1. There are too many rules!

too many ＋可数名词复数 , “ 太多”

e.g. I have too many books to read.

too much ＋不可数名词 , “ 太多”

e.g. There’s too much milk in the glass.

Language Points

2. I have to go to bed before ten o’clock.

1) go to bed  “ 上床睡觉” , 此时等于 be in bed,

in 和 bed 之间不能用冠词 , bed 也不用复数 ,

be in bed 还有“卧床”的意思 。

e.g. He is in bed for 10 years.  他卧床 10 年了。 Dave has to be in bed early every night.

大卫每晚必须很早睡觉。

3. After dinner, I can’t relax either.

副词 either 在此处表示“也”，用于否定句句末，

用法与表示肯定或者陈述的副词 too 相似，可用

逗号与语句的主题隔开。

e.g.

You like English. I like it, too.

My father can’t speak English. My mother

Can’t (speak it), either.

4. There are a lot of things you can do.

此处的 a lot of things you can do 是一个名词

短语，句子 you can do 起修饰、限定名词 things

的作用。英语中当句子限定修饰名词时要放在

该名词之后。

e.g.

There are a lot of songs you can sing.

A: Do you have a library at school?B: Yes, we do. And we have ______ for school library.A: What are they?B: We have to keep quiet in the _______. We have put our umbrella ________ the library. We can’t ______, ____ ____ ______ ______ or listen to the music in it.
