Are you interested ( http: / / www.21cnjy.com )in doing scientific experiments If you are, follow the following instructions and do an experiment in your home.21cnjy.com
NAME: Candle time and room temperature
MATERIALS: 15 med ( http: / / www.21cnjy.com )ium size wax candles, air conditioning, a space heater, a nail or a fork, and three thermometers
INSTRUCTIONS：
1．Come up with your ( http: / / www.21cnjy.com )hypothesis(假设)—do you think that candles will burn faster in warm or cold environments
2．Measure your can ( http: / / www.21cnjy.com )dles. They should all be brand new, so all of them should have the same length.
3．Run the air condi ( http: / / www.21cnjy.com )tioner in one room, space heater in another, and leave another room at a mild temperature. Leave a thermometer in each room and wait for the temperature to adjust (one hour or so)．

It amazed me—e ( http: / / www.21cnjy.com )very 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.【版权所有：21教育】
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. W ( http: / / www.21cnjy.com )hat 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 wa ( http: / / www.21cnjy.com )s 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 flower ( http: / / www.21cnjy.com )s. 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.
Shortly before Chr ( http: / / www.21cnjy.com )istmas 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 holidays， ( http: / / www.21cnjy.com )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.”
Mom's words helpe ( http: / / www.21cnjy.com )d me 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) pressur ( http: / / www.21cnjy.com )e is 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 can be ( http: / / www.21cnjy.com ) 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 t ( http: / / www.21cnjy.com )o 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.
The second is ( http: / / www.21cnjy.com ) to gather 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 importantly, ( http: / / www.21cnjy.com ) 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.
43．Why might you have ( http: / / www.21cnjy.com )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.
44．How many ways to de ( http: / / www.21cnjy.com )al with peer pressure are mentioned in the text
A．One. B．Two.
C．Three. D．Four.
45．The main purpose of this passage is ________.
A．to tell young people how to get along with their friends
B．to tell young people how to catch up with fashion
C．to tell young people how to live an independent life
D．to tell young people how to deal with peer pressure

Many businesse ( http: / / www.21cnjy.com )s today use conferences as a means of discussing new plans of the company.As people are paying more attention to the environment and green problems，more businesses are looking for ways to reduce their negative effect on the environment.Many businesses do this by using Web conferencing.【来源：21·世纪·教育·网】
Web conferencing ( http: / / www.21cnjy.com ) is a technology that allows people to communicate more effectively over the Internet.It's an easy way of hosting and attending conferences without having to leave the office.Each of the people involved in a Web conference will be posted an invitation to the conference with the time and date of the Web conference on it.When the conference is ready to begin，all participants(参与者) must sit at their computers and they will be connected over the Internet.
With Web conferencing ( http: / / www.21cnjy.com ) all participants attend the conference from the comfort of their own desk.Obviously，in doing this no fuel is used in traveling to and from a conference，and less work time is taken up in attending a conference.
Any material to be ( http: / / www.21cnjy.com )used during Web conferencing is simply e mailed to all the participants before the conference.Participants can then either choose to print material or read it on screen.This not only saves paper but also greatly reduces mailing costs for the business.
As a conference h ( http: / / www.21cnjy.com )all or business center isn't being used，it means that the only power that is used is the power used by the participants' personal computers.Similarly conference organizers don' t have to arrange for food or overnight accommodation(住宿) for participants of their conferences.All this means that less energy is used. 21*cnjy*com
Often in busines ( http: / / www.21cnjy.com )s some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment.And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.
So Web conferencing ( http: / / www.21cnjy.com ) is much cheaper and greener and more people are willing to host and attend a Web conference.
46．What is the passage mainly about
A．Ways of protecting the environment.
B．Green benefits of Web conferencing.
C．Ways of hosting a Web conference.

