模块语法详解

状语从句（2）：原因、目的和结果状语从句

一、原因状语从句：

从句在复合句中做状语，表示行为的原因。通常由从属连词because, since, as, for引导。

1. because意为“因为；由于”，它引导的原因状语从句，表示直接的原因，语气最强，通常放在主句后，若需强调则放在主句之前；它常用来回答why提出的问题；because不能与so同时在一个句子中使用；because与because of有时可以互相转换。如：

My mother was angry because I didn’t do well in the exam. 妈妈生气是因为我考试没考好。

I am late because I miss the first bus.=I miss the first bus so I am late. 我迟到是因为我错过了第一班车。

2. since意为“因为；既然”，它引导的原因状语从句，一般位于主句之前，表示显然的或已为人知的理由，较为正式，语气较because弱。如：

Since everyone is here, let’s start. 既然大家都到齐了，我们就开始吧。

Since you don’t feel well, you’d better have a good rest. 既然你感觉不舒服，你最好休息一下。

3. as意为“因为；由于”，它引导的原因状语从句，表示附带说明的“双方已知的原因”，语气比since弱，较为正式，as引导的从句一般放在句子的开头。如：

As all the seats were full, he stood up. 由于所有的座位都满了，他只好站着。

As the weather was bad, we didn’t go for a picnic. 由于天气糟糕，我们没有去野餐。

4. for意为“因为”，它引导的原因状语从句，表示所说的理由是一种补充说明，只是个人主观解释，大多数情况下并不构成真正原因，它引导的状语从句只能放在主句之后并且必须用逗号将其与主句隔开。如：

He must be in now, for the light in his room is on. 他现在一定在家，因为他房间的灯是亮着的。

She was clearly upset, for her eyes were filled with tears. 她显然很难过，因为她眼里饱含泪水。

二、目的状语从句：

从句在复合句中做状语，表示行为的目的。从句部分是用以补充说明主句中谓语动词发生的目的。它通常由so that（以便，为了），in order that（为了）引导，从句通常位于主句后。另外从句中通常含有情态动词：may, might, can, could, should, would, be able to等情态动词。如：

We used the computer so that /in order that we might save time. 我们使用计算机是为了节省时间。

I get up early every day so that /in order that I can get to school on time. 我每天早起是为了能按时到学校。

【拓展1】so that 引导目的状语从句时，可与表目的的动词不定式(not) to do.../so as(not) to do.../in order (not) to do...或in order that互换。注意：主、从句主语不一致时不能转换。如：

We went to the airport so that we might meet Professor Yang there. 我们去了飞机场以便我们在那儿能遇到杨教授。

=We went to the airport to meet Professor Yang there. 我们去了飞机场以便我们在那儿能遇到杨教授。

=We went to the airport in order to meet Professor Yang there. 我们去了飞机场以便我们在那儿能遇到杨教授。

=We went to the airport so as to meet Professor Yang there. 我们去了飞机场以便我们在那儿能遇到杨教授。

【拓展2】so that可引导结果状语从句，表结果，意为“因此；所以”，主从句间用逗号隔开，常用于一般过去时，表示过去的情形，从句里没有表目的的情态动词。如：

He worked hard at his lessons, so that he gained high grades in the exams. 他努力学习，结果考试获得了好成绩。

He spoke at the top of his voice, so that the students at the back heard him. 他说话声音很高，结果后面的同学都听见了。

三、结果状语从句：

从句在复合句中做状语，表示行为的结果，引导结果状语从句的连词由so，so....that，such...that引导。本模块主要学习so引导结果状语从句。so意为“因此；所以”，引导结果状语从句时，表示由于某个原因才做某事，从句前可用逗号与主句隔开。如：

He wanted to help patients, so he became a doctor. 他想帮助病人，所以他当了医生。

She trained hard, so she became a great player later. 她训练刻苦，因此成了著名的运动员。
