Dining—Sushi Chef in Town22. Which of the following is TRUE according to the text?A. Scottish dancing is so interesting and easy that it never tires you out.B. The performance given by the American jazz band won’t last quite long.C. Sushi is not popular in Shanghai as it is a kind of traditional Japanese food.D. It is more interesting to visit Shanghai Museum for the exhibits from Egypt.23. From the text we may learn that Kamura is ___________.A. an instructorB. a waitressC. a cookD. an artistBIf you are planning on travelling, there are a few simple rules about how to make life easier both before and after your journey.First of all, always check and double-check departure(出发) time. It is surprising how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said thatthe plane left at 10:50. When I arrived at the airport, the person at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.The second rule is to remember that even in this age of credit cards (信用卡), it is still important to have some local money in cash (现金). Once I arrived at a place at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi but because I had no dollars, I offered to pay in pounds instead. “Listen! I only take real money!” the driver said angrily. You can imagine how terrible I felt at that moment.The third and the last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.24. Where is the writer most probably from?A. Britain.B. The USA.C. Italy.D. Greece.25. When the writer found he had no dollars to pay the taxi driver, he ________.A. asked the driver to give him a free rideB. offered to pay in poundsC. gave the driver some fake (假的) moneyD. tried to pay by credit card26. Generally, in May the weather in London is ________.A. warm and dryB. cold and dryC. hot and wetD. cool and rainy27. The writer mainly tells us ________.A. how to make life easierB. how to be well prepared for atripC. how to enjoy ourselves on the tripD. how to schedule our tripCSweetest Day is celebrated on the third Saturday in October as a day to make someone happy. It is an occasion which offers all of us an opportunity to remember not only the sick, the aged, and children who have lost their parents, but also friends, workmates, relatives and neighbors whose helpfulness and kindness we have enjoyed.Over 60 years ago, when a Cleveland man noticed that some people, such as children who lost their parents and patients who lay in bed, too often felt forgotten and neglected, he developed in his mind the idea of showing them that they were remembered. He did this by giving them small gifts. With the help of his friends and neighbors, he gave those people small gifts on a Saturday in October. During the years that followed, other Clevelanders began to take part in the celebration, which came to be called “Sweetest Day”. Over time, the Sweetest Day idea of spreading cheer to the poor, the sick and children who had lost their parents was broadened to include everyone, and became an occasion for remembering others with a kind act or a small gift. Soon the idea spread to other cities all over the USA.Sweetest Day is not based on any single group’s religious beliefs or on a family relationship. It is a reminder that a thoughtful word or deed enriches life and gives it meaning.Because for many people remembering takes the form of gift giving, Sweetest Day offers us the opportunity to show others that we care, in a positive way.28. What can we learn from the first paragraph?A. Sweetest Day is a day to make others happy.B. Sweetest Day is just an occasion to care about disabled people.C. Sweetest Day is an occasion for lovers to express love.D. Sweetest Day is celebrated on the third Sunday in October.29. What is Cleveland?A. An island.B. A country.C. A village in England.D. A city inAmerica.30. What do most people usually do to show their care to others according to the passage?A. They give money.B. They give gifts.C. They send regards.D. They offer help.31. The underlined word “neglected” in the second paragraph means “”.A. rememberedB. hatedC. paid little or no attention toD. disappointedDToday almost everyone knows computers and the Internet. If I ask you what the most important in your life is, maybe you will say “computers and the Internet”.The first computer was made in 1946. It was very big but it worked very slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today”.The Internet came a little later than computers. It is about twentyfive years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, go shopping, play games or ma ke friends.Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making “unreal friends” that they can’t put thei r heart into study. Many of them can’t catch up with others on many subjects because of that.We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.32. When the computer was invented, it was .A. large and worked quicklyB. small and worked slowlyC. large but worked slowlyD. small but worked quickly33. The Internet was born in about .A. 1960B. 1971C. 1980D. 198534. Which of the following is TRUE?A. Few students like g oing into the Internet.B. Students use the Internet to make “unreal friends”.C. These “unreal friends” always meet each other.D. Students know the friends on the Internet very well.35. What does the writer think of the Internet?A. It is wonderful.B. It can make students study harder.C. It is not good for students.D. It is helpful, but we can’t do everything on it.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

A little girl, less than two, was pushing her stroller (婴儿车) across the road. It was Sunday morning and traffic was not heavy.I stopped my car at once and ran toward her. This little girl knew enough to run from a stranger. I tried to catch her in order that I could get her out of the road.Suddenly her father came running down a hill across the road from where I had parked my car. He ran right to her and caught her up, saying “bad girl” to her.I picked up the stroller and gave it to him. The father grabbed (抓住) the stroller and walked toward where he came from without a word.I went back and sat in my car for a few minutes with my son. My hands were shaking and tears were about to run out of my eyes. “Do you feel cold, Mom?” asked my son. I just shook my head.After this happened, I thought about how thankful I was. Even though the father didn’t say thank you, I feel that I did something good. Doing something for someone else is pleasing, even when it’s only a matter of being in the right place at the right time.I didn’t really “save” her, but I feel like it was important that I happened to be there. It is sad that I was the only one who stopped. It really made me a little disappointed that no one else stopped to help.21.When the author saw the little girl, ________.A.the girl had lost her wayB.she was driving to work in a hurryC.the girl feared to go across the roadD.there weren’t many cars on the road22.The little girl ran away from the author because ________.A.she wanted to stay on the roadB.she didn’t know the author at