英語(yǔ)連詞的注意要點(diǎn)
連詞解釋
一.because,for,since,as,的區(qū)別
because語(yǔ)氣強(qiáng),表示客觀必然原因：

比較:He is absent, for he is busy. (“生病”是“缺席”的必然原因，“忙”不是必然原因。)
for 語(yǔ)氣輕,表示非客觀必然的原因,是主觀可改變結(jié)果的原因,甚至是猜測(cè)可能的原因:
He must be ill, for he is absent. “缺席”不一定是“生病”，只是交流猜測(cè)。
for 不能放句首,它是并列連詞.
since,as 都是不講自明的原因,是已知的原因.
Since I am a boy, let me carry the case.
As you don't feel well,you had better stay at home.
