so 和such 的用法？

So与such是英语中两个常用词.这两个词的用法很多,且易混淆,初学英语者往往搞不清楚,因而使用是经常出错.文本就它的一些用法作一粗浅讨论.讨论主要以分析实例进行.
首先,我们应该弄清so是副词,修饰形容词和副词,在句中充当状语.Such为形容词修饰名词,在句中作定语,请看下面几个句子.
① The fish is so long.
② Don't drive so fast, it's dangerous.
③ Fred is so good a man.
④ It was such interesting meeting.
⑤ There were such a lot of people.
以上句子中,①,②句比较简单,so为副词,分别修饰形容词long和副词fast.③句中的so修饰good,可用形容词such改为:
Fred is such a good man.
这句话和原句的意义不变,但用so要用so+adj+a/an+n.的结构来表达.用such需用such+a/an+adj+n.的结构来表达.④句中仍可按③的形式表达,但也可写成:
The meeting was so interesting.
其句意不变.⑤句中的such也可换为so,但更据习惯搭配,应将a lot of 变为many为宜,如其后所修析的名词为不可数名词,还需将a lot of改为much.如:
With such a lot of time,they should have finished their homework
用so则为:
With so much time, they so have finished their homework.
因此遇到这种情况,我们可将such+a lot of+n.结构变为so+many/much+n.结构
再看这样一个句子:
The enemy scattered in such a hurry.
可改为:The enemy scattered so hurriedly.又如:
The plane flies at such
