ASteven Jobs,the designer of Apple Computer,was not clever when he was in school.At that time,he was not a good student and he always made troubles with his schoolmates.When he went into college,he didn't change a lot. Then he dropped out（退学）.But he was full of new ideas.After he left college,Steven Jobs worked as a video game designer.He worked there for only several months and then he went to India.He hoped that the trip would give him some new ideas and give him a change in his life.Steven Jobs lived on a farm in California for a year after he returned from India.In 1975,he began to make a new type of computer.He designed the Apple Computer with his friend in his garage.He chose the name "Apple" just because it could help him to remember a happy summer he once spent in an apple tree garden. .His Apple Computer was so successful that Steven Jobs soon became famous all over the world.He often said,"I live in order to change the world;there aren't any other reasons.The only way to have a great achievement is to love your own career.If you can't find your favorite career,go on looking for it and never give up."This is Steven Jobs.Though he is dead,his spirit and achievements still influence our lives.1.Why was Steven Jobs not a good student in school?A.

His saying.BAlthough English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from.Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Ger mans did not understand the question and answered. “We came from Hamburger.” One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburger ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called “ hamburgers”. Today “hamburgers” are sold in many countries around the world.Whether this story is true or not, it is certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason, for most English words, can be found in any large English dictionary.4．According to the writer, English is .A. as old as ChineseB. older than GermanC. not so old as ChineseD. very difficult to learn5．We know from the story that .A. few Americans like hamburgersB. hamburgers were made by GermansC. hamburgers are made with hamD. hamburgers were sold all over the world about a century ago6．According to the story, the word “hamburger” comes from.A.

In fact, some people say the word“OK”means all right or acceptable; it expresses agreement or approval.11．Some people say it came from the Native American Indian tribe known as the Choctaw. The Choctaw word “oken”means the same as the American word“okay”. Experts say early explorers in the American West spoke the Choctaw language in the 19th century.But many people doubt this. Language expert Allen Walker Read wrote about the word“OK”in reports published in the 1960s. He said the word began being used in the 1830s.12．Some foreign-b orn people wrote“all correct”as“oll korrect”，and used the letters OK. Other people say a railroad worker named Obadiah Kelly invented the word long ago. They said he put the first letters of his names—O and K—on each object people gave him to send on the train.13．The organization supported Martin Van Buren for president in 1840. They called their group the OK Club. The letters were taken from the name of the town where Martin Van Buren was born－Old Kinderhook, New York.Then there is the expression A-OK. It is a space-age expression. It was used in 1961 during the flight of astronaut Alan Shepard. He was the first American to be launched into space. His flight ended when his spacecraft landed in the ocean, as planned. Shepard reported，“Everything is AOK.”14．One story says it was first used during the early days of the telephone to tell an operator that a message had been received.There are also funny ways to say okay. 15．These expressions were first used in the 1930s. Today, a character on the American television series, “The Simpsons”，says it another way. He says okely-dokely.A. Some people say okey-dokey or okey-doke.B. Still others say a political organization invented the word.C. Therefore, it has become popular in that area from then on.D. But many experts don't agree on what the expression means.E. Language experts do not agree about where the word came from.F. It was a short way of writing a different spelling of the words“all correct”．G. However, some experts say the expression did not begin with the space age.二、完形填空(共20小题；每小题1.5分，满分30分)阅读下面短文，各题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题纸上将该选项标号涂黑。

Our door in the inner city is constantly knocked on; our previous door in the suburbs rarely so. Sam has a full-time job and cannot spend his days answering requests to fix leaking baths or carry cash to the bank.Sam opened the door and it was Mervin."There's a bird on the second floor, " he said. "Ifs in trouble."Sam followed Mervin upstairs. Mervin pointed and turned to let Sam look. It was a pigeon, the most common of all birds, the bird most likely to foul （弄脏）your newly washed car. And it wasn't flying away. It was stamping in circles. As Sam bent to look, Mervin coughed, "Number two."Sam asked him to repeat that. "Number two, " Mervin said. "The pigeon has been sitting in his own number two, and now it's stuck to his foot."It had rained for five days, and the bird was young. It could have been sheltering in a wet nest of its own waste, which had then dried on its foot, preventing it from flying away. The pigeon moved in a few more circles. Sam bent to take another look. Mervin said, "All right, then." and walked away."Why does everyone think you must solve the problems around here?" I said to Sam when he returned with his story. "It's a bird. Just leave it on the stairs, and let nature take its course." Sam didn't agree. Then he went to the garage and emptied the cardboard box containing our imported camping mats. He returned with the gray pigeon in the box. He showed the bird to our children and they decided to keep it.They put its foot in the warm water bath and got rid of its waste. Immediately the pigeon erupted in a bomb of feathers and began flying.4.How did the author feel about the knocks?A.She felt bored.B.She was frightened.C.She got excited.D.She was surprised.5.Why was the pigeon moving in circles?A.It was learning to fly.B.It was badly injured.C.It got caught in the rain.D.It was trapped by its waste.6.What did Sam use the cardboard box to do?A.Shelter from rain.B.Give it to Mervin.C.Wash camping mats.D.Make a nest for the bird.7.What can we learn about Sam from the text?A.He was brave.B.He was clever.C.He was warm-hearted.D.He was easy-going.CThe impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude.When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself? Your abilities? Your interest in the job?Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain: "I'm sorry, but I didn't catch that.""I'm not sure exactly what you mean."Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.At the end of the interview, thank the interviewer for her or his time.It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.Good luck!8.

