考点4 倒装句和n 的意思是"刚……就",它们所引导的从句中的谓语动词通常为过去完成时。hardly/barely/scarcely和n sner置于句首时,从句要倒装。警察刚把她带回来,她就从窗户再次逃跑了。N sner had the plice brught her back than she escaped again thrugh the windw.

表示"在(或到)……的地方"
意为"在(或到)……的各个地方"
3) 原因状从
①—Why are yu late? —Because I missed the early bus.—你为什么迟到? —因为我没赶上早班车。②Since/Nw that everyne is here, let's begin.既然大家都来了(大家都知道的事实,显而易见的原因),让我们开始吧。注:表因为的短语,t和f介词后加名词不能连接句子。 3 t: thanks t, wning t, due t3 f: because f, as a result f, n accunt f
