因为这位同学借的书已经过期了 不能再更新延期
no,you can't 不能延期了
you should have done that before the deadline 你本应该在到期之前延期的.
should have done 表示应该做却以前没有做
can't 表示一定不会 should have done 表示应该已经还了
b 回答must 要用don't need to 或者needn't
如果答案选b,应该是 you do not need to .
should have done 本应该 “你本应该在截止日期之前”
当 must 意为“准是”“一定是”,通常只用于肯定句。若用于否定句或疑问句,则用 can 代之。如:
That can’t be the only way. There must be other ways of solving the problem. 那不是解决问题的唯一办法,肯定有另外的办法。
Jane’s light is on. She must be at home...

当 must 意为“准是”“一定是”,通常只用于肯定句。若用于否定句或疑问句,则用 can 代之。如:
That can’t be the only way. There must be other ways of solving the problem. 那不是解决问题的唯一办法,肯定有另外的办法。
Jane’s light is on. She must be at home. She can’t be out. 简的房间里开着灯。她一定在家,不会出去的。
收起
这道题很容易被迷惑,后面的句子带有责备,所以用can't表示不可以。
