17、从句定语从句2 同位语从句和定语从句的区别：1） 同位语从句that 只起连接作用，不作任何成分 定语从句 that 是关系代词，起连接作用和充 当宾语和主语2） 同位语从句that 不能省 定语从句that 在从句中作宾语时，可以省I have heard the news that he visited our factory .I have heard the news that he told you yesterday .考点一：考查名词性从句的引导词 that 与 what 的区别考例（ 1 ）： _we cant get seems better than _we have.（N

18、MET1996）A. What； what B. What； that C. That； that D. That； what分析：在名词性从句中 that 与 What 的区别是： that 在从句中不充当句子成分，只起连接作用；而 what 不仅起连接作用，而且也可充当句子成分。此题考查了两个名词性从句：主语从句和宾语从句， what 在这两个名词性从句中都作宾语。考例 （2）： It worried her a bit _ her hair was turning grey.A. while B. if C. that D. for分析：句首的先行词 It 作形式主语，真正的主语是后面的

19、从句“ that her hair was turning grey”。 此句也可以改为： That her hair was turning grey worried her a bit. that 在主语从句中不充当句子成分，只起连接作用。考点二：考查名词性从句中的考点二：考查名词性从句中的 it 作形式主语作形式主语或形式宾语或形式宾语 考例 （1）： _is a fact that English is being accepted as an international language.（NMET1995）A. There B. This C. That D. It分析：在名词性从

20、句中为了保持句子的平衡，往往用先行词 it 作形式主语或形式宾语，而把真正的主语和宾语放到后面，尤其是 that 引导的主语从句往往用先行词 it 作形式主语。此句也可以改写为： That English is being accepted as an international language is a fact.考例（ 2 ） ： I hate _when people talk with their mouths full. （NMET1998） A. it B. that C. this D. them分析：此题考查用先行词 it 作形式宾语，而把真正的宾语从句放到后面。其他代词均不

21、能作形式主语或形式宾语。考点三：考查名词性从句的语序 考例： The photographs will show you _. （NET1989）A. what does our village look like B . what our village looks like C. how does our village look like D. how our village looks like分析：在名词性从句中，关联词要提到句首，句子用陈述句语序。当关联词含有疑问的意义时，考生受习惯影响往往会错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。本题中引导词 what

22、 作介词 like 的宾语，而副词 how 不能作介词 like 的宾语，所以排除 C 、 D ；而 A 项是疑问句语序，故只能选 B .考点四：考查名词性从句的引导词 whether 与 if 及 that 的区别 考例： _well go camping tomorrow depends on the weather .（NMET1996） A. If B. Whether C. That D. Where分析： whether 与 if （意为“是否”）的区别是：在引导宾语从句时两者可以互换，但引导介词后边的宾语从句或从句后面紧跟 or not 时只能用 whether， 而不能用 if

23、 .在引导主语从句、表语从句和同位语从句时，只能用 whether， 而不能用 if ，例如：1.Whether it is true remains a problem. 这件事是否真实还是个问题。2.What the doctors really doubt is whether my mother will recover from the serious disease soon. （上海 2001 ）医生真正怀疑的是我母亲能否很快从重病中恢复过来。 3.I am in doubt whether I should agree to the plan. 我不知道自己是否该同意这计划。注

24、：以上三句分别为主语从句、表语从句和同位语从句。只能用 whether 引导，不能用 if .考点五：从句中的“疑问词 +ever” 引导的从句与“ no matter+ 疑问词”引导的从句的区别考例（ 1 ） ：_leaves the room last ought to turn off the lights.（NET1988）A. Anyone B. The person C. Whoever D. Who分析： Whoever 引导的是主语从句，强调“无论谁”，它在主语从句中作主语，相当于 anyone who 或 the person who. 如果要选 A 或 B ，必须在它们后面

25、再加上引导定语从句的关系代词 who. 如果选 D 就体现不出“无论谁”的含义了。考例（ 2 ） ：Sarah hopes to become a friend of _shares her interests. （1995）A. anyone B. whomeverC. whoever D. no matter who分析：“疑问词 +ever ”引导的名词性从句与“ no matter+ 疑问词”引导的从句的区别是：前者既可以引导名词性从句也可以引导让步状语从句，后者只能引导让步状语从句。首先排除 A 和 D ，又因为从句中缺少的是主语，故排除 B .考点六：考查名词性从句中的虚拟语气 考

26、例： It is necessary that a college student _at least a foreign languageA. masters B. should master C. mastered D. will master分析： It 作形式主语， that 引导的主语从句中的谓语动词要用虚拟语气。 具体有以下几个方面具体有以下几个方面: 1 .在主语从句中用来表示惊奇、怀疑、惋惜、理应如此等，谓语动词要用虚拟语气“ （should）+do”。 常用的句型有： It is necessary （important， natural， strange， etc.） th

27、atIt is a pity （a shame， no wonder， etc.）that It is suggested （requested， proposed， desired， etc.）that 例如：It is strange that she （should）think so. 真奇怪，她竟然这么想。It is necessary that he （should）be sent there at once. 应该马上派他去那里。It is suggested that Mr. Wang give a performance at the party. 有人建议王先生在晚会上演个节

28、目。 2 .谓语动词是表示建议、请求、命令、要求、坚持等及物动词时，其后边的宾语从句要用虚拟语气。常用的这类动词有 suggest， propose， insist， desire， demand， request， order， command 等，谓语动词要用虚拟语气“ （should）+do” .例如：I insist that she （should）do her work alone. 我坚持要她自己完成工作。The commander ordered that troops （should）set off at once. 司令员命令部队马上出发。3 .主语是 suggestion

29、， proposal， request， idea 等表示建议、请求、命令、要求、决定等意义的名词时，表语从句和同位语从句中的谓语动词要用虚拟语气“ （should）+do ”。例如：My idea is that another meeting （should）be held to discuss the problem. 我建议再开一次会来讨论这个问题。They received orders that the work（should） be finished by the end of this month. 他们接到了本月底完成这项工作的命令.1. _made the school p
