例題4(1997年8月考題) unlike fossil fuels, which can be used only once, wind and solar power _____of energy.
(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(méi)有主語(yǔ),即沒(méi)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) today _____ of the earth live on a very small percentage of the earth's land surface.
(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??崭駜?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。
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。
例題7(1997年8月考題) because it was so closely related to communication, _____ art form to develop.
(a) drawing was probably the earliest
(b) to draw early was probably
(c) early drawing probably
(d) the earliest draw.
首先,我們分析句子結(jié)構(gòu)??崭袂笆莃ecause引導(dǎo)的原因狀語(yǔ)從句,也就是說(shuō),_____art form to develop應(yīng)該是完整的主謂結(jié)構(gòu)。而單數(shù)的art暗示它應(yīng)該是修飾名詞form,不定式to develop做補(bǔ)語(yǔ)。所以,空格內(nèi)應(yīng)填入完整的主謂結(jié)構(gòu)。
這時(shí),我們可以排除選項(xiàng)c和d,剩下選項(xiàng)a和b。仔細(xì)對(duì)比選項(xiàng)a和b,我們發(fā)現(xiàn)選項(xiàng)a更符合句意,因?yàn)閐rawing這個(gè)名詞(畫(huà))才可能是一種藝術(shù)形式(art form),而動(dòng)作to draw不可能是一種藝術(shù)形式。所以,正確答案是a。來(lái)源:www.examda.com
