It amazed me—every ( http: / / www.21cnjy.com )time I saw Joe he was smiling. It didn't matter whether he had to stop at a stop light，or if he was the seventh person in line at the bank，and the teller (出纳员) ended her job just before he got there. Joe always smiled. It made me wonder why he always seemed so happy.21教育网
Having observed Joe ( http: / / www.21cnjy.com )with other people，I noticed something else too. Joe asked people how they were doing，and really seemed to listen to their answers. He showed pity to someone who was hurting，and had kind words，and offered to help in any way he could.
It made me think. ( http: / / www.21cnjy.com ) What if I tried to smile more？An experiment began when I went to the supermarket. I smiled as I went up and down the supermarket and people I didn't even know smiled back at me. Some even spoke！The little kid in the cart who was giving his mother a hard time saw me smile；he stopped talking and then made a shy attempt at a smile. The man in the cart for the disabled needed help to reach for something，and I got it for him. The smile even transferred (转移) over to him，and he thanked me.
As I drove home，I ( http: / / www.21cnjy.com )was smiling. Now I know a smile is a small thing，but what if we all tried to smile a few more times each day？I couldn't believe how great I felt. Nothing in my life had changed，but maybe it had. What I had learned was that such a small thing could lift not only my spirits，but also the spirits of those around me. So smile!

My mother loves flo ( http: / / www.21cnjy.com )wers. As soon as warm weather comes around，you will find her planting，watering and weeding over everything. For many years we lived next door to each other，and she spent as much time in my garden as she did her own. After the flowers became plentiful each summer，she would cut colorful bouquets (花束) to enjoy inside the house—both hers and mine. I would often come home from work and find a beautiful arrangement (布置) of fresh flowers on my coffee table.【版权所有：21教育】
Shortly before ( http: / / www.21cnjy.com ) Christmas one year，a local flower shop offered a bouquet—a month special. It seemed to be a great way to thank her for all of the flowers she had given me through the years.
After the hol ( http: / / www.21cnjy.com )idays，in early January，I drove her to the flower shop to pick up her first month's bouquet. The small fresh colorful bouquet would hardly fill a small vase (花瓶)．
I was so embarrassed ( http: / / www.21cnjy.com )(尴尬的)．However，after we returned home，she began to arrange the flowers she had received.“Mom，I'm sorry，” I told her.“I can't believe how skimpy that bouquet is.” She looked at me and smiled. “It's okay，” she said.“It allows me to better enjoy the beauty of each one.”21·cn·jy·com
Mom's words helped me ( http: / / www.21cnjy.com )to realize something bigger and more important—when we have too many good things，we often fail to enjoy the beauty of each one.
Thanks，Mom，for helping me understand that less is sometimes more.

Peer (同龄人) pressure is ( http: / / www.21cnjy.com ) all about being forced into a certain way of living, dressing, talking, socializing and even thinking—simply because that is how everyone else you know behaves, dresses, talks, socializes and thinks.
Young people c ( http: / / www.21cnjy.com )an be often insensitive in their dealings with each other. And they are very quick to notice differences of habit, dress and social behavior. As a result, you might have to buy the latest fashions in clothes and other things. Because everyone else does the same, regardless of cost or comfort. You might end up reading what they read, watching the same television programs and movies that others watch and using the same language that they use. Because, otherwise, you feel left out of all the conversation. You might end up staying out late at night or eating out all the time, simply because that is what the others do, regardless of whether you can afford to or not.
The best way to ( http: / / www.21cnjy.com )deal with peer pressure is to select your friends very carefully. Preferably, your friends should be in a mixed group of people. That keeps everyone rooted and more tolerant of differences.【来源：21cnj*y.co*m】
The second is to gath ( http: / / www.21cnjy.com )er your courage and to tell people to mind their own business, if and when they begin to interfere with your life. Sure, a few people may be offended (冒犯). But they will also learn to be less offensive themselves, in future.
And most importantl ( http: / / www.21cnjy.com )y, you have to remember that you are unique in this world. And your decisions to eat, drink, dress, talk, go out, read or think are your own. If others don't share these interests or habits, too bad. Let your peers and friends catch up with you. If they can't, find new friends.
51．If you are for ( http: / / www.21cnjy.com )ced into a certain way of thinking and acting like everyone you know, you ________.
A．are suffering from peer pressure
B．are losing yourself
C．are learning from them
D．are getting on well with them
52．Why might you ( http: / / www.21cnjy.com ) have to buy the latest fashions in clothes and other things
A．Because you like them.
B．Because you want to catch up with others.
C．Because they look fashionable.
D．Because you can afford them.
53．Which is the best way to deal with peer pressure
A．To select your friends carefully.
B．To keep away from others.
C．To tell others what you like.
D．To be more tolerant of differences.
54．How many ways to ( http: / / www.21cnjy.com ) deal with peer pressure are mentioned in the text

