二、 参考范文
Nowadays, more and more people, especially in big cities, become interested in buying lottery tickets. According to chart 1, averagely 70 percent of those polled in the survey, held in three big cities, claimed to have dreamed of winning the big prize of five-million yuan. 85 percent of those polled in Guangzhou had had such a dream, compared with 65 percent and 60 percent, respectively, in Beijing and Shanghai.
The attraction of buying lottery tickets is obvious. The winner can get the biggest profit for the future with only a small investment. It realizes the beautiful dream of every participant-to be richer and to improve living standards. As is shown in Chart 2, should they win a big lottery, 81.3% of people would buy a new house, 61.9% would buy a car, and 61.7% would save the money for the education of themselves or their kids. And a great proportion of people say they would put the money in the bank or use it for investment or touring. Despite all the attractions brought by the lottery buying, it has also come under criticism. Some regard it as a kind of gambling, which is a potentially addictive behaviour.
In my opinion, buying lottery tickets is not so bad as some people think. Instead, it is good for society by creating new jobs and representing an important source of income for charity and sports causes. Of course, it is not a means of making money for individuals we should encourage, because the result is hardly predictable. Therefore, we should take a positive but cautious attitude towards lottery buying behavior.

Reading Books in Printed Form. or on Computer
The popularization of computer has made it possible to read books on computer. With it, there is much discussion about whether e-books will replace traditional print-on-paper books.
Some people say they like only e-books, which are quicker and more convenient to get and use. To get a needed book, one has to spend much time or money in searching for or buying it in bookstores, but one can just type in the title, author or other related information of the book to find it in minutes on internet. Sometimes one can even read the full content of a digitized book free of charge or instantly discuss about a book in an online forum. Moreover, a lot of information of books can be stored in a small compact disc, which is easy to take.
Other people, however, think printed books are still necessary. In the first place, too much time in front of the computer can cause eyestrain or increase radiation risks. Second, a printed book can be read at your convenience. One can read in bed before sleep or during a boring journey, without fussing with a computer.
In sum, since e-books and printed books have their respective advantages and can complement each other, I would like to combine the two ways to meet different needs. For quick reference, a digitized book will probably be useful. To appreciate a poem or a novel, I prefer the traditional way of reading on printed books.
