1、such和so都可以用来表示程度,意思是“如此;这样”,但用法却不相同。 1.such是形容词,用来修饰名词,名词前有无形容词都可以;so是副词,用来修饰形容词或副词,形容词后可以省略名词。例如:He is such a(big)fool.他是个(大)傻瓜。 He is so foolish(a man).他是如此愚蠢(的一个人)。 2.单数名词前有不定冠词与形容词时,so和such的位置不同。前者为“so+形容词+冠词+名词”,后者为“such +冠词+形容词+名词”。例如: I know such a clever boy.我认识如此聪明的一个男孩
2、。 I know so clever a boy.我认识如此聪明的一个男孩。 3.so后即使有形容词,也不能修饰复数名词或不数名词,而such则可以。例如: They are such useful books.它们是如此有用的书。 He gave us such good food.他给了我们这么好的食物。 4.名词前有表示“多、少”意义的many,much,few,little等修饰词时,要用so,不用such。例如: There are so many flowers in our school garden.我们学校的花园里有那么多的花。 Yo
3、u'll find English a bridge to so much knowledge.你会发现英语是通向如此丰富知识的桥梁。 I have so little money that I can't lend you any.我的钱很少,不能借给你。 5.当little表示“小”的意思修饰可数名词时,其前只能用such,不能用so。例如: I have never seen such little sheep before.我以前从没见过这么小的绵羊。such..that和so..that的区别和用法such…that…与so…that…都可以
4、用来引导结果状语从句,意为“如此……以致……”。(1)such是形容词,它所修饰的名词可以是可数名词,也可以是不可数名词;名词前面可以带形容词,也可以不带。如果其后是单数可数名词,前面需加不定冠词a或an。因此,such…that…的句型结构可分为以下三种:①such+a(n)(+adj.)+单数可数名词+that从句。如:She is such a good teacher that all of us love and respect her.她是一位很好的老师,我们都敬爱她。Table tennis is such an interesting
