第I卷(选择题)

第一节:阅读理解(共15小题;每小题2分,满分30分)

Driving from Downtown:

Drive along the Eisenhower Expressway west to First Avenue exit. Head south about 2.5 miles and follow the signs to the zoo entrance.

About the Brookfield Zoo:

The Brookfield Zoo is located just 14 miles west of downtown Chicago. It's home to a variety of animal species, and its use of natural barriers and moats (壕沟) is so much more relaxing and enjoyable than watching a lion pace back and forth in a cage. The absence of bars also makes for great wildlife photo opportunities. The Brookfield Zoo also focuses on education, with detailed displays about the animals being viewed and the interactive program that lets kids get some hands-on experience to learn what it takes to run a zoo as well as face painting and crafts.

“I like photography because it captures (捕捉) amazing things that you might not see again,” Timmy Walsh says. He takes pictures of flowers, sunsets and road signs. But those photos don't usually end up in a scrapbook (剪贴簿) or on his bedroom walls.

When Timmy was five, he found out that his aunt Bev had lung cancer. He wanted to do something to help her. His first idea was to sell his photos from a lemonade-type stand in front of his house in Pennsylvania. “My mom said it wouldn't work because we were not on a busy street,” Timmy explains.

His next idea was to have an art show. Timmy decorated his home with candles, flowers, and white lights. Then he arranged his photos. Timmy's mom, Sheila, remembers: “Our dining-room table was filled, the living room —everything was filled with photos.” Friends, family, an d Timmy's teachers came to the show. He raised more than $300 for cancer research that night. Aunt Bev was “very happy and excited,” he says.

After a local newspaper wrote a story about Timmy's photos, a volunteer offered to help him set up a website. As people learned about his cause, called Camera for a Cure, Timmy began receiving invitations to sell his pictures at art galleries and fund-raisers. Since then, his work has appeared in more than 20 shows.

When Timmy is at a show, he greets each customer and talks about what he was thinking when he took his photos. And he always shares facts about lung cancer. Sometimes donations and sales are slow, but that doesn't bother him. “It doesn't matter how much money we made because we just raised awareness,” he sa ys.

Timmy knows that finding a cure for lung cancer will take time and effort. So Timmy will keep doing his part by shooting and selling photos of the things he sees.

4. Before Timmy started Camera for a Cure, he _____.

A. had developed a deep interest in photography

B. had been providing photos for a local newspaper

C. always sold lemonade in front of his house

D. liked making scrapbooks by using his photos

5. What can we learn about the art show Timmy held at his home?

A. It cost $300 to organize it.

B. It was generally popular.

C. It was funded by Aunt Bev.

D. It was advertised on a website.

6. For Timmy, what's the benefit of selling his photos at art galleries?

A. Exchanging ideas with other artists.

B. Raising money more quickly.

C. Improving his photographic skills.

D. Increasing public awareness of lung cancer.

7. Which of the following can best describe Timmy?

A. Generous but self-centered.

B. Determined and warm-hearted.

C. Proud and confident.

D. Imaginative but cautious.

C

Our tiny boat was ploughing through (费力穿过) the waves across the Indian Ocean and I was absolutely freezing. The further we got from the shelter of the land, the more I thought how foolish I'd been to come along on this trip.

The pilot of the boat looked almost 60 but, perhaps because of a lifetime on the open sea in the hot sun, was very fit and strong. I was wondering how he managed to find his way. To me, it

seemed difficult enough to navigate a boat without any electronic equipment even on a sunny day.

So at least we were safe. But this was not what we had come along for. A look at the other divers' faces suggested that now they were also doubtful that we'd ever get the chance to see a whale shark — these weather conditions were totally unsuitable for diving! None of us spoke. It seemed too much of an effort. Then suddenly the boatman stopped the engine. He said a few words in his own language to the diving instructor, who immediately jumped up from his seat and told us to get ready to dive.

When I jumped into the grey sea, I was sure I wouldn't see anything. But then ... there it was! An enormous whale shark, slowly swimming through the water. I couldn't believe my eyes — my first whale shark! I hardly dared breathe —I was afraid my streams of bubbles (气泡) might scare the huge creature away. And the other divers were equally awed. Slowly we approached this huge animal. It was swimming quite slowly and we were able to swim with it, looking at the beautiful markings on its back. I was still holding my breath, telling myself that this huge fish was harmless! Then I reached out and touched it, stroking (轻抚) its thick skin. It was amazing how this giant suddenly gained speed — we watched it as it swam away from us, and a few moments later it was gone.

