suchso的区别与用法

suchso的意思都是如此,这样。但两者用法根本不同。

1such后面主要是修饰名词。即:sucha/anadj.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aan。如: He has such a beautiful kite. The garden has such fresh air.

2so后面只能跟形容词或副词。即:soadj.adv.如: The 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:suchthatsothat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:

His brother is so young that he can't go to school.

She is such a clever girl that she can make much progress in math exam.

注:当名词前有manymuch修饰时,不用such,用so,如: There were so many people that we could hardly move on. I ate so much food that I didn't want to go anywhere.

e.g.He spoke so fast that we could not understand him. They are such delicious cakes that I want to eat another two. It is such an interesting story that I want to read it again.

either...or... 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""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。

neithernor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neithernor进行简略回答,其结构为:Neither / Nor+助动词 / 情态动词 / be+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
