Do you understand the words may, might, possible, possibly & probably?
might 是 may 的过去式,但表示可能性时没有很大区别,只是表示一般将来的可能性时,might 比 may 的可能性要小。因为 might 和 may 都是情态动词,所以,他们后面应加动词原形,即:
S (主语) + might/may + do sth.
possible, possibly, probably 的常用结构:
It is possible that ....
It is possible to do sth.
S (主语) + will probably / possibly + do sth.
probably表示的可能性比possibly要大。
