高考英语定语从句考点
一、考查关系代词that和 which的区别
1．Finally ，the thief handed everything _____ he had stolen to the police．（MET'87）
A．which B．what C．whatever D．that
2．All _____ is needed is a supply of oil．（MET'89）
A．the thing B．that C．what D．which
答案及简析：
1．D。2．B。that和which都能指物，在定语从句中作主语或宾语，但下列情况下，常用that，不用which：①先行词是all， everything，anything，nothing等不定代词。②先行词指物且被形容词最高级、序数词或all，no，only，the very，the last等修饰。③先行词既指人又指物。
二、考查关系代词whose
3．A child _____ parents are dead is called an orphan．（MET'86）
A．which B．his C．whose D．with
答案及简析：
3．C。关系代词whose在定语从句中作定语，修饰其后的名词，意为“……的”。有时“whose ＋n．”可转换为“n．＋of＋which ／whom”。如：
The building whose roof（＝the roof of which）we can see from here is a hotel．
This kind of book is for the students whose native language（＝the native language of whom）isn't English．
三、考查关系代词与关系副词的差异
4．After living in Paris for fifty years he returned to the small town _____ he grew up as a child．（NMET'96）
A．which B．where C．that D．when
5．I also enjoyed the evenings when we spent together．（NMET'95短文改错）
答案及简析：
4．B。5．去掉when或when→that／which。如何选用关系代词和关系副词呢？关键是看先行词在定语从句中作什么成分。决不能只按先行词是地点名词就用 where，先行词是时间名词就用when，先行词是reason就用why。有时，命题者还会在先行词与引导词之间加入附加成分，影响考生正常解题思路，做题时，要特别注意。
四、考查“介词＋关系代词”
6．He paid the boy ＄10 for washing ten windows， most of _____ hadn't been cleaned for at least a year．（MET'90）
A．these B．those C．that D．which
答案及简析：
6．D。“介词＋关系代词”引导的定语从句，关系代词一般只有which，whom。先行词是物时，用which，先行词是人时，用whom。介词的选定一般依据下列三点：①看定语从句中的形容词与哪一个介词组成固定搭配②看先行词与哪一个介词组成习惯搭配③看定语从句中的动词与哪一个介词组成习惯搭配。
五、考查非限制性定语从句与限制性定语从句的区别
7．Dorothy was always speaking highly of her role in the play，_____ ，of course，made the others unhappy．（NMET2000）
A．who B．which C．this D．what
8．I shall never forget those years _____ I lived in the country with the farmers，_____ has a great effect on my life．（上海94）
A．that；which B．when；which C．which；that D．when；who
答案及简析：7．B。8．B。原因见本期第2面。
六、考查as引导的非限制性定语从句
9．_____ is known to everybody，the moon travels round the earth once every month．（NMET2001）
A．It B．As C．That D．What
答案及简析：
9．B。as，which均可用来引导非限制性定语从句，代替整个主句，但as引出的从句可放在句首、句中或句末，which引出的从句通常只能放在主句后面。
