20202021年 名詞性從句 章末測試經(jīng)典1一、名詞性從句1._________ is known to all is that the earth is smaller than the sun. A.AsB.WhatC.ItD.Which【答案】 B 【解析】【分析】句意:眾所周知,地球比太陽還小。復(fù)合句的主語是一個(gè)名詞性從句,從句沒有引導(dǎo)詞和主語,表示“所……的(事)”,故用what引導(dǎo),其雙重作用,故選B。 【點(diǎn)評】考查名詞性從句,本題涉及what引導(dǎo)的主語從句。2.Some people believe _______ has happened before or is happening now will repeat itself in the future. A.whateverB.wheneverC.whereverD.no matter what【答案】 A 【解析】【分析】句意:一些人認(rèn)為之前發(fā)生的或現(xiàn)在正在發(fā)生的任何事情在將來都會(huì)重復(fù)發(fā)生。Whatever has happened before or is happening now是一個(gè)主語從句,whatever既引導(dǎo)起這個(gè)主語從句,也在句中做主語。BC項(xiàng)都屬于副詞的性質(zhì),都不能做主語,通常只能做狀語;no matter what只能用來引導(dǎo)狀語從句,故選A。 【點(diǎn)評】考查名詞性從句,本題涉及特殊疑問詞+ever引導(dǎo)的主語從句。3.is even more important is the earth cooled down, water began to appear on its surface.A.When。 that。 whenB.What。 whether。 asC.What。 that。 asD.lt。 whether。 as【答案】 C 【解析】【分析】這題考查從句的用法,第一空填what引導(dǎo)主語從句,在主語從句中what做主語,第二空填that引導(dǎo)表語從句,在表語從句中,as是引導(dǎo)時(shí)間狀語從句,句意是:甚至更重要的是:隨著地球的冷卻,水開始出現(xiàn)在表面。選C。4.It________that the road will be closed tomorrow for repairs. A.was announcedB.has been announcedC.had been announcedD.would be announced【答案】 B 【解析】【分析】本題考查動(dòng)詞的時(shí)態(tài)和語態(tài)。題干句子中that到句子結(jié)束是賓語從句,且從句動(dòng)詞用“will+動(dòng)詞原形”表示將來,由此推斷出空白處謂語動(dòng)詞應(yīng)用現(xiàn)在的某種時(shí)態(tài),在所給四個(gè)選項(xiàng)中,只有B項(xiàng)正確。 【點(diǎn)評】考查現(xiàn)在完成時(shí)的被動(dòng)語態(tài),其結(jié)構(gòu)是have/has +been +done。需要注意賓語從句的時(shí)態(tài)。主句用現(xiàn)在時(shí),從句所需的任何時(shí)態(tài)。5.Located between the 16th and the 18th floor, ______ I call my “home” is more like a “bird39。s nest”.A.whichB.thatC.whatD.where【答案】 C 【解析】【分析】考查主語從句。What引導(dǎo)主語從句______ I call my “home”且 What在從句中充當(dāng)call的賓語。故選C。6.____ made me more unhappy was ___ the boy asked my friend to be his girlfriend and she agreed.
