名词性从句的时态和语序问题 3 名词性从句的语气问题 4 同位语从句与定语从句的比较区别 1 名词性从句的引导词问题问题1 Greatchangeshavetakenplaceinthatschool Itisnolonger itwas20yearsago itwassopoorlyequipped 05安徽卷 A what whenB that whichC what whichD which that 前句考查的是that与what的区别 that在名词性从句中不充当任何成分 而what可充当名词性的成分 前句的表语从句中还缺少表语 故只能用what 后句是定语从句 修饰20yearsago 所以须用when 问题2 1 Whatthedoctorsreallydoubtis mymotherwillrecoverfromtheseriousdiseasesoon 上海2001 A whenB ifC whetherD why2 Elephantshavetheirownwaytotelltheshapeofanobjectand itisroughorsmooth 05天津卷 A 不填B whetherC howD what 在名词性从句中表示 是否 这一概念时 连词if一般只能引导宾语从句 而题1是表语从句 故不能选B 注意doubt的用法 如果是肯定句 用whether 如果是否定句 用that 宾语从句中 以下情况只用whether不用if 与or连用时 后接不定式短语时 在decide besure等动词后 问题3 leavestheroomlastoughttoturnoffthelights MET1988 A AnyoneB ThepersonC WhoeverD Who whoever引导名词性从句时表示 无论哪一个 相当于anyonewho who引导名词性从句时表示带有疑问的 谁 根据该题的意思不难作出选择 选项A B后都缺少了who 而引导定语从句的who是不能省略的 同时还需要注意whoever与nomatterwho whatever与nomatterwhat等的区别 wh ever既可引导名词性从句也可引导状语从句 而nomatterwh 只能引导状语从句 问题4 1 Iwassurprisedbyherwords whichmademerecognize sillymistakesIhadmade 05湖南卷 A whatB thatC howD which2 Parentsaretaughttounderstand importanteducationistotheirchildren sfuture 04广东 A thatB howC suchD so what与how引导感叹句时 what后加名词 how后加形容词和副词 其结构为 What a adj n 但要注意在what后不能加表示数量的many much few little等词 How adj a n 要注意的是how后的名词只能为单数名词 题1中是复数名词 只能用what 题2中的正常语序是 educationisimportanttotheir 所以选B 1 Scientiststhinkthatthecontinents alwayswherethey today 05北京卷 A aren t areB aren t wereC weren t areD weren t were2 Hurryup AliceandSuearewaitingforyouattheschoolgate Oh Ithoughtthey withoutme 05江西卷 A wentB aregoingC havegoneD hadgone 当主句的动词为现在和将来时态时 名词性从句中的动作根据所发生的时间来定 可以有各种时态 当主句的动词为过去时态时 从句中的动作一般都要使用相应的过去时 除非表示客观真理 2 名词性从句中的时态问题 1 Someoneisringingthedoorbell Goandsee 全国2000 A whoisheB whoheisC whoisitD whoitis2 Thephotographswillshowyou MET1989 A whatdoesourvillagelooklikeB whatourvillagelookslikeC howdoesourvillagelooklikeD howourvillagelookslike 名词性从句中都用陈述语序 不用倒装语序 题1中的干扰项是B 对想要知道的人提问或应答都用it而不用人称代词he I you等 题2只要注意是介词宾语就行了 3 名词性从句中的语序问题 4 名词性从句中的虚拟语气A 宾语从句中的虚拟语气在动词suggest order demand request desire insist require decide determine advise recommend deserve 值得提及 后需用should型的虚拟语气 Theteacherdemandedthatthework before4o clock A finishedB befinishedC shouldfinishD finish2 Whatdidthedoctorsayaboutyourmother sillness Hesuggestedthatshe anoperationatonce A musthaveB hadC haveD hadhad B 主语从句中的虚拟语气基本句型 Itissuggested ordered proposed required demanded requested insisted should doItisimportant necessary natural desirable strange advisable imperative that should doItisapity
