since的知识点讲解

since(prep)……以来 (adv)从那以后,其后 (conj)……以来;既然,因为

讲解:since是重点考点之一.请同学们重点学习

1)since表自从,是完成时的标志,可作为介词使用,其后+具体时间,还可作为连词,其后+句子

:We've been waiting here since two o'clock.从2点钟开始,我们就一直等在这里。

: I haven't seen her since she left London自从她离开了伦敦,我就没见过她。

2)since不与瞬间动词连用(完成时的易考点)

常考的转换: come to某地--- be in待在某地; leave---be away离开某地;die---be dead死; join---be in+组织, 参加了某组织; marry---be married结婚. Buy/borrow---have 买/借来

2) 表示既然,只做连词用,其后只能+句子,比because的语气弱.

词组: ever since 从那时起一直
