第一节(共15小题;每小题2分,满分30分)

A

In my younger days I worked in a small factory. That’s where I first met Mike and Peter, who always made jokes. Jake, another colleague, was a little older than the rest of us — quiet, harmless. He always ate his lunch by himself and wore the same trousers for three years. He was a natural target for jokes, but he always took it in good humor. Then one fall, Mike and Peter took a few days off to go hunting. And they promised all of us that if they got anything they’d bring us each a piece. So we were all quite excited when we heard that they’d returned with a really nice big pig.

We heard more than that. Peter would play a joke on Jake. Mike had cut up the pig and made a nice package for each of us. And, for the joke of it, he had saved the ears and the tail — it would be so funny when Jake saw them.

Mike distributed his packages. We each got a nice piece, opened it, and thanked him. The biggest package of all he saved until last was for Jake. Like always, Jake sat alone on the far side of the big table. Mike pushed the package over to him. He took the package firmly and stood up, smiling broadly. “I knew you wouldn’t forget me,” he said. “I’ve got a wife who is sick and nine kids at home. And most of my money has had to go for doctors and med icine…”

Hearing that, Mike and Peter both dove to try to seize the package, but they were too late. Jake looked up and tried to smile, saying that he liked his present. Mike and Peter’s faces turned red.

36. Jake acted differently from other colleagues because he .

A. felt upset to have a sick wife home

B. had difficulty in raising his family

C. got annoyed at the colleagues’ jokes

D. was too shy to share his thoughts

37. Mike saved the ears and the tail to .

A. make fun of Jake

B. take pity on Jake

C. give Jake an extra share

D. help Jake out of trouble

38. How did Mike and Peter feel in the end?

A. Ashamed.

B. Puzzled.

C. Excited.

D. Pitiful.

39. What’s the main purpose of the text?

A. To tell us a humourous story.

B. To describe a common phenomenon in life.

C. To tell us how we should react to others’ jokes.

D. To tell us we should walk in another’s shoes first.

B

In George Bernard Shaw’s Pygmalion, the storyline centers around three main characters: Eliza Doolittle, Professor Henry Higgins, and Colonel Pickering. Eliza Doolittle is a flower girl who is under the instruction of Professor Higgins and Colonel Pickering to learn proper grammar and phonetics. Eliza can be characterized as a very sensitive and emotional person. She seeks to be treated like a duchess by men. Her personality clashes (冲突) with the personality of Professor Higgins in an extreme way. Professor Higgins is an arrogant (傲慢的), work-obsessed expert in phonetics who views Eliza simply as an experiment. He is a bachelor who has never found a place for women in his life due to his obsession (痴迷) with language. Colonel Pickering is a gentleman from India who is also an expert in language. He is gentler than Higgins and treats Eliza with respect while maintaining a professional interest in her similar to that of Higgins. These three make up the main action of the novel as Eliza learns speech of the upper class from them. She manages to pass herself off as a Hungarian princess at a formal party. This achievement gives credence(相信) to the efforts of Higgins and Pickering. After experiencing life in the upper class, Eliza settles for a lower class life with a man who loves her for what she is and wants to marry her. After some small and unimportant disputes, Eliza and Higgins remain friends in the time after. Other memorable characters include Mrs. Higgins who maintains an authoritative figure over her grown son and Mr. Doolittle who rises from a dustman to a well-respected speaker in the community.

I think that this is a good book because it shows that happiness can be achieved without wealth and fame. I highly recommend it due to its emphasis on grammatical and phonetic correctness, a dying art in this time period.

40. Eliza learns speech of the upper class because .

A. she wants to do an experiment

B. she wants to marry a gentleman

C. she has to play a princess at a party

D. she wants to be treated respectfully

41. Who treats Eliza Doolittle in a more respectful way?

A. Henry Higgins.

B. Colonel Pickering.

C. Mrs. Higgins.

D. Mr. Doolittle.

42. The author highly recommends Pygmalion because it can teach people .

A. the right way to use language

B. the right attitude towards life

C. the way to deal with different people

D. the determination to succeed

43. The text is probably from .

A. a research paper

B. a teaching plan

C. a book review

D. a diary

C

Making the transition (过渡) from college to the world of work requires more skills than simply signing up for courses and going to class. Before you set sail for the real world there are a few things you should consider.

Don’t wait until graduation is over before you start planni ng for your future. If you prepare early you will understand the job market and hopefully make some much needed contacts (联系). Also if you get really lucky you might be able to secure a job even before you graduate.

Getting an internship (实习) is good for many reasons. Not only can you network and get great experience, you can also decide if this particular aspect of your major is right for you. At the least you will feel secure about your choice and have some great references for your first interviews.

If you plan on continuing your education, try not to postpone (推迟) it. Some majors are only useful if you have a master’s degree or even higher. Check your major. Do you need more education to achieve your goals? If so, it is much easier to continue your education immediately after getting your bachelor’s degree.

