当句子是一般否定时,为避免歧义,在口头表达时,需在because前稍作停顿。在书面表达时,可在because前用逗号将从句和主句分开。
例如:
He didn't go to school, because he was ill. 他没去上学,因为他病了。
2.Alabama is the first US state to sue since the Deepwater Horizon rig, owned by Transocean and leased to BP, exploded in April and sent millions of gallons of oil into the sea.
这句话的主干是:Alabama is the first US state。to sue...是动词不定式做后置定语,修饰state。since引导时间状语从句。owned by and leased to是过去分词做后置定语,修饰Deepwater Horizon rig。
3.Sierra Leone's Human Rights Commission has called on South Africa to hand over uncut diamonds allegedly given to the supermodel Naomi Campbell by the former Liberian President Charles Taylor.
这句话的主干是前面半句。given to是过去分词做后置定语,修饰uncut diamonds。call on sb to do要求某人做某事。
