As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won’t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.
Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage(损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.
______ shows the man-made things in space in the correct way.
A. | B. | C. | D. |
The radiation from the sun and other stars is ______ to spacemen.
A.good | B.helpful | C.useful | D.harmful |
The underlined word “fragments”means “______”.
A.碎片 | B.泡沫 | C.烟雾 | D.飞碟 |
The passage talks about _________ kinds of danger in space.
A.two | B.three | C.four | D.five |
Which of the following is TRUE?
A.Scientists have found out ways to solve any problem in space. |
B.Every one of us can have a travel to space in ten years. |
C.The harm of the radiation may be found in the spacemen’s children. |
D.Space is really dangerous, so it doesn’t interest anyone on the earth. |
What does it feel like to break a bone (骨头)? It’s different for everyone, but the pain is often sharp (严重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (钢钉) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
Your bones are excellent at healing themselves. Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
Which of the following is the best title for the passage?
A.How to Know if a Bone is Broken |
B.How Broken Bones Heal Themselves |
C.Common Causes (原因) of Broken Bones |
D.What You Should Know about Broken Bones |
When someone breaks his bone, the following should be done except ______.
A.asking the doctor for help | B.comforting the hurt person |
C.moving the injured part | D.staying calm |
Which is the correct order to treat the break?
a. take an x-ray b. use metal pins to set it c. put it back to its normal place d. put on cast
A.a→b→c→d | B.a→c→b→d | C.a→d→c→b | D.d→a→b→c |
The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.
A.break again | B.become worse | C.wound or hurt | D.become healthy again |
Where would you probably read this passage?
A.In a story book. | B.On a poster. | C.In a health care book. | D.In a chemistry book. |
Every time you turn on the television or take a ride in a car ,you could be adding to a problem called acid rain(酸雨). In this article, you’ll learn how acid is created, and how it affects us, and more importantly, what we all can do to prevent it.
How is acid rain created?
When people use fuels(燃料), such as coal and gasoline, poisonous gases are give off. When these gases mix with rain, acid rain forms. Many power stations burn fuels in order to creat the electricity(电) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline .When rain mixes with these gases, harmful things called acids form. This is acid rain.
How does acid rain affect us?
Acid rain damages(毁坏)everything that it touches. It poisons our rivers, ponds, lakes, and oceans along with all the life in them. It pollutes our soil and crops, harms trees, and can even kill fish and plants. Acid rain also eats away at buildings.
How can we prevent acid rain?
We need to cut down on the pollution that gets into our air. Turn off lights, television, and other electrical appliances if you are not using them, Walk or take a bike whenever possible. If you are travelling a long distance, take a bus or train to save fuel.
As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.
When power stations burn fuel,_______.
A.acid rain form | B.air pollution is caused |
C.noise pollution is caused | D.acid rain gets heavier |
According to the article, acid rain affects us _______.
A.suddenly | B.slightly | C.seriously | D.immediately |
What advice does the article give us?
A.Go to school on foot or by bike if we can. |
B.Go to bed earlier in order to use less electricity. |
C.Travel by bus to prevent acid rain. |
D.Turn off the television on rainy days. |
What is the best title of the article?
A.Preventing Acid Rain | B.Forming of Acid Rain |
C.Acid rain, Heavy Rain | D.Acid Rain, Killer Rain |
Tony: These days, the word “clone” has appeared very often in the newspapers. Do you know its meaning?
Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb* named Dolly from a grown-up sheep. So people call him the “father” of Dolly.
Tony: In fact, the word “clone” means to produce the “same” animal by taking cells* from a
grown-up one. I think, if we know how to do cloning, we need only to keep a small number
of sheep, cows or horses.
Lana: What’s more, these days some people even want to clone humans. They have asked: Can we
clone ourselves?
Tony: It seems interesting. But do you think it possible to do that?
Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.
Tony: Then can we clone a living person?
Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a “human”.
Tony: Well, you mean that it is not a real human.
Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning.
The word “clone” means_________________.
复制 B 克隆 C 抄袭 D 制造

Everyone has got two personalities (性格) —the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by new ideas. You don’t like to make people unhappy, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you’re always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel worried, but you don’t often get unhappy. You always say what you think, even if it makes people angry.

We need to be responsible for our environment. Being a frugal consumer(节俭的消费者) is one way to help. But, what exactly does that mean?
Use It Up
You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.
Wear It Out
You do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.
Make It Do
When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.
Do Without
Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world's resources(资源). And, getting rid of the things we don't want any more takes up even more resources and space.
Do we need to be responsible for our environment?
How do we deal with the last little piece of soap?
When do we need to get a new iPhone?
What should we do when something we want is not on hand?
What does the writer want to tell us?
My summer hols wr CWOT. B4, we usd 2 go 2 NY 2C my bro, his CF & thr 3:-@ kids FTF ILNY, its gr8.
Can you understand this sentence? If you can't, don't feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet or cellphones. To newcomers, it can look like a completely foreign language. So, what is the "translation" of the sentence above? My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love New York; it's great.
Schoolteachers and parents say this new form of writing is harming(破坏)the English language. Increasing spelling and grammatical mistakes cxan be seen in students' writing. They fear the language could become corrupted(面目全非的).
Everyone should just relax, say linguists(语言学家). They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. "People get better at writing by writing," he says, "Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents."
Linguist James Millroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today's teenagers become tomorrow's parents, they too will think this way. Milroy argues that languages do not and cannot become "corrupted"; they simply change to meet the new needs.
However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, "I can understand Netspeak worries teachers and it's important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future."
Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn't use text language in my homework. Texting is just for fun"
What is the main purpose of the first paragraph?
A.To give an example of a foreign language. |
B.To show an example of creative methods. |
C.To express worries about using Netspeak. |
D.To lead in the topic of Netspeak. |
Which of the following is true according to the passage?
A.Cynthia McVey points out teenagers can deal with Netspeak properly. |
B.Geoffrey Nunberg believes Netspeakers can write Standard English. |
C.David Crystal thinks Netspeak helps develop the habit of writing. |
D.James Milroy says that language is changing and improving. |
The expression "bet your bottom dollar" in Paragraph 5 means ______.
A.be fairly sure | B.be greatly surprised |
C.think it a pity | D.find it interesting |
What can be the best title for the passage?
A.Netspeak: A Widely-Used Language on Internet |
B.Is Netspeak Harming the English Language? |
C.Is Netspeak Helpful in Language Learning? |
D.Netspeak: Advantages and Disadvantages |
How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot.
A British scientist found out that ________ could improve our memories.
A.drink | B.dreams | C.sleep | D.bananas |
According to the passage, if we want to have a good brain, we should ________.
A.use our brains more | B.sleep fewer hours |
C.work longer hours | D.remember fewer things |
Which of the following is TRUE according to the passage?
A.Our brains only work in the daytime. |
B.Our brains need much energy every day. |
C.Smoking can keep our brains healthy. |
D.Getting exercise is good for our brains. |
Almost all of us have unpleasant habits. We all want to get rid of(摆脱) them, but we don’t know proper ways. Here’s some advice.
●Write down all the reasons why you want to stop some behavior. Look at the reasons very often.
●It’s clever to do something else when you want to stop your bad habits. If you get angry easily, for example, you can go out for a walk.
●Decide what you’ll do to reward(奖励) yourself if you really get rid of your bad habits.
●If you get too heavy, keep junk food out of your house.
●Bad habits develop over years, so you can’t get rid of them very soon. So you should be patient.
●Don’t be afraid to ask others for support. You can talk to your friends, family or other people. When you talk to them, they might be able to provide some advice that you can’t get from yourself.

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. |
What can we learn from the second paragraph?
A.All birds stay in Zhalong Nature Reserve all year round. |
B.There are eight species of red-crowned cranes in Zhalong. |
C.The number of the world’s red-crowned cranes is small. |
D.Every winter red-crowned cranes hatch eggs in Zhalong. |
Which of the following can we choose for the blank (空白) in the fifth paragraph?
A.go birdwatching | B.do a bird count | C.go bird-hunting | D.hold a bird show |
The purpose of the article is to _______.
A.attract more visitors to pay a visit to Zhalong Nature Reserve |
B.ask people to take action to protect wetlands and wildlife |
C.prevent people from watching birds in Zhalong Nature Reserve |
D.make people around the world know the Birdwatchting Club |
The building is shaking. A woman with a baby in her arms is trying to open the door, but fails. Finding no way, she rushes into her bedroom and there they survive the earthquake.
In a factory building, as the workshop floor swings under the terrible shaking, workers run for safety. Some hide(隐藏) under the machines and survive , but others who try to run outside are killed by the falling ceilings.
These scenes, played by actors and actresses, are from a film of science education 《Making a Split Second Decision》 shown in 1998 on China Central TV in memory of Tangshan Earthquake.
By studying actual cases in the earthquake areas and scientific experiments, experts(专家)find that buildings remain untouched for the first 12 seconds of an earthquake.
In this short time, one has the best chance of surviving an earthquake by staying near the inside walls, in bedrooms and under beds, experts concluded in the film. “Earthquakes seem to catch the lives of those who run,” said many survivors in the earthquake areas, describing how their friends were killed on the doorways or along the stair steps as they tried to get out of the building.
Their advice was proved in the film, “Take a hiding-place where you are rather than run, unless you are sure you can reach a safe open place in ten seconds.”
The word “survive” appears in the passage several times. It probably means in Chinese.
A.遇难 | B.幸存 | C.恐惧 | D.摇晃 |
The workers who tried to run outside the building died because .
A.the factory building was shaking terribly |
B.they were making a film |
C.they didn’t have enough time to run outside |
D.they were too nervous |
The passage suggests that you should when an earthquake happens.
A.cry for help |
B.not move and lie on the floor at once |
C.run down the steps as fast as you can |
D.find a safe place and hide in at once or run out in ten seconds |
Where can we probably find this passage?
A.In a magazine. | B.In an advertisement. | C.In a history book. | D.In a poster. |
