2012 Olympic Games will take place in London.AIt BWhat CAs DWhich易错句型，难分难解【易错警示】易错点：as引导的非限制性定语从句，what引导的主语从句，it作形式主语和that引导的主语从句的混合考查。错误原因：不能正确地把握句子结构。解题思路：(注意划线部分的细微差别)What is known to us all是主语从句，所以选B；若选A，应该是：It is known to us all that the 2012 Olympic Games will take place in London.it是形式主语，that从句作真正的主语；若选C，应该是：“As is known to us all,the 2012 Olympic Games will take place in London.”as引导非限制性定语从句，指代后面的整个主句；此句还可以变成：“That the 2012 Olympic Games will take place in London is known to us all.”that引导主语从句。【易错警示】2Where did you get to know her?It was on the farm_we worked.Athat Bthere Cwhich Dwhere2Where did you get to know h【易错警示】易错点：强调句与it句式的混合考查。错误原因：把it开头的句子都误认为是强调句。解题思路：强调句的结构是：It is/was被强调部分that/who其它，它的判断方法是：如果去掉It is/was和that/who，剩下的仍然是一个完整的句子，是强调句，否则就要考虑这个it句式可能包含定语从句或状语从句。此题中where引导定语从句，在定语从句中作状语，先行词是farm。【易错警示】但奇怪的是，本句去掉It is/was 和要填的部分后仍然完整，所以很多同学选择A，误认为是强调句，实际上根据语境：你是在哪儿认识她的？我是在我们工作过的农场认识她的。所以本句是一个包含定语从句的省略的强调句。补全应该是：It was on the farm where we worked that I got to know her.所以选D。但奇怪的是，本句去掉It is/was 和要填的部分后仍然完知识拓展：强调句与含有状语从句的it句式的混合考查。(1)It was/will be时间段before从句，意思是“过才/就”注意：before引导的从句不能用将来时，只能用一般现在时或一般过去时。本句型的主句不能用一般现在时。在before前的时间暗示“多久”，译为“才”，在before前的时间暗示“短暂”，译为“就”。知识拓展：强调句与含有状语从句的it句式的混合考查。(2)It is/has been/was/had been时间段 since从句，意思是“自从”。注意：since从句若用一般过去时态，主句动词用is或has been，若since从句用过去完成时态，主句动词用was或had been。since从句的谓语动词一般是非延续性动词，如果从句的谓语动词是延续性动词，翻译成否定，因为时间的计算从since从句的动作完成或状态结束时算起。常见的延续性动词有：enjoy，smoke，live,teach等。如：It is three years since I smoked.It is three years since I stopped smoking.“我不吸烟有三年了。”如果要说：“我吸烟有三年了”，应该是：It is three years since I began to smoke.。(2)It is/has been/was/had been(3)It was时刻when从句意思是“当时候”。(4)含有not until的强调句：“It was not until.that其它”，或当强调句的被强调部分是时间时很容易和其它句型混淆。(3)It was时刻when从句意思是“当时候例：It was not until midnight_they reached the camp site.Athat Bwhen Cwhile Das解析句中含有not until的强调句。A例：It was not until midnight_Im sorry youve been waiting so long,but itll still be some time_Brian gets back.Abefore Bsince Ctill Dafter解析句中：It will be时间段before从句。句意：仍然要过一段时间Brian才能回来。AIm sorry youve been waitingDid Jack come back early last night?Yes.It was not yet eight oclock_he arrived home.Abefore Bwhen Cthat Duntil解析句中含有“It was时刻when从句”句型。句意：他到家时还不到八点。BDid Jack come back early lasThat was really a splendid evening.Its years_I enjoyed myself so much.Awhen BthatCbefore Dsince解析“It is/has been时间段since从句”句型。句意：我好多年没有这么高兴过了。DThat was really a splendid evIt was some time later_we realized the truth.Auntil Bbefore Cthat Dsince解析强调句，被强调部分是some time later。CIt was some time later_3Mom,what did your doctor say?He advised me to live_the air is fresher.Ain where Bin whichCthe place where Dwhere3Mom,what did your doctor s【易错警示】易错点：where引导的定语从句和where引导的状语从句和名词性从句的混合考查。错误原因：对定语从句的定势思维。解题思路：where引导的定语从句和where引导的状语从句和名词性从句的区别：where引导的定语从句有先行词，而状语从句和名词性从句没有先行词。【易错警示】联系：where状语从句引导词介词where名词性从句引导词介词先行词where定语从句引导词(介词先行词介词which定语从句引导词)本题考查的是where引导的状语从句，所以选D，不能换成B。如果要换成定语从句，全句为：He advised me to live in the place where the air is fresher.联系：where状语从句引导词4Mount Wuyi is such an attractive place of interest_everyone likes to visit.Athat BasCwhich Dwhat5His plan was such a good one _we all agreed to accept it.Aso Band Cthat Das4Mount Wuyi is such an attrac【易错警示】易错点：as引导的限制性定语从句与结果状语从句。错误原因：错误地认为such/so后面都是that。解题思路：在such.as/so.as中，as引导的是定语从句，先行词指物，as在定语从句中充当主语或宾语；在such.that./so.that.中，that引导的是状语从句，that只起连接作用，不作成分。【易错警示】第4题因为前面有such，所以锁定A、B。要填的部分在从句中作visit的宾语，所以选B，as引导定语从句；如果改成A，全句应为：Mount Wuyi is such an attractive place of interest that everyone likes to visit it.。第5题因为前面有such，所以锁定C、D，又因为要填的部分在从句中不作成分，所以选C，that引导状语从句；如果改成定语从句，全句应为：His plan was such a good one as we all agreed to accept.。第4题因为前面有such，所以锁定A、B。要填的部分在从6The road conditions there turned out to be very good，_was more than we could expect.Ait Bwhat Cwhich Dthat7The doctor advised Vera strongly that she should take a holiday,but_ didnt help.Ait Bshe Cwhich Dhe6The road conditions there tu【易错警示】易错点：非限制性定语从句与并列句的混合考查。错误原因：忽视关键词的作用。解题思路：识别并列句的关键：并列句通常用并列连词and，but，or等连接两个分句。如果无并列连词或标点是逗号，则可能是含有定语从句的主从复合句。【易错警示】第6题which引导的非限制性定语从句，指代前面的整个句子的内容，所以选C。如果改成并列句，全句为：The road conditions there turned out to be very good，And it/that was more than we could expect.。第7题but标志着两个分句是并列关系，it指代前面分句的内容，且充当第二个分句的主语，所以选A；若去掉but，应选C，which引导非限制性定语从句。第6题which引导的非限制性定语从句，指代前面的整个句
