表目的的英文状语从句短语
目的状语从句就是在复合句中表示主句动作发生目的的状语从句。引导目的状语从句的从属连词主要有so that(以便，为了), in order that (为了，以便) 。从句中一般含有can, could, may, might, will, would 等情态动词。此外,in case(以防，以免), lest(免得，以防), for fear that(以免，惟恐),on purpose that ,in the hope that也可以引导目的状语从句。
1. 用so that引导：so that此时的意思是“以便”。如：
She burned the letters so that her husband would never read them. 她把信都烧了，这样一来她丈夫就永远看不到了。
注意：so that引导目的状语从句与引导结果状语从句时的意思不一样。
引导目的状语从句的 so that 有时可省so 或 that，即单独用 so 或 that 来引导目的状语从句。如：
Check carefully, so any mistake will be caught. 仔细检查，以便任何错误都可检查出。
Bring it closer that I might see it better. 拿近些，使我能看得清楚些。
2. 用in order that引导：in order that的意思是“为了”。如： He studied hard in order that he could pass the exam. 他努力学习以便能考试及格。
3. 其它
Be careful lest you fall from that tree. 要当心, 以免从树上摔下来。
He hurried home for fear that he might miss his guests. 他急忙赶回家，唯恐见不到他的客人。
The teacher raised his voice on purpose that the students in the back could hear more clearly.
用in case引导：in case此时的意思是“以防”“以备”。如：
I always keep a bottle of wine by in case friends call round. 我平时总存着一瓶酒以备朋友来时喝。
It may rain—you’d better take an umbrella (just) in case it does. 可能会下雨你，最好带把伞，以防万一。
注意： in case既可引导目的状语从句，也可引导条件状语从句，主要视句意而定：
In case he comes, let me know. 如果他来，告诉我一声。 Tell me in case you get into difficulty. 遇到困难请告诉我。
【注】in case引导目的状语从句，从句有时可用“should+动词原形”这样的形式：
Take your coat in case it rains (should rain). 带着雨衣以防下雨。
目的状语从句与状语短语的转换
为了简洁起见，当目的状语从句的主语与主句的主语相同时，目的状语从句有时可用表目的的不定式短语替换：
He got up early so that he could catch the early bus. / He got up early so as to catch the early bus. 他起床很早以便赶上早班车。
He came in quietly in order that he shouldn't wake his wife. / He came in quietly in order not to wake his wife. 他轻轻进来，以免把他妻子吵醒。
