1) 如果原因构成句子的最主要部分，一般用because。因此， because引导的从句往往放在句末。例如： I stayed at home because it rained. ---Why aren’t you going? ---Because I don’t want to. 2) 如果原因已被人们所知，或不如句子的其它部分重要，就用 as或since。since比as稍微正式一点。as和since 引导的从句 一般放在句子的开头。例如： As he wasn’t ready, we left without him. Since I have no money, I can’t buy any food. 3) for用来补充说明一种理由，因此，for引导的从句几乎可以 放在括号里。for引导的句子不放在句子的开头。例如： I decided to stop and have lunch，for I was feeling quite hungry.

C. is from

if和whether都可作“是否”讲，在引导宾语从句是一 般可互换。例如： I wonder whether (if) you still study in that school. 在下列情况下，只能用whether,不能用if： ①.在不定式前。例如： I haven’t made up my mind whether to go there or not. ②.用or并列两项以上时。例如：I don’t now whether he comes or not. ③.从句作介词宾语时只用whether不用if。 It depends on whether it will be fine.那得看是不 是晴天。 ④.作discuss等动词的宾语时，用whether不用if。
