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.”
小題1:When you work at a computer, the keyboard should be ________.
A．a(chǎn)t elbow heightB．a(chǎn)t eye height
C．on a deskD．on a table
小題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
小題3:From the passage, we know that laptop computers ________.
A．a(chǎn)re not so popular as the desktops
B．a(chǎn)re more popular than the desktops
C．a(chǎn)re not bad for our body
D．have no mouse now
小題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
小題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.

Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the earth only a few unusual plants can grow. That’s why dry deserts everywhere are almost not covered by trees or grass.
Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.
小題1:What things don’t most plants need to grow well according to the passage?
A．Warmth.              B．Food.                C．Sandy beach
小題2:What does the underlined word “cracks” mean in the passage?
A．表面             B．縫隙                 C．夾層
小題3:From the passage, we know that it is        for plants to grow in dry places.
A．difficult                B．impossible           C．important
小題4:The reason why most plants can’t grow on the sandy beach is that       .
A．there isn’t enough sunlight
B．there is too much water
C．it has little food for plants
小題5:The passage can most probably be found in a        book.
A．science              B．history              C．travel

  We use the Internet for many things: business, shopping, writing letters, talking to people, finding information and so on. In recent years a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases into a few letters called acronyms. Acronyms are often used in chat rooms. Some of them are
BTW (by the way)        BRB (be right back)
LOL (laughing out loud)    IMO (in my opinion)
People also use many abbreviations(縮寫). They are shortened forms of words. Some common abbreviations are:
Info(information)       puter (computer)
Pie(picture)           sec (second)
We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keywords to draw “feeling”, such as:
:-)(happy)    :-p(joking)   :-( (sad)    :-0 (surprised)
These days, many forums(論壇) have picture feelings. For example,

(sad)      (happy)
There are even whole new words, like“newbie’s”(someone who is new on a chat board or forum).
It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
小題1:What does the underlined word “acronyms” mean?
A．網(wǎng)友B．聊天室C．首字母縮寫詞D．關(guān)鍵詞
小題2:Why do people type acronyms?
A．To show their feelings.
B．Because people can type them quickly.
C．In this way newbie’s won’t understand them.
D．To make people use Internet
小題3:What does “BTW, my puter is not working well. :- ( ” mean ?
A．The person is angry at somebody.
B．The person is happy about getting a new computer
C．The person is sad that his computer is having problems.
D．The person is joking that his computer is having problems.
小題4:E-talk will probably _______.
A．keep changing
B．be easy by people on the telephone
C．be used by people on the telephone
D．make life easier
小題5:What’s the best title for this passage?

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 (大氣現(xiàn)象) known as the jet stream (氣流). 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.
小題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.
小題2:The underlined word “shoot” in the 2nd paragraph means “_________”.
A．send for B．move quicklyC．come out D．grow quickly
小題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
小題4:Where can we read this passage?
A．In a research paper. B．In a short story.
C．In a travel magazine.D．In a student’s book

In recent years advances in medical technology have made it possible for people to live longer than in the past . New medicines and machines are developing every day to extend life. However, some people , including some doctors, are not in favor of these life extending measures, and they say that people should have the right（權(quán)利）to die when they want. They say that the quality of life is as important as life itself, and that people should not be forced to go on living when conditions of life have become unbearable . They say that people should be allowed to die with dignity（尊嚴(yán)）and to decide when they want to die.

In every school there is “top” crowd that sets the pace, while the others follow their lead. For example, if the crowd decides that it is smart to wear bright red sweaters, then very soon everybody is wearing bright red sweaters.
There is nothing wrong with that, except the fact that for some people bright red sweater is really unsuitable.
The situation can even become dangerous, if the top crowd decides that it is smart to drink and to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the slaughter(屠殺).
Now it’s possible that you have come across situations like these more than once in your life. In fact you probably did something you knew to be wrong one time or another. You may have excused yourself by saying, “ Gee, the crowd does it.” Well, let the crowd do it, but don’t do it yourself. Learn to say “No”.
Develop your own standards(標(biāo)準(zhǔn))and your own judgment. If you know the crowd is planning something you disagree to, you’d better take the courage to bow out in a polite way. You’ll have the satisfaction of standing on your own two feet.
