sothat与suchthat用法区别-精.ppt

so...that和such...that用法区别
so...that和such...that的意思均为“如此……以致……”,都用来引导结果状语从句。但二者用法不尽相同,现归纳如下:
1) so...that结构中的so为副词,后面跟形容词或副词;
such...that中的such为形容词,后面接名词(名词前可以有形容词或副词修饰)。
例如:
He became/is so angry that he couldn‘t speak. 他变得很生气,以致说不出话来。
It was such a fine day that we went out for a walk.
2) 当that前的名词有表示数量多少的many, much, few, little等修饰时,只能用so,不能用such.
例如:
There was so much noise outside that we couldn't hear the teacher.
He had so many falls that he was black and blue all over.
注意:若名词前的little解释为“小(的)”意思时,则仍用such, 而不能用so.
例如:
It is such a little sheep that it can‘t run ,它不能够跑得快。
3) 当that前是单数可数名词且该名词前面有形容词修饰时,so与such可以互换,
即:so+adj.+a/an+n.
=such+a/an+adj.+n.。
例如:
She is so good a teacher that we all love her.
=She is such a good teacher that we all love ,我们都爱她。
4) 当that前是不可数名词或复数可数名词时,则必须用such,不能用so来代替。
例如:
It was such fine weather that they all went swimming.
They are such nice apples that we would like to eat them.
( ) was___difficult a question that___people could answer it. ,few  ,a few 
,few  ,a few
A
由此可知第一空应当使用so,故排除C和D;根据前一句子“问题如此难”可知“几乎没有人可以回答出来”,故正确答案为A项。a few表示肯定意义,意思为“一些”;few表示否定意义,意思是“很少,几乎没有”。
seem
seem可用作连系动词或不及物动词,意为“似乎,好像”,其常见的用法有:
,形容词,分词,名词和介词短语搭配。如:
+不定式(短语)
I seemed to hear a voice in the distance
我好像听到那边有声音。
Your advice seems to be doing me a favor .
你的建议似乎帮了我个大忙。
I seem to have caught a cold .
我好像感冒了。
seem to be doing sth
表示不定式的动作和主句中seem是同一个时态,
比如,He seems to be doing his homework.
他好像正在做作业;seem to do
表示不定式的动作发生在主句动词seem之后,
比如It seems to rain. 好像要下雨了。
rain的动作,是发生在seem之后的;seem to have done sth
表示不定式的动作发生在主句动词seem之前,
比如 she seems to have finished her homework. 她好像做完了她的家庭作业。finish的动作发生在seem之前
