三、重点语言点
1. ---- I really hate to go shopping. 。 ---- So do I . 我也是。
So do I .为倒装句,表示前面提到的肯定情况也同样适合另外一个主体,表“某某也一样”,结构为“so + be /情态动词/ 助动词 + 主语”。 如:
Jim is a student, so is Tom. 吉姆是一名学生,汤姆也是。
Jim can swim, so can Tom. 吉姆会游泳,汤姆也会。
Jim likes sports, so does Tom. 吉姆喜欢运动,汤姆也喜欢。
如表前面不怎样,后面“也不”怎样时,其结构为“ neither/ nor + be /情态动词/ 助动词 + 主语”。如:
Jim wasn’t Chinese, neither/ nor were they. 吉姆不中国人,他们也不是。
Jim can’t speak Japanese, neither can I . 吉姆不会说日语,我也不会。
Jim didn’t go there, neither did I . 。
如前后两句表达的是同一个主体,则不能倒装,表“的确如此”。如:
Jim is a good student. So he is. 吉姆是一名好学生,的确如此。
Jim swims well. So he does. 吉姆游泳很好,的确如此。
2.At that time, China was the country with the largest population in the world.
那时,中国是世界上人口最多的国家。
population为不可数名词,表示人口的多少只能用 “large”或 “small”修饰,提问人口用“what”, The population of Shanghai is larger than that of Beijing. 上海的人口比北京多。
What’s the population of China?= How many people are there in China?
中国的人口有多少?
3. Great changes have taken place in China. 中国发生了巨大变化。
take place 指必然性的“发生”或有计划、安排之内的“举行”。如:
The meeting will take place next Friday. 会议将在下周五举行。
happen 指偶然的、没有预料的“发生“,其结果往往给人带来不幸或麻烦。如:
The accident happened yesterday. 事故发生在昨天。
※两者都不用于被动语态。
4. The population has increased a lot. 人口增长发很多。
increase 可作及物动词也可作不及物动词。其含义是“增长,增加,加强”等。
increase by… 指“增加了……”; increase to…指 “增加到……”
5. …, and about one fifth of the people in the world live in China.
而且世界上大约五分之一的人口生活在中国。
one fifth 是分数表达法。英文分数表达法:分子为基数词,分母为序数词,先读分子后读分母。当分子大于1时,分母的序数词则变为复数,直接在词尾加“s”。如:
one fourth 四分之一; three fourths 四分之三;
one second 二分之一; two thirds 三分之二
6.It has worked well in controlling China’s population.
它在控制人口数量方面取得了显著的功效。
work well in doing sth. 表“在……方面很有功效”, 如:

be short for… 表“是……的缩写”, 如:
TV is short for television. TV是television的缩写形式.
8. Can all Chinese families offer their children a good education?

offer to do sth. “(主动)提出做某事” 如:
She offered to cook for her mother. 她提出帮她妈妈煮饭。
9. I can’t go shopping in big stores unless I travel for a couple of hours.
我得花几个小时,才能到大的商场购物。
a) unless = if not 表“除非…; 如果不”,引导条件状语从句。如:
I won’t go unless I hear from you. = I won’t go if I don’t hear from you.
如果你不通知我,我就不去。
Unless Bill studies hard, he’ll fail in the exam. 如果比尔不努力, 他不会通过考试的.
b) a couple of… 表 “几个人或几件事”, 如:
a couple of years ago 几年前; a couple of students 几个学生
couple 指任何两件同类的东西; 如:
