Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle.
There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(凝結(jié)). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes, and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle(水坑) or pond in a mist(薄霧) above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It continues even if snow or hail(冰雹) fall instead because both eventually melt to form water. The amount of water vapour in the air depends on the temperature. The air is more moist(潮濕) in the tropics(熱帶) than in the cold polar regions.
小題1: What is the main idea of the passage?
A．Water cycle.B．Water vapour.
C．How rain forms. D．Water, vapour, rain.
小題2:How many ways of the water returning to the air are discussed in the text?

A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. All computer viruses are manmade. Here are some virus prevention tips.
Do not open any files attached to an e-mail from an unknown, suspicious or untrustworthy source.
Do not open any files attached to an e-mail unless you know what it is, even if it appears to come from a dear friend or someone you know. Some viruses can replicate（復(fù)制） themselves and spread through e-mail. Better be safe that sorry and confirm that they really sent it .
Do not open any files attached to an e-mail if the subject line is questionable or unexpected. If the need to do so is there always save the file to your hard drive before doing so.
Delete chain e-mails and junk e-mail. Do not forward（轉(zhuǎn)寄） or reply to any of them. These types of e-mail are considered spam（垃圾郵件）, which contains lots of annoying advertisements and useless information.
Do not download any files from strangers.
Be careful when downloading files from the Internet. Ensure that the source is a legitimate（合法的）and reputable one. Verify（證實）that an anti-virus program checks the files on the download site. If you are uncertain, don’t download the file at all or download the file to a floppy（軟盤）and test it with your own anti-virus software.
Update your anti-virus software regularly. Over 500 viruses are discovered each month, so you’ll want to be protected. These updates should be at least the products virus signature files. You may also need to update the product’s scanning engine as well.
Back up（備份） your files on a regular basis. If a virus destroys your files, at least you can replace them with your backup copy. You should store your backup copy in a separate location from your work files, one that is preferably not on your computer.

Recently I was invited to a friend’s house for supper—and had a meal I have never had before.
All the friends invited were a little surprised. It’s not that Ben is unsociable, or a bad cook, but it’s just that he never 21more than he has to. So how come he was inviting us round for a meal? Had he bought something 22for his friends? He greeted us at the door and showed us into his dining room where a 23_ -table was waiting for us.“Nothing but the best for my friends!”said Ben. We all sat down and looked 24 at each other—what was he up to?
Ben returned with four bowls of hot soup.“It’s a mixture of carrots, potatoes and tomatoes,”said Ben. The next 25was also a little strange in that we didn’t quite know what it was again. It’s just another mixture of vegetable.
As we ate we chatted and finally the 26 turned back to what we were eating.“Was there a recipe(食譜) for this,”asked Marina,“or did you 27 it up?”Ben put his fork down.“What I cooked depended on what I could find.”Marina was surprised.“But you can find anything in supermarkets these days.”“But there’s 28 choice in what you can find outside supermarkets,”he replied.
Seeing that we had all finished the food, Ben decided to tell the truth. He had read recently that supermarkets usually throw away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of __29, boxes of throw-away vegetables and fruit.
So Ben had successfully provided a decent(體面的) meal for his friends, and made us aware of the fact that there are many poor people who need the food, but the amount of food thrown away is enough to 30 millions of people.

The global energy crisis is approaching. What can we do? Here are some steps you can take.
Cooling puts the greatest stress on your summer energy bill and the power grid(電網(wǎng)). Just as t tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replaces filters monthly or as needed.
For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Raton. (SEER)
Use energy-efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat(恒溫器) and cut costs. Ceiling fans cool people, not rooms, so before you leave; turn off the ceiling fan.
Let a programmable thermostat! “remember for you” to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.
Gut your air conditioning load, and reduce pollution by planting planting leafy trees around your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs(熒光燈), which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs(白熾燈).
Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 mils per gallon to one that gets 30 mpg will save you more than ￡65 per year.
Carpool. The average U.S. commuter(乘車上班族) could save about ￡260 a year by sharing cars twice a week with two people in a car that gets 20.1 mpg---assuming the three passengers share the cost of gas.
小題1:According to the passage, the thermostat is used to ______.
A．make rooms quieterB．control room temperature
C．turn off the air conditionerD．reduce room air pollution
小題2:We can conclude from the passage that the author probably discourages ______.
A．planting leafy trees around your home
B．turning off the ceiling fan before you leave your house
C．keeping your south-facing windows open during the day
D．using fluorescent bulbs instead of incandescent bulbs
小題3:According to the passage, you can save fuel by ______.
A．using energy-efficient ceiling fansB．sharing cars with others on workdays
C．turning off everything not in useD．reducing 10% of your car trips every year
小題4:This passage is mainly about ______.
A．energy-saving tipsB．fuel-saving tips
C．do-it-yourself tipsD．environment-protecting tips

“Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American’s exports soon after it went on the air in New York in 1969.
In the United States more than six million children watch the program regularly. The viewers include more than half the nation’s pre-school children, from every kind of economic(經(jīng)濟(jì)的), racial(種族的), and geographical group.
Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.
Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional(偶然的) viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.
The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.
Why has “Sesame Street” been so much more successful than other children’s shows? Many reasons have been suggested. People mention the educational theories(理論) of its creators, the support by the government and private(私人的) businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.
小題1:“Sesame Street” is actually _______.
A．a(chǎn) street in the US B．a(chǎn) program for children
C．a(chǎn) program for teachersD．a(chǎn) program for students
小題2:Children who often watch the program _______.
A．can have problems in school
B．will find it a great help
C．will take no interest in their studies
D．will be well educated
小題3: What is special about the program?
A．It offers great fun.
B．It makes children feel able to learn.
C．It is shown at different hours during the week.
D．Children learn and enjoy themselves while watching.
小題4: Why is “Sesame Street” so popular in the world?
A．Because it is supported by the government and businesses.
B．Because it uses a variety of skillful tricks.
C．Because mothers watch it along with their children.
D．Because it makes every child watching it feel able to learn.
小題5:The best title for this passage can be _______.
A．TV ProgramsB．Educating Children
C．Sesame StreetD．A Great Success

Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks—we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遺傳學(xué)). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta. Georgia. People in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.
小題1:Ray Birdwhistell believes that physical appearance _______.
A．has little to do with culture
B．has much to do with culture
C．is ever changing
D．is different from place to place
小題2:According to the passage, the final mouth shape is formed _______.
A．before birthB．a(chǎn)s soon as one’s teeth are newly set
C．sometime after new teeth are setD．a(chǎn)round 15 years old
小題3:Ray Birdwhistell can tell what area of the United States a person is from by _______.
A．how much he or she laughsB．how he or she raises his or her eyebrows
C．what he or she likes bestD．the way he or she talks

Reading to oneself is a modern activity which was almost unknown to the learned in the early days of the history, while during the fifteenth century the term “reading” undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become popular.
One should be careful, however, of supposing that silent reading came about simply because reading aloud is distraction（分散注意力）to others. Examination of reasons connected with the historical development of silent reading shows that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character.
The last century saw a gradual increase in literacy（讀寫能力）and thus in the number of readers. As readers increased, so the number of listeners dropped, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the popularity of reading as a private activity in such public places as libraries, trains and offices, where reading aloud would disturb other readers in a way.  
Towards the end of the century there was still heated argument over whether books should be used for information or treated respectfully, and over whether the reading of material such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its advantages are, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and magazines for a specialized readership on the other.
By the end of t he century students were being advised to have some new ideas of books and to use skills in reading them which were not proper, if not impossible, for the oral reader. The social, cultural, and technological developments in the century had greatly changed what the term “reading” referred to.
小題1:Why was reading aloud common before the nineteenth century?
A．Because silent reading had not been discovered.
B．Because there were few places for private reading.
C．Because few people could read for themselves.
D．Because people depended on reading for enjoyment.
小題2:The development of silent reading during the nineteenth century showed_______.
A．a(chǎn) change in the position of literate people
B．a(chǎn) change in the nature of reading
C．a(chǎn)n increase in the number of books
D．a(chǎn)n increase in the average age of readers
小題3: Educationalists are still arguing about__________.
A．the importance of silent reading
B．the amount of information provided by books and newspapers
C．the effects of reading on health
D．the value of different types of reading material
小題4:What is the writer of this passage attempting to do?
A．To explain how present day reading habits developed.
B．To change people’s way to read.
C．To show how reading methods have improved.
D．To encourage the growth of reading.

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陳代謝) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (監(jiān)控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的衛(wèi)星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
9. European researchers are conducting hibernation experiments to ________.
A. ensure astronauts to get a complete sleep  B. find the secret of some creatures
C. make preparations for the journey to Jupiter’s moon Callisto
D. know if man can sleep for years
10. The sentence “What seems like science fiction is not completely unlikely” means ________.
A. Science fiction is people’s imagination.
B. Science fiction is imaginative, but it can be realized.
C. Things seem impossible may come true.
D. Things described in science fiction are sure to become true.
11. The passage is implied but doesn’t states that ________.
A. putting living cells into a sleep-like state is full of failure
B. Biggiogera is confident with the experiment
C. human’s hibernation needs no energy
D. medical research is the key to space flight hibernation system
12. By designing a suitable protective shelter, astronauts can ________.
A. have a good hibernation        B. lessen the pressure of traveling in space
C. feed themselves in spaceship    D. moinitor their body changes
13. What’s the best title for the passage?
A. Six humans to fly to Callisto  B. Human hibernation improves health
C. Space travel attracts people   D. Deep sleep for deep space travel
