  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

  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。