Why should we pay attention to our body language?A.Because it can help us win the employer's positive impression.B.Because it can help us feel about the employer.C.Because it is needed by our employer.D.Because we need it to improve our feelings.10.The main purpose of the passage isA.to give you some advice on the art of finding a jobB.to tell right from wrong about job interviewsC.to explain why we should do something about an interviewD.to suggest not being shy in an interview11.Which of the following can be the best title for the passage?A.Friendly SmileB.Making a Good ImpressionC.Don't Be NervousD.Sending a Than-You LetterDMany people believe eating healthily is expensive — and more costly than buying junk foods. But our new research, published in the BMC Public Health, shows this isn't the truth.Most of the Australian family food budget （(预算)）is being spent on junk foods and drinks that are high in fat, sugar and salt.Less than 7% of Australians eat healthily. The Australian adults get at least 35% of their energy from junk foods and drinks. As a result, two-thirds of adults （63%）and one-quarter of children are overweight.We used the Australian Health Survey 2011-2013 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high- and low-socioeconomic （（社会经济地位低的）areas in Brisbane, and compared the diet prices with family incomes.In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods （14%）, and sugary drinks （4%）.In the low-socioeconomic area, a family of two adults and two children spend $640.20 every two weeks on their present diets, but could buy a healthy diet for $560.93 every two weeks. In the high-socioeconomic area, these numbers are $661.92 and $580.01.Supermarket food prices were about 3% higher in the high-socioeconomic location. Takeaway foods were also relatively more expensive, but sugary drinks were priced similarly in both areas.Present diets cost more than healthy diets, so causes other than price must be helping to drive preferences for unhealthy choices.12. What did the researchers find?A.Australians have a preference for sweet foods.B.Most Australian kids have fat problems.C.Half Australians live on junk foods.D.Most Australians eat unhealthily.13. How did the researchers get the result?A.By making a comparison.B.By doing the study online.C.By carrying out interviews.D.By asking personal questions.14. What can we learn from Paragraph 5?A.Australian foods are healthier.B.A healthy diet is actually cheaper.C.Health foods are becoming more expensive.D.People choose junk foods for their low prices.15. What might a following paragraph be about?A.The harm of junk foods.B.How we can eat healthily.C.Why people choose junk foods.D.The advantages of a healthy diet.第二部分：英语知识运用（共两节，满分35分）第一节完形填空（共20小题；每小题1分，满分20分）阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。

一、选择题。

（54分）1.周灭商之后，推行分封制，如封武王弟康叔于卫，都朝歌（今河南淇县）；封周公长子伯禽于鲁，都奄（今山东曲阜）；封召公奭于燕，都蓟（今北京）。

上述材料表明分封制A. 加强周天子对地方的直接控制B. 进一步扩大周王室统治区域C. 形成了等级森严的统治体系D. 有利于血缘政治的稳定【答案】B【解析】【详解】周天子通过分封诸侯对地方实行间接控制，A错误；为了巩固被征服的广大地区，西周通过分封制拓展了西周的统治区域，巩固了西周的统治，故B正确；材料中没有体现出等级制度，排除C；宗法制有利于血缘政治的稳定，排除D。

2.秦始皇规定，全国政务系统下的主要官员全由皇帝任命，收入按等级进行分拨。

这种做法A. 是对分封制的延续B. 起到了监察百官的作用C. 是对嫡长子继承制的发展D. 有利于中央对地方的管理【答案】D【解析】【详解】材料反映的是秦朝推行郡县制，它是对分封制的否定，排除A；材料没有反映秦朝的政务系统下的主要官员的职权，排除B；据题干“全国政务系统下的主要官员全由皇帝任命”可知，官员由皇帝任命，而非沿袭商周的血缘政治，有利于中央对地方的管理，故排除C，选D。