Ⅳ.阅读表达(共5小题；每小题3分，满分15分)
Have you had a he ( http: / / www.21cnjy.com )adache during a test Have you ever been so worried about something that you have a headache or even can't sleep at night If so, then you know what stress is. Stress is what you feel when you are worried about something. This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid—all these can give you a stomachache or a headache.
However, there are ( http: / / www.21cnjy.com ) different kinds of stress. Some kinds of stress are good and others are bad. Good stress might happen when you're called to answer questions in class or when you have to give a speech. This kind of stress can help you to get things better done. For example, you may do a better job on your test if the stress pushes you to prepare better before the test.
On the other hand, ( http: / / www.21cnjy.com )bad stress can happen if the stress lasts too long. ________________ if your parents are fighting, if a family member is sick, if you're having problems at school, or if anything else makes you unhappy every day. That kind of stress isn't going to help you. And it can actually make you sick.
The best way ( http: / / www.21cnjy.com ) to fight the stress is to have a balanced life. Make sure you keep yourself in mind: sleep, exercise, leisure(休闲)，and food. If you get enough sleep and eat properly, and if you exercise and leave time for fun, you'll probably feel less stressed.

Ⅲ.阅读理解
A
There are many inte ( http: / / www.21cnjy.com )resting science experiments out there for young kids. You can wow your friends and teachers with them. All you have to do is to put a little effort into it and you should have no problem coming up with an interesting science experiment. One such experiment is to show your friends and teachers that you can make mothballs (樟脑丸)dance!
If you want to do it, ( http: / / www.21cnjy.com ) first, be sure that you have got all the necessary science kits for your science experiment.21·cn·jy·com
What you need f ( http: / / www.21cnjy.com )or this experiment is a glass filled half full with water. Add a little bit of vinegar to your glass of water, about 1/3 or 1/4 of a cup (60 ml), and one teaspoon (10 ml) of baking soda, and then carefully stir the mixture. Drop a few mothballs into the glass and have your audience watch. As long as the surfaces of the mothballs become fairly rough, they should begin to bounce up and down in the glass.2-1-c-n-j-y
You can also do ( http: / / www.21cnjy.com )a similar experiment with raisins (葡萄干) and clear pop，such as Sprite. In this experiment, all you have to do is to fill a glass with Sprite and drop a few raisins into it. The raisins should begin to bounce up and down in the glass of Sprite. You can also replace the raisins with mothballs and you should get the same effect in the Sprite. This project works because the irregular surfaces of the mothballs and the raisins hold some CO2 bubbles(气泡), causing them to bounce up and down in a dancing motion.
1．The writer wrote this passage to________.
A．explain why some science experiments are easy
B．encourage people to spend more time on science
C．tell us how good he is at doing science experiments
D．teach kids how to do an easy and interesting science experiment
2．What is the most probable name of the experiment
A．Producing mothballs.

D．Swimming mothballs.
3．Which of the following things are needed in the experiment
a．baking soda b．water c．mothballs d．salt
e．vinegar f．sugar
A．bcef B．acde
C．abcd D．abce
4．The underlined word ( http: / / www.21cnjy.com )“pop” in Paragraph 4 probably refers to a ________.
A．mothball B．kind of vinegar
C．drink with bubbles D．special kind of raisin
5．From the last paragraph we can know ________.

