Oil is so important that it is sometimes called “black gold”. Almost half of our energy comes from oil. We use it to run our cars and factories and to heat our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you wash your hands with might also be made from oil. Your favorite plastic toy is made from oil.
Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked（渗漏）out of the ground. Today, however, we have many ways of finding oil. One tool measures（测量）the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves（声波）. Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them.
We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this “black gold”.
小题1:Which of the following isn’t the way to help find oil?

A．Sound waves travel through different kinds of rocks at different speeds.

B．People measure the pull of gravity to know if there is oil.

C．Sound waves tell us where the oil has leaked out of the ground.

D．People know there is oil if it leaks out of the ground.

小题2:Which of the following does the passage lead you to believe?

A．Oil was firstly found by measuring gravity.

B．Many things are made from oil.

C．We will never run out of oil.

D．Our lives would not be different if we didn’t have oil.

小题3:The main idea of the whole story is that ________________.

A．many things are made from oil

B．we must find new ways of looking for oil

C．people spend a lot of time looking for oil

D．oil is important for us but hard to find

Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.
Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.
The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.
We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.
Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳).
It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.

Scientists have found a new use for children’s imaginations(想象力)—to make Stomachaches go away.
The BBC reports a new study that shows: “Children can be taught to use their Imaginations to deal with stomachaches.” This may be very good news for parents who need a quick cure for their sick children.
Any mother or father understands the stomach problem is one of the most frequent(时常发生的) things their children complain about. Around twenty percent of children suffer from stomachaches that doctors cannot find a reason for.
This new research is especially good for kids with active imaginations. Researchers found that the more creative the child is, the better he or she is at imagining the pain away.
The researchers used a relaxing CD with children. A voice guided them through different fantasy(幻想) situations. One of these was pretending to be floating on a cloud. Thirty children took part in the tests. Half of them used the “guided imagery” method, and the other half received normal medicines. Researchers found 73.3 percent of the CD users reported a reduction in pain. This compared to only 26.7 percent of kids who got normal treatment.
Study leader Dr Miranda Tilburg was very excited about her findings. She believed that it was a very cheap and easy way to stop children’s stomachaches. She said it would not work as well with adults.
小题1:The new study may be good news for those who____________.

A．have less imaginations

B．don’t know how to relax

C．want to stop their kids’ stomachaches in a short time

D．can find why children suffer from stomachaches

小题2:What kind of kids will benefit most from the new research?

A．Kids who like listening to music.

B．Kids who are good at remembering things.

C．The independent(独立的) kids.

D．Kids with active imaginations.

小题3:From the end of the passage, we know that__________.

A．adults can also use their imaginations to make stomachaches go away

B．Dr Miranda Tilburg wasn’t pleased with her findings

C．the normal cure for stomachaches will not be used

D．a cheap and easy way to stop children’s stomachaches has been found

小题4:What is the best title for this passage?

A．How to stop stomachaches in public places.

B．Children can “imagine” their pain away.

C．Children’s imaginations are very active.

D．How to develop children’s imaginations.

Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.
Beginning in the middle of the 20^th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.
So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.
By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.
So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.
小题1:Which problem is NOT talked about in Paragraph 2?

A．Water

B．Air

C．Lifestyle

D．Food

小题2: The underlined word ‘scarce’ means ‘______’ in Chinese.

A．昂贵的

B．充足的

C．缺乏的

D．特殊的

小题3:Which of the following is NOT true?

A．Only a few people changed their lifestyle in the 20^th century.

B．There was no clean water for people to drink by the year 2200.

C．All the fish died because of the pollution by the year 2300.

D．We found a new home in another planet by the year 2400.

小题4:What’s the best title of the passage?

A．Stop polluting	B．Change or leave
C．Look for new home	D．Return to the earth
