　　Why I Take the College English Test Band 6　Some students think it unnecessary to take CET-6. They hold this views because CET-6 is　not compulsory and they can get a degree so long as they pass CET-4. However, I think it　necessary and beneficial to take CET-6. The reasons are obvious.

　　First, if I decide to take CET-6, natually, to pass CET-6 becomes a goal I set myself and　with a goal to strive towards I will continue to study English hard. Of course my English will not be neglected in the third and fourth years. Besides, if I pass CET-6, I can get a certificate which, to some extent, shows my experience and qualification so that I can compete with other in job-hunting. Most important of all, a good knowledge of English will help my work and scientific research in the future.

　　All in all, taking CET-6 does well both to my studies and to my personal advancement.

　　六級英語寫作專題練習范文：

　　In the developing countries great changes took place in life expectancy and infant mortality in the period from 1960 to 1990. In 1960 life expectancy was very low, while infant mortality ws very high. However, in 1990 life expectancy increased, whereas infant mortality declined.

　　There are many reasons for the changes, but in general, they come down to three major ones. First, their living conditions were improved. In the old days people in the developing countries suffered hunger and were exposed to the elements. Nowadays they are well fed and housed. Naturally they live longer than before. Besides, the medical condition was also improved and so the adequate medical treatment ensures the adults’ health and reduces infant mortality. Most important of all, in the early 60s there were constant wars in some developing countries because of the colonial rule and so a lot of people were killed in wars. Nowadays most developing countries have become independent countries and their people live a peaceful life.

　　In conclusion, the national independence and social stability are responsible for these changes.
