针对20-21单元所学内容，我们总结、归纳了如下八个重点词语的用法，并结合考题作了解析。不妨看看，是否说到你的心里去了--

　　1. intend vt. 想要；打算；意指

　　[典型考题]

　　She intended ________ but the look on your face suggested "No".

　　A. she explaining B. to explain

　　C. explanation D. to be explained

　　[考点解析]答案：B。intend后面既可以跟动词不定式也可以跟动名词，还可以跟that从句，但动词不定式表示"将要"，根据题意，所以选B。

　　2. certain adj. 确定的；无疑的；某(种)

　　[典型考题]

　　It isn't quite ________ that he will be present at the meeting.

　　A. sureB. rightC. certain D. exact

　　[考点解析]答案：C。一般情况下sure与certain可换用。但用it作形式宾语或形式主语，that从句作真实主语或真实宾语时，只用certain，不用sure。

　　3. appreciate vt. 赏识；鉴赏；感激

　　[典型考题]

　　I would appreciate ________ back this afternoon.

　　A. you to call B. you call

　　C. your calling D. you're calling

　　[考点解析]答案：C。appreciate后面要跟名词或动名词。

　　4. suffer vi. 经历或遭受；忍受

　　[典型考题]

　　In the old days the poor suffered greatly

　　________ having inadequate clothing and no food.

　　A. from B. inC. of D. on

　　[考点解析]答案：A。suffer from是固定搭配，意为"受……之苦；患……"。

　　5. fortunately adv. 幸运地

　　[典型考题]

　　I was late in getting to the station, but

　　________ the train was late too.

　　A. fortunate B. fortunately

　　C. being fortunate D. being fortunately

　　[考点解析]答案：B。根据题意，此空应用副词，故选B项。

　　6. avoid vt. 避免；消除

　　[典型考题]

　　I want ________ her again.

　　A. avoiding meetingB. to avoid meeting

　　C. avoiding to meet D. to avoid to meet

　　[考点解析]答案：B。want后跟带to的不定式，而avoid后要跟V-ing形式，所以选B。

　　7. manage vt. & vi. 做成(某事)；管理；经营

　　[典型考题]

　　You might wonder how it ________ to live without eating for so many months.

　　A. keepsB. succeeds

　　C. manages D. tries

　　[考点解析]答案：C。A、B项后面不能接不定式；从句意可知，它指的是"成功地活下来"，故答案为C。try to指"设法做某事，但不一定成功"。

　　8. occur (occurring; occurred; occurred) vi. 发生；出现； 想到

　　[典型考题]

　　It suddenly ________ me that I would have to arrive by 5 o'clock, and it was 6 o'clock now.

　　A. occurred toB. occurred

　　C. took place D. happened

　　[考点解析]答案：A。表示"在脑海中出现某种想法"时，应使用occur，而不用happen。又因occur, take place和happen都是不及物动词，后面不能直接跟宾语，所以只有A项正确。该句意思是"我突然想起我应该五点前到，而现在已经六点了"。
