问题描述:
can could 有什么区别 i can`t find out which way that i should go
i can`t find out which way that i should go
can 跟 should 要不要对应 前面要不要用could
答
不需要,都可以.can和could的区别如下
could 有两种意思,一是做为 can 的过去式,比如我们讲故事时,因为大多用过去式,所以其中所有的can 都要用成could.另外,在虚拟语气中,也是要用过去时表与现在相反.I wish I could fly.
第二种,就是表意愿,比can 更委宛.
Could I buy this book?带有点祈求的味道.---至于怎么用,就看你的情境及你说话对象和你自己的强势程度来决定了.从语法上说,均可以用.
