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.

A．are small animals	B．are easily found by birds

【小题4】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.

Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮丧) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
【小题1】The purpose of Beck and Edwards’ study is to _____________.

A．understand human-animal relationship

B．make lonely old people’s life better

C．find the causes of old people’s loneliness

D．improve the animal-assisted research

【小题2】 In the research, the old people are asked to _____________.

A．note the activities of AIBOs

B．keep AIBOs at home for 12 weeks

C．record their feelings and activity

D．study the collected information

【小题3】What does the underlined word “removes” mean?

【小题4】What is the better point of AIBO than live dogs?

A．It is easier to keep at home.

B．It can help the disabled people.

C．It responds to all the human orders.

D．It can watch TV with its owner.

【小题5】The writer seems to suggest that the future robotic dogs may__________.

A．cure certain diseases	B．keep old people active
C．change people’s ideas	D．look more like real dogs

I’m taking my family to other countries to have a trip. My wife and I and our two children are all going along. My elder brother will go with us, too. He has never been overseas and he is even more excited than the children. My father is so old that he’d like to stay at home and take care of the house.
We’re going by train to New York, and then take a ship to Europe . When we arrive in Europe, we’re going to some countries for sightseeing (观光). We’ll go to places either by train or by bus. We’re going to fly home.
It took us a long time to decide where to go, but I think we’ll have a very interesting trip. We’ll go to England, France and Italy. We also talked about how we would go to Europe. At first we wanted to fly because it would be faster and would save more time. But my brother likes to take a boat trip and the children like that, too.
(    ) 1. How many people will go to have a trip?
A. Three          B. Four         C. Five             D. Six
(    ) 2. My father will not go on the trip because               .

Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.
Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees) . Trees soak up carbon dioxide, one of the greenhouse gases, from the air.
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that is disappearing because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.
Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (联邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do.
Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.