3.下列历代措施中，起到限制地方割据势力作用的是①汉武帝颁行“推恩令”②唐朝设置节度使③宋太祖派文臣任地方长官④元在地方设“行中书省”A. ①②③④B. ①②③C. ①②④D. ①③④【答案】D【解析】【详解】依据所学可知，汉武帝颁行“推恩令”使得诸侯王国势力越分越小，削弱了地方割据力量，加强了中央集权，①符合题意，正确；唐朝设置节度使，节度使拥有地方军政大权，节度使的设立加剧了地方割据，不利于中央集权，②不符合题意，错误；宋太祖派文臣担任地方长官，主要是为了防范武将专掌军权、独霸一方、反叛朝廷，起到了限制地方割据势力的作用，③符合题意，正确；元在地方设立“行中书省”，作为中书省的派出机构，行使权力受到中央节制，起到了限制地方割据势力的作用，④符合题意，正确。

一、阅读理解（共20小题，每小题1.5分，满分30分）AFriend is better than fortune. A friend is worse than poison in some cases. The two sentences above have opposite meanings and seem to be unreasonable, but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us into bad ways.My ideal friend is of course a good friend whose goodness is shown below — he has no bad habits, such as smoking and drinking. He lives in frugality (节俭) He studies hard so as not to waste his golden time.

I hurried to my science class in the morning and found a seat in the back. I waited there for 15 minutes before the bell rang. The science teacher told us about some class rules. Noone talked to me nor did I talk to anyone else. I was one ofthose very shy girls. After the science class, I had an English class. I thought it would be boring but it turned out to be very funny. When the classes of the morning ended I went to lunch. I sat outside the dining room with no one to talk to and no food because I was too nervous to join the lunch line. I kept looking around hoping to see someone I knew but I never saw anyone.Lunch ended and I went to have my art class. I was the first one there and not even my teacher was there yet. So I sat at my desk and started drawing some pictures. I didn't notice the rest of the class walking in or the girl that was standing behind me till I was surprised by the voice, “So what are you drawing？”It was a girl who had really long hair. She ended up being my best friendand one of the kindest and liveliest girls I know.In the next class meeting, the teacher asked us to talk aboutthe past holiday.

Help please.”I had nothing on me, so I did my shopping and just hoped he would stay there by the time I finished what needed to do.I did my shopping quickly and bought him some chocolate and prepared a bank note for him. When I left the shop, he was still there so I started a little conversation. He said he was from Glasgow, Britain, and that he was homeless here without any relatives or friends. My heart went to him. No one should be homeless. We should all have the right to own a shelter in some shape of form. I gave him the chocolate and some money and when he looked at the bank note, he said, “Are you sure?” I said, “Yes, it is your birthday gift.”Moved deeply, he said, “You know it is really my birthday, I was born on the 16th of August 1970, and this is the best present I have received today. “In my heartI knew that he was telling the truth despite just a few words written carelessly ona piece of cardboard. These are things one just knows in their heart. While I am writing this story, I realize that my brother was born in 1970. He could be my brother. He probably is someone’s brother. My wish for him is that he gets his life organized and finds a place he can call home.12．Why didn't the author help the homeless man when she first saw h im？A．She had no time to offer help． B．She had nothing to give him．C．She didn't notice the sign． D．She didn't know about him．13．What did the author do in the shop besides shopping？A．She waited until the man left． B．She enjoyed all kinds of go ods．C．She relaxed herself in the shop． D．She prepared a bank note for the man．14．We can know from the last paragraph that．A．the man told a lie about his birthdayB．the author disliked the hand writingC．the author didn't doubt the man's wordsD．the man was the author's brother15．What did the author wish the man to do in the future？A．To get married． B．To live with relatives．C．To live a normal life． D．To return home．EAdvice to English learnersLearners of English, especially self-taught learners may have trouble in understanding speeches by native speakers. The following ways might help improve their ability.First of all, do things step by step. It is not good to listen to something beyond your level. Better choose a suitable course and start with the first book. Go on to the second book only after you are sure you understand the first one.Secondly, stick to one course of study. Don’t change books often. Never let your attention be attracted by another course just because it seems to be more“ fashionable”(时髦).Thirdly, listen to the English news programme over the radio from time to time. Better go through the news stories in the Chinese-language newspaper first. That will make it easy for you to understand the English news on the radio.Fourthly, if you have time, listen to some interesting stories in “special English” from the VOA or other listening materials of the same level as that of your textbook.16.This is a piece of advice to learners of English in how to_____.A．improve their listening ability B．read fastC．write better English and read fast D．speak correctly17. If you want to understand the English news programme on the radio, youshould_________.A .read the Chinese-language newspaper carefullyB.read again and again the Chinese-language newspaperC.go through the Chinese-language newspaperD.be able to recite the Chinese-language newspaper18.“Beyond your level” means something_______.A．easy for you B．too difficult for youC．not too easy and not too difficult for you D．just all right for you19..