allC.she wanted to look for her fatherD.she needed to catch her stroller23.Why were the author’s hands shaking?A.Because she was not feeling well.B.Because she was too excited to keep calm.C.Because the weather was very cold at that time.D.Because she failed to be understood by the girl’s father.24.The author thought that her help was ________.A.really necessary B.worth praisingC.not welcome D.not usefulBSure, it’s good to get along well with your teacher because it makes the time you spend in the classroom more pleasant.And yes, it’s good to get along well with your teacher because, in general, it’s smart to learn how to get along well with the different types of people you’ll meet throughout your life.In fact, kids who get along well with their teachers not only learn more, but they’re more comfortable with asking questions and getting extra help. This makes it easier for them to understand new materials and makes them do their best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school issues (问题).Here is a question:What if you don’t get along with your teachers? In fact, teachers want to get along well with you and enjoy seeing you learn. But teachers and students sometimes have personality clashes (个性冲突), which can happen between any two people. If you show your teacher that you want to make the situation better,he or she will probably do everything possible to make that happen. By dealing with a problem like this, you learn something about how to get along with people who are different from you.However if a certain teacher isn’t your favorite, you can still have a successful relationship with her or him especially ________. Here are some of those responsibilities (责任):Attend class ready to learn.Be prepared for class with the right stationery, books, and completedassignments (作业).Listen when your teacher is talking.Do your best, whether it’s a classroom assignment, homework, or a test.。

Where does this advertisement probably come from?A. A magazine.B. A website.C. A newspaper.D. A textbook.BChina, known as the “kingdom of bicycle”, will see a quick growth in electric bicycle prod uction in the next five years thanks to the country’s efforts to save energy and improve the environment.The output of electric bikes is expected to maintain an annual growth rate of at least 80 percent in the coming five years. China will churn out 30 million electricity-driven bikes in 2010, compared to 9 million bikes last year, according to a report from the Development Research Center under the State Council and other ministries such as the National Development and Reform Commission.The central government wants to reduce the amount of energy consumption (消耗) by as much as 20 percent within the next five years. That would be achieved through the introduction of new sources of energy and encouraging people to save energy, China Daily reported.The smoke from car exhausts (尾气) is a major cause of pollution darkening the sky in Chinese cities, especially Beijing. Industrial experts on Monday, called on the government to come up with more preferential (优先的) measures to spread the use of electric bikes in China.Electric bike production in China accounts for about 90 percent of the world’s total, making China the world’s biggest producer, consumer and exporter of the energy-efficient vehicle, the report indicated. The country last year sold about 3 million electric bikes to foreign countries, a figure expected to double to 6 million in five years. By 2010, the production value of the electric bike industry in China is expected to be 70 billion Yuan (8.6 billion US dollars), almost four times the current level.4. Why will there be a quick growth in electric bicycle production in the next fiveyears in China?A. Because electric bicycles can save the consumer more money.B. Because most people in China can’t afford cars.C. Because the central government encourages people to save energy.D. Because the Chinese government limits the development of bicycle production.5. The underlined phrase “churn out” in the second paragraph has the same meaning as “_____”.A. makeB. sellC. designD. export6. According to the report, ________.A. the output of electric bikes is expected to increase at least 80 percent inthe coming five yearsB. the central government of China wants to increase the amount of energyconsumptionC. China is the w orld’s second biggest producer, consumer and exporter of theenergy-efficient vehicleD. China will produce 9 million electricity-driven bikes in 20107. What is the best title for the passage?A. How to make electric bicyclesB. The world’s biggest pro ducer of electric bicyclesC. China’s quick growth in electric bicycleD. How to save energy and improve the environmentCI could feel the judging eyes of my family burning a hole into the back of my head as I picked up my phone. All of a sudden, the chattering in the living room died and all I could hear was the sound of the turkey sizzling (发出嘶嘶声) in the oven.“Look at her! She’s been on her phone all day long! It’s all your fault! Children will never respect elders if they are not taught how to behave! ” my grandmother shouted.I was very shocked and angry! I opened my mouth to say something, but words failed me and I just sat down quietly on the chair like a mouse in its trap. I thought “Here we go again.” I truly love my family and I would do anythin g for them. I also know that they would do anything for me as well. However, there are moments that make me feel that they are just stuck with me. They all agree on one thing: technology is wrecking me.If I am going to be treated like a child or completely ignored, I will most likely not enjoy your company, and I feel that this applies to (适用于) the majority of the people. So I sometimes simply shut myself in my room and listened to the voices coming from the living room, thinking: They all grew up in a world so different that it amazes me how they have actually gotten this far. They did not have phones or any type of advanced technology, which is both good and bad. Bad because they had almost no type of fast communication, and good because they were forced to interact (互动) with one another, which is something today’s society is lacking in. However, maybe if they made an effort to be aware of how things work nowadays, they would not be so against everything.8. What happened when the author picked up her smart phone?A. Her family laughed at her.B. Her family kept silent.C. She felt like having a headache.D. She smelt something burning.9. The underlined word in the third paragraph probably means ________.A. punishingB. encouragingC. savingD. destroying10. We can infer from the passage that the author felt it hard ________.A. to do something to please her familyB. to satisfy her family’s high expectationC. to get along with her family in some waysD. to move out or break away from her family11. The author uses the last paragraph to show that ________.A. it is her duty to provide her family with a happier life in the futureB. it is necessary to treat each other well in the familyC. it is hard for the older people to accept the advanced technologyD. it is important to strengthen understanding among the familyDThe stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is that history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free.”There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be limited to our mistakes.Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.12. What’s the function of the example in Paragraph 2?A. It reflects that people are concerned about the spread of Ebola.B. It shows the bad effect caused by sharing a story.C. It proves not sharing a story can cause trouble.D. It concludes that one should share a story at a proper time.13. One of the reasons why people are unwilling to share experiences is that _______.A. people sometimes have no courage to share their storiesB. people are used to exposing their weaknessesC. story-sharing highlights the importance of hard workD. some stories make themselves feel uneasy14. Which is close in meaning to the underlined word “uncorked” in Paragraph 3?A. freedB. brokenC. finishedD. untouched15. The writer aims to persuade us to _______.A. be open to people close to you by sharing some secretsB. realize the importance of being honest when making friendsC. remove the dangers that can be caused by untold storiesD. share stories appropriately for the good of others and ourselves第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

We knew we wanted to do something to make a difference.” The amount jumped to $80,000 the following year after the girls teamed up with friends, and the playground was built in 2013. It inspired Kaitlin to found Kids on a Mission, a kid-powered nonprofit organization that has helped hundreds of people living in poverty in the US and abroad.The work overseas started when Kaitlin, then 13, visited El Salvador in Central America. There, she saw people starving (挨饿) and families living in shelters made of cardboard (纸板).“The rooms were smaller than my bedroom, but there would be eight people living in [each one],” Kaitlin recalled. “We also got to se e the rivers that these people were drinking out of, and [they contained] dirty water.”Providing clean drinking water for people living in poverty is now a focus (焦点) for Kids on a Mission. Children and adult volunteers dig wells (井) and also help orphans (孤儿) by providing food and clothes.“Being able to see how much they are suffering but then to give them food –that’s life-changing for us,” Kaitlin said.Kids on a Mission is in the process of giving children larger leadership roles within the organization now that Kaitlin is a junior in high school. She may not play as big of a role in the organization if she moves away for college.“This young lady just understands that by giving and having a huge heart, she’s not only changing the hearts of pe ople in this community, she’s changing the world,” said Jim Yovino, Fresno County Superintendent of Schools.24. Which of the following statements is TRUE?A. Kaitlin was inspired to help the poor when she worked at her father’s organization.B. Kaitlin s ucceeded in raising enough money for a playground with other people’s help.C. It took Kaitlin and her sister two years to raise $80,000 for Rescue the Children.D. Kaitlin started volunteering at Rescue the Children when she was 8 years old.25. What can we learn about Kids on a Mission?A. It was founded by Kaitlin and her sister in 2013.B. It is a nonprofit organization aiming to end poverty in the US.C. It only recruits (招募) children volunteers from Kaitlin’s community.D. It is now focusing on providing clean drinking water to the poor.26. According to the article, Kaitlin ______.A. will continue to lead Kids on a Mission when in collegeB. is now working on improving her leadership skillsC. has positively influenced people in her communityD. has received much financial support for her work from her family27. The article is mainly written to ______.A. call on readers to help people in needB. introduce the work of Kids on a MissionC. show that everyone can make a differenceD. share Kaitlin’s st ory of helping the poorCThis summer, th e UK will honor one of its favorite writers, Jane Austen (1775-1817), by making her the face of the new £10 note. In the 200 years since her death, Austen’s fame has increased from the modest amount she enjoyed in her lifetime to the global fame she receives today.And yet Austen’s work is so very English that it’s rather strange she should be so popular all over the world. Her novels are so of their time that it’s remarkable that she’s still appreciated in this very different age. Her most famous works –including Pride and Prejudice (《傲慢与偏见》,1813), the one for which she is most known –are set in the world of the English gentry (贵族阶层) in the late 18th century. Most of her fiction is about young women of that time. Women of the gentry could not work, so their chances of happiness or even basic living depended upon findinga husband. This is a very serious subject matter, of course, but the joy of Austen’s stories is her ability to make wonderful, but also touching, comedy (喜剧) out of something so serious.Take Pride and Prejudice as an example. Elizabeth Bennet is one of six daughters in a family that struggles with money problems. Her mother wants to marry off as many of them as possible. The pushy and annoying (烦人的) Mrs Bennet is one of the great comic characters of English literature.The main plot (情节) of the novel is driven by the love-hate relationship between Elizabeth and Mr Darcy, a wealthy aristocrat (贵族). At first, they don’t get on. Elizabeth finds Darcy too proud; she feels he thinks he is better than everyone else. She thinks that he looks down upon her family in particular. Darcy, while admiring Elizabeth, believes that she has taken unfairly to him. The pleasure of the novel is reading how these obstacles (障碍) are overcome and how the comical and unexpected ending is achieved.If we think about this story, it’s obvious why Jane Austen is still popular 200 years after her death, and why readers can still identify with (感同身受) characters from the long dead world of the 18th century English gentry. Although there have been many changes since that time, it’s still the greatest challenge in life for men and women to find the partner of their dreams.28. It can be concluded from Paragraph 2 that the author ______.A. believes Jane Austen’s works were ahead of their timeB. thinks that everyone should read Jane Austen’s booksC. has doubts about Jane Austen’s popularity all over the worldD. is surprised that Jane Austen’s books are still so famou s29. According to the article, Pride and Prejudice _____.A. has a sad and unexpected endingB. deals with a serious social issue in a light-hearted wayC. centers on poor people’s struggles in the 18th centuryD. tells readers that everyone can succeed through hard work30. According to the article, Jane Austen remains popular today because ______.A. readers enjoy reading love stories