1、because连词,“因为”,用来连接原因状语从句。
例如:I did it because he told me to.我做这事是因为他叫我做的。
Just because I don’t complain,people think I’m satisfied.因为我没发牢骚,人们就以为我心满意足了。
2、because of介词短语,“因为(某人/某事物);由于”,在句中作状语。
例如:They are here because of us.他们是为了我们而来到这里的。
He walked slowly because of his bad leg.他走得慢是因为腿有毛病。
3、because of和because的意思都是“因为”,区别在前者跟短语,后者跟从句。
例如:他们因为下雨没去博物馆。可用because和because of两种方法表示。
They didn’t go to the museum because of the rain.
They didn’t go to the museum because it rained.
