Section A

1. —I really hate to go shopping. 我真的不愿意去购物。

—So do I. 我也是。

(1)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,结构为“so + be /情态动词/助动词+主语”。如:

—They can swim well. 他们游泳很棒。 —So can we. 我们也游得很好。

(2)如果表示上文提到的否定情况也同样适合另外一个主体,则用neither/ nor + be/ 情态动词/ 助动词+ 主语。如:

—I don’t like the weather here. 我不喜欢这儿的天气。 —Neither/ Nor does she. 她也不喜欢。

2. But it seems that their living conditions were not very good. 他们的生活条件似乎不是很好。 seem是系动词,后接形容词构成系表结构;seem to后接动词原形,意为“似乎”,表示推测;It seems后接that从句,表示“似乎,好像??”。如:

But the problem of China’s population still seems quite serious. 但是中国的人口问题似乎仍很严重。 The rainbow seemed to end on the hillside. 彩虹好像一直延续到山坡为止。 It seems that it is going to rain. 好像要下雨了。

3. At that time, China had the largest population in the world and it was not well developed. 那时,中国有世界上最多的人口,而且经济也不发达。 population是名词,可以用large/ big/ small等形容词修饰;population作主语时,谓语用单数形式;针对人口数量提问时,特殊疑问词用what。如

What’s the population of China? 中国有多少人口?

China has a population of about 1.3 billion. 中国大约有13亿人口。

4. Because of our country’s one-child policy, now most families have only one child. 因为我们国家的独生子女政策,现在大部分家庭只有一个孩子。 because of介词短语,意为“因为,由于”。如:

He walked slowly because of his bad leg. 他因为腿不方便而行走缓慢。

5. Er, I don’t think that’s good. 嗯,我认为那不好。 当think, believe, suppose, imagine, expect等动词后接的宾语从句中含有否定意义,一般要把否定词转移至主句,即否定主句的谓语动词。此现象称为否定转移。如:

I don’t think it will rain tomorrow. 我认为明天不会下雨。

I don’t believe he treated the child like that. 我相信他不会那样对待孩子的。

Section B

1. And it is increasing by 80 million every year. 世界人口在以每年八千万的幅度增长。 increase by 增加了,增长了 如:

The price of oil increased by 2%. 石油的价格增长了百分之二。

2. It shows that the population in developing countries is larger than that in developed countries, doesn’t it? 它(图表)表明了发展中国家的人口比发达国家的更多,对吗? developing countries 发展中国家 developed countries 发达国家

3. So it is. 的确是,是这样。 so + 代词/名词+助动词/be 动词/情态动词,表示对上文情况的肯定、同意,意为“确实如此”。如: —John studies very hard. 约翰学习刻苦。

—So he does. 他确实刻苦。 —She can speak English. 她会说英语。 —So she can. 她确实如此。 Section C

1. … about one fifth of the people in the world live in China.

??世界上大约五分之一的人生活在中国。 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,分母的序数词变复数,直接在词尾加“s”。如:

2. So far, our government has taken many measures to control the population. 到目前为止,我们的政府已经采取了许多措施来控制人口的增长。 (1)so far到目前为止,迄今为止,通常与现在完成时连用。如:

We haven’t had any trouble so far. 迄今为止我们没遇到什么麻烦。 (2)take measures to do sth. 采取措施来做某事 如:

We must take stronger measures to protect our environment. 我们必须采取更有力的措施来保护我们的环境。

13 one third 12 a/ one half

25 two fifths 132 three and a half

3. One is known as the one-child policy. 其中一项措施是独生子女政策。 be known as…为固定短语,“将??称为,把??叫做”的意思。如:

The village was known as Garden Mill. 该村被称为米尔花园。

4. Thanks to the policy, China is developing quickly and people’s living conditions are improving rapidly. 由于计划生育政策,中国正在迅猛发展,人们的生活水平也正在迅速地提高。 thanks to介词短语,表示“幸亏??,由于??”。如:

Thanks to your help, I could finish my work. 多亏你的帮助,我才完成了我的任务。

Section D

I can’t go shopping in big stores unless I travel for a couple of hours. 我得花几个小时的时间才能到大的商场去购物。

unless连词,用于引导条件状语从句,意为“除非??,如果不??”,相当于“if…not”。如:

I can’t finish my work unless you help me. 除非你帮助我,否则我不能完成任务。
