上周我们学习了情态动词can, may, must, need,同学们还记得它们有哪些含义和用法么?
为了加强记忆以及熟练运用,同学们要时常翻看之前的推文进行复习和巩固哦!
今天我们将学习另外四个常见的情态动词,快快往下看吧!
willwill 既可以作为情态动词也可以作为助动词。
用作情态动词时,will 最常见的用法就是表意愿,例如:I will devote all my life ti the cause of education.
同时 will 也可以表请求,例如:Will you come this way, please?
will 的过去式是 would,因此 would 具有与 will 相似的用法。
不过当 would 用来表请求时,往往比 will 的语气更委婉一些,例如:Would you open the door for me, please?
SHALL与 will 一样,shall 既可以作为情态动词,也可以作为助动词。
用作情态动词时,首先 shall 可以表命令或指示,译为“必须,一定”,例如:You shall do it, whether you want to or not.
同时 shall 也可以表义务,译为“应该”,例如:I shall let him cool down before discussing the subject.
此外,shall 也可以像 can 和 may 一样,表示请求,例如:Shall I send you the book?
shall 的过去式是 should,因此 should 具有与 shall 相似的用法。
另外 should 还可以表推测,译为“可能”,并表达的语气很强,例如:Here is something that should keep you awake at night.
OUGHT TOought to 也是具有情态动词特征的,一般被译为“应该”,可用于表推测、建议,例如:
That ought to be enough food for the four of us.(表推测)
You ought to have come to the meeting. It was interesting.(表建议)
HAVE TOhave to 是具有情态动词特征的,其含义和用法与 must 相似,例如:
Did she have to pay a fine?(必须,不得不)
This war has to end soon.(一定,表推测)
You have to try this recipe.(表建议)
