because既是并列连词也是从属连词,具体看所在句子的结构:1、because后面不加从句,就和and用法相同,是并列连词。2、because后面加状语从句,就和that用法相同,是从属连词。
because的语法
(1)because的基本意思是“因为”,强调直接造成某种结果的理由和原因,所引导的原因状语从句多置于主句之后,有时为了强调,也可置于主句之前,并用逗号与句子的其他部分隔开。
(2)because还可用来引导让步状语从句,这时,通常用于否定句或疑问句中。 (3)because有时还可引导表语从句。 because和because of的用法区别 一般句型结构为: 句子+because+句子 because+句子,+句子 because of+名词/代词
从以上句型结构可以看出,Because是连词,连接两个句子,如: I was worried because Mary was late.我很着急因为玛丽迟到了。 Because I was tired,I went home.因为我很累,我回家了。
Because of是复合介词,其后接名词、代词、动名词、what从句等。如: I was late because of the rain.我因为下雨迟到了。
Because of之后可接what从句,但不能接that从句或没有引导词的句子。如: He left the company because of what the boss said at the meeting.他离开了这家公司,因为老板在会上讲的话。
He didn’t come because of his illness.(NOT ……because of he was ill).他因病没有来。
