Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren’t there many factories like the Symi factory?
In some places the sun is not hot enough. Or it does not shine every day.
In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.
One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way for each place.
Symi’s way seems very good for small, hot places. It does not make much water at a time. But the factory is easy to build and costs little.
That is why people in many dry places talk about Symi. From the passage we know that fresh water _____________.
| A．is needed in many countries | B．is needed in every country |

In a small village in England about 150 years ago, a mail coach (邮车) was standing on the street. Around the coach many people were talking to one another about it. Mail coach did not come to that village so often in those days. People had to pay a lot of money to get a letter. The person who sent the letter did not have to pay. The person who got the letter had to pay the postage (邮资). “Here?s a letter for Miss Alice Brown,” said the mailman. Everyone turned to a girl of about eighteen who was standing by the coach. “I?m Alice Brown,” she said in a low voice. The mailman gave her the letter. Alice looked at the envelope for a minute, and then handed it back to the mailman. “I’m sorry I can?t take it,” she said. “I don?t have enough money to pay the postage. ” The people standing around were very sorry for the girl. They were silent for a while. Then a gentleman came up to the mailman and paid the postage for Alice’s letter. When the gentleman gave her the letter, she said with a smile, “Oh, thank you very much, sir. This letter is from the young man I’m going to marry. His name is Tom. He went to London to look for work. He has to get enough money for our marriage (结婚). I’ve waited a long time for this letter, but now don’t need it. I don’t have to open the envelope because there is nothing inside. ” “Really?” the gentleman said in surprise. “How do you know that?” “He told me that he would put some signs on the envelope. Look, sir, this cross in the corner means that he is well, and this circle means he has found work. That’s very good news. ” The gentleman was Sir Rowland Hill. He did not forget Alice and her letter. “The postage to be paid by the receiver has to be changed,” he said to himself. He thought and thought for many years. At last he had a good plan. “The postage has to be much lower,” he said. “What about a penny (便士) for a letter? And the person who sends the letter pays the postage. He has to buy a stamp and put it on the envelope. ” “A good idea!” people said when they heard of his plan. The Government decided to adopt (采纳) the plan. The first postage stamp was put out in 1840.

Now satellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare（比较）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.Satellites travel _____________.
| A．in space | B．in the atmosphere | C．above the ground | D．above space |
Why do we use the weather satellites to take pictures of the atmosphere? Because __________.
| A．the weather satellites can do it easily |
| B．clouds form there |
| C．the weather forms there |
| D．the pictures can forecast the weather |
Meteorologists forecast the weather __________.
| A．when they have received satellite pictures |
| B．after they have compared new satellite pictures with earlier ones |
| C．before they received satellite pictures |
| D．during they study satellite pictures |
Maybe we’ll soon be able to forecast the weather for ________.
| A．one day | B．two days | C．five days | D．seven days or even longer |
The main（主要的）idea of this passage is that satellites are now used in _________.
| A．taking pictures of the atmosphere |
| B．receiving pictures of the atmosphere |
| C．doing other work in many ways |
