I wrote down the names of all my close friends.I found out that none of my close friends were in any of my new classes. Also, my new classmates were quite different from my old ones. I thought they weren’t as clever as my old classmates. They also weren’t in the school activities I was in. I couldn’t find the same interests with them.As the year went on, I began to feel lonely and envy(羡慕)people in other groups. Why could they be with all their friends? As I found out, they didn’t have many friends at first. They had made new friends in their new classes. They looked really happy with their new friends.I decided it was time for me to make new friends. I found that the people with many friends were very active(活跃的). They often talked to others first, while I was too afraid to talk to others and hoped other people would talk to me first.Once I realized(意识到) that, I found that making friends is very easy if you can accept(接受) people for who they are, respect(尊敬) them, and talk to them.

The writer wants to tell us that ________.A. it’s difficult to make new friendsB. the school needs much money to runC. being active(主动)is good for making friendsD. it’s not good to envy your close friends(C)In learning English, one should first pay attention to(注意)listening and speaking. It is the groundwork of read ing and writing. You’d better try your best to speak while you do much listening. Don’t be afraid of making mistakes. Be careful not to let them stop you from improving (提高)your English. While you are doing this, a good way is to write—keep a diary, write notes or letters; then if you can, ask some people to go through what you have written and tell you what you’ve done wrong. Many mistakes in your speaking will be easily pointed out in your writing. Through correcting(纠正)the mistakes, you can do better in learning English.If you are slow in speaking, don’t worry. One of the helpful ways is reading, either aloud or to yourself. The important thing is to choose something interesting to read. It mustn’t be too difficult for you. When you are reading in this way, don’t stop to look up the words if you can guess their meanings. When they have nothing important to do with the sentence, you can do that some other time.( )11.

(4分)作家余华说过,“生活越是平淡,内心越是xuàn烂”,这句话我十分认同。

我见到过生活中的一些作家,老实,羞sè,甚至木讷,接近于迂腐。

但他们的文字,张狂凌厉,似锋利小刀,处处露出锋芒。

也许所有情绪别无居处,只能chángyáng在文字里。

文字是他们小小的外衣,穿上可以是皇帝,在自己的王国里豁达洒脱。

管它呢,这是我的领土——可以尽情去爱,亦可以尽情去恨。

爱与恨,原来都可以这样肃杀,这样浩荡。

Kate MortonB. Helen ScottC. Laura BushD. Carol BrownB“Go for it!”The expression “Go for it!” is a way of encouraging someone to try something. “Go for it!”means you should not worry about failure or be too careful. You should take a chance and be brave.“Go for it!” gets its name from football. But it is not the football played in most countries such as England, France or Japan, but the kind of football played in the United States and Canada.One of the most exciting times in football comes when a team has failed, after three tries, to move the ball forward ten yards. The team must make a very important decision.The conservative (保守的) choice is to kick the ball and accept temporary defeat (暂时的失败) in order to get a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to get the remaining yards needed.People now are certain to shout their advice. Some will shout, “Kick the ball!”But others will encourage the team to take a chance. “Go for it!”they will shout loudly.In the 1980’s, people began using this expression in many kinds of situations to encourage someone to act bravely.There is no guarantee (保障) that the action you “Go for it!” will succeed. But that is the chance you take when you decide to go for it. You put your fears behind. You choose courage over safety. You hold your breath and go for it.36. What does “Go for it!” mean?A. You should go straight on.B. You should take a chance and be brave.C. You should go to school and ask teachers for help.D. You should be very careful.37.

