35、物时，用what, whatever（作主语、宾语） ；which, whichever（作主语、宾语） 。2. 句意完整缺连接副词： 指时间时，用 when；指地点时，用 where, wherever；指原因时，用 why；指方式时，用 how。3. 句意完整缺不作成分的连词:有含义的用 if, whether（是否） ；无含义的用 that。表五：考点梳理【考点二】考查名词性从句的在名词性从句中，除了关联词在从句句首外，其他部分应用陈述语序。而考生们往往使用疑问语序，特别是在以 wh引导的名词性从句中。克服这个问题的关键是要找准从句的主语。在试题的设置上会通过宾语从句、表语从句的语序来考

36、查，尤其是一些与特殊疑问句有关的宾语从句或表语从句。名词性从句思维导图10 / 14语序问题 These shoes look very good. I wonder _.A. how much cost they are B. how much do they cost C. how much they cost D. how much are they cost解析：选 C。根据题干中的及物动词 wonder 可知,how much 引导宾语从句，而名词性从句要用陈述语序，故排除疑问语序的 B、D 两项;A项可以改为 how much they cost 或 how much they a

37、re worth。故选 C 项。【考点三】考查宾语从句中的否定转移否定转移主要针对宾语从句。在宾语从句中，当谓语动词是 think/believe/suppose/imagine/guess/expect/consider 等表示 “认为、相信、猜测” 意义的词，并且主语是第一人称，时态是一般现在时，形式上是否定主句谓语动词的否定词，实际上否定的是宾语从句。在反意疑问句中，其中的附加问句要与从句保持一致，而且要把否定词转移到从句中去。I dont believe he treated the child like that, did he?Im sure youd rather she wen

38、t to school by bus, _?A. hadnt you B. wouldnt you C. arent I D. didnt she解析：选 B。题干中的 be sure 同 believe, 而且句子的主语是第一人称，时态是一般现在时，所以附加问句（反意疑问句）与从句保持一致。【考点四】考查形式主语、形式宾语当主语从句较长，而谓语较短时，为了避免“头重脚轻”，常常将从句后置，而用 it 作形式主语，置于句首。动词后接复合宾语，也可用 it作形式宾语。不能用 this 或 that 来代替 it。It is a pity that he cant attend the party

39、.We consider it necessary that he should improve his grammar.(that 不可以省略)_ is a fact that English is being accepted as an international language. A. There B. This C. That D. It解析：选 D。分析题干可知， it 作形式主语，代替真正的主语 that 从句。表五：考点梳理【考点五】考查名词性从句中虚拟语气的运用(1)主语从句、宾语从句、同位语从句和表语从句都会涉及到虚拟语气，一些表示建议、要求、命令的动词，如 insist

40、（坚持）/suggest （建议）/order（命令）/request （要求、请求）/require（要求）/recommend(建议)/urge(催促,力劝)等后的宾语从句中的谓语动词要用虚拟语气，即“should+do（动词原形） ”，其中的 should 可以省略。对应的名词作主语跟表语从句，或对应的名词跟同位语从句，也要用虚拟语气。但是如果有其他意义则例外，如 suggest 表示“暗示”时,所跟的宾语从句就用陈述语气。The teacher suggested that we (should) have a rest.It is suggested that he should a

41、dapt himself to new conditions.My suggestion that he should adapt himself to new conditions hasnt been accepted.My suggestion is that we (should) read English newspapers to improve our English.(2)主语从句中的某些句型，如 Its necessary/essential/strange/apity/a shame/no wonder；Its (high) time that .等句型中也常用虚拟语气，构成形式也是“should+动词原形” 。
