　　Now more water is needed.The problem is how we can avoid a serious water shortage in the future.  3 Scientists are making study in this field.Today，In most large cities water is used only once and then runs to the sea or rivers.but it can be used again.Even if every large city reused its water，the water will still not be enough. 4 .

　　The sea seems to give us the best answer.There is a lot of water in the sea.All that needs to be get the salt out of the sea water.This will be expensive，but it has already been used in many parts of the world.   6 So you see，if we can find out a way，we’ll be in no danger of drying up.

We spent a day in the country and picked a lot of flowers. Our car was full of flowers inside! On the way home we had to stop at traffic lights, and there my wife saw the bookshelf.  It stood outside a furniture（家具）shop. “Buy it,” she said at once. “We’ll carry it home on the roof-rack（车顶架）. I’ve always wanted one like that.” What could I do? Ten minutes later I was twenty dollars poorer, and the bookshelf was tied on to the roof rack. It was tall and narrow, quite heavy too.  As it was getting darker, I drove slowly. Other drivers seemed more polite than usual that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea. After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake（超车）?” Just at that time a police car did overtake. The two officers（警官）inside looked at us seriously when they went past. But then, with a kind smile they asked us to follow their car through the busy traffic. The police car stopped at our village church（教堂）. One of the officers came to me. “Right, sir,” he said. “Do you need any more help now?” I didn’t quite understand. “Thanks, officer,” I said. “You’ve been very kind. I live just down the road.” He was looking at our things: first at the flowers, then at the bookshelf. “Well, well,” he said and laughed. “It’s a bookshelf you’ve got there! We thought it was--er, something else.” My wife began to laugh. Suddenly I understood why the police drove here. I smiled at the officer. “Yes, it’s a bookshelf, but thanks again.” I drove home as fast as I could.

Jess really felt very happy. When he arrived at his seat in the classroom that morning, he found an invitation（请柬）on his desk. It was from some of his classmates asking him to join their camping trip. This was the first time he was asked to join in an out-of-school activity. Why were they asking him now? Nobody seemed（似乎）to like him. In fact, he had been so lonely (孤独) that he ate a lot to make himself feel less lonely. As a result, he had put on a lot of weight, and this gave the children something more to make fun of him.

Cindy, who was standing near Jess when he read the invitation, went out quickly to tell the others that the trick had worked. Everyone was happy that Jess thought that was true. But there was no camping trip. The whole thing was made up.

At first, Cindy thought it was fun. But later, when Jess told her that he was going to buy a sleeping bag with his pocket money, Cindy had a second idea. She knew that Jess’s family had little money, and she hated to see him spend his pocket money on something he would never use. Cindy also hated to tell Jess the truth (真相). Her close friends would be unhappy with her.

What could she do now?

1.What would happen if Cindy told Jess the truth?

2.If Jess really bought a sleeping bag, _________.

3.From the story we know _________.

4.Which is the best title for this passage?
