[牛刀小试2]

☆句型归纳☆

1. You shouldn't go rafting unless you know how to swim, and you should always wear a life jacket. 除非你会游泳,而且要一直穿着救生衣,否则就不应该去做漂流运动。

该句中的unless引导状语从句。例如:One can't learn a foreign language well unless he studies hard.

unless引导的条件状语从句,一般可以与if...not...互换。还要注意unless引导的从句经常可以省略。

【考例】(200l北京春招)The men will have to wait all day ____ the doctor works faster.

    A. if    B. unless    C. whether    D. that

[考查目标]状语从句。

[答案与解析]B  句子意思是“如果医生不快点工作,

这些人将不得不等一整天。”应该选unless。

 
 

2. Eco-travel is a way to find out what can be done to help animals and plants as well as people. 生态游可以找到既帮助别人.又帮助动植物的途径。

该句中的as well as是连词,连接两个并列成分。例如: He can speak German as well as French.

常见的用法:

1. well是副词,意思是“好,优秀”,as well as是形容词  同级比较结构。

2. as well as是固定短语,意思是“和”,相当于"not only … but also..."。

3. as well as连接两个并列成分作主语时,句子的谓语动词应该与前面那个名词或代词的人称或数保持一致。

4. as well as还可当作复杂介词用,意思是“除了……之外,还有”;相当于"besides,apart from"。

5. as well,是副词短语,意思是“也”,相当于“too / also”常位于句尾,与too位置相当。

6. may / might as well do sth 表示“还是……的好”。

【考例】(NMET 1994) John plays football ____, if not better than David.

A. as well   B. as well as   C. so well   D. so well as

[考查目标] as well as连接比较状语从句。

[答案与解析]B  该句中 if not better than相当于插入语,起干扰作用,如果不予考虑,原句就变成了同级比较结构 "John plays football as well as David"。

3. Before she could move,she heard a loud noise. 她还没有来得及动弹,就听见很响的声音。

However, before she could think twice, the water was upon her. 但还没有回过身来,洪水便逼近了她。

该两句中的before用作连词,后接时间状语从句。before用作连词,接时间状语从句时,表示“在……之前”。但在不同的语境中,往往有比较灵活的译法。例如: He knocked me down before he saw me. 他差一点把我撞倒,才看到我。

 
 

【考例】(2005广东) The American Civil War lasted four years the North won in the end.

    A. after    B. before    C. when    D. then

[考查目标] 时间状语从句的引导词选择。

[答案与解析]B   before 表示“直到……”。

4. Tree after tree went down, cut down by the water, which must have been three meters deep. 洪水想必深达三米,树一棵接一棵地倒了,被洪水冲断了。

该句中的must have been表示推测。例如:You look so tired. You must have stayed up last night.

情态动词may,might,most.can,could常用来表示推测。may,might,must多用在肯定句中,can,could多用在否定句和疑问句中。may,might,must,can,could后接动词原形表示对现在的推测;may,might,must,can,could后接have done。表示对过去的推测。例如:

You may be a professor. / She must have met a fairy.

【考例】(2005辽宁)This cake is very sweet. You ____ a lot of sugar in it.

    A. should put    B. could have put

    C. might put    D. must have put

[考查目标] 情态动词表示推测。

[答案与解析] D  前文说蛋糕很甜,由此可知一定是糖

放多了。对于过去的动作的推测应使用have done的

结构,所以应在B、D之间做选择,又因为could have

done表示本可以做而没有做,所以选择D。

5. ... she heard a loud noise,which grew to a terrible roar. ……她听见了很响的声音,接着就变成了可怕的隆隆轰鸣声。

该句中的which引导非限制性定语从句。例如:He bought some reference books, which were all about science. 他买了许多的参考资料.都是有关理科的。

which 作为关系代词.既可以引导限制性定语从句,也可以引导非限制性定语从句。例如:The train which left for Beijing pulled in on time. 前往北京的火车按时进站了。His dog, which was now very old, became ill and died.他的狗,现在老了,生病死了。

 
 

【考例】(2005浙江) Jim passed the driving test, ____ surprised everybody in the office.

    A. which    B. that    C. this    D. it

[考查目标]非限制性定语从句。

[答案与解析]A  which引导非限制性定语从句。指代

前面整个句子。that不能引导非限制性定语从句。