8. While riding a tiny boat across the Indian Ocean, the author _____.

A. volunteered to act as a pilot

B. felt regret about his decision

C. enjoyed the beautiful sunshine

D. talked with other people happily

9. The author probably wanted to know how the boatman _____.

A. kept fit in his spare time

B. spent his life on the boat

C. navigated his boat at sea

D. communicated with others

10. What was the purpose of the author's trip?

A. To swim the Indian Ocean.

B. To save underwater creatures.

C. To see a whale shark.

D. To learn how to dive.

11. How did the author feel after he jumped into the sea?

A. Doubtful and disappointed.

B. A bit tired but later relaxed.

C. Rather anxious and angry.

D. A little scared but excited.

D

Going for walks with my two-year-old son, I meet many nice people who ask what my job is. When I say that I teach at Swarthmore College, their faces light up, and the next question is, “What do you teach?” As they hear my answer “linguistics (the scientific study of language)”, they look confused. The smile on their faces tells me that they don't know what to make of my answer. If they are brave enough, they will ask, “So, what kinds of classes do you teach then?” Good question.

I have long been teaching pragmatics (语用学), a branch of linguistics. It is primarily concerned with how the context (上下文) in which a sentence is said influences its meaning. What “I'd love a glass of water” means largely depends on where and when it is said. In a restaurant, it will probably be understood as a request directed toward the waiter. Somewhere out in a desert, however, the same sentence is more likely to be interpreted as an impossible wish. Thus, although the literal (照字面本义的) meanings of two sentences could be exactly the same, their communicative meanings could be very different.

Interestingly, in pragmatics you will discover a message can be well communicated though not literally expressed. This takes place when the speaker and the listener share common ground.

If you see a car stopped on the side of the road, and you have the following exchange with the driver, you both know you've said enough to get your points across:

Driver: Hi. I ran out of gas.

You: There's a Shell just down the road.

Obviously, the driver is really asking something like, “Could you tell me what to do?” Your reply implies that there is a place nearby where the driver can get gas. No further explanation is needed because Shell, the name of a gas station, is part of their common ground.

12. What do we know about the people in Paragraph 1?

A. They are familiar with the author.

B. They work at Swarthmore College.

C. They know little about linguistics.

D. They hope to attend the author's class.

13. Why does the author say the underlined sentence has different communicative meanings?

A. Because their speakers are different.

B. Because their literal meanings are different.

C. Because their wishes are different.

D. Because their contexts are different.

14. Why did the car mentioned in the text stop?

A. To buy some gas.

B. To ask for help.

C. To wait for someone.

D. To take a short rest.

15. How does the author mainly explain pragmatics?

A. By analyzing major causes.

B. By making comparisons.

C. By using examples.

D. By presenting research findings.

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。

Everybody gets angry, but out-of-control anger isn't good for you or those around you. So here are five simple strategies to help you learn how to manage your anger:

? Relax. Breathe deeply, from your stomach. 16 Repeat it to yourself and visualize a relaxing time and experience.

? Change the way you think. When you're angry, your thinking can get exaggerated (夸大的). 17 For instance, instead of telling yourself, “Oh, it's terrible! Everything's ruined,” tell yourself, “It's understandable that I'm upset about it, but it's not the end of the world.”

? 18 Statements like “This never works.” or “You're always forgetting things.” will make you feel your anger is justified (情有可原的) and there's no way to solve the problem. They might upset people who might be willing to work with you on a solution.

? Have a better communication. Angry people tend to jump to conclusions. If you are in a heated discussion, slow down. 19 And take your time before answering. Instead of saying the first thing that comes into your head, think carefully about what you want to say.

? Use humor. Psychologists say that highly angry people tend to think “things ought to go my way!” “Silly humor” can help you get a more balanced pers pective. So, when you feel that anger coming the next time, picture yourself as a king or queen, walking around, admired by everybody, and getting your own way in every situation. The more detail you can get into your imaginary scenes, the more likely it is to put a smile on your face. 20

A. Try changing the topics so your talks won't turn into arguments.

B. Be careful with words like “never” or “always”.

C. Listen carefully to what the other person is saying.

D. Try replacing these thoughts with more reasonable ones.

E. Avoid using these strategies when you're in a tense situation.

F. Then slowly repeat a calm word or phrase such as “take it easy”.

G. That will help you realize that the things you're angry about are really not very important.

书面表达

One possible version:

Dear Mr. Smith,

I am Daming, a student from Class Five, Senior Two. I am writing to draw your attention to two improper behaviors among students in the reading rooms of the school library: making noises and littering. As you know, it is difficult for readers to focus while some students are whispering to each other or making cell phone calls. Besides, a dirty environment is not only bad for our health but also has a negative effect on our studying.

Therefore, in my opinion, some measures should be taken to solve these problems. First, put up some signs which forbid such improper behaviors. Second, ask all the students to pick up their rubbish when they leave.

Thank you for your consideration.