We need to make a quick decision at the last momentD. We have to make a choice between success and failure.40. The writer makes his idea clear by __________.A. giving explanationsB. making comparisons (比较)C. telling storiesD. using famous people’s wordsCWhen I was fourteen I was hit by a car and I felt almost senseless fromthe waist down. I spent the next four years wearing a back support.I began running seven days a week to strengthen my muscles (肌肉). Itwas exhausting but I got well before I graduated from high school.When I was thirty-one, I was in another car accident in which my legswere seriously injured. The doctors told me that their goal was to get me to walk “normally”, but that I would never run again. Stubborn and determined, however, I set out to rebuild my leg muscles to support my knees through my own personalized training program. The fact was it took me two years to learn how to walk and nine and a half years to run again.One day, when I was running, a crazy thought entered my mind: What if I could run the LA Marathon? I wanted to know what it felt like to cross the prized finishing line, even if it meant I had to crawl (爬) across it.I had only four months to get ready. I spent almost all my time training. I knew that if I didn’t train to my fullest, my body would break down and the doctors’ diagnosis (诊断) would win.I wasn’t about to let that happen. I had a dream: I would run the LA Marathon to achieve one of my life’s greatest goals. I trained eight times a week, seven days a week and even twice a day.Finally, my hard efforts worked. I crossed the finishing line of the LA Marathon, strong and solid.I’m often asked why I run, to which I always reply, “I run because I can.” I remind myself that the aches and pains I experience while training and racing are nothing, compared to the suffering those whom I admire must bear. This is why Irun.41. After the second car accident, the doctors thought .A. the writer couldn’t walk any moreB. the writer couldn’t walk like othersC. everything would be fine later onD. it was hard for the writer to run42. From the passage we know that the writer .A. did what the doctor told him to doB. had a car accident in primary schoolC. practiced hard in LA Marathon HospitalD. could give people a reason why he ran43. According to the passage, we know the writer is ______.A. luckyB. cleverC. strong-willedD.warm-hearted44. The underlined part “I run because I can” in the last paragraph refers that the writer .A. completely believed in himselfB. made every effort to be normalC. proved he was fine like othersD. didn’t agree with his doctors45. It can be learned from the passage .A. one is never too old to learnB. where there is a will, there is a wayC. all that ends well is wellD. running keeps the doctor awayDEmpathy (同情心) lets us feel another person’s pain and drivers us to help. Do any other animals feel empathy? Scientists recently found that rats do, too. Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain. Scientists placed pairs of rats in plastic cages for two weeks. During this time they got to know each other. Then they put one of the rats fromeach pair into a small container (容器) in the cages. The smallcontainer had a door. It was rigged to fall to the side whenthe free rat touched it. Many of the trapped rats squeaked (吱吱叫) to express their discomfort. The other rats of the pairs could see their suffering friends clearly.In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it untilthey had saved their friends successfully. Scientists also found that female rats tended to act more empathetic than male rats.“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees(黑猩猩) have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”46. A person with empathy is often _________.A. kind-heartedB. cleverC. activeD. strong47. Why didn’t the free rats eat the chocolate at first?A. Because they were not hungry at that time.B. Because chocolate was not their favorite food.C. Because they wanted to save the trapped rats first.D. Because they were afraid that the chocolate was bad.48. Which of the following animals were NOT mentioned in the article?A. Monkeys.B. Chimpanzees.C. Rats.D. Cats.49. What does the word ‘discomfort’ in Paragraph 3 mean?A. happinessB. illnessC. uneasinessD. anger50. What does the passage mainly tell us?A. Rats can feel other animals’ pain.B. Chocolate is rats’ fa vorite food.C. Rats are empathetic and can feel each other’s pain.D. Female rats are more empathetic than male rats.第二部分非选择题部分(50分)四、阅读表达 (共5小题每小题2分,满分10分)A group of class friends successful in their careers got together to visit their old university professor. Their talk soon turned into complaints about stress in work and life.Offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and several cups —porcelain (瓷的), plastic (塑料的), glass, crystal (水晶的), some common, some expensive and some delicate (精美的) — telling them to help themselves to the coffee.(1)When all the students had a cup of coffee in hand, the professor said, “If you noticed, all the nice-looking expensive cups were taken up, leaving behind the _________ and _________ ones.While it is natural for you to choose only the best for ourselves, that is the cause of your problems and stress. The cup itself adds no quality to the coffee. (2)What all of you really wanted was coffee, not the cup, but youconsciously (有意识地) went for the best cups. And then you began eyeing other people’s cups. Now consider this: life is the coffee; the jobs, money and position in society are the cups. They are just tools to hold and contain life, and the type of cup which we have will not change the quality of life we live. Sometimes, by fixing our attention only on the cup, we fail to enjoy the coffee which God has provided for us. God brews (冲泡) the coffee, not the cups...Enjoy your coffee!”Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God.1. 在(1)处横线上填入适当的单词使上下文通顺。
