　　解題要點(diǎn)：同位語結(jié)構(gòu)是中國(guó)學(xué)生不甚熟悉而TOEFL考題中常出現(xiàn)的結(jié)構(gòu)。見到主語和謂語動(dòng)詞/系動(dòng)詞之間的，兩邊用逗號(hào)隔開的形式，應(yīng)首先考慮同位語的可能性，選擇名詞性結(jié)構(gòu)。

　　6. The worldwide race to develop an affordable synthetic fuel has so far consumed billions of dollars and __________ few results.

　　(A) yielded

　　(B) yielding

　　(C) yield ha

　　(D) has a yield of

　　考點(diǎn)：並列結(jié)構(gòu)。

　　分析：and前後兩部分，應(yīng)同形式、同性質(zhì)。此處and連接兩個(gè)謂語部分，前面是consumed…，後面應(yīng)也是一過去式的動(dòng)詞，即(A)yielded。

　　答案：A

　　考點(diǎn)：分詞短語作後置定語。

　　分析：此句是TOEFL�？季涫健７衷~短語作定語放在它所修飾的名詞後面(A)，相當(dāng)於被動(dòng)式的定語從句省掉關(guān)係代詞which/that及系動(dòng)詞be。(B)若改為which was chartered，(C)用which代替it，(D)去掉to be，亦可。

　　9. Thanks to modern irrigation, crops now grow abundantly in areas where once __________ cacti and sagebrush could live.

　　(B) is known as human knowledge

　　(C) known human knowledge

　　(D) is human knowledge known

　　答案：B

　　考點(diǎn)：what引導(dǎo)的名詞從句。

　　分析：介詞of應(yīng)後接名詞性成份作介詞賓語。What…結(jié)構(gòu)的作用相當(dāng)於一個(gè)名詞，它要麼是what+不定式，要麼是what從句，即名詞性從句。答案中無不定式形式，只有(B)能與what組成完整的從句，故選 (B)。(A)it與what重複。

　　12. Because of the Aleuts’ constant exposure to cold weather, they have long recognized __________ .

　　答案：D

　　考點(diǎn)：賓語。

　　分析：recognize是及物動(dòng)詞，其後應(yīng)接名詞性的成份作賓語。(D)是名詞片語，故選(D)。(B)看似省掉that的賓語從句，但fat前的定冠詞the是錯(cuò)誤的。(C)如改為how much fat則在句子結(jié)構(gòu)上亦是正確的。
