When you look at the sky at night, the moon looks bigger than the stars. Actually, the moon is much smaller than the stars and the sun. It’s much smaller than the earth. But the moon is much closer to us than any star. That is why it looks so big. If you hold a coin close to your eye, it looks big. If you look at it across the moon, it looks small.
The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star. It takes _______ for the moon to go around the earth.
| A．more than a week | B．nearly a month | C．half a year | D．more than a year |
The moon is bright because _______.
| A．there is some fire on it | B．it is near the sun, too |
| C．there is a big mirror on it | D．it can get light from the sun |
The passage tells us _______.
| A．the sun is not the biggest star | B．the sun is bigger than any other star |
| C．only the sun can shine | D．the sun is one of the farthest stars to us |
Why do we call the sun "a life giving star"?
| A．Because it gives us warmth. |
| B．Because there are some living things on it. |
| C．Because plants and animals can’t live without it. |
| D．Because people have to live in the dark without it. |
We live in the computer age. People use computers to do much of their work. But few people know how to look after them. Remember the following when you use your computer:
1.Keep your computer in a cool, dry room. Too much or too little heat is bad for computers. Damp(潮湿) is also bad for them.
2.Do not let people smoke near your computer. Smoke of all kinds is very bad for many parts of a computer.
3.Do not eat or drink when you are near your computer. Pieces of food and a little water in the keyboard are also bad for a computer.
4.Keep your screen clean and do not have it too bright. They are bad for your eyes. Make sure the screen is not too far from or too near your eyes. Some people use different glasses to protect their eyes when they use a computer.Computers can people to do a lot of work.

For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature— what people are (41) with— that decides what they will be like? (42) is it nurture —what(43) to people when they are born —that decides what they will be like?
Scientists have been studying twins to (44) if they can find the answer, because twins start out with the (45) DNA. Sometimes twins don’t live together at birth and grow up in different (46) and different places— so the nature is the same for both, but the nurture is different.
When scientists (47) these twins in their later life, they some times find some surprising (48).
Jim Springer and Jim Lewis were adopted（收养）by two different families at birth. They first met each other again thirty-nine years (49) and discovered they had a lot in (50). Both had been (51) twice. Their first wives were both named Linda and their second wives were both named Betty!
Each twin had a son — one called his son James Alan and the (52) called his son James Alan, too. Their children each had a dog called “Toy”. They even arrived at their first (53) in the same color of car.
So far twin (54) seem to show that both nature and nurture are important. What we have from birth, and how and where we live help to build (55) we are.

We have always been warned of the dangers of forest fires. They cause _____ 85 _____ to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be _____86_____ for a forest? People start some of the fires with a special reason to actually do good to the eco-system.
In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can _____87_____ some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
Some trees even need fires to grow. These trees hold their seeds (种子) inside. Heat from a fire allows the coat of the seeds to open up. Then the seeds fall to the ground and have the _____88____ to grow/
Scientist, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or _____89_____ a after forest fires, they can go hungry _____90_____ their food has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This _____91_____ makes an eco-system.
So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

Zhalong is a nature reserve in Heilongjiang in north-east China. It is one of the world’s most important wetlands. The reserve covers an area of 210,000 hectares. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.
Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.
Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.
Every year, a lot of tourists go to Zhalong to watch birds. This year, members of our Bird-watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.
We _______ once a year. We are now inviting secondary school students to help. We need more people to help us count and do something to help the birds.
Many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife. What does the underlined word “ideal” mean?
| A．Perfect. | B．Dangerous. | C．Crowded. | D．Expensive. |

Most animals protect(保护) their young until they are old enough to take care of themselves. A fish that swims in the rivers of South America protects its young in a very strange way. This fish, a kind of catfish, uses its mouth to keep its babies from danger(危险).
When this catfish lays(产卵) its eggs, it carries them in its mouth. From what we know, it does not eat during this time. After the eggs hatch(孵化), the fish swims with its young to protect them. It opens its mouth when danger appears(出现), and the tiny fish swim inside. They swim out only when it’s safe again.
These catfish may have a peculiar way to protect their young, but it seems(好像) to work.The best title(标题) is _____________.
| A．Staying Away From Danger | B．How A Fish Protect Its Young |
| C．Laying Eggs | D．A Cat That Swims |
The catfish in the story live in _________________.
| A．lakes | B．the sea | C．rivers | D．North America |

Forests have always been useful and important to men who make use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from the terrible heat. They’re also useful in preventing(阻止) good and rich top soil from being washed away during heavy rains. If there were no forests, heavy rains would wash away the rich surface(表层) soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but men in the past had no enough knowledge about science of nature, and they cut down too many trees in the area where they lived and never planted new ones. By and by, the rich surface soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.
根据短文内容，判断正（T）误（F）。
1.Trees are not serving man everywhere.
2.Without trees it would be possible to build houses, boats, bridges and so on.
3.Trees can stop man from the terrible heat.

Now satellites(卫星)are helping to forecast(预报)the weather. They are in space and they can reach any part of the world.The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成)。They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures,the meteor- ologists compare(比较)them with earlier ones. Peerhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change,too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon,perhaps , they may be ablet to forecast the weather for a week or more ahead(提前)Satellites travel__________.
A in space B in the atmosphere
C above the ground D above spaceWhy do we use the weather satellites to take pictures of the atmosphere? Because___________.
A the weather satellites can do it easily
B clouds form there
C the weather forms there
D the pictures can forecast the weather Meteorologists forecast the weather________.
A when they have received satellite pictures
B after they have compared new satellite pictures with earlier ones
C before they receive satellite pictures
D while they study satellite picturesMaybe we’ll soon be able to forecast the weather for _______.
A one day B two days C five days D seven days or even longerThe main idea of this passage is that satellite are now used in______.
A taking pictures of the atmosphere
B receiving pictures of the atmosphere
C doing other work in many ways
D weather forecasting

