Actually, it has become so widespread that it has severely affected people’s daily life and hindered the development of the global economy. A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. What’s worse, pollution and waste of fresh water aggravate the situation. In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water.

【范文】 From the chart we can see clearly that the number of Internet surfers in our country has increased from 26.5 million in July to 45.8 million in July , and then to 59.1 million in January . In my mind, the reasons why the Internet surfers are on the rise are as follows. First, the Internet can help us accomplish many tasks, including both work and play—searching for information has become more convenient than ever, and safe online business is no longer a dream. Besides, surfing the Internet is becoming cheaper and cheaper—more and more people can afford it. The negative effects of the Internet are also clear. To begin with, sitting too long before the computers is harmful to our body, especially our eyes. Second, more and more people become indulged in playing video games or chatting online, which are time-consuming. All in all, I should say the advantages outweigh the disadvantages. The key lies in whether we can make good use of it to enhance both work and study. 【点评】 首段论述从至国内上网顾客总人数旳变化趋势。

Many men work on construction sites, while many women work as dishwashers in restaurants or babysitters for city dwellers. Three reasons, in my mind, can account for this social phenomenon. First and foremost, the limited land can no longer produce enough crops for an ever-increasing rural population. In the second place, there are far more opportunities in big cities—rural laborers dream of earning money through hard work. Last but by no means least, many of them want to live permanently in big cities, because they admire the way of living there, and wish their children to receive good education. I firmly believe that if we try our best to create a healthy social atmosphere, rural laborers will make greater contribution to our nation. 【点评】 本题谈论旳是一种社会现象。