Our door in the inner city is constantly knocked on; our previous door in the suburbs rarely so. Sam has a full-time job and cannot spend his days answering requests to fix leaking baths or carry cash to the bank.Sam opened the door and it was Mervin."There's a bird on the second floor, " he said. "Ifs in trouble."Sam followed Mervin upstairs. Mervin pointed and turned to let Sam look. It was a pigeon, the most common of all birds, the bird most likely to foul （弄脏）your newly washed car. And it wasn't flying away. It was stamping in circles. As Sam bent to look, Mervin coughed, "Number two."Sam asked him to repeat that. "Number two, " Mervin said. "The pigeon has been sitting in his own number two, and now it's stuck to his foot."It had rained for five days, and the bird was young. It could have been sheltering in a wet nest of its own waste, which had then dried on its foot, preventing it from flying away. The pigeon moved in a few more circles. Sam bent to take another look. Mervin said, "All right, then." and walked away."Why does everyone think you must solve the problems around here?" I said to Sam when he returned with his story. "It's a bird. Just leave it on the stairs, and let nature take its course." Sam didn't agree. Then he went to the garage and emptied the cardboard box containing our imported camping mats. He returned with the gray pigeon in the box. He showed the bird to our children and they decided to keep it.They put its foot in the warm water bath and got rid of its waste. Immediately the pigeon erupted in a bomb of feathers and began flying.4.How did the author feel about the knocks?A.She felt bored.B.She was frightened.C.She got excited.D.She was surprised.5.Why was the pigeon moving in circles?A.It was learning to fly.B.It was badly injured.C.It got caught in the rain.D.It was trapped by its waste.6.What did Sam use the cardboard box to do?A.Shelter from rain.B.Give it to Mervin.C.Wash camping mats.D.Make a nest for the bird.7.What can we learn about Sam from the text?A.He was brave.B.He was clever.C.He was warm-hearted.D.He was easy-going.CThe impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude.When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself? Your abilities? Your interest in the job?Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain: "I'm sorry, but I didn't catch that.""I'm not sure exactly what you mean."Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.At the end of the interview, thank the interviewer for her or his time.It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.Good luck!8. It can be learned from the passage thatA.you should always put on a smile when meeting the employerB.you should stand still with respect before the employerC.employers understand and like employees' nervousnessD.the first impression is very important in an interview9. Why should we pay attention to our body language?A.Because it can help us win the employer's positive impression.B.Because it can help us feel about the employer.C.Because it is needed by our employer.D.Because we need it to improve our feelings.10.The main purpose of the passage isA.to give you some advice on the art of finding a jobB.to tell right from wrong about job interviewsC.to explain why we should do something about an interviewD.to suggest not being shy in an interview11.Which of the following can be the best title for the passage?A.Friendly SmileB.Making a Good ImpressionC.Don't Be NervousD.Sending a Than-You LetterDMany people believe eating healthily is expensive — and more costly than buying junk foods. But our new research, published in the BMC Public Health, shows this isn't the truth.Most of the Australian family food budget （(预算)）is being spent on junk foods and drinks that are high in fat, sugar and salt.Less than 7% of Australians eat healthily. The Australian adults get at least 35% of their energy from junk foods and drinks. As a result, two-thirds of adults （63%）and one-quarter of children are overweight.We used the Australian Health Survey 2011-2013 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high- and low-socioeconomic （（社会经济地位低的）areas in Brisbane, and compared the diet prices with family incomes.In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods （14%）, and sugary drinks （4%）.In the low-socioeconomic area, a family of two adults and two children spend $640.20 every two weeks on their present diets, but could buy a healthy diet for $560.93 every two weeks. In the high-socioeconomic area, these numbers are $661.92 and $580.01.Supermarket food prices were about 3% higher in the high-socioeconomic location. Takeaway foods were also relatively more expensive, but sugary drinks were priced similarly in both areas.Present diets cost more than healthy diets, so causes other than price must be helping to drive preferences for unhealthy choices.12. What did the researchers find?A.Australians have a preference for sweet foods.B.Most Australian kids have fat problems.C.Half Australians live on junk foods.D.Most Australians eat unhealthily.13. How did the researchers get the result?A.By making a comparison.B.By doing the study online.C.By carrying out interviews.D.By asking personal questions.14. What can we learn from Paragraph 5?A.Australian foods are healthier.B.A healthy diet is actually cheaper.C.Health foods are becoming more expensive.D.People choose junk foods for their low prices.15. What might a following paragraph be about?A.The harm of junk foods.B.How we can eat healthily.C.Why people choose junk foods.D.The advantages of a healthy diet.第二部分：英语知识运用（共两节，满分35分）第一节完形填空（共20小题；每小题1分，满分20分）阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。
