19.3 原因狀語從句 | ||
比較:because, since, as和for 1) because語勢最強,用來説明人所不知的原因,回答why提出的問題。當原因是顯而易見的或已為人們所知,就用as或 since。 I didn't go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2) 由because引導的從句如果放在句末,且前面有逗 號,則可以用for來代替。但如果不是説明直接原因,而是多種情況加以推斷,就只能用for。 He is absent today, because / for he is ill. He must be ill, for he is absent today. |
