No two clouds are ever alike. But it is still possible to group clouds and to give them names. We can recognize the different kinds of clouds and watch them for signs of changing weather.
As a rule, the higher the clouds, the better the weather. And the lower the clouds, the worse the weather is likely to be. To predict the weather, there are three things about clouds you should look for: movement, color, and change.
Clouds can tell you if storm is on the way. For example, small feathery cirrus clouds (卷云) can become thick and move lower. This means rain is on the way. If there is a sudden, cool breeze (微风) thunder (雷声) clouds appears, then a storm is about to break out.
According to the first paragraph, we can say that ______.
A．the weather always remains the same in a day
B．a fine day can't last for long
C．we rarely think about the weather
D．the weather changes a lot
Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A．have too many conflicting theories
B．do not have enough funding to continue our research
C．are not sure how the universe is put together
D．have focused on investigations of the moon and planets

"If your computer is down, just write me out a ticket."
"I can't write you out a ticket. The computer is the only one allowed to do so."
I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do？'
"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."
"So when it goes down, you go down with it."
"That's good, sir. '
"How long will the computer be down？" I wanted to know.
"I have no idea. There's no way we can find out without asking the computer."
After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes？ They're still flying, aren't they？"
"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.
By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people started to cry and still others kicked their luggage.
The best title for the article is______.
A．When the Computer Is Down

We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.
The way to stop wasting our limited water is to （）.
A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater
