 6.—What do you think is the fastest way to travel?
    —I think the fastest way to travel is by plane.
三、语法
 宾语从句
 1.学习和掌握由连词that引导的宾语从句(that在口语中常被省略)。
 2.学习和掌握主句是一般现在时或一般过去时态,宾语从句的动词应使用的时态。
知识梳理
1.Could/Can/May I speak to..., please?我能和……通话吗?
打电话时,若要对方等候时可以说:hold on别挂断,Hold on for a moment, please .请稍等一下。若要找的人不在,可以说I'm sorry he/she isn't here right now.很抱歉他/她现在不在(“不在”还可以说:is out/isn't at home等;“现在”还可以说:at the moment, now等)。以上是打电话用语。又如:Who's that (speaking)?请问你是谁?This is Mary(speaking).我是Mary。Is that Lin Tao(speaking)?你是林涛吗?Yes, speaking.是   的,我是。
2.关于as...as possible
 as soon as possible意为“尽快”。例如:
 We'd better finish our work as soon as possible.我们最好尽快完成工作。
 可以将soon换成其他副词,意思是“尽可能…”,如:
 Can you say it as loudly as possible? 你能尽可能大点声音吗?
 He tried to write as carefully as possible.他试着尽可能仔细地写。
 3.在His train ride seemed really short中,动词seem为系动词,seem作系动词时,其常见的句式为:
 ①seem+形容词。如:
 He seems much better this morning.他今天早上看上去好多了。
 ②seem+to do。如:
 You don't seem to be quite yourself today.你今天好像不大对头。
 ③seem+that从句。如:
 It seems that I have seen him.我好像见过他。
4.学习宾语从句,要从以下三个方面来掌握:
①引导词:本单元学习的引导词是that。宾语从句是陈述句时用that引导,that常可省。如:I think (that)I can do it.
 ②语序:宾语从句必须用陈述句语序。如:I know what they are doing.
③动词的时态:主句的动词如是现在时态,宾语从句中动词可以根据实际的情况用不同的时态,如一般现在时,一般过去时,现在完成时,一般将来时。如:
 I see you are on foot today.
 I hope she didn't hurt herself.
 I think I've lost it.
 We hope you'll have a very happy year in our class.
 主句是一般过去时,宾语从句须用表示过去的某种时态。如:
 His teacher told him that Jim was away on a trip.
 He said that he had travelled around the world.
如果宾语从句的内容表示的是客观真理时,宾语从句后谓语动词不受主句谓语动词时态的影响,应保留一般现在时态形式。如:
 The teacher said the earth goes around the sun.
 5.It is much cheaper and far more enjoyable that a rushed trip by air.它(乘火车旅行)行匆匆忙忙地乘飞机旅行相比要便宜得多,而且享受的乐趣也大得多。
 much, far用在比较级前,表示“……得多”。又如:
 It is much colder today than yesterday.今天比昨天冷得多。
6.offer v.提供,建议;出售
 I offered a new plan and everyone agreed about it.
 我提出了一个新计划,每个人都同意。(offer+n.)
 We offered to help you.我愿意帮助你们。(offer+to do)
 The boss offered our school a car.
 那位老板提供给我们学校一辆小汽车。(offer+sb. +sth.)
 I offered him the computer for 2000 yuan.
 我开价两千元把那台电脑卖给他。(offer sb. sth. for)
7.keep doing sth.不断,一直,老是做某事(连续不断地或反复地发生)。
 a)keep on doing sth.不断,老是做某事;继续做某种(动作之间略有间隔)。
 The headmaster kept talking for nearly an hour.
 校长持续谈了近一个小时。
 You shouldn't keep thinking about it.你不应该老想这事。
 b)keep+sb.+doing使继续处于某种状态
 I'm sorry to have kept you waiting for so long.对不起,让你久等了。
8.关于none
none意为“(三个以上)一个也不”,是表示否定的不定代词,可代替人也可代替物。我们可以把none看成是all的反义词。例如:
 All of the students went to see the film, but none of them could understand it.
 所有的学生都去看了电影,但没有一个人能看得懂。
None或none of做主语时,谓语动词可用单数也可用复数。当表示“所有的人(或物)都不”的时候,一般用复数形式,当表示“其中一个人(或物)也不”的时候,则一般用单数形式。例如:
 None of the things they said were new to me.他们说的事情对我来说都不是什么新闻。
 None of his friends has ever been to Seattle.他的朋友中一个也未曾去过西雅图。
9.such,quite和very
 such修饰可数名词单数,不定冠词放such和名词之间,这点和quite类似。例如
 The foreigners never think Hang zhou is such a beautiful city.
 外国人怎么也想不到杭州是如此美丽的一个城市。
 The Smiths live in quite a small house.史密斯住在一个相当小的房子里。
 但如果换成very的话,不定冠词要放在very的前面。
 Yesterday I saw a very interesting film.昨天我看了一个非常有趣的电影。
