英語情態動詞真的是太容易讓人糊塗了！
同意的，請舉手！
今天，我們就來一起分析一下，如何使用英語情態動詞，表示“可能”和“不可能”
Possible（可能，但不確定）
1.將來的possible
could, might 和 may
They might come later. (= Perhaps/Maybe they will come later.)They may come by car. (= Perhaps/Maybe they will come by car.)If we don't hurry we could be late. (= Perhaps/Maybe we will be late)2.現在或過去的possible
could have, might have 和 may have
3.普遍意義上的possible（一般都是可能如此）
現在用can；過去用could
It can be very cold in winter. (= It is sometimes very cold in winter)You can easily lose your way in the dark. (= People often lose their way in the dark)It could be very cold in winter. (= Sometimes it was very cold in winter.)You could lose your way in the dark. (= People often lost their way in the dark)不可能Impossible:
現在或將來不可能用can't ；過去不可能用couldn't
That can't be true.We knew it could not be true.Probable（可能，且確定性很大）
1.肯定發生，且理由充分
must