about wealthy aristocratsB. readers are attracted by the way people deal with obstacles in the storiesC. readers can always find something new from her novelsD. her works deal with problems many of today’s readers still face31. The article is mainly written to ______.A. tell us why Jane Austen was chosen to be on the new £10 noteB. introduce the story of Pride and PrejudiceC. explain why Jane Austen is still popular todayD. introduce Jane Austen’s creative writing styleDDo you always strug gle to understand others’ feelings? Perhaps you should listen to your heart.According to a team of scientists at Anglia Ruskin University in the UK, people who are more aware of their own heartbeat are better at understanding others’ emotions. Researchers have long suspected (怀疑) that this ability is important for understanding others’ thoughts and feelings.To test this theory, the British team asked 72 volunteers to count their own heartbeats without feeling a pulse (脉搏). This aimed to see how aware they were of the feelings inside their own bodies.Then, the volunteers were shown video clips of social interactions (互动), which tested their ability to read the minds of the characters.During the clips, th ey were asked questions that required an understanding of the emotions of a certain character –for example, “What is Sandra feeling?” In addition, they were asked questions that did not involve any emotions, such as “What is Michael thinking?” They were also asked non-social questions, like “What was the weather like that evening?”The results showed that those who had counted their heartbeats most accuratelywer e better at answering questions relating to the characters’ emotions. However, there was no link between the ability to feel what’s going on inside your body and questions that did not involve any emotions.Punit Shah, lead author of the study, used an example to explain this: If your colleague Michael is rude toward Sandra in public, your body processes (处理) this by increasing your heart rate. This may make you feel anxious and allow you to understand that Sandra is embarrassed .“If you do not feel yo ur heart rate increase, it may reduce your ability to understand that situation and respond (反应) appropriately,” Shah told The Telegraph. Researchers believed their findings mean it could be possible to make people more empathetic by training them to listen to their heart s.This also lends support to the argument that feelings are, at the very least, deeply rooted in physical sensations (感觉).32. What does the new study find?A. People are better at understanding others’ emotions than thoughts.B. P eople with quicker heartbeats are more sensitive to others’ feelings.C. The ability to feel your heartbeat is important for understanding others’ thoughts.D. Your ability to feel others’ emotions is related to your ability to feel your own heartbeat.33. Which of the following statements is TRUE about the new study according to the article?A. The volunteers were asked to count their heartbeats while watching video clips.B. Researchers designed emotional, non-emotional and non-social questions.C. The vo lunteers were required to describe each other’s thoughts and feelings.D. Researchers trained the volunteers to listen to their hearts and observed them.34. The underlined word “empathetic” in the second-to-last paragraph probably means ______.A. willing to accept ideas that are different from your ownB. not influenced in any way by other people or thingsC. being able to understand others’ feelingsD. willing to help those in trouble35. What can be concluded from the last four paragraphs?A. We react to a situation more slowly when our heart rates increase.B. Physical sensations in our bodies are believed to cause emotional changes.C. Our ability to feel emotions is part of us and can’t be changed.D. How we feel has nothing to do with the state of our bodies.第二节(共 5 小题;每小题 2 分,满分 10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

According to the article, Kaitlin ______.A. will continue to lead Kids on a Mission when in collegeB. is now working on improving her leadership skillsC. has positively influenced people in her communityD. has received much financial support for her work from her family27. The article is mainly written to ______.A. call on readers to help people in needB. introduce the work of Kids on a MissionC. show that everyone can make a differenceD. share Kaitlin’s story of helping the poorCThis summer, th e UK will honor one of its favorite writers, Jane Austen (1775-1817), by making her the face of the new £10 note. In the 200 years since her death, Austen’s fame has increased from the modest amount she enjoyed in her lifetime to the global fame she receives today.And yet Austen’s work is so very English that it’s rather strange she should be so popular all over the world. Her novels are so of their time that it’s remarkable that she’s still appreciated in this very different age. Her most famous works –including Pride and Prejudice (《傲慢与偏见》,1813), the one for which she is most known –are set in the world of the English gentry (贵族阶层) in the late 18th century. Most of her fiction is about young women of that time. Women of the gentry could not work, so their chances of happiness or even basic living depended upon findinga husband. This is a very serio us subject matter, of course, but the joy of Austen’s stories is her ability to make wonderful, but also touching, comedy (喜剧) out of something so serious.Take Pride and Prejudice as an example. Elizabeth Bennet is one of six daughters in a family that struggles with money problems. Her mother wants to marry off as many of them as possible. The pushy and annoying (烦人的) Mrs Bennet is one of the great comic characters of English literature.The main plot (情节) of the novel is driven by the love-hate relationship between Elizabeth and Mr Darcy, a wealthy aristocrat (贵族). At first, they don’t get on. Elizabeth finds Darcy too proud; she feels he thinks he is better than everyone else. She thinks that he looks down upon her family in particular. Darcy, while admiring Elizabeth, believes that she has taken unfairly to him. The pleasure of the novel is reading how these obstacles (障碍) are overcome and how the comical and unexpected ending is achieved.If we think about this story, it’s obvious why Jane Aust en is still popular 200 years after her death, and why readers can still identify with (感同身受) characters from the long dead world of the 18th century English gentry. Although there have been many changes since that time, it’s still the greatest challenge i n life for men and women to find the partner of their dreams.28. It can be concluded from Paragraph 2 that the author ______.A. believes Jane Austen’s works were ahead of their timeB. thinks that everyone should read Jane Austen’s booksC. has doubts about Jane Austen’s popularity all over the worldD. is surprised that Jane Austen’s books are still so famous29. According to the article, Pride and Prejudice _____.A. has a sad and unexpected