六级写作快速提高精讲（25）

　　It can be seen from the table that popular fiction is most popular with American students, accounting for 65.9% of book circulation in the library. General nonfiction comes next, taking up 18.2%, while books concerning science, technology and education take up only 10.8%. The least preferred category is that of art, literature and poetry, with a circulation rate of merely 5.1%.

　　A number of factors could account for the reading preferences, but the following are the most critical ones. Firstly, popular fiction is fascinating to the young students. Secondly, books about science and technology are usually too complex and difficult to read. They often contain many special terms which most students cant understand. Finally, in todays market economy, much more emphasis is laid on practical and vocational books rather than arts or poetry.

　　When it comes to me, poetry and art are my favorites. Such kind of books can nourish my mind, broaden my horizons and render me a fresh feeling. Reading a piece of good poetry tends to relieve my burden and lessen my tension, making me more creative and dynamic. It gets me into an imaginary world, fresh and beautiful. I just love it!

　　15. Changes in the Ownership of Houses in China

　　It can be seen from the chart that there have been dramatic changes in the ownership of houses in China in the past 50 years. While the percentage of state-owned houses has dropped from 70% in 1950s to 20% in 1990s, that of private houses has soared from 30% to 80% during the same period of time.

　　A number of factors could account for the change in the chart, but the following are the most critical ones. First, thanks to the policy of reform and opening-up, the nations economy has been developing at a considerably high speed in the past decades. Therefore, people have more extra money to improve their housing. Secondly, other relevant state policies and the boom of real estate industry provide citizens with more opportunities to choose their own dwelling places. Last but not least, people have attached greater importance to their quality of life. Thus, more of them have purchased houses in their own favor.

　　In a word, this chart is a perfect indicator of Chinas fast expanding economy and peoples rising standard of life. Although a series of problems have arisen in the process, it is reasonable for us to believe that they can be solved in the near future with effective measures taken by both the government and the public.
