沿湄公河而下的旅程
第一部分 梦想与计划
我的名字叫王坤。从高中起，我姐姐王薇和我就一直梦想作一次伟大的自行车旅行。两年前，她买了一辆昂贵的地自行车，然后还说服我买了一辆(地车)。去年，她去看望了我们的表兄弟——在昆明读大学的刀卫和宇航。他们是傣族人，在云南省西部靠近澜沧江的地方长大，湄公河在中国境内的这一段叫澜沧江，在其他国家(境内)叫湄公河。很快，王薇使表兄弟也对骑车旅游也产生了兴趣。大学毕业以后，我们终于有了机会骑自行车旅行。我问我姐姐：“我们要去哪儿？”首先想到要沿湄公河从头到终点骑车旅游的是我的姐姐。现在她正在为我们的旅行制定计划。
我很喜欢我姐姐，但是她有一个很严重的缺点。她有时确实很固执。尽管她对去某些地方的最佳路线并不清楚，她却坚持要自己把这次旅游安排得尽善尽美。于是，我就知道这个尽善尽美的方式总是她的方式。我不停地问她，“我们什么时候出发？什么时候回？”我还问她是否看过地图。当然她并没有看过——我的姐姐是不会考虑细节的。于是，我告诉她，湄公河的头在青海省。她给了我一个坚定的眼神——这种眼神表明她是不会改变主意的。我说，我们的旅行将从5 000多米的高地出发，这时她似乎显得很兴奋。当我告诉她那里空气稀薄，呼吸困难，而且天气很冷时，她却说这将是一次有趣的经历。我非常了解我的姐姐，她一旦下了决心，什么也不能使她改变。最后，我只好让步了。
在我们旅行前的几个月，王薇和我去了图书馆。我们找到一本大型地图册，里面有一些世界地理的明细图。我们从图上可以看到，湄公河发于西藏一座上的冰川。起初，江面很小，河水清澈而冷冽。然后它开始快速流动。它穿过深谷时就变成了急流，流经云南西部。有时，这条江形成瀑布，进入宽阔的峡谷。我们俩惊奇地发现这条河有一半是在中国境内。当流出中国，流出高地之后，湄公河就变宽了，变暖了，河水也变成了黄褐色。而当它进入东南亚以后，流速减缓，河水蜿蜒缓慢地穿过低谷，流向生长稻谷的平原。最后，湄公河三角洲的各支流流入中国南海。

1．The new railway winds its way to Hong ong，________the mountains, ________ the tunnels and ________ the rivers.

C．over；through；across D．through；over；across

2．________ others say，the professor is sure that his theory is correct.
A．No matter B．It doesn’t matter
C．Whatever D．What
答案 C
解析 whatever others say是whatever引导的让步状语从句。whatever既可以引导让步状语从句，也可以引导名词性从句。A选项应改为No matter what才正确。
3．I ________ him not to smoke，but he didn’t think it necessary.
A．persuaded B．advised C．hoped D．suggested
答案 B
解析 此题考查这四个单词的意义及用法，hope和suggest后均不能跟复合宾语即“动词＋宾语＋不定式(作宾语补足语)”，因此C、D两选项错误。而persuade sb.to do sth.意为“说服某人做某事”，不符合题意。故选B项。
4．The boy insisted that he ________ the money and that he ________ at once.
A．not steal；be set free B．hadn’t stolen；be set free
C．didn’t steal；should be set free D．hadn’t stolen；set free
答案 B
解析 insist这个词如果表示“坚决要求做某事”，从句谓语动词要用(should) do；如果表示“坚决认为某一观点、主张”时，从句的谓语动词应用与主句相应的某种时态。
5．I don’t know ________ I should go away.
A．which B．if or not C．whether or not D．where
答案 C
解析 首先根据句意排除A、D两选项；“whether or not I should go away”是以whether引导的一个宾语从句，whether可以和or连用，而if不能。
6．________ you understand this rule，you will have no further difficulty.
A．Once B．Unless C．Until D．Till
答案 A
解析 根据句意排除B选项；而C、D两选项又不符合英语的习惯，故选A项。
7．He didn’t give in ________ the enemy even under death.
A．for B．with C．to D．on
答案 C
解析 give in作“屈服；让步”解时是不及物动词，若表示“向……屈服/让步”，用“give in to...”。
8．r.Hall understands that ________English has always been easy for him，it is not easy for the students.
A．unless B．since C．although D．when
答案 C
解析 该题考查连接词的用法。“r.Hall understands”是主句，其后是that引导的宾语从句，English has always been easy for him 与it is not easy for the students之间为转折关系，故选C项。
9．Was it last week ________ we sold our old car to a exican?
A．when B．that C．which D．what
答案 B
解析 本句为强调句型的一般疑问句形式，强调的是时间状语last week。根据强调句结构“It is/was...that...”判断，此处应填that。
10．I tried to ________ give up the foolish idea，but hewouldn’t listen to me.
A．advise him to B．persuade him to C．advise him into D．persuade him into
答案 B
解析 考查短语persuade sb. to do sth.(说服某人做某事)的用法。
11．He ________ to go into business when he leaves college.
A．has made up his mind B．has kept his mind
C．made up his mind D．kept his mind
答案 A
解析 make up one’s mind意为“下定决心”，根据时间状语从句“when he leaves college”判断此处应用现在完成时。
12．She loved acting in films，so after ________ high school，she went to study at a famous drama school.
A．graduated at B．graduated in
C．graduated from D．graduated as
答案 C
解析 “从……(学校)毕业”用graduate from表示。
13．Finally he got the job he ________ .
A．dreamt about B．had dreamt about
C．dreamt for D．had dreamt for
答案 D
解析 dream for意为“梦想；向往”；dream about没有这个意思。由“Finally he got...”的时态可判断应用过去完成时。
14．He left the place，________ never to come back.
A．determined B．determining
C．being determined D．having determined
答案 A
解析 “determined...”作伴随状语，意为“有决心的；坚决的；坚定的”。
15．—Thank you for the lovely party and the delicious food.
—________.
A．Thanks，too B．Never mind
C．All right D．y pleasure
答案 D
解析 此题考查对感谢的回答。“y pleasure.”意为“不用谢；乐意效劳”，相当于“It’s my pleasure.”。
