sadness—a blue front with tear-shaped lights seemingly dropping from headlights—which appears after a flat tyre or when gas is low. “We wanted to show that the cars can be cheerful and entertaining,” said Yasunori Sakamoto, part of the Toyota design team. Mr Sakamoto said Toyota has no plans to put Pod on the market. Sad, really.1. The underlined word “drowsiness” in Paragraph 2 means _________.A．fear B．boredomC．excitement D．sleepiness2. According to the text, Pod can ________.A．rank the restaurant nearby B．recommend a song to passengerC．have a conversation with drivers D．test the driver’s driving skills3. If the new concept vehicle is running out of gas, _________.A．the LED panel turns redB．the tail rises at the back of the carC．the front lights turn blue and look like tearsD．the car stops and shake with loud music4. What is the author’s attitude towards Pod?A．Supportive. B．Doubtful.C．Negative. D．Curious.4. The Canadian government announced a plan to ban single-use plastics as early as 2022. As someone who performs research on plastic pollution, I see this as a positive step forward. However, I wonder whether it will go far enough.Some people may feel that this announcement is simply a “feel-good measure” and a distraction from bigger problems such as the climate disaster. The truth of the matter is that plastic pollution and the climate disaster are signs of the same disease. As much as 8% of global oil goes directly to plastic production—a figure that doesn’t include the transportation of single-use plastics to global markets, the energy used to transport plastics to landfills and the energy used to sort or recycle things.In the past years, some bans have actually resulted in an increase in other forms of waste. For example, paper bags may be seen as a sustainable (可持续的) choice since, unlike plastics, paper breaks down in the environment. However, a paper bag has a carbon footprint three times that of a plastic bag and is still “single-use” just as much as a plastic bag is.Adopting (采用) a science-based method, which the government has promised, will ensure the ways of using single-use plastics are more sustainable. I’m, however, concerned about the announcement because “as early as 2022” is very different from “by 2022”, which has a strict timeline. If we’r e truly going to carry out an effective ban on single-use plastics, our government will need to spend a large amount of money on innovation (改革) and research into sustainable materials and our waste treatment system to prevent plastics from going into our oceans or landfills.So the question remains: is this announcement simply smoke and mirrors, to hide a lack of determined action on both plastic waste and the climate disaster, or is this a real effort that will be carried out to stop the production of single-use plastics? We will have to wait and see.1. How does the author feel about Canada’s new plan?A．She is more excited than worried. B．She never believes in Canada.C．She considers it a great success. D．She has mixed feelings about it.2. The purpose of Paragraph 3 is to_________.A．stress paper bags are sustainable materialsB．explain paper bags are greener than plasticsC．prove some measures are unsatisfactoryD．show paper bags are no different from plastics3. Which aspect of the announcement makes the author concerned?A．Its coming a little too late. B．Its lacking scientific support.C．Its having no strict timeline. D．Its appearing far from practical.4. What is mainly talked about in the text?A．Canada’s efforts to reduce the use of plastic s.B．The author’s views on Canada’s single-use plastic ban.C．Reasons for the author’s criticism of Canada’s new plan.D．Similarities between plastic pollution and the climate disaster.5. Pick up your gameA youth soccer coach, Hugo Grajeda, director of Pro Youth Soccer Academy in Chester, New York, shares some tips to help you improve your soccer skills.Start with basic drills. “Go outdoors, get a ball, and keep it close to your feet,” Grajeda says. “ 1 If you have a backyard, work on shooting.”2 “ It’s a good way of building skills without having the pressure of games. Choose a camp that includes building skills and go to one of those. There are plenty of camps that begin right after school ends.”Don’t forget to stretch (伸展). 3 Then do a seri es of stretches to loosen up your muscles. Don’t forget to take a drink of water before you even step on the field. “Water is important, especially in summer,” Grajeda says.Watch the World Cup. Grajeda will be telling his athletes to watch as many games as they can. 4 Then, you should try to bring some of their moves into your own game. “Pick up something that you like and practice it,” Grajeda says.Keep practicing. Practice may not seem like the most fun part of playing soccer. 5 Look for ways to mak e practice fun by adding some competition to simple drills, and don’t be discouraged if it takes time to get the hang of new skills. “If someone were struggling to improve, I would tell them to keep practicing, keep trying. Practice makes perfect.”6.