A．are interested in using any new technology

We have two daug ( http: / / www.21cnjy.com )hters: Kristen is seven years old and Kelly is four.Last Sunday evening，we invited some people home for dinner.I dressed them nicely for the party，and told them that their job was to join Mommy in answering the door when the bell rang.Mommy would introduce them to the guests，and then they would take the guests' coats upstairs and put them on the bed in the second bedroom.21教育网
The guests arrive ( http: / / www.21cnjy.com )d.I introduced my two daughters to each of them.The adults were nice and kind and said how lucky we were to have such good kids.
Each of the g ( http: / / www.21cnjy.com )uests made a particular fuss over Kelly，the younger one，admiring her dress，her hair and her smile.They said she was a remarkable girl to be carrying coats upstairs at her age.
I thought to my ( http: / / www.21cnjy.com )self that we adults usually make_a_big_“to_do”_over the younger one because she's the one who seems more easily hurt.We do it with the best of intentions.But we seldom think of how it might affect the other child.I was a little worried that Kristen would feel she was being outshined.I was about to serve dinner when I realized that she had been missing for twenty minutes.I ran upstairs and found her in the bedroom，crying.【来源：21cnj*y.co*m】
I said，“What are you doing，my dear？”
She turned to me with ( http: / / www.21cnjy.com )a sad expression and said，“Mommy，why don't people like me the way they like my sister Is it because I'm not pretty Is that why they don't say nice things about me as much？”
I tried to explain ( http: / / www.21cnjy.com ) to her，kissing and hugging her to make her feel better.
Now，whenever ( http: / / www.21cnjy.com ) I visit a friend's home，I make it a point to speak to the elder child first.

Everyone in ou ( http: / / www.21cnjy.com )r village likes my father, so he has a sense of humor. On other words, he can make others laugh easy and people feel happy to be around him. I admire him very much and dream of that some day I will be as humorous as him. I even asked him how have a good sense of humor, but what she replied disappointed me. “Not someone can be humorous, because those who is humorous are usually born to be humorous，” he said. However, later, he adds, “But you can be humorous too if you know a lot of joke.” That's why now I'm reading a book of jokes.

A
There are many interes ( http: / / www.21cnjy.com )ting 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 ( http: / / www.21cnjy.com ) it, first, be sure that you have got all the necessary science kits for your science experiment.2·1·c·n·j·y
What you need for this ( http: / / www.21cnjy.com ) 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.
You can also do a simi ( http: / / www.21cnjy.com )lar 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.【出处：21教育名师】

Are you tired？Do you o ( http: / / www.21cnjy.com )ften 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教育网
Non rapid eye movemen ( http: / / www.21cnjy.com )t (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 mov ( http: / / www.21cnjy.com )ement (REM) 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.www.21-cn-jy.com
Is it a real concern i ( http: / / www.21cnjy.com )f 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! 21*cnjy*com

6．D 文章第一段讲述了健康与睡眠的时 ( http: / / www.21cnjy.com )长和类型有关，文章第二、三段介绍了两种睡眠方式，最后一段说明睡眠不足所带来的害处，因此全文的中心是睡眠的重要性，故答案选D项。21cnjy.com

When Albert Einst ( http: / / www.21cnjy.com )ein 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.21教育名师原创作品
When Albert was fiv ( http: / / www.21cnjy.com )e 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 we ( http: / / www.21cnjy.com )re 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 lik ( http: / / www.21cnjy.com )e school. 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 Alber ( http: / / www.21cnjy.com )t told 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 love ( http: / / www.21cnjy.com ) 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 te ( http: / / www.21cnjy.com )ach 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

8．ordinary 9.form 10.aims
Ⅱ.1.A 考查冠词和名 ( http: / / www.21cnjy.com )词equipment。句意：——你看了那个著名导演执导的新电影了吗？据说很成功。——没有，我这些天一直忙着准备所有的办公设备。success抽象名词具体化，前面加a指一件具体成功的事或一个成功的人，在此句中指一件成功的事。equipment是不可数名词，没有复数形式，故答案为A。

7．C 考查分数表达法和主 ( http: / / www.21cnjy.com )谓一致。句意：这个区域的五分之二的土地被树和草覆盖着。分数表达法为分子用基数词，分母用序数词，当分子大于一时，分母用复数，故五分之二表达为two fifths，分析句子结构可知句子主语为land，是不可数名词，故谓语动词用第三人称单数形式，答案为C。
8．B 考查it作形式主语 ( http: / / www.21cnjy.com )。句意：著名科学家下周将给我们做如何预测地震的报告，这是真的吗？it在此处作形式主语，真正的主语是后面的that从句。

11．A 句意：每个学生都把一根手指放在老 ( http: / / www.21cnjy.com )师刚才调好的混合物中蘸了蘸并尝了尝。mixture名词，指“混合物”；mixed为动词的过去分词形式。21cnjy.com

13．A 人生中重要的事情，且与工作和汽车同等重要的，应该为A项较合适。
14．B 从本段和最后一段可知，没有提到的就只有沙子了，因此，文中将沙子比喻成小事。

16．A 根据文章中的第七段的第一句话可知。
17．B 生活中如果将精力和时间花费在小事上，就不会有空间给重要的事了。
