学生在写作文的时候，有时候提笔不知道如何写什么，或者不知道应该怎样用英语准确的表达自己的意思。如果有这样的**况，我建议大家可以多准备一些例句，注意最重要的是你要知道如何才能利用好这些例句。 　　They will not ,he believes, get the health benefits(such as losing weight) without putting sufficient time into their exercise.这个句子是有关身体健康的句子，我们可以换几个词，就会变成别的。 　　win a place as 占有一席之地 　　The long-term trends lend support to the optimistic view 　　give sb an edge over sb 给予.....竞争的优势 　　The things that they catch or miss often determine whether a game will become a top seller or a failure. 　　The ugly advertisement is a blot on the beautiful landscape. 　　Various controversy have arisen in the university over this question. 　　Whether or not a part-time job is useful for a student's future depends on the type of job chosen. 　　这些是比较经典的句型，记住要会灵活运用，才可以举一反三，下笔的时候就会很轻松了。
