12、从句)和定语从句,Eg: I think(that) he likes football.(2)如果主句的动词是 think, believe;如果主句的主语是第一人称,变为否定句时,要否定主句,译成中文时,则否定从句。 (否定前移) Eg: I believe you will leave here. Eg: I dont believe you will leave here.2、 when,while ,before, after , as soon as ,till, until , sincewhen, while, till, until, since, after, before
13、, as soon as 等是连接时间状语从句的连词。当主句是将来时,从句要用一般现在时。(1)注意 while 所引导的从句的谓语动词只能是延续性的,不能用点动词。 (如 begin,stop)Eg: While I read, she sang.
