目的、结果状语从句.ppt

目的、结果状语从句,讲解,一、目的状语从句,简介 目的状语从句：从句部分是用以补充说明主句中 谓语动词发生的目的的状语从句。 目的状语从句的谓语常含有may, might, can, could, should, will, would等情态动词。 引导目的状语从句常用的连词有： so that（以便）， in order that（为了；以便） E.g. You must speak louder so that you can be heard by all. (该句为目的状语从句的普遍形式）,【注意】in order that与in order to的区别： in order that+从句 in order to+动词原形 （ in order to后面加的那个不叫目的状语从句，叫目的状语） in order to“为了”,后接动词原形，做目的状语。 E.g.I get up early in order to catch the early bus. in order that 为了，后接从句，做目的状语。 E.g. I get up early in order that I can catch the early bus.,二、结果状语从句,简介 结果状语从句常由so that或suchthat引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。 so和 such 结果状语从句其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。,such + （a/an）+形容词+名词 =so+形容词+（a/an）+名词 注意so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 是名词性的，只能用such搭配。 因此，sothat与 suchthat之间的转换既为 so与such之间的转换。 E.g. The boy is so young that he cant go to school. He is such a young boy that he cant go to school.,总结,结果状语从句的从句部分是补充说明主句中谓语动词发生的结果的，通常位于主句之后。结果状语从句中通常不用情态助动词，但must can could除外。such用在（形容词）名词之前；而so要用在形容词或副词之前，so或that有时会省略掉。,练习,根据句意，用so或such填空。 1.