endingB. deals with a serious social issue in a light-hearted wayC. centers on poor people’s struggles in the 18th centuryD. tells readers that everyone can succeed through hard work30. According to the article, Jane Austen remains popular today because ______.A. readers enjoy reading love stories about wealthy aristocratsB. readers are attracted by the way people deal with obstacles in the storiesC. readers can always find something new from her novelsD. her works deal with problems many of today’s readers still face31. The article is mainly written to ______.A. tell us why Jane Austen was chosen to be on the new £10 noteB. introduce the story of Pride and PrejudiceC. explain why Jane Austen is still popular todayD. introduce Jane Austen’s creative writing styleDDo you always strug gle to understand others’ feelings? Perhaps you should listen to your heart.According to a team of scientists at Anglia Ruskin University in the UK, people who are more aware of their own heartbeat are better at understanding others’ emotions. Researchers have long suspected (怀疑) that this ability is important for understanding others’ thoughts and feelings.To test this theory, the British team asked 72 volunteers to count their own heartbeats without feeling a pulse (脉搏). This aimed to see how aware they were of the feelings inside their own bodies.Then, the volunteers were shown video clips of social interactions (互动), which tested their ability to read the minds of the characters.During the clips, th ey were asked questions that required an understanding of the emotions of a certain character –for example, “What is Sandra feeling?” In addition,they were asked questions that did not involve any emotions, such as “What is Michael thinking?” They were also asked non-social questions, like “What was the weather like that evening?”The results showed that those who had counted their heartbeats most accuratelywere better at answering questions relating to the characters’ emotions. However, there was no link between the ability to feel what’s going on inside your bo dy and questions that did not involve any emotions.Punit Shah, lead author of the study, used an example to explain this: If your colleague Michael is rude toward Sandra in public, your body processes (处理) this by increasing your heart rate. This may make you feel anxious and allow you to understand that Sandra is embarrassed .“If you do not feel your heart rate increase, it may reduce your ability to understand that situation and respond (反应) appropriately,” Shah told The Telegraph. Researchers believed their findings mean it could be possible to make people more empathetic by training them to listen to their heart s.This also lends support to the argument that feelings are, at the very least, deeply rooted in physical sensations (感觉).32. What does the new study find?A. People are better at understanding others’ emotions than thoughts.B. People with quicker heartbeats are more sensitive to others’ feelings.C. The ability to feel your heartbeat is important for understanding others’ thoughts.D. Your ability to feel others’ emotions is related to your ability to feel your own heartbeat.33. Which of the following statements is TRUE about the new study according to the article?A. The volunteers were asked to count their heartbeats while watching video clips.B. Researchers designed emotional, non-emotional and non-social questions.C. The volunteers were required to describe each other’s thoughts and feelings.D. Researchers trained the volunteers to listen to their hearts and observed them.34. The underlined word “empathetic” in the second-to-last paragraph probably means ______.A. willing to accept ideas that are different from your ownB. not influenced in any way by other people or thingsC. being able to understand others’ feelingsD. willing to help those in trouble35. What can be concluded from the last four paragraphs?A. We react to a situation more slowly when our heart rates increase.B. Physical sensations in our bodies are believed to cause emotional changes.C. Our ability to f eel emotions is part of us and can’t be changed.D. How we feel has nothing to do with the state of our bodies.第二节(共 5 小题;每小题 2 分,满分 10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

AOne night in December 2011, a bear came into the city of Vancouver in Canada. It walked through the streets past houses, shops and offices until it found some food in bins (垃圾桶) outside a restaurant and started eating. In the morning, someone saw the bear and called the police. They came with a vet (兽医) from the city zoo, put the bear in a lorry and took it back to the mountains. Luckily, the bear was safe, but what happens in other countries when big animals come into cities?In Cape Town, South Africa, baboons (狒狒) enter the city when they are hungry. They go into gardens and eat fruit from trees, or into houses and take food from cupboards (碗橱) and fridges. Baboons are strong animals and they can scare people. But the city can be dangerous for baboons too.Sometimes, they are killed in traffic accidents. Human food is very bad for their teeth because it has a lot of sugar. Now, there are baboon monitors (监督员) working in Cape Town to return the animals to the countryside.In Berlin, pigs sometimes come into the city to look for food.They eat flowers and plants from parks and gardens, and cause accidents in the streets. Some people like the pigs and they give them food and water to drink. Other people do not and want the government and police to stop them.In Moscow there are 35,000 wild dogs. They live in parks, old houses, markets and train stations. Many people give them food and water. Some make small houses for the dogs in their gardens. This helps them in winter, when the temperature is -10 C and there is a lot of snow and ice.In some cities, you can see birds, insects, mice and squirrels (松鼠) every day. But sometimes, it is dangerous when big animals come from the countryside to find food. We need some good ideas to stop animals coming into the city without hurting them.21. Why should we stop animals from entering cities?A. They often kill people in the streets.B. They eat too much food in people’s gardens.C. They may harm other animals in the city.D. They may cause trouble and endanger people’s lives.22. How are baboons treated in Cape Town?A. They are sent to the city zoo.B. They are taken back to the wild.C. They are fed with special food.D. They are provided with houses in parks.23. What can we learn from Paragraphs 4 and 5?A. Pigs are always well treated in Berlin.B. Wild dogs cause many problems in Moscow.C. People are friendlier to dogs than they are to pigs.D. Many people take care of wild animals in cities.24. What’s the article mainly about?A. Problems caused by big animals in cities.B. How wild animals are treated in different cities.C. Living alongside wild animals in cities.D. How to keep big animals away from cities.BShe had a few surgeries (手术) over the years, and before each one she’d have my father move the