Section I  课前准备、听力、口语

1. What will life be like in the future? 未来的生活会是什么样子? (p.41 Warming Up)

What ...like? “……像什么/怎么样/什么样子?”，此处like是介词，其宾语是what。

如：① What's the weather like there? 那儿的天气怎么样?

② What's your teacher like? 你老师是怎样一个人?

2. What happened to the people on the earth? 地球上的人出什么事了? (p.42 Listening Ex.3)

happen to“某人/某物发生了什么事，怎么了”。

如：① That autumn something unfortunate happened to my family. 那年秋天，我家发生了一件不幸的事。

② What finally happened to the poor boy? 这可怜的男孩最后怎么了?

③ What has happened to your leg?你的腿怎么了?

④What has happened to the recorder?录音机怎么了?

3. It would be wonderful if (I had more free time)! 假如 (我有更多的自由时间)，那该多好啊! (p.43 Useful expression_rs)

什么是虚拟语气?虚拟语气表示说话人的主观愿望、猜测、建议或与事实不符的假设等，也可以表示可能性较小或不可能发生的情况，虚拟语气常用于复合句中。上句是一个含有条件状语从句的复合句，主句和从句的谓语动词使用了虚拟语气，表示“与现在事实相反的”一种假设。那么，当说话人想表示“与现在事实相反的”假设时，主句和条件状语从句的谓语动词的“模版形式”是怎样的呢?请观察如下，

如：① If I were you, I wouldn't accept her suggestion. 如果我是你，我不会接受她的建议。

② If I knew the answer to the question, I should (would) tell you. 如果我知道问题的答案，我会告诉你的。

③ If he were here, he might talk with you. 如果他在这儿，他可能会跟你谈谈的。

④ If I didn't do exercise every day, I wouldn't be so strong. 如果我不每天锻炼，我是不会这么强壮的。

4. One way to catch a glimpse of the future is to examine some of the major trends in contemporary society. 瞥一眼未来是什么样子的办法之一是考察一下当今社会的主要倾向。(p.43 Reading ‘Life in the future’ 第2行)

(1) to catch a glimpse意为“看一眼;瞥见”。在句中作one way的定语;

to examine some of the major trends in contemporary society作表语。

① I caught a glimpse of our new neighbor. 我只看过一眼我们的新邻居。

② I glimpsed her among the crowd. 我瞥见她在人群当中。

③ The man glimpsed the thief climbing out of the window. 那人瞥见小偷从窗户爬出来。

5. A good example of how transportation is changing is the new maglev train，which is environmentally friendly, energy-saving and travels at an amazing speed of 430 km/h. 交通工具是如何变化的一个很好的例子就是新兴的磁悬浮火车，这种火车既友好于周围环境，又节能，并且以每小时430公里的惊人速度行驶。(p.43 Reading ‘Transportation’ 第4行)

(1) 句中how transportation is changing (交通工具是如何变化的) 作介词of的宾语从句;which is…and travels…430 km/h是限制性定语从句，其先行词是train。amaze (vt.) 使惊奇，使吃惊;amazing (adj.) 令人惊异的;amazed (人) 惊异的，惊愕的。如：

① Her knowledge amazes me. 她的学识令我吃惊。

6. Many companies and consumers have already begun reforming the way they do business. 许多公司 和消费者已经开始改革他们之间的交易形式。(p.43 Reading ‘Business’ 第1行)

(1) reforming the way they do business是动名词短语作宾语。动词begin的宾语也可用不定式，可改为…begun to reform the way they do business;they do business作名词way的定语从句。

☆reform ( n. & v.)改革，改进，悔改。

如：① The reform and open policy has brought us Chinese people a rich and colourful life. 改革开放的政策给我们中国人民带来了富裕和丰富多彩的生活。

② We must reform the outdated rules and regulations. 我们必须改革那些过时的规章制度。

③ He promised to reform if given another chance. 他答应只要再给他一次机会就一定悔改。

(2) 名词way(方法)后面的定语从句的关系词可用that代替in which，也可以如上句一样不用任何关系词。再如：

① They way(that/in which)you're doing is completely crazy. 你这么干法，简直是发疯了。

② I liked the way(that/in which)she organized the meeting. 我喜欢她组织会议的方法。

【拓展】

in this/that/the way中的介词常可省略;way后既可跟“带to的动词不定式”结构作其定语，也可跟“of + -ing”结构作其定语，两者之间没有多大的区别;另外，不要混淆in the way(挡道)，on the way (在途中)和by the way(顺便说)。请看如下例句：

