第一、活用介宾短语
在写作或口语中，往往需要举例子支撑自己的观点，在写例子时要活用介宾短语。
如果想说 地铁/大桥/我买的别墅还在建造中 ，别再说成 XXX is still being made ，
我们要这么说：
XXX is still under construction.
如果想说谁曾经跟某某学习过并且获得了成就，大可不说 A is B s teacher ，可以说
Under the instruction of XXX,
如果需要表达 某人帮助了我，所以我... 这样的意思的话，不必写 sb helped me so I ... ，要写
With the help of XXX, I
第二、巧用形式主语结构表达观点
写作或者口语当中一定要清晰表达自己的主旨观点，不要在一下笔就写 XXX is important XXX is good ，太老土。
如果要表达XXX 很重要，我们可以这样写：
It is of great importance to do XXX
importance也可以使用significance替代，变为
It is of great significance to do XXX
万一你想表达 我觉得XXX 特别不重要 ，就把great变成little或者no即可
It is of little importance to do XXX
It is of no significance to do XXX
如果想表达XXX 很有好处，可以这样调整：
It is beneficial to do XXX
可将beneficial变为advantageous
It is advantageous to do sth
第三、使用因果转折关系句型
在口语及写作当中，常常要说道 因为所以虽然但是 这样的语句，不要老是使用because, although。
当想表述 因为XXX，所以某人或某物变得更好了或者获益了
可使用thanks to XXX
当想表达 虽然XXX，但是XXX 可以说
Despite XXX Or In spite of XXX
如果虽然后面的内容很长，是一个句子，那就使用句型
In spite of the fact that, XXX
