She copied their actions and way of life - eating plants and getting down on her hands and knees to walk the way a gorilla does. It was a new relationship.Diane Fossey was murdered in Rwanda in 1985 and her story was made into the popular film Gorillas in the Mist. It was a long way from King Kong, which is about a gorilla as a monster (a frightening animal), and helped to show a new idea: the real monster is man, while the gorillais to be admired.Today there are thought to be around 48,000 lowland gorillas and maybe 400-450 mountain gorillas in the wild. From the Congo in West Africa, to Rwanda and Uganda further east, they are endangered by hunting and by the cutting down of their forest homes.Some time ago, I found in my letterbox a little magazine from the World Wide Fund for Nature. It had two photos side by side. One was of a young gorilla. “This is a species(物种)of mammal (哺乳类动物),” said the words below it. “It is being destroyed by man. We must save it for our own good.” The other photo showed a human baby. The words also read, “This is a species of mammal,” but then went on: “It is the most destructive(破坏性的) on earth. We must retrain(教育)it for its own good.”1. The text mainly talks about _____.A. Diane FosseyB. the gorillas in RwandaC. the protection of the gorillasD. the film Gorillas in the Mist2. According to the text, the two countries Rwanda and Uganda are _____.A. in West AfricaB. in East AfricaC. in South AfricaD. in North Africa3. We can learn from the text that _____.A. Gorillas in the mist was based on(基于)Fossey’s experiencesB. Lowland gorillas live longer than mountain gorillasC. King Kong showed us that a gorilla is admirableD. Diane Fossey was murdered by a gorilla4. What message can we get from the two photos in the magazine?A. Gorillas are man’s close friends.B. Both man and the gorilla need to be saved.C. Young gorillas are as lovely as human babies.D. Man should live peacefully with the gorilla.【试题答案】I. 单项选择1. B2. D3. C4. C5. A6. C7. C8. D9. B 10. A 11. A 12. C 13. B 14.A 15. DII. 综合阅读1.

学年度人教版高一上学期必修一第一二单元测试

2011—2012学年度上学期单元测试高一语文试题(1)【新人教】命题范围:必修一第一、二单元第Ⅰ卷为阅读题,共70分;第Ⅱ卷为表达题,共80分。

满分150分,考试时间为150分钟。

第Ⅰ卷(阅读题,共70分)一、现代文阅读(9分,每小题3分)阅读下文,完成1—3题生物钟是一门跨学科科学。

生物钟学的中心概念是生物节律。

生物节律是一种十分奇特的机制。

它可以帮助生物体适应不断变化的情况。

每个器官和系统都有自己的节律,而它们之间又是互相衔接的。

譬如,心跳平均每分钟70次。

而晚上只有60至50次。

处于运动状态时,心跳则会加快。

呼吸和新陈代谢也如此。

为了适应不断变化的环境,自然界就产生了生物节律。

生物节律是自然界产生的生物现象。

它存在于生命的各个阶段。

研究表明,生物节律对肌体适应不良生态因素起着重要作用,同时影响到疾病的治疗和预防。

生物钟医学中还有一个概念——非同步。

它犹如钟表中的尺寸不同的齿轮。

当齿轮相吻合时,就会不停地运动。

当齿轮出现故障时,肌体就有了毛病。

坐飞机到外地就是一个例子。

人已经习惯于晚上呆在某个地方,如果换了地方,肌体就需适应变化。

如果不适应,人就会懒洋洋、工作效率低下、头疼、精神紧张;自我感觉不佳等。

这一切都可称作非同步。

一昼夜中,人体的机能是不断变化的,病亦如此,而且是严格遵循规律的。

就拿高血压来说,早晨血压会升高,白天会下降并趋于正常,夜间又会升高。

借助血压计可以测量出血压在一天中的变化情况。

人可以根据血压升降的规律服药,而不是死板地一日三次。

也就是说,一天服一次药就可以达到稳定血压的目的。

少服药可以减少药物对人体的副作用,又可省钱。

同样,针灸和理疗也要选择最佳时刻。

选择的时间不当,也许还会造成不良后果。

科学家曾经做过实验。

他们给家鼠注射了增加肌肉收缩力的药物。

药量相同,注射时间不同,结果大相径庭。

早上注射,家鼠几乎全军覆没,而晚上注射则无一死亡。

现代生物钟医学的主要研究课题是,研究纠正人体生物节律的方法和药剂。

It wasn’t the fir st time that I had been abroad. Like most English children, I learned French at school. I had often been to France, so I was used to speaking a foreign language to the people who didn’t understand English. But when I went to America, I was really looking forward to having a nice easy holiday without any language problems.How wrong I was! The misunderstandings (误解) began at the airport. I was looking for a public telephone to give my American friend Jenny a call andtell her that I had arrived. A friendly old man asked me if he could help me.“Yes,” I said, “I want to give my friend a ring.”“Well, that’s nice,” he said. “Are you getting married?”“Who is talking about marriage?” I replied. “I only want to give my friend a ring to tell her I’ve arrived. Ca n you tell me where there’s a phone box?”“Oh!” he said, “there’s a phone downstairs.”When at last we met, Jenny explained the misunderstandings to me.“Don’t worry,” she said to me. “I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You’ll soon get used to all the funny things they say.

