It; whom【答案】 D【解析】考查主语从句和定语从句。句意：众所周知，这位年老的科学家，过去他的生活很艰难，在他八十多岁时仍然努力工作。It is known to us all that是个固定句型，意思是“众所周知”，这里it是形式主语，真正的主语是that引导的主
2、语从句，如果用as的话，as is known to us all后面要用逗号与后面的句子隔开，没有that；第二空中句子包含一个“介词+关系代词”引导的定语从句，指人，只能用whom，故选D。2. _ makes this shop different is that it offers more personal services.A. What B. Who C.

4、将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故A正确。4. _ Qidong won the title of National Civilized City made people in the city very excited.A. That B. What C. Which D. Whether【答案】 A【解析】考查主语从句。句意：得知启东市获
5、得了全国文明城市的称号，全城的人都很激动。_ Qidong won the title of National Civilized City是一个主语从句，引导词在从句中不作任何成分，也没有实际意义，所以用that，故选A。【点睛】在句中作主语的从句叫主语从句(Subjective Clause).主语从句是一种重要的名词性从句，在高考试题中频频出现。那么高考对它考查的重点是什么? I.由what等连词引导的从句在主语从句中, what = the thing(s) that,它本身在从句中充当某个成分,或是主语,或是宾语,其含义为所做/说/想的.II.由that引导的主语从句that在主语从

12、es DWhat is required【答案】 B【解析】句意：根据规定，你不应该告诉别人你电子邮件账户的密码。固定句式：It is required that-“据要求，根据规定”，it在句中作形式主语，真正的主语是后面that引导的主语从句。故选B。10.

19、elief的内容的，所以是同位语从句，从句不缺句子成分，因此用连接代词that。故选A。【点睛】同位语从句指的是在复合句中充当同位语的从句，属于名词性从句的范畴，同位语从句用来对其前面的抽象名词进行解释说明，被解释说明的词和同位语在逻辑上是主表关系。定语从句的先行词是名词或代词；而同位语从句的先行词只能是名词，而且仅限于idea，plan，fact，theory，promise，hope，news，doubt，truth，information，suggestion，question， thought，belief，conclusion等少数名词。引导词有that, whether, who,
20、 whom, what, whose, when, where, why, how等。此题很容易理解为定语从句，而导致选择错误。 that 既可引导同位语从句又可引导定语从句，其区别在于：1.同位语从句由连接词that引导，连接词that本身无意义，在同位语从句中不充当任何成分，不可省，不可以用其他词替代；2.定语从句由关系代词that引导，关系代词that在从句中充当一定的成分，作宾语时可省略.此句从句不缺成分，从句是解释belief 的内容，是同位语从句，所以用that。18.
