词组比较

anyone用于否定句与疑问句，但还可以用在肯定句作为主语。someone用于肯定句例句：I don't know anyone in the classroom.There is someone there.Anybody can answer the question.

want

wang to + 动词原形I want to see him.

want + 名词The little boy wants more toys.

want + 人 + to + 动词原形He wants me to mail the letter for him.

no/not

no 是形容词，表示“没有一个”。not 是副词，表示“不”的意思。no == not any。I have not any money. == I have no money.He does not have any money. == He doesn't have any money. == He has no money.

both/all

两者之间one...the other...

三者之间one...another...the other...

介词与物体的关系

inside + 物体  表示在该物体之内

behind + 物体  表示在该物体的后面

under + 物体  表示在该物体的下方

next to + 物体  紧邻于该物体

及物动词、不及物动词

简单的判断方法：A __ B.B被A __.如果动词在空白处都通顺，则是及物动词，反之是不及物动词

数量的形容词

之后可以接复数名词者：few 有少数，没几个a few 有几个several 数个（比a few多）many 许多个

He has few friends. 他没几个朋友——他的朋友很少。I have a few friends. 我有几个朋友。She has many friends. 她有许多朋友。a. few表示“没几个”，有否定意味；a few 表示“有几个”，有肯定意味。b. quite a few 不少的，相当多的 = manyc. only a few 只有几个 = few

之后接不可数名词者：little 很少，没多少a little 有一点much 许多

He has little money. 他没多少钱——他几乎没钱。He has a little money. 他有一点钱。He doesn't have much money. 他的钱不多。a. little 表示“没多少”，有否定意味；a little表示“有一点”，有肯定意味。b. quite a little 不少的，相当多的；c. much用于否定句，而不用肯定句中。肯定句应使用a lot of 或lots ofd. a great deal of 亦表示“许多的，大量的”，之后须接不可数名词

可接复数或不可数名词：some 一些a lot of(=lots of) 许多的plenty of 不少的

助动词

之后接动词原型。must 表示道德与义务（如爱国、孝顺父母），表示现在或者未来的状况，不能用于过去时have to 表示不得不去做，可以表示过去时，用had to

should = ought toWhat should Dan do? => What ought Dan to do?

might 表示较低的可能形，may可能形较高

take

take + 人或物 + to + 地方Please take me to the station.

He can take the work home.由于home是副词，相当于表示场所的副词there，here等，置于句尾修饰动词时，这些副词之前不能置介词to。Let's go to home now.(x)Let's go home now.(Y)但home之前若置所有格代词（my、his），则home变成名词，可以加to。Let's go to my home.

why

Why + 动词原型 => Why should I/we + 动词原型例句：Why stay here?  => Why should I stay here?Why be quiet?   => Why should I be quiet?

Why not + 动词原型？ => Why can't you/we + 动词原型?Why not be quiet?      => Why can't you be quiet?Why not stay here?     => Why can't you stay here?

名词

作主语To work with him is pleasant.It is pleasant to work with him.

作宾语I decided to visit him tomorrow.He is planning to study abroad.He promised me to write the letter.

置于be动词之后，作表语，此时主语亦多位表示“愿望、决心”等名词My only wish before I leave is to see her one more time.His plan is to marry her soon.

此时动词不定式置于被修饰的名词之后，修饰该名词I have some work to do.That's not the right way to learn English.

副词

名词短语

疑问副词修饰之后的动词不定式

when

名词从句

种类

that引导的名词性从句

whether引导的名词性从句

be动词Is he happy？ => whether he is happy

助动词（can，will，have）Will he come? => Whether he will come

do/does/did 先冠以whether，次将do、does或did去除，疑问句中的动词原形再按do、does、did及主语还原成应有的时态Do they like it？ => Whether they like it

疑问词（what、where、when、how、why、who、whom、which、whose等）

be动词Who is he? => Who he is

助动词When will he come? => When he will come

含有do、does、did的疑问句How did he do it? => how he did it

注意：若疑问代词who、what、which作主语，该疑问句变成名词性从句时，句子结构不变Who will come? => Who will comeWhat happened? => What happenedWhich has been bought? => Which has been bought

定词从句该从句视为形容词、修饰之前的名词

who、whom专门修饰人，换言之who、whom之前一定有一个表示人的名词。who在从句中作主语，whom则作宾语

which用以代替除人以外的一切事物（动物、植物、静物、地方、概念等）的关系代词，在所引导的定语从句中，可作主语、宾语。前面一定要有可被代替（除人以外）的名词。

whosewhose之后应置名词，即“whose+名词”，在所引导的定语从句中可做主语或宾语

thatthat 可等于who、whom或which，但that之前不可置逗号