Ask professors for references before you graduate. Don’t let graduation fly by without getting a written letter of reference from a few professors. Once you leave school it is easy for those teachers to forget why they liked you so much and what kind of student you were. Get the reference while you are fresh in their mind.

Keep in touch with other students in your field. Not only can students in your field become good contacts for you, they can also aid you in your job search or serve as motivation later on down the road. Exchange phone numbers and emails before you graduate. You never know how much motivation an old classmate can be.

44. What is the main purpose of the text?

A. To tell us how to sign up for courses to get practical skills.

B. To tell us how to make preparations for work before graduation.

C. To tell us the importance of practical skills in work.

D. To tell us how to plan for our future before graduation.

45. In terms of finding a job, the author probably thinks .

A. it’s nev er too late to find your favourite job

B. the earlier you prepare for a job, the better it will be

C. whether you can get a job largely depends on your luck

D. the time of graduation is the best time for you to find a job

46. We can conclude from the last two paragraphs that .

A. your professors and schoolmates are good sources for you before graduation

B. you’d better make friends with more professors and schoolmates at college

C. a schoolmate can be of more help to you than a professor

D. it’s also important to keep in touch with professors after graduation

47. The underlined word “secure” in Paragraph 2 has similar meaning to “”.

A. look for

B. apply for

C. know

D. find

D

Owning pet birds is not just feeding them when necessary. You have to be very responsible if you have decided to keep birds as pets. If you really want to acquire a companion, think in advance whether you are able to handle it.

Depending on what pet bird you are going to have and how big it is, the cost is different. For example, the cost of a comfortable cage, the cost for nutritional food and the money for some additional things should be taken into consideration. There are also some unexpected cost. For example, when your pet bird gets sick, you have to send for a vet (兽医).

You may think that you do not have free time to have a dog so you’d better have a pet bird because it doesn’t require a lot of attention. You are wrong! Some people even do not have time for a short sleep. They will not have enough time for pets, either. For good bird health it is very important to handle them and play with them as much as you can.

Also there are a lot of people who think that birds do not require a lot of space and they are wrong again. They also need to fly so if you do not have spac e for it, you’d better reconsider the things.

But do not forget the great advantage of having a pet bird. In the animal kingdom, birds rank near the top when it comes to smarts. You can have a friend for life if you take good care of it. It’s a real chara cter and can bring joy and colour in your home.

48. What is the text mainly about?

A. The advantages of keeping a pet bird.

B. The reasons for keeping a pet bird.

C. Things to consider if you want to keep a pet bird.

D. Different types of pets for different people.

49. We can learn from the second paragraph that .

A. you have to be very rich to keep a pet bird

B. some cost of keeping a pet bird is unnecessary

C. it is very easy to calculate the cost of having a pet bird

D. the cost of having a pet bird is unpredictable sometimes

50. If you want to have a pet bird, you needn’t consider.

A. the knowledge about a pet bird

B. the cost of having a pet bird

C. the time taken to care for a pet bird

D. the space a pet bird needs to fly

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。选项中有两项为多余选项。

Q&A

Question: Before graduation, I decided to be a useful man for our country. However, when I applied for some positions, I was turned down. Only then did I realize it was not easy to achieve my dream. 51 Now I even don’t have the courage to try a new position. How can I find the power to continue my dream?

Answer: I can understand the situation you are in. You feel your life lacks the power that you want and the motivation that you need. 52

By training your thoughts to concentrate on the bright side of things, you are more likely to have the incentive (动机) to work towards on your goals. 53

Your life can be improved, and your happiness enriched when you choose to change your views. Don’t leave your future to chance, or wait for things to get better mysteriously alone. 54 Begin to build your confidence, and work through problems rather than avoid them. Remember that power is not just about control over situations, but the ability to deal with whatever comes your way.

Always believe that good things are possible, and remember that mistakes can be lessons that lead to discoveries. Take your fear and transform it into trust. 55 Turn your “worry hours” into “productive hours”. You will see beautiful things happen when you allow yourself to experience the joys of life.

Balzac was good for buying things at its lowest prices. One day he wanted to buy a vase that was much more expensive than he can offer. Not being able to make the shopkeeper cut down its price, he left without further talking. Collected a half dozen of his friends, he explained his wish to them. They worked out a plan. The first one would enter into the shop and make an offer, lower than the marked prices. Not getting the vase, he would walk out. By this way, each of the others will offer a price lower than the one before. Before long Balzac himself would return and offer higher than the last two or three persons. The plan works.

One possible version:

In our daily life, we often buy packaged food. There is no doubt that it has many advantages. For example, it is convenient to carry and eat it. Besides, it can be preserved for a long time. However, we should be aware of the problems associated with packaged food. First, the preservative in packaged food might be harmful to our health. Second, some inferior package material will directly pollute the food. Moreover, the used packages will pollute the environment.

Personally I think pack aged food is convenient, but we can’t ignore its harmful effects.
