I’m leaving because I’m full.(2)for语气较because要弱得多，只能置于主句之后，对前面主句的内容加以解释或推断如：It’s morning now, for the birds are singing.(很显然，鸟叫不可能是“现在已是早上”的原因。)(3)since，as“既然，由于”，它们通常被置于语句之前，但有时却相反。Seeing all of the children already seated, he said,“Since everyone is here, let’s start.”①在回答why的问句时; ②在用于强调句型时; ③被not所否定时。(5) 一些介词短语同样可以表示原因，这样的短语有：because of, thanks to, due to, owing to, as a result of等。--- He couldn't walk because his leg was broken// because of his broken leg---They stayed in because the weather was bad//because of the bad weather更多详情咨询添加老师微信（18780205961）获取！
