副词修饰动词时候的位置
一个版本说多数副词都可以放在动词的后面,如果动词带有宾语,副词可以放在宾语后面。
比如
i know exactly what he's trying to do.
or
i know what he's trying to do exactly.
另外情态动词+动词原形时候也有2种表示方法
no one could exactly tell what was going to happen.
or
no one could tell exactly what was going to happen.
从另一语法书则看到副词在修饰动词时，当动词是to be,情态动词，助动词时，放在这类词的后面，其它情况(比如修饰实义动词）放在动词前面。
这类词主要包括不确定的时间如often alway 以及不确定的状态quite almost certainly
这种说法貌似和第一种说法有些冲突
那么第一句
i know exactly what he's trying to do.
是否改成
i exactly know what he's trying to do?

Answer 1

be动词之前行为动词之后,频率副词放动词前面，时间地点，自己看情况~~一般句首或句末
还有评注副词肯定放句首（obviously，sadly====），，经常用的就这些吧
