　　2. 我參加CET-6考試的理由。

　　[參考范文]

　　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 good both to my studies and to my personal advancement.