He always traveled with his driver, Harry, who would go to each of these lectures while seated in the back row!One day, after Einstein had finished a lecture and was coming out of the lecture hall into his car, Harry said, “Professor Einstein, I’ve heard your lecture so many times. If I were ever given a chance, I would be able to give a lecture myself!”“Very well,” replied Einstein, “I’m going to Dartmouth College next week. They don’t know me. You can give the lecture as Einstein, and I’ll be Harry!”So Harry gave the lecture in Dartmouth College the next week while Einstein sat in the back row playing “driver” as Harry did before and having a short sleep. And people found nothing wrong about the lecture.Just as Harry was walking down from the podium (讲台), however, one of the listeners asked him a question about the theory on relativity (相对论). That was a difficult one. Harry replied to the listener, “The answer to this question is very simple! In fact, it’s so simple that I’m going to let my driver answer it!”43.

Girls on the Run uses running to encourage girls from 8 to 13 to stay in physical shape. The group also holds after-school activities where girls learn good behavior.Nine-year-old Ela Kalra joined Girls on the Run at Washington International School. “It’s really fun and it teaches you how you should care for others and what you should think about yourself,” Kalra said. “You shouldn’t be unkind to anybody else.” Ela is among 60,000 girls in 45 states who have joined the 10-week program. They also learn about nutrition and how to be confident.Molly Barker, a runner, founded (成立) Girls on the Run in the southern state of North Carolina. She says the girls discuss what she calls “the girl box”, society’s definition(定义) of how girls should look, act and feel. “There’s acertain appearance a girl should have; there’s a certain way a girl should act,” Barker said. “But the girls should learn that instead of trying to fit into it, they should be themselves. The girls discuss developing good behavior, such as caring about others, and avoiding negative behavior like using their strength or power to frighten or hurt someone who is weaker.”Each group carries out a service project. The girls at Washington International School are running and taking donations for a Washington-based group, Girls Gotta Run Foundation. The money is used to buy shoes for girls in Ethiopia who are training to be professional runners. And it also helps keep them in school.47. Who will be most likely to take part in Girls on the Run?A.

On Monday she gave each student the list.Before long, the students were smiling. “I never knew that I meant anything to anyone! And I didn’t know others liked me so much,” most students said. No one ever mentioned anything about the paper in class again, but it didn’t matter. The students were happy with themselves and one another. That group of students moved on.Several years later, one of the students, Mike, would graduate from Harvard University and this teacher and some former classmates attended the commencement (毕业典礼).Mike came up to her. “I want to show you something,” he said, taking a wallet out of his pocket.

Charlie said, “Mine is in the top drawer of my desk.” Chuck said, “I put mine in my album.” “I think we all treasured our lists,” Marilyn said.Tears rolled down the eyes of the teacher.

