课堂导学
1、 the population of china is about 1.37 billion.中国的人口大约有1.37亿。
The population of 表示“…的人口”,谓语动词用单数,修饰population一般用small和large。
Eg: the population of Indian is the largest in the world.
英语常用的数字单位与中文有所不同,为:hundred, thousand, million,billion,这些数词与具体数字连用时不变复数,如:1.37 billion, ten hundred, 但是用来表达成百,成千,数百万等时要用复数,后面加of, 如 millions of, hundreds of .
2、population increase is a big problem in many countries.人口增长在很多国家是一个大问题。
(1)Increase , 名词,意为“增大,增长”,如:
Because of the fast increase of population and human desire, the human living environment, health and safety are becoming worse and worse.由于人口需要的快速增长,人类的居住环境、健康和安全正变得越来越糟糕。
(2)Problem,名词,意为“麻烦;问题”,have problems/trouble/difficulty doing sth.“做某事有困难”,如:
Some parents have problems talking with their children.有些父母和他们的孩子交流有困难。
3、that’s almost one fifth of the world’s population, that is, about 7 billion.那几乎是世界人口也就是约70亿的五分之一。
(1)One fifth 表示五分之一。
分数由基数词和序数词一起来表示,基数词作分子,序数词做分母,除了分子是“1”以外,其他情况下序数词都要用复数形式。
Three fourths 四分之三
Two thirds 三分之二
(2)that is 在句中作插入语,有时也用that is to say,“那就是说;也就是说”
