The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.
The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on 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(净化)factory. There it can be filtered(过滤) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

The Eiffel Tower was built in 1889, in memory of the 100th birthday of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 suggestions that were handed in, Gustave Eiffel’s was chosen.
However, at first, it was not well accepted by all and a group of people — including many well-known writers and painters at that time — were fiercely against its design.
Being about 300 meters in height, and 7,000 tons in weight, it was the world’s tallest building until 1930. It was a great project for France. 300 workers took two years to build it. It isn’t an ordinary building, since it is almost made of steel. For example, its body moves around at most 12 cm in heavy wind. Moreover, its height changes up to 15 cm according to the temperature.
It was almost destroyed in 1909, but was saved because of its antenna(天线), which is used for communication at that time. Beginning in 1910 it became part of the International Time Service. French radio and French television have also made good use of its height.
The Eiffel Tower has also seen a few strange things. In 1923, a journalist rode a bicycle down from the first level of it. And in 1954, a mountain climber climbed on top of it and tried to measure its exact height.
Anyway, although its birth was difficult, it is now well accepted all over the world. It has been considered as one of the symbols of Paris.

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

42.Land becomes desert after all trees are cut down because ________ .
A. roots of trees break up the soil
B. there are too many rainfalls
C. strong winds bring a lot of sand
D. there are no longer trees to keep the rain and protect the top-soil.

The young boy saw me, or rather, he saw the car and quickly ran up to me, eager to sell his bunches (串) of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known the bitterness of life. "Banana 300 naira. Peanuts 200 naira"
He said in a low voice. I bargained him down to 200 total for the fruit and nuts. When he agreed, I handed him a 500 naira bill He didn't have change, so I told him not to worry.
He .said thanks and smiled a row of perfect teeth.
When, two weeks later, I saw the boy again, I was more aware of my position in a society where it's not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents had raised me to be aware of the advantage we had been afforded and the responsibility it brought to us.
I pulled over and rolled down my window. He had a bunch of bananas and a bag of peanuts ready. I waved them away. “What's up”. I asked him. “I...I don't have money to buy books for school.” I reached into my pocket and handed him two fresh 500 naira bills.
"Will this help?” I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year. "Thank you, sir," he said. 'Thank you very much.”
When driving home, I wondered if my little friend actually used the money for school-books. What if he's a cheat (骗子)? And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? Later, I realized that I didn't know his name or the least bit about him, nor did I think to ask.
Over the next six months, I was busy working in a news agency in northern Nigeria. Sometime after I returned, I went out for a drive When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face
" Long time."
"Are you in school now?” I asked.
He nodded.
"That's good," I said. A silence fell as we looked at each other, and then I realized what he wanted. "Here," I held out a 500 naira bill. "Take this.” He shook his head and stepped back as if hurt. "What's wrong?” I asked. "It's a gift"
He shook his head again and brought his hand from behind his back. His face shine with sweat (汗水)。 He dropped a bunch of bananas and a bag of peanuts in the front seat before he said, "I've been waiting to give these to you."
