11.(2014·煙臺(tái)高一檢測(cè)) Steve Jobs has gone but ______ he has left behind is truly extraordinary.
A.that B.why
C.what D.how
答案：C 分析句子結(jié)構(gòu)可知，“________he has left behind”是主語(yǔ)從句，且關(guān)系代詞在從句中作賓語(yǔ)，故選what。
12.(2014·天津，14)I think ________ impress me about his painting is the colours he uses.
A.what B.that
C.which D.who
答案：A 考查名詞性從句。句意：我認(rèn)為關(guān)于他的繪畫讓我印象深刻的是他使用的顏色。impresses缺少主語(yǔ)，故用what引導(dǎo)名詞性從句;that引導(dǎo)名詞性從句，不作成分。
13.(2014·泰安高一檢測(cè))__________ is known to all is ________ we won 38 gold medals in 2012 London Olympic Games.
A.It; that B.As; what
C.What; that D.That; what
答案：C 句意：眾所周知，2012年倫敦奧運(yùn)會(huì)上我們贏得了38枚金牌。________is known to all是主語(yǔ)從句，從句中缺少主語(yǔ)，意為“所……的”，應(yīng)由what引導(dǎo);第二個(gè)is后的部分是表語(yǔ)從句，且從句表陳述意義，應(yīng)由that引導(dǎo)，且不可省略。故選C。
14.________ seems to be no possibility ________ Li Hua can win the first prize in the 100meter race.
A.It; that B.There; that
C.There; whether D.It; whether
答案：B There seems to be是固定表達(dá);第二個(gè)空填that，引導(dǎo)同位語(yǔ)從句補(bǔ)充說(shuō)明possibility的具體內(nèi)容。故選B。
15.Why and how he came here ________ yet.
A.is not known B.are not known
C.has not known D.have not been known
答案：A 句意：他為什么及如何來(lái)這兒還不知道。Why and how引導(dǎo)的從句主語(yǔ)，謂語(yǔ)動(dòng)詞用單數(shù)，且不被知道，故選A。
