SectionA
prefer vt.“更喜欢”(=like...better)的用法(注：过去式为preferred现在分词为preferring。)
练习：
( )1.—What a heavy rain!
—Soit is.I prefer ______ rather than _____ smilieid="3" border="0" alt="" />oyou know the man whois talking with your mother?其中划线部分为定语从句。
分类：（限制性）定语从句和非限制性定语从句。另外还有一种定语从句是间隔性(分隔性)定语从句。
(限制性)定语从句和非限制性定语从句的区别：
（限制性）定语从句无逗号隔开、不可缺少、起修饰限制作用；而非限制性定语从句有逗号隔开、可
有可无、起补充说明作用。
eg:①Thisis the school (that/which)we visited last year. （______________）
②Iwas the smilieid="3" border="0" alt="" />oyou have anything that you want to say for yourself?
（2）当先行词既有人又有事、物时。
eg:Doyou know the things and the persons that they are talking about?
（3）当先行词含有序数词或最高级时。
eg:①Thisbus is the first that will go to Beijing.
②Thisis the best movie that I have ever seen.
（4）当先行词被only、very、next、last等修饰时。
eg:Thisis the very book that I’m looking for.
（5）在who或which引导的特殊疑问句中。
eg:Whichis the bike that you lost?
（6）当关系代词在定语从句中作tobe的表语时。
eg:Zhengzhouis no longer the city that it used to be.
六．先行词为事/物时，引导词只用关系代词which的情况。
（1）引导非限制性定语从句时。
eg:Heturned out to be a very successful man,which was more than weexpected.
（2）当“介词+关系代词”结构引导定语从句时。
eg:Thisis the question about which they have had so much discussion in thepast few weeks.
（3）当关系代词后有插入成分时。
eg:①Ihave received your letter which,as I have told you,is badly needed bythe press.
②Marywas much kinder to Jack than she was to the others, which, of course,made all the others upset.
（4）当句子中有两个定语从句时，避免引导词重复。
eg:Theysecretly built a factory which produced things that could producepollution.
（5）当先行词为that时，引导词只用which且不可省略。
eg:Theclock is that which tells the time.
七．先行词为人时，引导词只用关系代词who(m)的情况。
（1）引导非限制性定语从句时。
eg:Shehas a daughter,who is a doctor in the famous hospital.
（2）当“介词+关系代词(宾格形式)”结构引导定语从句时。
eg:The gentleman about whom you told me proved to be a thief.
（3）当关系代词后有插入成分时。
eg:Thisis my friend who,I think,is the best in our class.
（4）当句子中有两个定语从句时，避免引导词重复。
eg:Wemet Tom who was a college student that won the first prize in theworld maths competition.
在There be句型结构中，且先行词指人时。
eg:Thereis a young lady who asks for you.
八．whose的用法
whose引导定语从句时必须和名词放在一起。whose+n(s)=the+n(s)+ofwhich/whom=of +which/whom+the+n(s)
eg:Thehouse whose roof was damaged has now been repaired.
=The house the roof of which was damaged has now been repaired.
=The house of which the roof was damaged has now been repaired.
九．oneof the +ns与the(only/very/right)one of the+ns结构作先行词的情况
⑴oneof the +ns结构，先行词应为thens，在定语从句中作主语时，从句谓语动词应用复数形式。
⑵the(only/very/right)one of the+ns，先行词应为the(only/very/right)one，在定语从句中作主语时，从句谓语动词应用单数形式。
eg:①Heis one of the students who fail the exam. ②He is the only one ofthe students who fails the exam.
十.“不定代词some/any/many/(a)few/most/分数/数词…+of/among+whom/which”结构或“of/among+whom/which+不定代词some/any/many/(a)few/most/分数/数词…”结构
以上两个结构可引导定语从句，其中of/among意为“……当中的”，表示具体(数量)范围。
eg:Ihave many apples,some of which are bad.(=I have many apples,of whichsome are bad.)
注：
一般情况下，当关系代词在(限制性)定语从句中作宾语时，可以省略。
非限制性定语从句一定不能用that、why引导，且引导词不可省略。
（3）"介词+that"一定不能引导定语从句。
（4）whose与名词放在一起才能引导定语从句。
（5）有些“动词+介词”的固定词组不可把介词置于关系代词前。这些常见的动词词组有：lookfor,look after,care for,send for,hear of/from/about,deal with等。
⑹有些时候，常用动词的习惯搭配来做定语从句的试题。如：offersb.sth.,buy sb.sth.,ask sb.sth.,turn to sb.for help等。
