Have you ever wondered?
1.      Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.
2.      What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures(建筑物)float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.
小题1:What information can we get from the first passage?
A.It is the jet stream that affects how fast airplanes fly.
B.Planes go slower when they are moving with the wind.
C.It takes more time to fly from NY to London than from London to NY.
D.The jet stream always blows from the east to the west across the Atlantic.
小题2:The underlined word “shoot” in the 2nd paragraph means “_________”.
A.send for B.move quicklyC.come out D.grow quickly
小题3:It can be known that without gravity _________.
A.buildings and other structures would float away
B.trees and buildings would not so easily fly off
C.something around your head would not float away
D.everything outside buildings would fly off into space

A.In a research paper. B.In a short story.
C.In a travel magazine.D.In a student’s book

小题1:A
小题2:B
小题3:B

Middle school days are both fun and busy. Students spend their days in class,   1   to the interesting or sometimes boring words of their teachers. At break (休息) , they run, play and shout happily . Butshould students spend their free time after school?
In western countries,   3   is normal for students to have a part-time  4 after school or at weekends. Students can make their  5   money and learn more about the real world. They enjoy the independence (独立) and money, and their parents enjoy the quiet house. However, it seems that, in China, parents  6  so much about their children’s studies that they would like to see their children spending most of their time  7 for all those exams. It is natural for Chinese parents to feel that  8  , but I think everything should be kept in balance. Sometimes, western school children 9  long hours after school to make money, so they  10  too tired to listen in class or do their homework. But Chinese students spend so much time on their studies that all else becomes less important.

Do you know how to study better and make your study more effective(有效的)?We all know that Chinese students usually study very hard for long  35   .This is very good, but it doesn’t       36   a lot, for an effective student must have enough sleep, enough rest and exercise. Every day you need to go out for a walk or visit some friends or some nice places. It’s good for your study.
When you return   37   your studies, your mind will be refreshed(清醒) and you’ll learn more  38  study better. Psychologists(心理学家)  39  that learning takes place in this way. Here take English learning    40   an example. In the first few months you can make a lot of progress and you feel happy. Then your language study seems   41   the same. So you will think you’re learning  42  and you may give up. This can last for days or even weeks, yet you needn’t give up. At some point your language study will take another big  43  . You’ll see that you really have been learning all along. If you get enough sleep, food, rest and exercise, studying English can be very effective and interesting. Don’t  44  along the way. Learn slowly and you’re sure to get a good result.

Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors(拖拉机), rock music is also noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant(不断的) loud noise can cause a loss of hearing.
Scientists use a unit of measure called decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level(层次) causes the great hearing loss.

Sales of laptop computers passed desktops in the U.S. for the first time ever this fall, according to market-research firm IDC. That's bad news for backs, necks and shoulders.
Laptops are bad for our body. When you work at a computer, the keyboard should be at elbow height and the monitor should be roughly at eye level, so you can sit well in a chair. But most users simply set their laptops on a desk or table. The keyboard is too high, which makes your arms reach up, your shoulders feel tired and your wrists bend down. The monitor is too low, which pulls your head and neck forward and down and your back may feel hurt.
That's OK if you use your laptop for a short time. But if you use one for hours without stopping – as do millions of college students, business travelers, telecommuters, video-gamers and growing numbers of office workers – your body may feel hurt. Ergonomics experts have warned about laptop problems for years. But people still like laptops better than the desktops. And they use laptops anywhere – in bed, on the floor – in all kinds of positions.
“How can a mouse or a keyboard hurt you?” says Thomas Caffrey, the founder of Myofactors LLC, “Wrong positions can be bad for your body. As time goes by, a wrong position can lead to pain in the neck, shoulders, back and arms, as well as headaches.”
小题1:When you work at a computer, the keyboard should be ________.
A.at elbow heightB.at eye height
C.on a deskD.on a table
小题2:The writer asks us not to use the laptop ________.
A.for a short time B.to play video games
C.for hours without stopping D.to buy things on the Internet
小题3:From the passage, we know that laptop computers ________.
A.are not so popular as the desktops
B.are more popular than the desktops
C.are not bad for our body
D.have no mouse now
小题4:Using a laptop in a wrong position may make ________.
A.people’s sight lowerB.people have cancer
C.people’s arm longerD.people feel pain in the body
小题5:According to the passage, which of the following is NOT true?
A.When you use a laptop, you should put your monitor at eye height.
B.Laptop computers sold more than desktops this autumn.
C.To keep healthy, you should use laptop computers.
D.Business travelers often use the laptop computers for a long time.

Today Newtown is a clean place, but many years ago there were millions of rats there. The rats even attacked (攻击 ) the cats and dogs. Sometimes many of them tried to bite men or women at night. The rats were very large in size and they harmed (伤害 ) many people.
The city office ordered every one to kill rats. However, most people were lazy, so they did not kill many rats. The city office could do nothing with the citizens and could do nothing with the rats, either. Some time later, they had to pay some money for each dead rat. That made the people very happy. They at once began to kill rats. They got as many dead rats as they could. And some of them even stopped their own work to kill rats because they could get more pay. Every day a city official(官员 ) put all the dead rats together. He was very busy doing that, because sometimes a man brought hundreds of them in one day. Two weeks later, there were not so many rats in the city as before,  but people still brought many dead rats to the city office. The city officials felt surprised at this but at last they found out people were stealing the dead rats they had collected. So the city official had to order his men to dig a big hole and put the dead rats in it. Soon there were no more rats and the city did not have to pay any more money for that.