Have you ever seen snow? Many people in the world have not. Some countries never have snow; some have only a little on the tops of very high mountains. In the north of England, there is quite a lot of snow every winter, but in the south of England, there is usually little.
When a student from a warm country comes to England in autumn for the first time, he feels cold at first. There are often dark clouds, grey sky and cold rain in England in autumn, and most students from warm countries do not like this.
But snow is different. Though it is cold, it is also beautiful. Perhaps, after several dark mornings, the student wakes up one day, and there is a lot of light in his room. He thinks “Is it so late?” and jumps out of bed. But no, it is not very late. He looks out of the window and there is the snow on the ground and on the houses and everywhere. The light of his room comes from clean, beautiful snow.In which part of England is there much snow in winter?
| A．In the east. | B．In the north. |
| C．In the west. | D．In the south. |
In the autumn of England, we can NOT often see __________.
| A．grey sky | B．dark clouds |
| C．strong winds | D．cold rain |
Why does the student ask himself “Is it so late?”
| A．Because he has some work to do. |
| B．Because it is bright in the room. |
| C．Because it is really late. |
| D．Because he usually gets up early. |

Can plant eat people? Probably not. But there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat- eating plant is the Venus flytrap(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(苍蝇) touches one of the hairs, the leaf closes very quickly. Then the fly can’t go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things, especially nitrogen(氮). Animal meat has a lot of nitrogen. So some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea.
根据短文内容判断。
1. The Venus flytrap grows in wet parts of the United States.
2. The Venus flytrap is a kind of plant.
3. The underlined word “presses” probably means（挤、压） in Chinese.
4. In the world, many animals eat plants but plants never eat animals.
5. From the passage, we know that not only animals eat plants, but also some plants eat animals.
Do you know why you sleep? You may think it’s because you’re tired. Or perhaps you’ve been told sleep is good for you. Yet no one knows exactly why or how people sleep.
Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers’ eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers’ eyes did not move he called non-REM sleep.
Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers’ pulses（脉搏）went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don’t know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day’s garbage.
One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest.During REM sleep, a person’s breathing and heartbeat ________.
| A．stop | B．increase | C．decrease | D．stay the same |
Which word in paragraph（段落）3 means “colorful and lively”?
| A．easier | B．empty | C．vivid | D．quickly |
Which paragraph tells what happens when people don’t get enough sleep?
| A．1 | B．2 | C．3 | D．4 |
What is the main idea of the article?
| A．REM sleep helps the brain grow. |
| B．REM sleep has been watched and recorded by scientists. |
| C．REM sleep is a time to empty the day’s garbage. |
| D．REM sleep is an active time when the body is hard at work. |
You can decide from the article that REM sleep ________.
| A．has a restful effect on people |
| B．can be avoided with lots of sleep |
| C．is something that all people experience |
| D．is something that all scientists agree on |
What makes 15,000 men and women run for hours, and what makes them run through the streets on a cold day without coats? I was one of those runners. The race is called marathon (马拉松).
I had never run more than eight miles before, and here I was training. Since the race is in April, I had to run throughout the winter, and in Boston, winters are cold. For most people, just putting on their shirts, sweaters, jackets, and hats is exercise enough. I found myself out on the dark streets, running along ice sidewalks (人行道). Even in gloves, my fingers got so cold that they looked like red carrots. My nose didn’t get warm until lunchtime !
Finally, the big day arrived. The weather was cold, with ice and rain. Bang! The gun sounded, and we started. I didn’t go anywhere at first because I was standing behind so many people. I had to wait for them to move.
At first, the running was easy. The other runners just seemed to pull me along. Somewhere around the 20-mile mark I even said to myself, "This is nothing, why did I train so hard?"
Then I hit "the wall". "The wall" is what marathon runners call the special point. I knew my body reached the point and I thought I couldn’t go any more. I was out of breath and my legs turned into pieces of wood. I was almost falling down. I can’t remember anything about the last five miles of the race.
I kept running though. At last, I heard a voice at the finishing line.
"You look good," my friend Ted said. "How did it feel?"
"Wonderful !" I replied.
For everything, if you devote yourself into it, there will be a way. I finished the race, at least, in my heart, I was the winner.Which one best describes the weather on the race day?
| A．Cold and rainy. | B．Cold and sunny. | C．Dry and cloudy. | D．Wet and foggy. |
How did the writer feel about the race during the first 20 miles?
| A．Difficult. | B．Boring. | C．Easy. | D．Interesting. |
According to the article, what must someone do to prepare for a marathon?
| A．One must eat certain food and get plenty of sleep. |
| B．One must be willing to eat, sleep, and train twenty-four hours a day. |
| C．One must run along ice sidewalks every day. |
| D．One must be willing to train a lot and doesn’t give up easily. |
Then I hit "the wall". What do you think "hit the wall" means here?
| A．撞击墙壁 | B．到达极限 | C．抵达终点 | D．中途加速 |
Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.From the passage we learn that locusts________.
| A．are small animals | B．are easily found by birds |
| C．are dangerous to their enemies | D．change their colors to protect themselves |
How can pests with different colors from plants keep out of danger?
| A．They run away quickly. | B．They have the colors much like their enemies. |
| C．They hide themselves by day and appear at night. | D．They have to move quietly. |
Bears and lions can keep safe because _________.
| A．they have the colors much like the trees | B．they move quietly |
| C．they like brown and gray colors | D．they live in forests |
Why can the kind of fish live up to now?
| A．Because it is very and strong. |
| B．Because the liquid it sends out can help it escape from its enemies. |
| C．Because the liquid it sends out can kill its enemies. |
| D．Because it swims faster than any other fish. |
