Because rain. for绝对不能单独使用。 5.语法类别 because:从属连词,引导原因状语从句； for:并列连词,连接两个并列分句,和 and/but/so同类 三、对比例句 1.She didn’t eat lunch because she had no money. （because:没钱是不吃饭的直接原因） 2.She has no money, for she didn’t go to work. （for:从 “没上班” 推测她没钱,是事后补充推测） 四、一句话记忆口诀 because 直因可句首,回答why是好手；for只在句末走,逗号隔开表猜由。 一、用 for 连接句子 1.We should use cloth bags.
