such与so的区别与用法
such与so的意思都是“如此,这样”。但两者用法根本不同。
1、such后面主要是修饰名词。即:such+a/an+adj.+n.。如果名词是不可数名词或复数名词,则不可以用不定冠词a或an。如: ①He has such a beautiful kite. ②The garden has such fresh air.
2、so后面只能跟形容词或副词。即:so+adj.或adv.如: ①The tiger is so big. And the cat is so small.
3、它们后面还可以与that连用,that引导的是结果状语从句。即:such…that和so…that意思是“如此……以致于……”。要注意so后的中心词是形容词,such后的中心词是名词,如:
①His brother is so young that he can't go to school.
②She is such a clever girl that she can make much progress in math exam.
注:当名词前有many,much修饰时,不用such,用so,如: ①There were so many people that we could hardly move on. ②I ate so much food that I didn't want to go anywhere.
e.g.①He spoke so fast that we could not understand him. ②They are such delicious cakes that I want to eat another two. ③It is such an interesting story that I want to read it again.
either...or...与 neither...nor... 一、either...or...
either...or...意为"或者……或者……;不是……就是……"之意。表示两者之一,连接句子中两个并列的成分。例如:
When the girl is happy, she either sings or dances. 那个女孩高兴时,不是唱就是跳。(此句中either...or...连接两个动词,因为主语是单数第三人称,谓语动词要用其相应的形式。)
either...or...连接两个主语时,其谓语动词应与最近的一个主语在人称和数上保持一致,这就是我们通常说的"就近原则"。例如:
Either you or I am going there tomorrow. 明天要么你去那里,要么我去那里。
注意:如果把上句变成一般疑问句,助动词形式与主语you保持一致,所以要用are提问,而不是am。例如:
Are either you or I going there tomorrow? 明天是你还是我去那里?
Either you or he has lunch at school. 其一般疑问句应为:Do either you or he have lunch at school? 是你还是他在学校吃午饭?
若要对either...or...句型进行否定时,只需把either...or...换成neither...nor...即可。例如:
Either you or she is good at drawing. 变为否定句应为:Neither you nor she is good at drawing. 你和她都不擅长绘画。
我们还可以单独使用either,其意为"两者中的任何一个"。例如:
There are many shops on either side of the street. 街道两边有许多商店。这个句子也可以这样表达:There are many shops on both sides of the street. 在街道两边有许多商店。
either用在否定句的句末,表示"也"的意思。例如:
If you don\'t go there. I won\'t, either. 如果你不去那里,我也不去。
二、neither...nor...
neither...nor...表示"既不……也不……"。其含义是否定的,可连接任意两个并列的成份。例如:
She likes neither butter nor cheese. 她既不喜欢黄油也不喜欢乳酪。此句中neither...nor...连接两个宾语。当neither...nor...连接两个主语时,也应遵循"就近原则"。例如:
Neither dad nor mum is at home today. 今天父母都不在家。
若将neither...nor...句型变为肯定句,只需把neither...nor...改为both...and...即可,同时谓语动词必须用复数形式。例如:
Both dad and mum are at home today. 今天父母都在家。
还可以单独使用neither作主语,表示"两者中没有一个"。例如:
Neither of them likes football. 他们俩都不喜欢足球。
neither或nor还有另外一种用法,就是当表达一个人没有做某事,另一个人也没做同一类事时,可用neither或nor进行简略回答,其结构为:Neither / Nor+助动词 / 情态动词 / be动词+主语。例如:
He doesn\'t go to school by bike. Neither / Nor do I. 他不是骑自行车上学,我也不是。
They didn\'t go to the park yesterday. Neither / Nor did we. 昨天他们没去公园,我们也没去
