英语原因状语从句详解+题目训练 1、 【定义】:指在句中用来说明主句原因的从句。 2、 【重要性】:中高考必考、写作中可用的高级句型。 3、 【连接词】 because(因为), as(由于), since(既然), now(that)(既然), seeing (that) (由于,鉴于), considering (that)(考虑到), for(因为), given (that) (考虑到)等。 4、 【用法】 1. because, since,as和for的区别: (1) because引导的原因状语从句一般放于主句的后面,because从句位于句首时要用逗号分开,放在句末时,可不用逗号分开。 because表示直接原因, 语气最强, 回答why引导的疑问句。 注意:because 和so 不可同时出现在一个句子里。 例如: I do it because I like it. = I like it so I do it. (2) since引导的原因状语从句一般放于主句之前表示已知的、 显然的理由(通常被翻译成“既然”= now that ), 较为正式, 语气比because弱。 例如:Since you are free today, you had better help me with my maths. (3) as 引导原因状语从句时表示附带说明的“双方已知的原因”,含有对比说明的意味,语气比since弱, 较为正式, 位置较为灵活(常放于主句之前)。 例如:As it is raining, you’d better take a taxi. (4) for引导的是并列句表示原因但并不说明主句行为发生的直接原因, 只提供一些辅助性的补充说明, for引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。 例如:He could not have seen me, for I was not there. 2. because从句与 because of短语的转换 例如:He can’t come because he is ill. =He can’t come because of his illness. 他因病不能来。 题目训练 0.
