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

In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In Western countries, people did not use paper money until the 15th century. However, people in China began to use paper money in the 7th century.
A Chinese man called Cai Lun invented paper almost 2000 years ago. He made it from wood. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not give enough time to grow more trees to take the place of those we use for paper.
So how can we save paper? We can use both sides of every piece of paper, especially then we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchief and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
小題1: When he was in China, Marco Polo ________.
A.saw many wonderful things
B.read a lot of books
C.discovered Cai Lun invented paper
D.learned to make paper
小題2:About ________ tons of paper are thrown away every day in our city.
A.48,000B.1,700C.2,000D.2,800
小題3:Which of the following is NOT the way of saving paper?
A.To use cotton handkerchiefs instead of paper ones.
B.To grow more trees.
C.To use both sides of very piece of paper.
D.To use the paper bags from shops more than once.
小題4:Which of the following is NOT true?
A.About 48,000 trees can be used to make 2,800 tons of paper.
B.If we keep on wasting paper, we will have no paper to use.
C.The Chinese used paper money much earlier than the people in western countries.
D.It is never too late to plant trees for paper.
小題5:Which is the best title of the passages?
A.Cotton Handkerchiefs Back Again
B.Cai Lun, the Great Inventor
C.Saving Paper
D.The history of Paper

Air is a colorless, tasteless and invisible(看不見(jiàn)的)gas that is around us. An “empty” drinking glass and an “empty” room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth(布)into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.
小題1:Since air is matter, it has ________.
A.room , and weight as wellB.both room and shape
C.either room or weightD.neither shape nor weight
小題2:The word “Stuff” means ______ in Chinese.
A.撕B.蓋C.取掉D.塞

Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world — and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first Laughter Club was started in Mumbai, India, in 1995 by Dr. Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr. Kataria, “Everyone’s naturally good at laughing. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.
So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest — I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. However, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody in the room was laughing for real — and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results!
小題1:The first Laughter Club was started in _____.
A.BritainB.AmericaC.AustraliaD.India
小題2:The writer felt _____ at the beginning of the class?
A.surprisedB.pleasedC.nervousD.stressful
小題3:The people in the club began to laugh for real _____?
A.a(chǎn)fter ten minutesB.a(chǎn)fter ten hoursC.a(chǎn)fter a few seconds D.a(chǎn)fter ten days
小題4:Which of the following is true according to the passage?
A.Fake laughter and real laughter are both good for health.
B.40% of the people in Laughter Clubs are good friends.
C.Adults laugh more often than children in a day.
D.Laughing is the best way to prevent illness.

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.