ＡMy mom just bought me a new bike. Since my cousin Mary didn’t have a bike with her, she walked next to me. I thought that Mary would jump on the luggage carrier(行李架) over the back tire when I was riding. Mom knew exactly what I was thinking. “ Don’t ride the bike with Mary on the back,” she said. “It’s too dangerous. You could kill yourself. Take turns.”I nodded, but I was thinking I could handle this. A few minutes later, I turned right toa wide road. “Jump on the back, ” I told Mary. I rode fast, laughing as the wind blew throughour hair. It was exciting, until the handlebar(车把) started shaking. The front tire dropped into a drain (下水道) and I fell off the bike, still holding the handlebar.My face, hands, and knees crashed into the pavement. The pain in my mouth was unbearable, and I tasted blood. I turned towards Mary who was on the ground, holding her knee and crying. Seconds later, it seemed that my mom’s car stopped next to us. I wanted Mom to say, “Oh, my poor sweetheart. Let me hug you and everything will be fine.”However, my mom only said, “What have you done to your face? Vanessa, look at what you’ve done!” Mom wasn’t the gentle “ I love you, sweetie” type.Sometimes, I thought Mom had no mercy. But in her own way, she was holding me tighter than I could understand—she was teaching me the lesson I needed. “ You did it—deal with it and learn from it. One day, the results will be greater and I won’t be there to help you. Think it out, Vanessa.”21. We can learn from the text that _________.A. Vanessa fell because she didn’t hold the handlebarB. Vanessa and Mary rode the bike in turnC. Vanessa was blown down by the heavy windD. Vanessa and Mary were both injured22.

Vanessa wasn’t eager for her mom’s hug any more.BHealth, Wellness and the Politics of Food9:00—9:45 a.m. Blue TentPanelists (成员): Jami Bernard, David Kamp, Marion Nestle and Peter Singer.Hosted by Denise Gray, science writer for The New York Times.How does what we eat not only affect our bodies, but also the world?

Often people may be awakened by a group of carolers beginning to gather at the house of worship(敬神活动). They return home to make final preparations as to the clothes one must wear and also as to their offering for the Christmas service.The most important part of their Christmas worship service is the love offering. This is the gift in honor of Jesus. At about 8 or 9 o’clock everyone makes their way to the celebration of the birthday of Jesus. Everyone who attends the service goes forward to lay down their gift upon the raised platform near the Communion table. No one will attend the service without giving a gift.Christmas in South Africa is a summer holiday. There is no snow, but it has many flowers, many beautiful varieties of wild flowers being in their full pride.In Ghana, most churches show the coming of Christmas by decorating the church and homes beginning with the first week in Advent, four weeks before Christmas. This season happens to be the time of cocoa harvest, so it is a time of wealth. Everyone returns home from wherever they might be such as farms or mines.In Africa, it is the traditional dinner of turkey, roast beef, mince pies, or suckling pig, yellow rice with raisins, vegetables, and plum pudding, crackers. In the afternoon, families go out into the country and usually there are games or bathing in the warm sunshine, and then home i n the cool of the evening. Boxing Day is also a proclaimed (正式宣布的) public holiday usually spent in the open air. It falls on December 26 and is a day of real relaxation.28.

And before they’ve even got out of bed, most of them check the weather, read the news, and send a text or two to friends. It also appeared that people will check the train times, do their banking and update what they want early in the day.In an average week, the research discovered that users pick up their phone more than 1,500 times to complete different tasks from emails to playing games and posting to social media. And the average smartphone user is on their phone for three hours and sixteen minutes a day. This amounts to almost one full day a week using their phone, so it’s no wonder almost four in ten users admitted feeling lost without their tool.Many owners also admitted to finding themselves using their phone without realizing they’re doing so, with two thirds saying they have managed to log in(登录) and browse(浏览) Facebook without thinking. And surprisingly, four in ten said they have, at one time or another, checked their emails automatically(自动的) without thinking.The study has also showed that our smartphones are now becoming more of a “go-to-gadget”, replacing desktops and laptops, which people only turn to for, on average, 140 tasks in a typical day.32.Tasks carried out on smartphones are about _______ more than those on desktops and laptops.A. 221B. 140C. 1.500D. 8033.

What’s the best title for the passage?A. Are we dependent on our smartphones?B. The functions of smartphonesC. The disadvantages of smartphonesD.