stove (火炉) out from the wall so she could clean behind it. It would have been hard for her to relax in the hospital if she knew there were dust balls behind the stove.The entire house was tidy and organized – there was a place for everything andeverything was in its place.Mom would hang the sheets (床单) outside to dry rather than inside the house. And if storm clouds gathered, she would run outside, race down to the sheets, throw them into a bag, and then race back to the house as the rain started, satisfied that a major catastrophe had been avoided.Throughout our entire childhoods, my sisters and I were spoiled with fresh bedding and cookies fresh from the oven.There’s something beautiful about freshness, like the beginning of a school year, the start of a marriage, the birth of a child, moving to a new place, or starting a new job.Freshness is like opening a new calendar that isn’t yet filled with neglect ed (被忽视的) tasks.A new year always means a chance at a fresh start. But the question is, how do we choose to make this new start?Maybe I need to do some housekeeping myself. A good sweeping usually leads to finding some interesting things – an old memory or two and new hobbies that fell by the wayside.Perhaps it’s time to clean out all those drawers (抽屉) filledwith junk –the ones holding old tapes that replay (重放) the things I regret doing and the things that I wish I had done.My personality could use some polish (亮光剂) as well – the ability to listen more than I talk. Glass cleaner (玻璃清洁剂) would be a good idea too – something to give me a clearer view of the things that matter and the things that don’t.Clea ning is rarely my first choice of activity, but I’m ready to go and do what needs to be done.Here’s to a fresh start and a new y ear.25. What can we learn about the author’s mother according to the article?A. She preferred rainy days to sunny days.B. She couldn’t bear anything to be unorganized in her house.C. She required her daughters to wash their own bedding.。

AWorlds of FunLocation: Worlds of Fun is located off Highway 435 in Kansas City, Missouri.History: Worlds of Fun was opened on May 26, 1973, at a cost of 25 million dollars. Loosely themed around the Jules Verne book, Around the World in Eighty Days, the park was founded by Hunt Midwest Company. In 1982, Hunt Midwest bought a nearby waterpark, Oceans of Fun. In 2013, Worlds of Fun and Oceans of Fun were combined to a one ticket admission, providing all guests with access to 235 acres of amusement and water rides.Hours: Worlds of Fun is open from April through Halloween.Tickets: Buy and print online. Always try to buy your tickets in advance, to save time when you get to the park.Reservations: Worlds of Fun sells “Fast Lane” cards that save riders’ time by allowing them to bypass the majority of wait for most of rides and attractions including Mamba, Prowler, and Patriot. Ride as many times as you want all day long.Strategy: Most visitors tend to begin the day with Prowler, the hottest attraction in the park. Use that tendency to your advantage and head to the Patriot first. After that, try the Dragons. Then work your way back to the Prowler. After riding the Prowler, there is only one coaster left, Mamba. Hit it next. If the park is not very crowded, you can ride Boomerang on the way to Mamba. After riding Mamba, head back for a ride on the Wolf. By then you will have tried most of the popular ride s and attractions in the shortest possible time.News: In 2017, Worlds of Fun is adding Steel Hawk, a ride that will take guests up 301 feet in the air and spin them at a 45-degree angle for a 60-second flight. Wait to have a try!21. When did Hunt Midwest’s two parks start to share one ticket?A. In 1937B. In 1982C. In 2013D. In 201422. With a “Fast Lane” card, the visitor can _________.A. save some moneyB. avoid lining up for longC. buy tickets onlineD. enjoy all the rides for free23. What is talked about in the part of Strategy?A. The hottest attractions in the park.B. The highest ride in the park.C. The best visiting route.D. The most popular tour season.24. According to the passage, by beginning with______ a visitor can try most of thepopular rides and attractions in the shortest possible time.A. ProwlerB. DragonsC. WolfD. PatriotBMy mom takes pride in the fact that I was talking in thr ee and four word sentences before I was ten months old. Some say it’s a gift while others simply think I talk too much. my thirties came to a close, I found myself reflecting on my life. I’m very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn’t seem to know when to stop talking. Whether it was hurting someone’s feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.To ta ke this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing ina conversation? He’s highly intelligent and has wonderful opinions but he’ll sit quietly and just listen. Even when he’s asked a pointed question, he’ll answer with few words while still communicating effectively. What a talent!Can you imagine be ing happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn’t feel confident enough to speak up, or they just didn’t feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.The first one didn’t work for me. I’m just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn’t work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it’s so strong that it causes me to behave badly in the form of interruptin g or speaking in an unusually loud voice.I had to look further.An interesting thing happened on this journey to the power of quiet. D uring my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I’ve found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.25. In Paragrap2 the writer mentions her husband mainly ______.A. to show how one communicates effectivelyB. to explain the reason for his silence in a conversationC. to give an example of those who have the power of quietD. to give her high opinion of his communication skills26. By “I had to look further”, the writer means she had to ______.A. look into the future in order to succeed in practicing the power of quietB. try harder to prevent herself from talking too muchC. survey people in other areas who talk littleD. find out other reasons why she should talk less27. Which of the following best describe the writer’s character?A. Kind but pessimistic.B. Loving and active.C. Selfless but proud.D. Stubborn and sensitive.CDuring my high school years, the most important thing was what I was wearin g to the Friday night dance and who I was taking. Although college was talked about, it was the least of my worries.When I was graduating eighth grade and starting high school, my older brother was graduating twelfth grade and going onto college. For my graduation, he gave me a card in which he wrote, “Enjoy your four years…, they go by fast.” I remember not believing him then, but looking back…, he was right. Those four years shaped who I was as a person, pushed me to my limit and encouraged me to become an adult.However, I was so completely absorbed in my