【知识点1】 population 是不可数名词，意为“(某一地区的)人口，全体居民”。其用法如下：
⑴population是集体名词，没有复数形式，当它作主语，表示整体概念时，其后的谓语动词用单数。如表示个体概念，它前面有百分数或分数时，谓语动词要用复数形式。
The population of the world is growing too fast. 世界人口增长过快。
About 80 percent of the population of China are peasants.
中国约百分之八十的人口是农民。
⑵询问某国、某地有多少人口时，需用特殊疑问词“What”或“How large”。而不用how many 或how much。
其句型为：“What+be+the population of+地点？”或“How large/big+be+the population of+地点？”这两个句型中的be动词须用单数。
What’s the population of America
=How large is the population of America 美国的人口是多少？
【活学活用】
_______ is the population of your country
A. How many B. How much C. Which D. What
A
【知识点2】 million是数词，意为“百万”。它的用法如下：当表示“确切的数量（确数）”时用“具体的基数词＋million”结构，million用单数形式，后面不能接介词of；当表示大概的数量（概数）时，million用复数，后跟of, 构成“millions of”结构，意为“数以百万计的；成百万上千万的”。
There are two million people living in this city.
这座城市居住着两百万人。
Millions of people visit the Great Wall every year.
每年，数百万人参观长城。
【拓展】与million有相同用法的数词还有：hundred(百)，thousand(千)，billion(十亿)。
【活学活用】
There are _____ books in the National Library.
A. twenty millions B. twenty million of C. twenty million
C
【知识点3】prepare 准备，预备，其常用短语：prepare sth. 准备某物；prepare for sth. 为某事做准备；
相当于get ready for sth.; prepare to do sth.准备做某事; 相当于get ready to do sth.
【活学活用】
---- What are you preparing _____ your party
---- I’m thinking about who I’ll invite.
A. at B. for C. with
B
【知识点4】too much，too many和much too的区别：
①too much+不可数名词，意为“太多的”。

她花太多钱买衣服。 ②too many+可数名词，意为“太多的”。
They bought too many eggs yesterday.
昨天他们买了太多鸡蛋。 ③much too+形容词/副词， 意为“太……”。

你走的太快了，慢点。
【活学活用】

D
【知识点5】 noise, sound 与 voice的区别：
①在一般情况下，凡能听到的声音都可称作sound，且其作为“声音”主要指一种抽象概念，一般用作不可数名词。②noise 主要指大声的、令人不愉快的声音，尤其指噪音，可用作可数或不可数名词。
③voice 主要指人讲话或唱歌的声音，通常用作可数名词。
用noise, voice或sound 填空。

【知识点6】 one fifth 五分之一，英语中分数的表示法为：
分子用基数词，分母用序数词，当分子大于一时，分母使用复数形式。“分数+of+名词”短语做主语时，谓语动词的单复数取决于of后面的名词的数。如：七分之一 one seventh；七分之二 two sevenths。
