so 和such 用法区别.ppt

so 和 such 用法区别 so与such都有“如此、这么、那么”的意思，可进行同义改写，但用法不同。 Ⅰ. so是副词，修饰形容词和副词； 而such是形容词，修饰名词。 1. 后接单数可数名词时，词序不同。 so的词序为： so+ adj. + a（an） + n. such的词序为: such +a（an） +adj. + n. 它们可以表达同样的意思，可以进行同义改写。 so nice a coat =such a nice coat? such an interesting book =so interesting a book 2. 后接复数名词或不可数名词时，只能用 such，而不能用so. 　such beautiful flowers 　such clever children such sweet water 3. 复数名词或不可数名词前有many，few，much，little修饰时，只能用so而不能用such，这是一种固定用法。 　　so many books 　　so few people 　　so much money 　　so little milk Ⅱ. 和“that”连用时，意思基本一样，但句型结构不同。 “so…that…”句型结构为： so + adj. （adv.） +that… so + adj. +a（an）+单数n. +that… so +many（few）+复数n. +that… so +much（little）+不可数n. +that… This book is so interesting that I have read it three times. 　　He spoke so fast that we couldn‘t understand him. 　　It was so hot a day that nobody wanted to do anything. 　　There were so many people that we could hardly move on. “such…that…”句型结构为： 　such + a （an）+adj. +单数n. +that… 　such + adj. +复数n. +that… 　such +adj. +不可数n. +that… 　　 She is such a pretty girl that everyone likes her. They are such delicious cakes that I want to eat another two. It is such sweet milk that we all want to drink it. 注意：由于so 和such后跟单数可数名词时，可以换用，同样“so…that…”与“such…that…”也可同义句改写。 This is so interesting a book that I have read it three times. 可改写成：This is such an interesting book that I have read it three times. 　3. so与that可以直接构成词组“so that”，引导目的和结果状语从句，表示“以便、以致”的意思。如： 　　He worked hard so that he could pass the exams. 为了能通过考试，他学习很认真。 （但such没有这种用法） some exercises （一）用so…that…和such…that…填空： 1.
