In London, there has always been a main problem. In order to solve this problem, the government has decided to have a bike revolution(革命). It has decided to provide 6,000 bikes for the people to rent. The government encourages local people to ride bikes in order to solve the traffic problem.
More than 12,000 people have agreed to the idea. Some of them ask for more than one key. Although there are not enough bikes, an official(官员) from the government said that they would find some ways to deal with such a shortage.
Local people can get these bikes at special docking stations（停靠站）.There are about 315 docking stations across the city. About 12,450 keys have already been handed out to the local people, but only 6,000 keys can be used now.
Let’s see the cost you need to pay. One key costs ￡3, and the cost of using the bike is ￡1 for an hour. The cost per hour increases as the hours increase, so it will cost ￡50 if you rent the bike for 24 hours.

A

The one-child policy in our country has made most families much smaller than before. That is to say, there are fewer children in a family. But the population of China is still growing faster. Why? In fact, it’s a serious problem not only in China, but also in the whole world. It’s reported that the world population is expected to reach 9,200,000,000 by 2050. There are two important reasons. First, there are still more and more babies born every year. Next, people in the world can live much longer than before.

The earth is too tired, but it has to burden(担负) more in the future. Who can save her?

　　Look at your watch for just one minute. During that time in 1981, 239 babies were born in the world. Perhaps you think that isn’t much. In the next hour, over 14,000 more babies will be born on the earth. Just think how many more babies there will be born in one year. If this goes hour after hour, what will happen in a hundred years?

　　The population problem may be the greatest one of the world today. Two thousand years ago, there were only 250 million people on the earth. Four hundred years ago, the number was over 500 million. The population may be 8,000 million by the year 2000.

　　In China, the population problem is quite great, too. The Party’s leaders are paying much attention to it, but lots of people don’t think so. They like to do what they want. Some love more children. Some wish to have both son and daughter. Other would like to have not only daughters but also sons. Haven’t they ever thought the population problem? If nothing is done to stop this, things will get worse and worse. The figure of the world’s population will certainly be a terrible one. There will be only standing room on the earth some day.

And now there are about 6.465 billion in the world. There are more than 1.3 billion in China. Last year the USA gave its latest report on the problem of the world's growing population. The world's birth rate is higher than the death rate.

　　As the population continues to grow, we are facing more and more problems. Though we have good harvest year after year, millions of people are still in hunger. Lots of buses have been put into use, yet they still remain too crowded. Each year thousands of new buildings are built, but they still can't meet the needs of the people. Much money has been raised to set up one school after another, however, they seem too crowded to hold so many children. Maybe each person will have one half to one square meter of space to live in in the future. There will be hardly enough space for anyone else.
