1、使用否定的时候，比如：什么什么对个人不好，对社会也不好。为什么不来个倒装？Never/neither/nor/seldom/rarely/on no account + is…

2、当你想表达“如果怎么怎么样，就是另外一种情况”—虚拟语气。为什么不来个虚拟倒装？Were(Had) it…，something would......

3、强调句的使用：It is people who…/ it is something that…

4、让步句式的使用：“无论什么样的情况下”However[No matter how] whatever[no matter what]等等…，

还有一种Cogent as this response is, it has some minor errors.

Somewhat reasonable as the issue presents, it does not experience a case-by- case examination.

还有比较常用的although...

It should be admittedly that…，however it does not follow that/

5、疑问句。用于开头，来个设问句，在自问自答，提出自己观点；用于段中，比如举设想的例子：Can you imagine that…?/ How can one imagine…?

6、定语从句(这个大家一般用的比较熟练，但是注意不要太罗嗦…society where(in which)…，/ something on which we depend (on which…based)

7、The more…the more…句式的使用。人们越幸福，社会越稳定啦、等等。

8、Not only…but also的使用。很好用的，ETS经典的6分范文：专才VS通才不就用了两个嘛？

9、without的使用。从反面说，很是能够增加字数。还是那篇范文的结尾，就来了两个非常妙的without。

10、还有一些比较常用的：There is no denying that…/ there is no doubt that…/

11、还有imong的一个句子：So powerful the scandal is that Watergate became the talk of the world.如此..以至于..

       句式这一方面我还很欠缺啊，要是各种变幻的句式能运用自如(向往ing)，再加上深邃的思维分析，就不愁ETS不给高分了。
