四、【辨析】because of/because
【考点精讲】
◆because of表示因果关系时，后不能接从句，但能接名词、代词或动名词。eg：
Helen didn\'t attend the party because of her mother\'s coming.由于她母亲来了，海伦没有参加晚会。
◆because意为“因为”，它引导的从句一般放在主句的后面，回答以why引起的特殊疑问句，只能用because。eg：
Tom didn\'t go to school because he was ill.汤姆没上学，因为他病了。
—Why didn\'t John go to the park？约翰为什么没去公园？
—Because he had to look after his younger sister.因为他得照看他的小妹妹。
【拓展】because有时可与because of互换使用。
Tom didn\'t go to school because he was ill.＝Tom didn\'t go to school because of his illness.汤姆没上学，因为他病了。
Mo Yan\'s books have been sold out in many book stores________his winning of the Nobel Literature Prize.(2013，宜宾)
A．because B．since
C．as D．because of
【解析】D。句意：由于诺贝尔文学奖的获得，莫言的书在很多书店销售一空。四个选项都可以引导原因状语，前三者是连词，后面接句子，只有because of后面接名词、代词或动名词短语，故选D。
