先行词是“the World Food Programme”，“世界粮食项目”的目的之一是……，whose在定语从句中作定语，这里限定purposes，故选C。
句意：1963年联合国建立了世界粮食计划署，其目的之一就是为了缓解世界范围内的饥饿问题。
9. My eldest son, _______ work takes him all over the world, is in New York at the moment.A. thatB. whoseC. hisD. who【答案】B0322. I live next door to a couple ________ children often make a lot of noise.A. whoseB. whyC. whereD. which【答案】A【解析】试题分析：题目考查定语从句的关系词。
a couple是先行词，这对夫妻的孩子很吵，children和couple是所属关系，故用whose作定语，whose children 相当于the children of whom，故选A。
23.Many young people, most ______were well-educated, headed for remote regions to chase their dreams.A. of whichB. of themC. of whomD. of those【答案】C11.

使用定语从句，先行词是next week，定语从句中不缺少主宾表，缺少时间状语。
故选D。
0424.Opposite is St.Paul's Church,___you can hear some lovely music.A. whichB.thatC.whenD.where【答案】D【解析】试题分析：句意：对面是圣保罗教堂，在教堂里你能听到一些优美的音乐。
这是一个定语从句。
先行词是St. Paul’s Church，从句主谓宾成分完整，去掉空后依然是完整的句子，可推断出引导词在从句中作的是地点状语。
用where。
故选D。
14. He wrote many children’s books, nearly half of____ were published in the 1990s.A. whomB. whichC. themD. that【答案】B【解析】试题分析：句意：他写了许多儿童书籍，几乎一半在1990年左右出版。
先行词是books，定语从句中of缺少宾语，故选B项。
19. Creating an atmosphere employees feel part of a team is a big challenge.A. asB. whoseC. in whichD. at which【答案】C15 The boss of the company is trying to create an easy atmosphere ______ his employees enjoy their work.A. whereB. whichC. whenD. who【答案】A【解析】试题分析：句意：公司老板正尽力创造一种轻松的气氛，在这种气氛中，其员工喜欢他们的工作。
句中先行词为atmosphere，在从句中作地点状语，故用关系副词where。
根据句意可知选A。
15. As the smallest child of his family, Alex is always longing for the time he should be able to be independent.A. whichB. whereC. whomD. when【答案】D【解析】试题分析：句意：作为家里最小的孩子，Alex总是渴望他能够有独立的时间。
这里使用定语从句，先行词是the time，定语从句中缺少时间状语，用关系副词when，所以选D。
21.The number of smokers, _____ is reported, has dropped by 17 percent in just one year.A. itB. whichC. whatD. as【答案】D【解析】试题分析：句意：据报道，吸烟者人数仅（过去）一年就减少了17%。
as引导的非限制性定语从句位置灵活，可以置于主句的句首、句中或句末，指代的是整个一句话。
故选D项。
考生容易误选B项which，把逗号前面的the number of smokers看成先行词，后面非限制性定语从句用which引导。
殊不知，这里关系代词指代的是“The number of smokers has dropped by 17 percent in just one year.”整个一句话。
另外，as和which在定语从句都可以指代一句话，但前者有“正如……”的意思，后者则没有。
还可以抓住as is reported这一常用结构，类似的还有as isknown/expected/planned/mentioned/said等。
059. We’ll reach the sales targets in a month _______ we set at the beginning of the year.A. whichB. whereC. whenD. what【答案】A【解析】试题分析：题意：再有一个月就能完成年初制订的销售目标。
which指代targets, 在从句中充当set的宾语，排除B、C两项；D项只能引导名词性从句，而本题是一个定语从句，故选择A项。
26. I borrow the book Sherlock Holmes from the library last week, ______ my classmates recommended to me.A.whoB. whichC. whenD. Where【答案】B【解析】试题分析：本题考查定语从句，考查方式为选择连接词。
根据题干信息，定语从句的先行词为book,定语从句中缺乏宾语（我朋友推荐给我“书”），加之逗号后为非限制性定语从句，所以本题选B。
句意：上周我从图书馆借了《福尔摩斯》，这是我的同学推荐给我的。
10. A company ______profits from home markets are declining may seek opportunities abroad.A. whichB. whoseC. whoD. why【答案】B【解析】试题分析：这是一个定语从句，a company 是先行词，profit和a company 是所属关系，所以要用关系代词whose。
句意为：在国内市场利润减少的公司可能会寻求国外发展的机会。
故答案选B。
4. I now, we have raised 50.000 pounds for the poor children, ______ is quite unexpected.A. thatB. whichC. whoD. it【答案】B【解析】试题分析:前后两个句子中间没有连词，是逗号，故判断为非限制性定语从句，that和it不引导非限制性定语从句，排除AD选项。
who用来指代人，which 用来指代物或者句子，而在本句中关系代词指代前面句子内容，故答案选B。
句意：直到现在，我们已经为穷苦儿童筹集了50,000英镑，这真的出乎意料。
22. The book has helped me greatly in my daily communication, especially at work ________ a good impression is a must.A. whichB. whenC. asD. where【答案】D【解析】试题分析：考查定语从句用法。

►He told me everything that he knew.他告诉了我他知道的一切。
2．先行词被all, any, every, each, little, no, some, much, the very, the only等修饰时。
►This is the very book that I am looking for.这正是我在找的那本书。
3．先行词是序数词或形容词最高级或被序数词、形容词最高级修饰时。
►This is the best film that I have ever seen.这是我曾看过的最好的电影。
4．先行词中既有表示人又有表示物的名词时。

4.定语从句中“介词＋关系代词”介词的确定。
5. which/ as引导的非限制性定语从句的区别。
一、定语从句的分类限制性定语从句定语从句非限制性定语从句二、限制性定语从句和非限制性定语从句的区别区别一：形式不同限定性定语从句主句和从句之间不用逗号隔开；而非限定性定语从句与主句之间通常____用___逗号隔开。
区别二：功能不同限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意____不明确___；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意不影响。
如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。
(若把从句去掉句子就失去意义)His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。
(若把从句去句子意义仍然完整)比较下面的两个句子：I have a sister who is a doctor. 我有一个当医生的姐姐。
(姐姐不止一个)I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。
(只有一个姐姐)区别三：翻译不同在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。
如：He is the man whose car was stolen. 他就是汽车被窃的那个人。
I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。