B
Are you tired？Do ( http: / / www.21cnjy.com )you often catch colds and flu？If so，you might consider changing your sleep habits. Good health demands good sleep. Studies have shown that most people need eight hours of sleep each night. Americans，however, on average, get only seven hours. One third of us get just six hours，and good health is not simply a matter of how much sleep you get，but also the type of sleep you get.21世纪教育网版权所有
Non rapid eye movement ( http: / / www.21cnjy.com ) (NREM) sleep allows your body to grow and repair itself. During NREM sleep，your muscles relax. Your heart rate and breathing rate decrease. Your eyes roll slowly back and forth then they stop moving. Most of the sleeping you do is NREM sleep.
Rapid eye movement (RE ( http: / / www.21cnjy.com )M) sleep restores your brain. During REM sleep，you dream. You may not remember every dream，but every time you sleep，you dream. Your eyes move back and forth quickly. Your breathing rate and heartbeat increase. Your muscles become paralysed (麻痹的)．About 25 percent of your sleep is REM sleep. You need enough of both kinds of sleep to be healthy.2·1·c·n·j·y
Is it a real concern ( http: / / www.21cnjy.com ) if you don't get enough good sleep？It certainly is. Poor sleep puts you and others at risk. More than 100,000 car accidents are caused each year by drivers who nod off (打盹)．Almost $100 billion is lost yearly in the business and environmental field. People deprived_of sleep have been factors in the Challenger space tragedy，the Exxon Valdez oil spill (溢出)，and the Chernobyl nuclear reactor accident. So do yourself and everyone around you a favour. Don't cheat yourself out of good sleep!www-2-1-cnjy-com
6．This passage is mainly about ________.
A．why people dream
B．what happens during REM sleep
C．why people catch colds and flu
D．the importance of sleep
7．Most sleep at night is ________.
A．NREM sleep
B．REM sleep
C．good quality sleep
D．sleep that makes you become paralysed
8．“Good sleep” can be described as ________.
A．getting about eight hours of the two types of sleep【出处：21教育名师】
B．sleeping soundly through the night
C．getting more than seven hours of sleep each night21教育名师原创作品
D．having sleep that prevents accidents
9．To help the readers ( http: / / www.21cnjy.com )understand the effects of poor sleep habits，the writer ________.
A．explains the two types of sleep
B．compares the two kinds of sleep
C．mentions several disasters

4．C 词义猜测题。根据“such ( http: / / www.21cnjy.com )as Sprite以及hold some CO2 bubbles”可知pop在这里是指含有二氧化碳的饮料。

8．A 由第一段第四句“Studies ( http: / / www.21cnjy.com )have shown that most people need eight hours of sleep each night”，和第二段最后一句“You need enough of...to be healthy”可知，好的睡眠要两种睡眠方式，故A项正确。【来源：21·世纪·教育·网】

10．B 文章最后一段主要是说明睡 ( http: / / www.21cnjy.com )眠不足所带来的危害，由此推断“People deprived of sleep”应该是指睡眠不足的人，故正确答案为B项。

Ⅳ.阅读理解
When Albert Ein ( http: / / www.21cnjy.com )stein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty learning to read.
When Albert was fi ( http: / / www.21cnjy.com )ve years old, his father gave him a compass(指南针)．Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction—to the north. He asked his father and uncle what caused the needle to move.
Their answers wer ( http: / / www.21cnjy.com )e difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be behind things.
Albert did not like s ( http: / / www.21cnjy.com )chool. The German schools at that time were not pleasant. Students couldn't ask questions. Albert said he felt as if he were in prison.
One day Albert to ( http: / / www.21cnjy.com )ld his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by thinking like a policeman. “You are looking for someone，” he said. “But you do not know who he is. Call him X. Find him by using your mathematical tools.”
Albert learned to l ( http: / / www.21cnjy.com )ove mathematics. He was studying the complex mathematics of calculus(微积分学)when all his friends were still studying simple mathematics. Instead of playing with friends he thought about things such as “What would happen if people could travel at the speed of light？”
Albert wanted to ( http: / / www.21cnjy.com ) teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job.2-1-c-n-j-y
