2018年仁爱版九年级英语上册第四单元知识点归纳

U4T1SA

1 be allowed to do sth.被允许做某事,

allow sb. to do sth.允许某人做某事；

allow doing sth.允许做某事。

e.g. She allowed me to go fishing.

她允许我去钓鱼。

We don’t allow smoking in the reading room.

我们不允许在阅览室吸烟。

2 too much既是形容词短语，也是副词短语，所以它既可修饰名词也可修饰动词。

e.g. too much water； eat too much

太多的水吃得太多.

另外注意too much后接的是不可数名词；

too many +可数名词复数；

much too常用在形容词或副词之前修饰形容词或副词。e.g.much too long 太长，much too fast 太快

3 show v. 给……看。show sth. to sb. = show sb. sth.

把某物给某人看。

e.g. Can you show your new watch to me? =

Can you show me your new watch?

你能把新手表给我看看吗？

show sb. around... 带领某人参观。

e.g.Welcome to my city. I’ll show you around some places of interest. 欢迎来我市，我将带你参观一些名胜古迹。

show n. 展览、展示,on show 展出。

e.g.There is a TV play on show on CCTV-1.

在中央一台有一部电视剧在播放。

4 be made of/from 由……制成。

be made of (看得出原材料)；

be made from (看不出原材料)。

e.g. The desk is made of wood.

be made by sb. 由某人制造。

e.g. The model plane was made by my father.

5 be used for 被用来做……。

e.g. Pens are used for writing.

钢笔被用来写字。这种结构也可以变成be used to do sth.。类似的结构还有:be used as被用作；be used by被谁所用。

e.g. English is used as a foreign language in China.

英语在中国被当做外语。

Computers are used by some people as toys.

电脑被有些人当玩具用。

be used后还可以跟不定式。

e.g. This machine can be used to study English.

6 wish(希望)后面接that从句常用虚拟语气。本句表达康康的主观臆想，不一定能实现，像这种表示主观愿望和假想的语气叫虚拟语气。当表示现在的愿望，从句中谓语动词用过去式；当表示将来的愿望，从句中动词用could/would加动词原形。

e.g. I wish that I didn’t have to go to work today.

我希望今天不用上班。

I wish I could have my own house.

我希望我能拥有自己的房子。

7 come true 变成真的，实现。come这里起到连系动词的作用。go也有类似用法。

e.g. The fish has gone bad.

这鱼已经变坏了。

it是形式主语，真正主语是that引导的从句。

3 no one和none都表示否定，但用法有所不同，它们的区别是：

a. no one用来指人，含有not even one（连一个人也没有）之意，其后不能接of短语。用作主语时，谓语动词要用单数。e.g. No one knew who took the book by mistake.

没有人知道谁误拿了这本书。

No one likes a person with bad manners.

谁也不喜欢不讲礼貌的人。

b. none不仅指人也可指物，其后常接of短语，构成“none of+名词/代词”结构。当名词是复数时，谓语动词单复数均可。e.g. None of the houses has/have a large garden in some big cities.

在一些大城里，没有一幢房子带有大花园。注意：