Yours sincerely,

Daming

高二下学期期中考试总结

高二下学期期中考试总结 紧张的考前复习,压制神经的考试,下考场后的议论纷纷,有人欢喜有人忧。全县统考结束后顿时感受轻松了不少,暂且别去说考试成绩的好坏,至少这种感受让人感到发自心里的放纵。随后而来的便是对考试成绩的焦急等待和新一轮学习的开始...也许以我这次的考试成绩并别能说成是优异,能够说算个中等吧。但关于我个人来说这也是一具进步,尽管有几科成绩别尽人意。下面就仔细分析分析吧。 先说说英语和历史吧。总体来说进入高中以来我的英语成绩呈现直线下滑趋势,这次也毫别出意外的只考了87分。我很清晰的知道考低分的原因:寻常老师让默写单词时别写,让记语法时别记。一到考试的时候就开始发愁,特别是在做单项挑选题的时候,单词疑惑什么意思感受哪个选项都对,语法疑惑如何运用感受哪个选项基本上答案,结果惟独乱猜了,这次考试在这方面就吃了大亏了。历史这科自我感受依然挺简单的,因为上次考试还得了80多分呢,我想的是这次至少能够考85分的,结果特别完美的验证了一具词语:眼高手低。成绩下来只考了66分。尽管说这次全校历史成绩都有所下滑,但是得高分的依然有的。这次历史成绩给了我别小的打击,更何况老班是算是由历史老师,的确有点别给他面子了。寻常历史学的还挺卖劲的,对历史也是有浓厚的兴趣的,可考试怎么说是考试,后面的非挑选题都是基本上只得了一半的分,未来可得注意了。再说说政治吧。说句实话《日子与哲学》这一册的知识比较难理解,寻常的学习也不过死记,全然别太理解其中的含义,寻常做练习题也别注意总结,结果考试的时候后面的咨询答题都是是胡写的,想到哪一点就写哪一点,没有头绪没有要点。有因必有果:有两个大题别得分,有一大题只得了一分,在整张卷子上拉了将近30分,尽管挑选题做的还能够,但分数也都是定格了,只考了59分。看看分数再想想自己在课堂上的表现:睡觉,发呆...特别是老师说练习题的时候都是是别听的,以至于对张老师说的咨询题分析、做题思路都毫无印象,考试的时候为所欲为,乱答一气。如今终于知道自己有多笨了,真懊悔。 数学和语文成绩小有进步。语文就别用说了,数学可是个难题。说句实话,数学有25分的挑选题别是我自己做的,后面的大题自己苦心专研的。自认为很简单的,结果很别爽的有两道大题别得分。挑选题在别人的热心帮助下错了两道,还别错。事实上,这段时刻可没少在数学上下功夫,终于功夫别负有心人得了92分。语文得了115分,我最开心的是语文没有低于110分过,但成绩还有待更进一步。最后说说地理吧。事实上高一上学期学自然地理的时候,我的地理成绩依然一踏糊涂,但在这种极其惊险的事情下,我依然毅然挑选了文科。为了补瘸腿科,我对地理学习也分外的努力。高一下学期是人文地理,比较简单,渐渐的我的地理成绩也有所上升。事实上能有如此的成绩和地理老师和老师是分别开的。刚开始学习地理的时候我别敢向老师咨询题,也从来没有咨询过。高一下学期和老师开始带我们班地理之后这种事情才有所改变,渐渐的也就没有什么胆怯的了。时刻长了对地理也产生了浓厚的兴趣。这对我将来的学习产生了很大的妨碍。这次地理成绩还算理想,考了83分。我想这与我平时的训练是分别开的,特别是考试前对基础知识的复习和对往常做过的练习题的复习,但是挑选题错的太多,错了5道,都是好基本上寻常老师说过的,真别应该。总体上来说,这次考试题别算太难。但由于自己的粗心大意依然吃了很多亏。未来一定要注意。 别管如何样,这次考试差不多结束了,成绩的好坏也差不多成了定局。但它只能代表过去,别能对自己的以后做判决。这次考试给了我很大的启示,也让自己看到了自己的缺点与别脚,有了这次的考试经验,将来我一定注意改正自己在学习中的缺点,弥补自己的别脚,争取再创一具更好的成绩! 命运如同手中的掌纹,不管再如何蜿蜒但终究在你手中。要知道,没有等出来的漂亮,惟独拼出来的辉煌!

高二年上学期英语期中考试试卷 一、阅读理解 1. 阅读理解 Some people seem to have extraordinary memories. Zheng Aiqiang,a “memory athlete” on TV show Super Brain, can remember 2,660 numbersin just one hour! You would think people like this have special brains. But accordingto a recent study by researchers from the US and the Netherlands, the brain structuresof ordinary people and 23 of the world’s leading memory athletes show no difference. That’s because good memories can be trained. New research inthe journal Neuron suggests that you can become a super memorizer with just sixweeks of hard training. Researchers found that technique called loci, invented by ancient Greeks,can greatly help improve memory. By using loci, you are using your imagination toimprove the brain’s memory ne tworks. You can link something you need to remember with aplace that you know very well. For example, to remember a list of numbers, imagineyourself walking through your house.
