【题目】Answer the questions (根据短文内容回答问题):

Venus (金星) has long been one of the most misunderstood planets. Like the earth, Venus has its own atmosphere. However, the atmosphere is much thicker than that of the earth, which makes it difficult for modern scientists to study. There is much we still do not know about what this planet like. However, using special machines, scientists have unlocked many of the long-hidden secrets in recent years.

Venus is in many ways the earth’s sister planet. It is almost the same in size and chemistry as the earth. In other words, Venus is made up of almost the exact same types of materials as the earth, in about the same amounts.

In the early days of Venus’ 4-billion-year-old life, it would have appeared very similar to the earth. The two would have been almost the same. However, over a period of a few million years ago, Venus lies much closer to the sun than our planet. It has made Venus terribly hot.

Since it is closer to the sun, Venus’ temperature should be a little warmer than that of the earth. As the planet warmed, water which can be used to form oceans, lakes and rivers, evaporated(蒸发). This increase in water vapor(水蒸气)began a cycle of global warming. Water vapor is a very effective greenhouse gas. It caused the temperature to rise and more water to evaporate. The temperature then climbed still further. Today it is likely that all of Venus’s water has evaporated into the atmosphere. This atmosphere effectively keeps the sun’s energy and makes the surface to burn much hotter than it naturally would.

If you happen to find a way to survive the extreme heat on the surface of Venus, you will quickly notice something strange about the days. Venus rotates(旋转) very slowly, so that a day on Venus actually lasts longer than a year. Instead of the sun rising in the east and setting in the west, the sun would appear to rise in the west and set in the east when you are on Venus.

【1】Both Venus and the earth have their own atmosphere, don’t they?

_______________, _____________________________________________________.

【2】 How can the scientists finally get to know more about Venus in recent years?

_______________________________________________________________________.

【3】Why is Venus considered the earth’s sister planet?

_________________________________________________________________________.

【4】What has caused Venus to become completely different from the earth?

________________________________________________________________________.

【5】Please list some other strange natural phenomena(现象) on Venus besides the heat.

_________________________________________________________________________.

【6】In recent years, the earth faces the similar situation which makes Venus very hot. What do we call this kind of situation and what caused the problem on the earth?

_________________________________________________________________________.

【题目】As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.

Scientists have found out that the radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won’t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.

Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage(损坏).

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.

1______ shows the man-made things in space in the correct way.

A.B.C.D.

2The radiation from the sun and other stars is ______ to spacemen.

A.goodB.helpfulC.usefulD.harmful

3The underlined word “fragments”means “______”.

A.碎片B.泡沫C.烟雾D.飞碟

4The passage talks about _________ kinds of danger in space.

A.twoB.threeC.fourD.five

5Which of the following is TRUE?

A.Scientists have found out ways to solve any problem in space.

B.Every one of us can have a travel to space in ten years.

C.The harm of the radiation may be found in the spacemen’s children.

D.Space is really dangerous, so it doesn’t interest anyone on the earth.

As a child, I learnt how to make paper masks from newspapers and old magazines. Later I used coloured cardboard. Making masks seemed like a popular art activity. After we made the masks, my classmates and I would put them on and pretend to be people that we were not. By hiding our faces b 【1】 the masks, it did not seem ridiculous to pretend to be an old man or a baby. Immediately, the mask helped us to step into the shoes of a 2 character.

A mask allows a person to take on different characters, to pretend and make-believe. Have you ever w 3 what the actual face of the clown at the circus is like? The clown’s mask, with white smiling mouth and the round red cheeks, covers whatever the clown r 4 looks like.

Masks can also be used to hide what we do not want people to see. For example, the Phantom of the Opera, tells the story of a man who fell in l 5 with a beautiful woman. However, one side of his face was ugly and terrible to show anyone. Thus, he wore a mask to hide that part of his face.

Adults, more than children wear different masks every day. These are not actual masks like the types that are made in art classes in schools. These masks refer to the person’s ability to hide his real thoughts and feelings. He will behave in different ways no matter what he is actually feeling i6 . Sometimes, we will put on a happy face even though we are s 7 . We wear masks because we do not want people whom we do not know well to know what we are actually thinking and feeling.
