英语连词学习中的五大注意要点
because语气强,表示客观必定原因：
He is absent, because he is ill.
因为生病，所以
他没来。
比较:He is absent,
for he is busy. （“生病”是
“缺席”的必定原因，“忙”不是必定原因。）
for
语气轻,表示非客观必定的原因,是主观可改变结
果的原因,甚至是猜想可能的原因:
He must be ill, for he is absent.
“缺席”不一
定是“生病”，只是交流猜想。
for
不能放句首,它是并列连词.
since,as
都是不讲自明的原因,是已知的原因.

a boy, let me carry the case.

you don‘t feel well,you had better stay at home.

时,多用when,是时间段时则三个连词都可以.

neither....nor, not only.....but