It will also be a great idea to practice speaking and writing in business English. If a university offers a course on business English, it will be a good idea to take the class. Reading, writing and speaking English is necessary to start a business.Business English is different from asking where to find the nearest hotel. There are classes you can take to help you but there are things that you can learn on your own. Vocabulary and grammar are a good place to start with. Youneed to know what words mean. Later, try to pronounce the words and then look them up in the dictionary. Try using them in a sentence and ask someone who is good at English to help you. Once you have an understanding of English, you can use it in business English.In business you will have to learn such things as taking messages, answering the phones withproper words and communicating with your co-workers. You may have to learn how to make travel plans. Business English is very different than spoken English. Grammar is the same but you have to learn things like expressing yourself in a proper manner or maybe making a report in your office.If you are working in the customer service sector (客户服务部门), you really have to learn business English. Dealing with the public is sometimes more important than asking your boss for a raise (加薪). Most businesses offer training classes and some companies offer classes on how to do the job with proper business English.40. Why do people learn business English?A. They want successful communication.B. They want to ask the boss for a raise.C. They want to have their own company.D. They will have a chance to get a better job.41. We can learn from the text that business English ______.A. is much more difficult than daily EnglishB. pays more attention to the forms of expressionsC. is required by most international companiesD. can give you a hand when dealing with people42. What’s the text mainly about?A. The development of business English.B. The tips on learning business English.C. The introduction to business English.D. The comparison between business English and daily English.43. The following language skills are mentioned of business English EXCEPT ______.A. listeningB. readingC. speakingD. writing44. Which of the following is TRUE about the first three parks?A. They all have rich wildlife.B. They all have restaurants nearby.C. They all provide a place for children.D. They all provide a quiet place for relaxing.45. What is special about Battersea Park?A. You can enjoy boating there.B. You can listen to different concerts.C. You can visit the special stone wall.D. You can have a bungee jump there.46. In what way is London Park different from the other ones?A. It offers theatre performances.B. It provides a grass area for sports.C. It provides an art museum visit.D. It offers all kinds of outdoor activities.47. If you want to meet film stars, you will probably choose ______.A. London ParkB. Battersea ParkC. Greenwich ParkD. London Victoria Tower GardensDHave you ever noticed something — like the ants in your backyard, or smoke from a forest fire, or the moon at night —and thought to yourself, “I wonder ...”These two words can lead to a science journey and they recently brought 30 middle school students to Washington, D.C. There, they spent four days joining in scientific challenges. One of the challenges was figuring out how the flu(流感) might spread from person to person. The judges(审判官) would have an interview with each student. Students were judged on their scientific knowledge, ability to understand new ideas and scientific thinking. They were also judged on their teamwork (合作), leadership andcommunication skills.Finally, five of the students won top prizes, and were announced as the winners of the 2008 SSP Middle School Program in Washington, D.C. on October 21st. Christopher Sauer was one of the five students.Christopher Sauer, 13, won first place, a $20,000 scholarship. He was chosen to attend a science project team that builds a special engine. Christopher and his friend came up with the idea after watching a movie about submarines (潜水艇) that use this kind of engine.So the next time you find yourself saying “I wonder ...”, spend some time thinking about how you might explore your idea further. You never know where your interest might lead you —perhaps to Washington, D.C.!48. These two words “I wonder” in your mind can ______.A. start a science project right awayB. make you begin a science journeyC. help solve the problems you meet withD. stop you from finding an unknown world49. How many students succeeded in the scientific challenges?A. Five.B. Thirty.C. Four.D. One.50. According to the text, which of the following is TRUE about Christopher Sauer?A. He wanted to attend a science project team.B. He had that idea after watching a movie.C. He sold his invention for $20,000.D. He invented a special submarine.51. What would be the best title of the text?A. Christopher Sauer’s dreamsB. Beautiful views in Washington, D.C.C. Middle school science adventuresD. Research on the ants in your backyardEThere are many reasons why people work from home. One of the largest groups of people who work from home are stay-at-home moms and dads. For parents, working from home allows them to be home for their families while meeting their financial goals (经济目标). This is a good example of why people work from home.Flexibility (灵活性) is another reason why people work from home. It means that if you need to, you can take two days off in the middle of the week and then work in the evenings or on the weekend. For the most part people work from home because they are free to choose when and how they work. This flexibility allows people who work from home to fit other things into their lives that they might not have time for in traditional working time.The question of why people work from home isn’t always answered by the flexibility working from home provides you. Many people start their businesses from home in order to save start-up costs, such as leasing an office. Others work from home because their business takes place within their home. Daycares and small businesses such as hair salons or art studios are examples of this. Some jobs take place outside the traditional office space because the type of work. If someone’s business is building furniture for example,working from home makes more sense than trying to find a place that satisfies (满足) these same needs.With so many businesses and so many different business needs, there are many reasons why people work from home.52. The advantages of people working from home DON’T include ______.A. the flexible working timeB. saving business costsC. staying with their familiesD. making more money53. How does the author express his opinion in paragraph 3?A. By doing a research.B. By comparing the results.C. By giving the examples.D. By describing his experience.54. What is the meaning of the underlined word “leasing”?A. Paying money to use a room.B. Choosing a suitable place.C. Building a room with others’ help.D. Sharing a place with somebody.55. What is the main idea of the text?A. It is convenient and popular to work from home nowadays.B. Different people have different reasons to work from home.C. Flexibility is the main reason why most people work from home.D. Working from home encourages the development of small businesses.四、写作(共两节,满分35分)第一节短文改错(共10小题;每小题1分,满分10分)第二节书面表达(满分25分)你所在的班级正举行英语作文比赛,主题是:How to improve your English?请你写一篇文章参加比赛,参考要点如下:1. 尽量多练习说英语;2. 努力用英语来思考;3. 多读英语文章;4. 学习和了解更多关于语言背后的文化知识。