junior and senior years of high school, that when someone spoke of college I brushed it off. I wasn't ready to leave my comfort zone of having all of my closest friends together and knowing what every single day was going to be like . Studying was something I did only AFTER I nailed my half-time dance performance. I knew my parents wanted me to go to college, so I told them I would go to community college and I didn’t worr y about my SAT scores.When my senior year passed and everyone graduated and went off to their own college ,I started to wish I had done the same. My friends were living away, meeting new people, discovering new places, and I was living at home and driving to and from class every day. It seemed exactly like high school. I hated it! I thought collegewas supposed to be different! Why didn’t I take more time to research colleges and do the same? I ended up loving college and wishing I had four years to enjoy the campus atmosphere instead of two.My advice to anyone thinking about attending college is to think about it very seriously and look into all of your choices well ahead of time. Now I have graduated and I am working full time and I would do anything to go back to my high school days for a second chance!28.Why didn’t the author worry about his SAT scores?A.He had a gift for dance.B.He believed his brother would help him.C.He was well prepared for the exam.D.He wanted to go to community college29.When in high school, the author __________________ .A.buried himself in his study all the timeB.drove to and from class every dayC.enjoyed talking about future college lifeD.lived in the school except on holidays30.What did the author’s brother mean by “Enjoy your four years…, they go by fast.”?A.He encouraged the author to leave his comfort zone.B.He advised the author to value the years.C.He wished the author to have more dance.D.He suggested the author aim at a community college.31.Talking of his high school years, the author feels .A.regretful B.Lonely C.angry D.pleasedDThe new two-child policy is making job hunting more difficult for women when about 40 percent of them said they were asked whether they planned to have a second childduring job interviews, according to a report in Chongqing.China dropped its decades-long one-child policy in October and allowed each family to have two children. The country now has about 270 million married women of childbearing age.This change has put millions of career women in a dilemma between family and career. Employers also face big challenges as more female workers will have two childbearing leaves, seven to eight months altogether.A human resources website conducted a survey among 500 employers and 5,000 job seekers about how the two-child policy affects the job market.Though two thirds of employers said the policy would make no difference to their recruitment(招聘), the survey showed that more than 70 percent of job seekers believe that bearing a second child will make women less popular in the job market. Forty percent of employers said they will give priority to married women with two children, according to the survey.Lin Xia, 29, quit her job after giving birth to her first child. She is now preparing to return to work. After several inquiries at a job fair, she found that the employers are concerned about future birth plans. "I thought it would be easier to find a job after giving birth," she was quoted as saying by the website. "I had to answer whether I will have a second child before I could get a chance for a job interview."Liang Siqi, 23, a college graduate, said although employers did not ask her the child question yet, she will not plan to have two children. "It (having two children) will definitely affect my career and personal life, so I will have only one," she said.Zhou Jiansong, who is in charge of human resources at a large private high-tech group in Chongqing, said the company will discuss birth issues with interviewees in order to make a better work plans. "We fully respect a women's right to bear a child or two," he said. "But you don't want them to go on a childbearing leave soon after they join your company." The experts expect more labor dispute cases concerning childbearing leave rights when bearing a second child in future.32. As for the influence of the new policy on working women, which of the following is TRUE?A. They will find it more difficult to ask for a leave in a company.B. Most of them will be force d to choose to have two children.C. Those who have two children may find it easier to get a job.D. Many of them will stay at home instead of working outside.33. In the opinion of Zhou Jiansong, what will employers probably do when interviewing women interviewees?A. They will pay no attention to women’s right to have a child or two.B. They will let women interviewees make a future plan.C. They may expect more labor debate cases about interviewees’ second-child plan.D. They may hope to know more about women interviewees’ childbearing plan.34. What can we infer from the report in the passage?A. All the women surveyed in the passage are married.B. Bearing a second child affects the women’s care er to some degree.C. About 70 percent of the women were asked whether they planned to have a second child.D. The women bearing a second child get the same chance as before to get a job.35. What is the writer’s attitude towards the new two-child policy?A. PositiveB. CriticalC. IndifferentD. Neutral第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

We started small. We knew we wanted to do something to make a difference.” The amount jumped to $80,000 the following year after the girls teamed up with friends, and the playground was built in 2013. It inspired Kaitlin to found Kids on a Mission, a kid-powered nonprofit organization that has helped hundreds of people living in poverty in the US and abroad.The work overseas started when Kaitlin, then 13, visited El Salvador in Central America. There, she saw people starving (挨饿) and families living in shelters made of cardboard (纸板).“The rooms were smaller than my bedroom, but there would be eight people living in [each one],” Kaitlin recalled. “We also got to see the rivers that these people were drinking out of, and [they contained] dirty water.”Providing clean drinking water for people living in poverty is now a focus (焦点) for Kids on a Mission. Children and adult volunteers dig wells (井) and also help orphans (孤儿) by providing food and clothes.“Being able to see how much they are suffering but then to give them food –that’s life-changing for us,” Kaitlin said.Kids on a Mission is in the process of giving children larger leadership roles within the organization now that Kaitlin is a junior in high school. She may not play as big of a role in the organization if she moves away for college.“This young lady just understands that by giving and having a huge heart, she’s not only changing the hearts of people in this community, she’s changing the world,” said Jim Yovino, Fresno County Superintendent of Schools.24.

