二、考查定语从句中的“介词+关系代词”结构
1、考查该结构中关系代词的选用。若介词放在关系代词之前,关系代词指人时常用whom,指物时常用which。
[典型考题]
①(09海南)She brought with her three friends, none of I had ever met before.
A. them B. who C. whom D. these
②(10江苏)The newly built café, the walls of_______ are painted light green, is really a peaceful place for us, specially after hard work.
A. that B. it C. what D. which
解析:①C。在定语从句中代替先行词friends作介词of的宾语。故用关系代词whom。②D。在定语从句中先行词the newly built café作介词of的宾语。故用关系代词whom。
2、考查该结构中介词的选用。
(1)一般来说,确定关系代词前的介词,可以从以下三方面入手:先行词的意义;从句中的动词固定搭配;句子的意思。
[典型考题]
①( 08上海)We went through a period communications were very difficult in the rural areas.
A.which B.whose C.in which D.with which
②(10山东) Wind power is an ancient source of energy we may return in the near future.
A. on which B. by which C. to which D. from which
③( 06陕西)She was educated at Beijing University, she went on to have her advanced study abroad.
A. after which B. from which C. from that D. after that
解析:①C。把从句补充完整:communications were very difficult in the rural areas in/during the period,可以判断出此处用介词in。此句中介词的选用取决于先行词period。②C。把从句补充完整: we may return to an ancient source of energy in the near future,可以判断出此处用介词to。此句中介词的选用取决于从句中的动词固定搭配return to sth.。③A。主句与定语从句是先后关系,故用after which。。此句中介词的选用取决于句子的意义
(2)表示“整体和部分关系”、“同位关系”或“所属关系”,介词常用of。常见结构:(I)在some, any, few, little, none, all, both, neither, many, most, each等代词或数词的前后可以用of which/whom。(II)the +比较级或最高级前后用of which/whom等。
[典型考题]
①( 05全国I)I have many friends, some are businessmen.
A. of them B. from which C. who of D. of whom
②(04湖北)There are two buildings , stands nearly a hundred feet high .
A.the larger B.the larger of them
C.the larger one that D.the larger of which
解析:① D。先行词friends在定语从句中与some构成所属关系,故用some of whom或of whom some。②D。先行词buildings在定语从句中与比较级the larger构成所属关系,故用the larger of which或of which the larger。
