    语法要点

    状语从句简介

    1. 除了用单词或短语来形容动词、形容词或副词之外,还可以用从句来形容上述词类,这类从句称为副词从句,也称状语从句。

    2. 在四句例句中,when we were in New York, because he was sleepy分别是主语的状语从句部分,同时when, because是状语从句的引导词。

    3. 关于标点:当状语从句位于主句之前时,就比如像第一句和第三句,通常用逗号来分开主句和状语从句。当状语从句跟在主句之后时,就比如像第二句和第四句,不用逗号来分离主句和状语从句。


    重要备注

    状语从句是从属子句,它们不能够单独出现。如果要运用状语从句,应该和独立分句一块儿使用。

    语法要点:

    1. 该类词汇主要用于连接时间状语从句与主句。时间状语从句说明主句动作发生或进行的时间。状语从句由该类词汇引导,其位置通??梢苑旁诰涫谆蛘呔淠?。

    2. 该类词语用于连接理由或原因状语从句与主句。原因状语从句说明主句动作发生或者进行的原因,其中,because语气较强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或者已为人们所知,就用as或者since.

    3. 该组词语主要连接让步副词从句与主句。让步状语从句一般翻译为“尽管…”或者“即使…”,就是我们日常生活中用的“退一步说…”

    4. 该组词汇用于连接条件状语从句与主句。在英文中,条件是指某一事件实现之后(状语从句中的动作),其他事情(主句中的动作)才能发生,通常译作“假如”。衍生出来的条件状语从句的意思有,“万一…”.
