such與so的區(qū)別與用法
such與so的意思都是“如此,這樣”.但兩者用法根本不同,與what和how引導(dǎo)的感嘆句相類似.
1、such后面主要是修飾名詞.即：such＋a/an＋adj.＋n.或a/an＋such＋adj.＋n..如果名詞是不可數(shù)名詞或復(fù)數(shù)名詞,則不可以用不定冠詞a或an.如：
①He has such a beautiful bike.We all go to see it.
②It's a such fine day.We al want to go to fly a kite.
2、so后面只能跟形容詞或副詞.即：和so＋adj.或adv.不過(guò),so后面也可以跟名詞,但該名詞必須是單數(shù)可數(shù)名詞.用法為：so+形容詞+a或an+單數(shù)可數(shù)名詞.如：
①The tiger is so big.And the cat is so small.
②She is so lovely a girl.
3、它們后面還可以與that從句連用.即：such…that和so…that意思是“如此……以致……”.如：
①She is such a clever girl that she can make much progress in math exam.
②His brother is so young that he can't go to school.
注：當(dāng)名詞前的形容詞為表示數(shù)目的詞時(shí),such必須換成so.如：
①There are so many people that we can't go past.
②I ate so much food that I didn't want to go any farther.
注意這一句話：He is such a little boy that he can't read or write.(這一句話中的a little不是“一點(diǎn)”的意思,而是“一個(gè)小的”的意思,所以,前面仍然用such,而不用so.