① I think you're putting it together (in) the wrong way. 我认为你把它装错了。

② Do it any way you like. 你爱怎么干就怎么干。

③ There was no way to prove that he stole the money. 没有办法证明他偷了钱。

④ There was no way of proving that he stole the money. 没有办法证明他偷了钱。

7. E-commerce, or business done on the Internet, is becoming more and more popular. 电子商务，或者说在因特网上所进行的贸易，越来越受到人们的青睐。(p.43 Reading ‘Business’ 第2行)

此处or的意思是“或者说，也就是”。注意下面与or搭配的词组：or else ( = otherwise) 否则，要不然;or so大约;or rather或者说，更准确地说;or sb. (sth./sp.)或者其他什么人(其他什么东西，其他什么地方)。

如：① This medicine, or rather drug, has a violent effect.这种药品,或者说麻醉剂，有强烈的效果。② Hurry up, or (else) you'll miss the bus. 快点，否则你就赶不上公共汽车了。

③ He must pay off the debts or else go to prison. 他必须还清欠债，否则就得去坐牢。

④ I'd like twenty or so. 我想要20个左右。

⑤ I put it in the cupboard or somewhere else. 我把它放到橱柜里，或者其他什么地方。

8. The Internet also makes it easier for companies to keep in touch with customers and companies in other countries. 因特网也使公司和消费者及国外其他公司之间的联系更加容易。(p.44 Reading ‘Business’ 第3行)

(1) it为形式宾语，easier为宾语补足语，真正的宾语是动词不定式复合结构for companies to keep in touch with customers and companies in other countries。

词组keep/be in touch with…意为“与……保持联系”;get in touch with ...“和…取得联系”;

lose touch with ...“与…失去联系”;out of touch“失去联系，对…生疏”。

如：① I still keep in close touch with most of my high school classmates. 我仍然和大部分中学同学保持着紧密的联系

② I'll get in touch with you as soon as I arrive. 我一到达，就跟你联系。

③ We've been out of touch with them for ages. 我们好多年没联系了。

(2) 关于动词不定式复合结构：如果不定式的逻辑主语既不是句子的主语，也不是谓语动词的宾语，就要用"for + n./pron.”作为它的逻辑主语。

如：① It is difficult for her to read the book. 她读这本书是困难的。

② It's quite necessary for you to give up smoking. 你很有必要戒烟。

【提示】在“It is + adj. + of + n./pron. + to do”结构中，of前面的形容词一般限于对of后面的名词表示称赞和责备(即此入的品质)的形容词。如：nice, clever, bold, honest, polite, careful, wrong, bad, rude, stupid, silly, careless, foolish, naughty 等。

如：① It's clever of you to refuse her. 你拒绝她是明智的。

② It's cruel of him to kill the cat. 他把那只猫杀死，太残忍了。

9. Instead of just searching a crowded store for basic goods, such as food and clothes, people want to go to a pleasant mall and combine shopping with fun. 人们现在想去的购物商场是令人感到舒服的，并且是寓购物于娱乐中的，而不再是像以前那样，穿梭于拥挤的商店中，寻找着诸如食品和衣物一类的日用品。(p.44 Reading ‘Business’ 第7行)

(1) instead of (= in place of/rather than) prep. 代替，而不是…。如：If you cannot go, he'll go instead of you. 如果你不能去，他愿替你去。

如：① He searched all the drawers for the missing papers. 他翻了所有的抽屉，找那份丢失的文件。

10. People in the future will be able to enjoy a longer and healthier life and remain active even in old age. 未来的人们将能够更长寿、更健康，即使年龄很大，也会很活跃的。(p.44 Reading ‘Health And Medicine’ 第1行)

remain active为系表结构，remain在此是系动词，意为“保持，依然，仍然，继续”。另外remain也是一个不及物动词，意为“留下，剩余，残存”。

It remains to be seen…句型，意为“……还要看情况发展”。
