The change in the chart may be attributed to a number of factors, but the following are the most critical ones. First, developing countries’ economy has been developing at a considerably high speed in the past decades. Therefore, people have more extra money to improve their health. Secondly, the advances in medical sciences and boom of medical industry provide citizens with more opportunities to cure their diseases. Last but not least, people have attached greater importance to their quality of life, thus they have spent more money and time to build up their bodies.
In a word, this chart is a perfect indicator of developing nations’ fast expanding economy and people’s 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.
(或If this trend continues, developing countries will soon approach the developed countries in terms of health care. People will live longer and healthier lives. The result of this will be happier and more productive populations.)
18. Film Is Giving Way to TV
(a)
The latest statistics show that the number of people attending cinemas is getting steadily smaller. At the same time, the number of television viewers is growing at almost the same rate.
Experts say that these two trends are connected in three ways. First, over the past few decades television sets have appeared in almost every home. Second, films very quickly become available on video, and can be shown on the TV screen. Third, it is becoming more expensive to make films, and so the prices of cinema seats are rising.