Kaitlin succeeded in raising enough money fo r a playground with other people’s help.C. It took Kaitlin and her sister two years to raise $80,000 for Rescue the Children.D. Kaitlin started volunteering at Rescue the Children when she was 8 years old.25. What can we learn about Kids on a Mission?A. It was founded by Kaitlin and her sister in 2013.B.

So how do young people manage to express their individual (个人的) style? We interviewed some Brits in different parts of the country.“Young creative people in the UK have always come up with ways to express their individuality through clothes. Punks added zips (拉链) and safety pins , and skaters buy chains (链条) from hardware shops to hang from their trousers. You don’t need money –you need imagination,” said Alexi, art student, A ldershot.Printing your own T-shirt is the easiest and most common way to customise (定制) clothes. You don’t have to actually make a T-shirt. You can buy a cheap one and add an image (图像) of your choice.“I used to make customised, multicoloured T-shirts for my friends using fabric (织物) paints. They looked a bit messy but sort of cool. A couple of years ago, my mate Simon made one with a picture of Obama dressed as Che Guevara. He still wears it in fact. It looks great, said John, 25, Cheshire.Everyone kno ws that students don’t have a lot of money. That doesn’t have to be a problem if you’ve got a bit of imagination.“I used to make clothes sometimes when I was a student. Once I found a pair of trousers in a shop that I really liked, but I couldn’t afford t hem. I did a little sketch (素描) in a notebook, bought some fabric in the same colour and copied the trousers using my mum’s sewing machine (缝纫机). I loved it when people didn’t believe I had made them myself,” said Corrine, 31, Dundee.Buying second-hand or “vintage (复古的)” clothes is a fashion option for many young Brits.“I like to make or adapt (改造) my own clothes because I know that they will fit and that they’ll look good. I buy stuff like jackets, trousers and dresses insecond-hand shops. You can be sure you will always have something original as well as cheap,” said Helen, 26, Nottingham.28.

Popular clothes among young Brits.D. How young Brits show their personality through clothes.DDo you always struggle to understand others’ feelings? Perhaps you should listen to your heart.According to a team of scientists at Anglia Ruskin University in the UK, people who are more aware of their own heartbeat are better at understanding others’ emotions. Researchers have long suspected (怀疑) that this ability is important for understanding others’ thoughts and feelings.To test this theory, the British team asked 72 volunteers to count their ownheartbeats without feeling a pulse (脉搏). This aimed to see how aware they were of the feelings inside their own bodies.Then, the volunteers were shown video clips of social interactions (互动), which tested their ability to read the minds of the characters.During the clips, they were asked questions that required an understanding of the emotions of a certain character –for example, “What is Sandra feeling?” In addition, they were asked questions that did not involve any emotions, such as “What is Michael thinking?” They were also asked non-social questions, like “What was the weather like that evening?”The results showed that those who had counted their heartbeats most accurately were better at answering questions relating to the characters’ emotions. However, there was no link between the ability to feel what’s going on inside your body and questions that did not involve any emotions.Punit Shah, lead author of the study, used an example to explain this: If your colleague Michael is rude toward Sandra in public, your body processes (处理) this by increasing your heart rate. This may make you feel anxious and allow you to understand that Sandra is embarrassed .“If you do not feel your heart rate increase, it may reduce your ability to understand that situation and respond (反应) appropriately,” Shah told The Telegraph. Researchers believed their findings mean it could be possible to make people more empathetic by training them to listen to their hearts.This also lends support to the argument that feelings are, at the very least, deeply rooted in physical sensations (感觉).32. What does the new study find?A. People are better at understanding others’ emotions than thoughts.B. People with quicker heartbeats are more sensitive to others’ feelings.C. The ability to feel your heartbeat is important for understanding others’ thoughts.D. Your ability to fe el others’ emotions is related to your ability to feel your own heartbeat.33. Which of the following statements is TRUE about the new study according to thearticle?A. The volunteers were asked to count their heartbeats while watching video clips.B. Researchers designed emotional, non-emotional and non-social questions.C. The volunteers were required to describe each other’s thoughts and feelings.D. Researchers trained the volunteers to listen to their hearts and observed them.34. The underlined word “empathetic” in the second-to-last paragraph probably means ______.A. willing to accept ideas that are different from your ownB. not influenced in any way by other people or thingsC. being able to understand others’ feelingsD. willing to help those in trouble35. What can be concluded from the last four paragraphs?A. We react to a situation more slowly when our heart rates increase.B. Physical sensations in our bodies are believed to cause emotional changes.C. Our ability to feel emotions is part of us and can’t be changed.D. How we feel has nothing to do with the state of our bodies.第二节(共 5 小题;每小题 2 分,满分 10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
