population是定语从句的先行词，指“全体居民”。
2.—Where did you meet the famous actress?—It was in the supermarket ________we went shopping last Sunday.A.whichB.thatC.whereD.there解析where引导定语从句，修饰supermarket，where在从句中作地点状语，实际上答语为省略句，补全为：It was in the supermarket where we went shopping last Sunday thatI met the famous actress.。
3.________ is known，John studies in ________ is considered the best school in the city.A.Which；whichB.What；whatC.It；whichD.As；what解析句意为：众所周知，约翰在被认为是本市最好的学校上学。
第一空为as引导的非限制性定语从句，as代表整个主句的意思；第二空为宾语从句，且从句中缺少主语，故填what。
因此D项正确。
4.She may have been caught in the heavy traffic，______ she won’t arrive here by five o’clock.A.in caseB.in case ofC.in that caseD.in which case解析句意为：她可能陷入交通堵塞了，那样的话，她就不能5点到达了。
本题考查定语从句，故D项正确。
如果变为并列句，则C项正确。
5.Thousands of Haitians cheered as the Chinese medical team arrived，many of ________ even cried with joy.A.thoseB.themC.whomD.who解析本句既没有并列连词也没有从属连词，故可判断逗号后为非限制性定语从句，故排除A、B两项；本句先行词为thousands of Haitians，代入定语从句后为：...many of the thousands of Haitians even cried with joy.，由此可知，该先行词在定语从句中作介词of的宾语，且指人，故用whom引导，答案为C项。
备考策略1.注意知识积累，掌握基本句型。
高考备考时，应加强对从句语法特征和语意特征的思考和学习，形成纯正的英语思维能力。
注意相似句型的积累，比较其结构和意义。
在平时的阅读过程中，遇到从句的时候，要停下来，考虑分析其功能和意义。
2.分析句子成分，判断从句功能。
遇到考查句法的题目时，要通读全句，首先考虑是不是某种句型，如强调句型；题干句若是疑问句，首先把它恢复为正常语序；观察设空的前前后后，确定相关从句的性质，确定从句性质后，参考相关从句的用法特点，从而做出取舍；注意标点符号和并列连词的作用。
3.掌握从句要点，选择合适的连接词。
定语从句中的关系词要作成分，关系代词that，which，as通常作主语或宾语；whose作定语；关系副词where，when，why通常作状语。
做题时，首先要分析从句成分，选择合适的连接词。
考点与考题考点一“介词＋which/whom”中介词的确定1.与定语从句中的动词构成搭配。
The man (who/whom/that) I talked about at the meeting is from Beijing University. ＝The man about whom I talked at the meeting is from Beijing University.但像look for，look after等短语是不可拆开的，故不能将for，after等提前和关系代词连用一起引导定语从句。
2.与定语从句所修饰的先行词构成搭配。
He built a telescope，through which he could study the skies.3.“of which/whom”表示所属关系。
Recently I bought an ancient vase，the price of which (＝whose price/of which the price) was very reasonable.4.“复杂介词＋which/whom”引导定语从句。
They arrived at a farmhouse，in_front_of which sat an old man.5.通过句子的意思来判断。
She was educated at Beijing University，after which she went on to have her advanced study abroad.6.关系副词可以改为“介词＋which”，其中介词要根据和先行词之间的关系来确定。
He will always remember the day on which (＝on the day) his father returned fromAmerica.如句中是the year，则用in which (in the year)来引导定语从句。
考题印证1.English is a language shared by several diverse cultures，each of ________uses itsomewhat differently.(2011·浙江，8)A.whichB.whatC.themD.those解析考查“不定代词＋of＋which”引导的定语从句。
which指代的是cultures。
2.She showed the visitors around the museum，the construction ________had taken morethan threeyears. (2011·江西，34) A.for which B.with whichC.of whichD.to which解析考查“名词＋of＋which”引导的定语从句。
which指代的是the museum。
3.There are 51 students in Class Three，________ failed in the test.A.all of whichB.all of themC.none of whomD.none of them解析后半句是非限制性定语从句，修饰先行词students，应用whom引导；因为前后两句之间没有并列连词，所以B、D两项不对。
4.We found some precious jars and vases in an ancient tomb，________ you know，arevaluable.A.even the pieces of whichB.which even piecesC.even the pieces of themD.whose even the pieces解析句意为：我们在一座古墓中发现了一些珍贵的罐子和花瓶，你知道，甚至连碎片也很有价值。
先行词为jars and vases，从句表述的是“甚至它们的碎片也是很有价值的”，答案只能选A项。
C项应加连词and；D项应改为“even whose pieces”。
5.People living on this island depend on tourism，________ development there won’tbe much work.A.without itsB.without whoseC.by whichD.without which解析tourism是先行词，定语从句中development缺少定语，所以用whose引导。
由题意知，介词要用without，表示条件。
考点二as和which引导的非限制性定语从句的区别1.as引导的非限制性定语从句既可在主句前，也可在主句后，有时还可在主句中；which引导的从句只能放在主句后。
2.as和which在从句中作宾语时可互换，作系动词或be动词的主语时也可互换，但作实义动词的主语时一般只用which。
3.当主、从句在意义上前后自然连贯时，既可用as，也可用which；如果语义不一致或者从句具有转折含义时，则只能用which。
