目的状语从句的用法：用so as to do sth表目的【第一篇】

so as to do sth是to do sth的变体，意思是“以便”“为了”“为的是”等。用so as to do sth表示目的时，它通常用于句末。如：

I left a message so as to be sure of contacting her. 我留下了张条子以便与她取得联系

The two lovers dropped back so as to be alone. 那对情人落在后面，为的是两人好单独在一起。

I always keep fruit in the fridge so as to keep insects off it. 我总是把水果放在冰箱里，以防虫子叮咬。

表示目的的so as to do sth有时也可放在句首(但是若so as to do sth是表示结果，则不可放在句首)。如：

So as to show his boss what a careful worker he was， he took extra trouble over the figures. 为了向老板显示他是个工作非常细心的人，他在这些数字上费了比平常更多的力气。

so as to do sth的否定式是so as not to do sth，意思是“为了不……”“以免”。如：

They tiptoed upstairs so as not to wake the baby. 他们踮着脚上楼，以免吵醒孩子。

We left in the daytime so as not to arouse suspicion. 我们在白天离开以免引起怀疑。

I shut the door quietly， so as not to wake the baby. 为了不惊醒宝宝，我轻轻地关上门。

目的状语从句的用法：用in order that表目的【第二篇】

in order to和in order that均可表示目的，两者的区别是，前者引出不定式，后者用以引导目的'状语从句。与用in order to do sth表示目的的情形相似，in order that引导的目的状语从句可以位于主句之前或之后。如：

We arrived early in order that we could get good seats. 我们到得早，以便找到好座位。

These men risk their lives in order that we may live more safely. 这些人甘冒生命危险，为的是让我们生活更安全。

I bought a new car in order that my wife might learn to drive. 我买了一辆新车，以便我妻子学习驾驶。

In order that you may create such a picture， you have to possess certain artistic weapons. 创作这样的画，你得具有某些艺术手段。

目的状语从句的用法：用in case表目的【第三篇】

in case用于引导目的状语从句时，意思是“以防”“以免”。如：

He took his umbrella in case it should rain. 他带上了雨伞，以防下雨。

You’d better take the keys in case I’m out. 你最好带上钥匙，以防我不在家。

Listen out for the baby in case she wakes up. 注意听宝宝的动静，她醒来好知道。

in case 引导的目的状语从句有时也可位于主句之前。如：

In case anyone was following me， I made an elaborate detour. 为了防止有人跟踪我，我特地绕了弯路。

注：也有人认为这样用的in case 从句为原因状语从句，意思是“因为怕……”。比较：

I had a snack， just in case there was no time to eat later. 我吃了些点心，以防过会儿没有时间吃饭。(将in case译成“以防”，将之视为目的状语从句)

I had a snack， just in case there was no time to eat later. 我吃了些点心，因为怕过会儿没有时间吃饭。(将in case译成“因为怕”，将之视为原因状语从句)

Here's a contact number， in case there should be a problem. 这是联系电话，以防有问题出现。(将in case译成“以防”，将之视为目的状语从句)

Here's a contact number， in case there should be a problem. 这是联系电话，因为怕有问题出现。(将in case译成“因为怕”，将之视为原因状语从句)

目的状语从句的用法：用for fear (that) 表目的【第四篇】

for fear that 用于引导目的状语从句时，与 in case 大致同义，意思是“以防”“以免”。如：

He’s working hard for fear (that) he should fail. 他在努力工作唯恐他会失败。

She finally ran away for fear that he would kill her. 她最后逃走了，因为怕被他杀了。

Scientists reject a total ban for fear it will undermine efforts to stop the spread of malaria. 科学家们反对全面禁止，以免削弱为防止疟疾扩散所作的努力。

注：与in case一样，for fear that 引导的从句有时也被理解为原因状语从句，并将其翻译为“因为怕……”。比较：

Shut the window for fear that it may rain. 把窗子关上以防下雨。(将for fear that 译成“以防”，将之视为目的状语从句)

Shut the window for fear that it may rain. 把窗子关上，因为怕下雨。(将for fear that 译成“因为怕”，将之视为原因状语从句)
