(A) for renewable sources
(B) the sources are renewable
(C) are renewable sources
(D) renewable sources
這里,句子的主干應(yīng)該是wind and solar power____ of energy.Unlike fossil fuels表示比較,做狀語(yǔ)。而which引導(dǎo)的從句which can be used only once修飾fossil fuels.我們將4個(gè)選項(xiàng)分別代入句子主干的空格中,得(A) wind and solar power for renewable sources of energy選項(xiàng)A沒有主語(yǔ),即沒有完整的主謂結(jié)構(gòu)。(B) wind and solar power the sources are renewable of energy很明顯,這也不能構(gòu)成一個(gè)完整的有意義的句子。(C) wind and solar power are renewable sources of energy這個(gè)選項(xiàng)最合適,因?yàn)橹髦^齊全,而且以名詞sources結(jié)尾,讓介詞短語(yǔ)of energy修飾。(D) wind and solar power renewable sources of energy很明顯,這也不能構(gòu)成一個(gè)完整的主謂結(jié)構(gòu)。所以,正確答案是C
例題5(1997年8月考題)

(A) about two-thirds populated
(B) the population is about two-thirds
(C) about two-thirds of the population
(D) of about two-thirds the population is
首先,分析句子結(jié)構(gòu)。根據(jù)句子的大意,動(dòng)詞live應(yīng)該是主句的謂語(yǔ)動(dòng)詞??崭裉钊氲膽?yīng)該是句子的主語(yǔ),而a very small percentage of修飾限定the Earth's land surface.我們簡(jiǎn)化這個(gè)句子,得出句子主干_____ live on the Earth's land surface.空格內(nèi)應(yīng)該填入名詞或者名詞短語(yǔ)。4個(gè)選項(xiàng)中,只有C是明顯的名詞短語(yǔ),代入后也符合句意。選項(xiàng)A中的populated不論是做定語(yǔ)還是謂語(yǔ)都不符合句意。而選項(xiàng)B和D都是帶有助動(dòng)詞的主謂結(jié)構(gòu),當(dāng)然不能填入只缺主語(yǔ)的句子中。所以,正確答案是C.
例題6(1997年8月考題)
Following the guidelines for speaking and voting established by the book Robert's Rules of Order, _____during meetings.
(A) and avoid large decision-making organizations' procedural confusion
(B) large decision-making organizations avoid procedural confusion
(C) is procedural confusion avoided by large decision-making organizations
(D) are avoiding procedural confusion in large decision-making organizations
首先,我們分析following以后空格以前句子的成分。其中的established by the book Robert's Rules of Order和for speaking and voting都修飾the guideline.所以,我們可以將空格前的成分簡(jiǎn)化為following the guidelines.那么這時(shí),原句成為Following the guidelines, _____ during meeting.和例題3一樣,following the guidelines不是做定語(yǔ)(伴隨狀語(yǔ))就是做謂語(yǔ)。如果它做定語(yǔ),后面必須帶自然語(yǔ)序的主謂結(jié)構(gòu);如果它做謂語(yǔ),后面必須帶倒裝的主謂結(jié)構(gòu)。由此,我們排除帶有and的選項(xiàng)A.根據(jù)句意(guidelines和confusion的意思)我們又可以排除選項(xiàng)C.這時(shí),我們只剩下選項(xiàng)B和D.選項(xiàng)D是主謂倒裝的結(jié)構(gòu),填入后主語(yǔ)應(yīng)該是avoiding procedural confusion,謂語(yǔ)動(dòng)詞是are.很明顯,avoiding procedural confusion后應(yīng)跟單數(shù)謂語(yǔ)動(dòng)詞。所以D也錯(cuò),只有B才可能是正確答案。代入句中,符合句意?,?BR> 例題7(1997年8月考題)

(A) drawing was probably the earliest
