仁爱版英语九年级上册Unit1 Topic2 SectionB 重难点讲解
SectionB 重难点讲解【1】And it is increasing by 80 million every year. 并且它（世界人口）正在以每年8000万的速度增长。
（教材P11）increase为动词，意为“增加，增大(数目）”，构成短语increase by, increase to (1) increase by后加倍数或百分数，意为“增加了……倍/百分之…”。
如：The population has increased by 2% in this country. 这个国家的人口已经增加了2%。
(2) increase to后接具体的数字，意为“增加到了……”。
如：His salary increased to 10, 000 yuan a month.他的月薪增加到了1万元。

作“人口数”讲时，相当于the number of 故针对人口数量提问时用What’s the population of ...? 而不能用how many。
通常用big/large，small来修饰人口数的多少。
具体的人口数用“has a population of +数字”来表示。
如：China has a population of about 1.3 billion.中国大约有13亿人口。
【3】Luckily, China has already carried out the one-child policy to control the population. 幸运的是，中国已经实施了独生子女政策来控制人口增长。
（教材P11）carry out 实行，实施，执行。
