拓展提升
1. I’m preparing some notes for a report called “Our growing population”.
prepare … for … 表示“为…准备…”。
e.g. He is preparing a dinner for his friends.
他正在为他的朋友准备晚饭。
2. That causes a lot of problems, such as too much traffic and noise.
too many 后面加可数名词，表示 “太多的”。
too much 后面加不可数名词，表示“太多的”。
3. I can’t believe it!
表示“简直难以置信”。表示一种惊讶。
4. The population of China is about 1.37 billion.
billion(十亿), million (百万), thousand (千)都是数字单位。当前面有数词时，这些数字单位不加s，当前面没有数词时，这些数词后面加s和of。
5. That’s almost one fifth of the world’s population, ...
one fifth 表示“五分之一”，fifth是序数词。
分数的表达：分子用基数词，分母用序数词。分子大于1时，分母 + s。
e.g. 2/5—— two fifths
6. Hang on a minute!
通常用来表示让某人等一下。
e.g. Hang on! I’ll be back in a minute.
7.population n. 人口
1) population 是一个集体名词，作主语时，若指一个地区或国家的整体人口，谓语动词通常用单数；若强调整体人口中的成员，谓语动词通常用复数。例如：
The population of the city is about 20,000.
这个城市大约有两万人口。
Three fifths of the population here are old people.
这里五分之三的人是老年人。
2) 表示一个地区或一个国家有多少人口时，可用 the population of ... is ... 或 ... has a population of ...。例如：The population of our country is 28,100,000.
我们国家的人口是二千八百一十万。
The city has a population of 50,000.
这座城市有五万人口。
形容“人口数量的多或少”可用large 或 small 修饰。
例如：
The population of Beijing is large.
北京人口众多。
3) 在询问人口时，要注意 population 和 people 的区别。前者通常用what来提问，后者用how many 来提问。例如：
What’s the population of Canada
加拿大的人口是多少？
How many people are there in the hall
大厅里有多少人？
朗读时，将每三位数看做一个单位，依次为billion，million，thousand。每个单位按照百、十、个位向下读，其中百位到十位之间要加入 and。
e.g. 729 ：seven hundred and twenty nine.
6,500,431,729：six billion five hundred
million four hundred and thirty one
thousand seven hundred and twenty nine.
