not have to = needn t 意思“不必” 四、语法要点

1. How much 与How many 的意思是“多少” 。

两者都表示询问事物的数量，区别是,How much 是询问不可数名词的数量,而How many 则是询问可数名词的数量。

你需要多少土豆?

注意 ：当不可数名词前有量词表示数量时,则用how many 询问多少。 How many kilos of meat do you need? 你需要多少公斤的肉?

How many tins of dog food can we buy with that?

你能用那买多少狗食？ 2. “no” 和 “none” 的用法

我们使用“no” 和 “none” 来说明什么东西都没有。“no” 是一个形容词必须跟名词连用。 “none”是一个代词，不能跟名词连用。 e. g.

A: Hello, Daniel. Is there any bread on the table?

B: No, there is no bread, mum.

A: What about chips? How many are there? B: There are none.

A: Are there any eggs? B: No, there are no eggs, either.

A: I guess there is nothing on the table now. B: Yes, you are right. 3. 定冠词“the”的用法小结：

当表示独一无二的事物，或以前已经谈到的事或者表示说话者和听说者都已经知道这个人或事时，我们用定冠词
