Water goes around and around Earth in a never ending journey called the water cycle（循环）. The sun heats up lakes, oceans, and other wet places on Earth. When the water gets warm enough, it changes into vapour. Plants also give off lots of water vapour. Some of this water vapour cools off high in the sky and becomes clouds. Then it falls back to Earth in a new place as rain or snow. This cycle happens over and over again.
The ground can absorb water like a sponge (海绵). If you could see this groundwater, it wouldn’t look like a lake or river. The groundwater is mixed in with the rocks and sand that lie in layers(层) below Earth’s surface.
Groundwater moves along slowly. How slowly? Maybe 1.5 kilometres in one century. Some of this water has been underground for thousands of years. And once groundwater is pumped out of the ground from a deep well（井） by people, it may take hundreds of years for another water to take its place.

a .Fall down as rain or snow.
b. Heated up by the sun on lakes, oceans and other wet places.
c. Cool off high in the sky.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．
1．Which of the following is NOT done by satellites according to the passage?
A．Sending information for weather forecast．
B．Taking photographs of the Earth．
C．Sending TV pictures．
D．Providing food for airplane pilots．
2．What’s the speed the earth rotates at?
A．35,880 kilometers per hour． B．335,880 kilometers per hour．
C．11,000 kilometers per hour． D．110,000 kilometers per hour
3．Why does the satellite move around the world at the same speed as the Earth rotates?
A．In order to take photographs．
B．In order to stay in a certain position in the orbit．
C．In order to move away from its orbit．
D．In order to send television pictures．
4．What does the underlined word “This” in the 3rd paragraph refer to?
A．A satellite． B．A little rocket．
C．A satellite seems to stay in the same place in the sky．
D．The satellite puts the rockets in the right position．
5．Which is true of satellites?
A．A satellite usually works for about 10-12 years．
B．Every time a satellite gets broken，it is brought back to the Earth to be repaired．
C．A broken satellite is never left in space．
D．They often crash into each other．

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
1．According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious B. it can‘t harm people’s health
C. it can lower cancer risk D. it is not taken enough every day
2．Which of the following can not help people get more Vitamin D?
A. Have some sunshine B. Have more meat
C. Have more fortified cheese D. Have a vitamin supplement
3．Who can Garland probably be?
A. A health researcher B. A doctor
C. A scientist D. A public health official
4．Which of the following food can lower people‘s chance of getting cancer?
A. Milk B. Fortified orange juice
C. Fortified yogurt D. All of the above
5．People from which area should take more Vitamin D according to the passage?
A. Asian people B. African people
C. American people D. European people

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died. w_w w. k#s5_u.c o*m

The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs. w_w*w.k*s_5_u.c*o*m
Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.
1. A greenhorn now refers to ____. w_w w. k#s5_u.c o*m

A. a person who is new in a job B. a new solider
C. a young horse D. a cow without horns
2. A person who has a green thumb is a person ____.
A. who is good at growing plants B. whose thumbs are of green color
C. whose garden is greener than others’ D. who is younger than his neighbors
3. The author is actually talking about ____. w_w w. k#s5_u.c o*m

A. colors B. language C. politics D. agriculture
4. Which of the following statements is NOT true according to the passage?
A. In about the 16th century, a greenhorn meant an experienced soldier.
B. The Green Revolution may have some connection with green thumbs.
C. The green-eyed monster was probably created by William Shakespeare.

People with disabilities make up a large part of the population. It is estimated that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental", i.e., they occur before the individual's twenty-second birthday, often from genetic conditions, and are severe enough to affect three or more areas of development, such as mobility, communication, employment, etc. Most other disabilities are considered “adventitious", i.e., accidental or caused by outside forces.
Prior to the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disabilities was unavailable. Advancements in medicine and social services have created a climate in which people with disabilities can expect to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basics are often not available. Civil liberties such as the right to vote, marry, get an education, and gain employment have historically been denied on the basis of disability.
In recent decades, the disability rights movement has been organized to fight against these infringements（违反；侵犯）of civil rights. Congress responded by passing major legislation recognizing people with disabilities as a protected class under civil rights statutes.
Still today, people with disabilities must fight to live their lives independently. It is estimated that more than half of qualified Americans with disabilities are unemployed, and a majority of those who do work are underemployed. About two-thirds live at or below the official poverty level.
Significant barriers, especially in transportation and public awareness, prevent disabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships.
Only when public attitudes advance as far as laws have will disabled people be fully able to take their rightful place in society.

1. A “developmental" disability ______.
A. develops very slowly over time
B. is caused by forces
C. occurs in youth and affects development
D. is getting more and more severe
2．Most disabled people used to die early because ______.
A. disabilities destroyed major bodily functions
B. they were not very well looked after
C. medical techniques were not available
D. they were too poor to get proper treatment
3. In the author's opinion, to enable the disabled people to take their rightful place in society, ______.
A．more laws should be passed
B．public attitudes should be changed
C．government should provide more aids
D．more public facilities should be set up
4. Which of the following cannot be inferred（推断）from the passage ?
A．Many disabled people may remain single for their whole life.
B．The public tends to look down upon the disabled people.
C．The disabled people feel inferior to those surrounding them.
D． Discriminatory laws prevent the disabled from mixing with others.
5. The best title for this passage might be ______.
A．Handicaps（不利条件；障碍；）of People with Disabilities
