答案
小题1:C
小题2:B
小题3:D
小题4:D
解析
小题1:细节理解题。从图片中可以看出，共有三个实验。
小题2:综合理解题。通过认真看图分析，可以得知。实验A的第二步是倒出一些水，以便于有形成云的足够的空间；实验B的第二步是把瓶子放在热水中，以便于使瓶中的空气遇热上升进入气球；实验C的第二步是把气球放在瓶子上。
小题3:细节理解题。从实验A的第④步“…there is a cloud”可以看出瓶中产生了云，当然里面还有原来的水。
小题4:推理判断题。因为“cold air falls”可知，瓶中的空气遇冷要下降，气球也随之下降进入瓶中。

1. Where are the rainforests?
Rainforests cover six per cent of the Earth’s surface. There are rainforests in many parts of the world but the biggest forests are in South America, Africa and South East Asia. There aren’t any rainforests in Europe or North America.
2. What’s in the rainforests?
About 75% of all the types of animals that we know come from rainforests. Thousands and thousands of animals live in rainforests. There are many very beautiful birds, insects and reptiles. Many of them live in the trees, more than 30 metres from the ground. There are also thousands of different plants—and lots of tall trees! It is always hot in a rainforest and
the ground is always wet. It is also dark.
3. Why are the rainforests important?
The rainforests are very important for us. We need them! The trees and other plants in the forest help to make the air that we breathe. They give us wood, rubber, fruits and many of our medicines.
4.
Unfortunately, in many places, the rainforests are in danger. For example, many years ago there was a large rainforest in Java. There were thousands of different plants and animals in the forest, but now there is nothing. People chopped down the trees because they wanted to grow rice. Many animals lived in the rainforest. Some of them went to other parts of Java but many of them disappeared — forever. The same thing is happening now in many other parts of the world. The rainforests are in danger.
小题1:In which of the following places can we find rainforests according to Paragraph 1?
A. In the UK. B. In Asia. C. In the USA. D. In France.
小题2:Which of the following belongs to a kind of “reptile”?
| A．A sparrow. | B．A swallow. | C．A snake. | D．A butterfly. |
| A．What’s happening to the rainforests? |
| B．What can we find in the rainforests in Java? |
| C．Why did people chop down the trees in the rainforests? |
| D．Why did many plants and animals disappear in the rainforests? |
| A．To tell us how to survive in the rainforests. |
| B．To help us know some living things in the rainforests. |
| C．To tell us to care about the protection of the rainforests. |
| D．To give us advice on how to make full use of the rainforests. |
"She was wearing a fashionable coat. His shirt was really a fashionable colour. "
But of course there are fashions in many things, not only in clothes. There are fashions in holidays, in restaurants, in films and books. There are even fashions in school subjects, jobs ... and in languages.
Fashions change as time goes. If you look at pictures of people or things from the past, you will see that fashions have always changed. An English house of 1750 was different from one of 1650. A fashionable man in 1780 looked very different from his grandson in 1860.
Today fashions change very quickly. Some of this is natural. We hear about things much more quickly than in the past. Newspapers, radios, telephones and television send information from one country to another in a few hours.
New fashions mean that people will buy new things, so you see there is money in fashion.
小题1:Most people think that "fashion" means __________.
| A．subjects | B．holidays | C．books | D．clothes |
| A．finding a job |
| B．looking at pictures |
| C．eating in a restaurant |
| D．wearing a fashionable coat |
| A．three | B．four | C．five | D．six |
| A．people like fashion and money |
| B．fashionable things are expensive |
| C．one can make money through fashion |
| D．a fashionable man makes much money |
| A．the changes of fashions |

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 brain is working day and night. If you learn words before bed, a certain part of your 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(按钮)” in the human brain. It might make a person more talented(有才能的).
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 your brain “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.

| B．Our brains need much energy every day. |
| C．Smoking can keep our brains healthy. |
| D．Getting exercise is good for our brains. |
Perhaps(可能) you have heard of Henry Ford. He first started making cars in large numbers. Perhaps he didn"t know how much the car was going to be to American culture(文化). The car made the United States a nation on wheels(车轮). And it helped make the United States what it is now.

When compared to twoparent families, singleparent families are usually at a disadvantage in some ways. They are often in short of money, and children receive less attention. What’s more, single parents can find themselves under too much pressure(压力) of both work and home. Despite(尽管) these disadvantages, it is possible for singleparent families to look for support from friends, schools, communities or other organizations. They need to remember that nobody can do it alone.
Surprisingly, singleparent families also have some advantages over twoparent families. Single parents have greater flexibility(灵活性) in spending time with children, because they don’t have to consider the needs of a husband or wife. So they can develop closer relationships with their children. Another advantage comes from the fact that single parents often work together with their children to solve problems, which makes children feel more needed and valued.
It’s important to remember that singleparent families have, until now suffered prejudices from some people. They think that it’s easier for the children in singleparent families to drop out of school in teens, and to be jobless in their early twenties. But, with the support from friends, schools and communities, singleparent families become more accepted by society, and this situation is certain to improve. In the future we will probably see these prejudices disappear.
小题1:What does the writer mainly tell us in Paragraph 1?
A. People shouldn’t have prejudices against singleparent families.
B. The singleparent family is not good for raising children.
C. The twoparent family is the correct way to raise children.
D. 50% of children will be members of a singleparent family in the USA.
小题2:Which disadvantage of singleparent families is NOT mentioned in Paragraph 2?
| A．They are often in short of money. |
| B．Children may receive less attention. |
| C．Children also suffer from the prejudice. |

| A．Don’t consider the needs of others. |
| B．Pay more attention to their children. |
| C．Develop closer relationships with their children. |
| D．Discuss and solve problems together with their children. |
