初中英语易混短语

1. as…as 和……一样

中间必须用形容词或副词原级。例如：

This classroom is as big as that one.这间教室和那间一样大。

He runs as fast as Tom. 他和汤姆跑的一样快。

否定结构：not as/so…as,“不如……”。上面的两个句子可分别改为：

This classroom is not as/so large as that one.这间教室不如那间大。He doesn’t run as/so fast as Tom.他跑得不如汤姆快。

2. as soon as 一……就……

用来引导时间状语从句。若主句是一般将来时，从句要用一般现在时。例如：I’ll tell him the plan as soon as I see him.我一看到他就告诉他这个计划。He’ll go home as soon as he finishes his work.他一完成工作就回家。

3. be busy/enjoy/hate/go on/finish doing sth. 忙于/喜欢/讨厌/继续/完成做某事

在enjoy, finish, hate, go on, be busy等词语后，一般用动词-ing形式作宾语。例如：

Lin Tao is busy making a model plane.林涛正忙着做飞机模型。

My mother enjoys taking a walk after supper.

我妈妈喜欢晚饭后散步。

I hate watching Channel Five.我讨厌看五频道。

When someone asked him to have a rest, he just went on working.当有人让他休息一会儿时，他仍继续工作。

I have finished writing the story.我已经写完了故事。

4. fill…with 用……装满......；be filled with 充满了……；be full of 充满了......

①be filled with 说明由外界事物造成的此种状态，表示被动。例如：The box is filled with food.

②be full of说明主语处于的状态。此外，还可表示程度，意为“非常”。例如：The patient’s room is full of flowers.

The young man is full of pride.那个年轻人非常骄傲。

③这两种结构还可以相互改写。例如：

I fill the box with food. The box is full of food.

5. be good/bad for 有利于/有害于……

此句型是：be+adj.+for+n.结构。例如：

Doing morning exercises is good for your health.

Always playing computer games is bad for your study.

6. be used to(doing) sth. 习惯于……

后必须接名词或动名词，可用于现在、过去、将来的多种时态。be 可用get,become来代替。例如：

He is used to life in the country.(He is used to living in the country.) He will get used to getting up early.他将会习惯于早起。

注意：be used to do 的意思是“被用来做……”。例如：

Wood is used to make paper.木材被用来造纸。

7. both…and…两者都……

用来连接两个并列成分;当连接两个并列主语时，其后谓语动词用复数。例如：

8. can’t help doing sth. 禁不住做某事

help在此的意思是“抑制,忍住”，其后接动词-ing形式。例如：

His joke is too funny. We can’t help laughing.

9. sth. costs sb. some money 某物花费某人多少钱

此句型的主语是物。cost一词带的是双宾语，它的过去式、过去分词和原型一样。This book cost me five yuan.

10. either…or…不是……就是……,或者……或者……

用来连接两个并列成分，当连接并列主语时，谓语动词与邻近的主语保持一致。You may either stay here or go home.

Either she or I am right. = Either I or she is right.

11. enough (for sb.) to do sth. 足够……做……

在此结构中,for用来引出不定式的逻辑主语。例如：

12. feel like doing sth. 想要做……

此处like为介词，后面跟动词-ing形式。此句型与would like to do sth.同义。例如：I feel like drinking a cup of milk.

13. feel/find/think it adj./n. to do sth. 认为某事……
