高二英语教材重难点解析Unit1-2,http://www.170xue.com
-- ____?
A. What forB. What is it
C. How is itD. How come
[考查目标] 此题主要考查交际用语。
[答案与解析] A根据语境。答语中问的是目的。该句其实是个省略句，补全后的完整句子是：I go and empty that drawer for what。what提前构成疑问句就成了what for 或 for what。
☆词语比较☆
1. observe, watch
当“观察”来讲时，observe相当于watch carefully，尤其用于实验或研究等场合。具体来说，observe含有“察觉到”的意思，watch意为“盯着看”。
watch 还含有“观看(比赛、电视)”等，而observe没有此意。另外，watch还有“照料”之意，相当于take care of。还有“当心”之意，相当于be careful with。
She has observed the stars all her life.
她一生都在观察星星。
I'll watch the baby while you are away.
你不在时，由我照料你女儿。
You'd better watch Mr Smith, I think he is a thief.
你最好当心史密斯先生，我想他是个贼。
2. be known for, be known as, be known to
be known for 以……出了名 (通常不是指同位的关系)
be known as 作为……出了名 (通常加上职业名词，表同位关系)
be known to 为……所知

日本以它的汽车而闻名。
Luxun is known as a writer.
鲁迅作为作家很出名。
As is known to all, China has four famous invitations.
众所周知，中国有四大著名的发明。
3. elect, select, choose
elect 只能用于选举人，是投票选举的正式用语。
They elected Nixon President. 他们选尼克松为总统。
choose 可用于挑选人或物。

4. burn down, burn up, burn out
bum down 指“烧为平地，烧毁”；也指“火力减弱”。
The house was burnt down in an hour.
房子一小时被烧为平地。
bum up 有“烧旺”之意，也可指“消耗掉”。
You'd better put more wood on the fire to make it burn up.
你最好往火上添着柴，让它烧旺。
bum out 指“火熄灭”。

☆精典题例☆
()1. The news reporters hurried to the airport, only ____ the film stars had left. (2004 福建)
A. to tellB. be told
C. tellingD. told
【解析】选B该题考查不定式做结果状语的用法。不定式前有only，just等词，后跟不定式通常表结果。又因为记者们应该是被告知，所以用不定式的被动式。
()2. Having been in bed for nearly a month, they
had a hard time ____ the exam. (2004福建)
A. passB. to pass
C. passedD. passing
【解析】选D该题考查句型 have a hard time (in)doing。
()3. He hasn't slept at all for three days. ____ he is tired out. (2005 湖北)
A. There is no pointB. There is no need
C. It is no wonderD. It is no way
【解析】选C依题意“他三天没睡，难怪他累极了。”There is no point in doing sth. 是本单元的句型，意为：做某事没有作用或意义；而There is no need in doing sth. 没有必要做某事；It is no wonder 没什么大惊小怪；It is no way没可能。
()4. The disc digitally ____ in the studio sounded fantastic at the party that night. (2004上海)
A. recordedB. recording
C. to be recordedD. having recorded
【解析】选A通过分析句子，该题句子的谓语显然是sounded，因此recorded只能是非谓语，所以选A，考查过去分词在句中做定语的用法，recorded 相当于 which was recorded。
()5. ____ I know the money is safe, I shall not worry about it. (2003北京)
A. Even thoughB. Unless
C. As long asD. While
【解析】选C句意为“只要我知道钱是安全的，我就不会担心。”even though“即使”；unless“除非”；while“当……时候”，它们都同句意不吻合。
()6. We were swimming in the lake ____ suddenly the stoma started. (2004北京春季)
A. whenB. while
C. untilD. before
【解析】选A该题考查连词的用法。该句的意思是：当我们正在湖里游泳的时候，突然暴风雨开始了。when表示“这时(突然)”的意思，这种用法when一般放句末。
()7. Oil prices have risen by 32 percent since the start of the year, ____ a record US$57.65 a barrel on April 4. (2005山东)
A. have reachedB. reaching
C. to reachD. to be reaching
【解析】选B分词在句中做结果状语，可参见本单元的句型6。
()8. ____ the pot for me, and don't let the milk come out. I'll be back soon.
A. ObserveB. Notice
C. WatchD. Look out
【解析】选Cwatch 表示集中精力“照料，监视”，本句意为“帮我看着壶，别让牛奶溢出来。”；observe意为“观察”，表示动作；Notice指“注意到”表示结果；look out后面不能接宾语。
