1.The new technology,if ________ to agriculture,will be a great help to increase the grain output.( 。
A.applyingB.to applyC.appliedD.having applied

分析 這項(xiàng)新技術(shù),如果被應(yīng)用于農(nóng)業(yè),將對(duì)提高糧食產(chǎn)量有很大幫助.

解答 答案:C
此處用在if之后作條件狀語,相當(dāng)于if引導(dǎo)的條件狀語從句;由于動(dòng)詞apply與其邏輯主語the new technology構(gòu)成被動(dòng)關(guān)系,故該從句應(yīng)使用被動(dòng)語態(tài),即if the new technology is applied to agriculture;由于從句的主語與主句的主語一致,都是the new technology;并且從句的謂語動(dòng)詞中含有助動(dòng)詞be(is),因此此處可以省略主語the new technology 與助動(dòng)詞is,使用過去分詞形式;故選C.

點(diǎn)評(píng) 做本題時(shí),需要了解過去分詞作條件狀語,相當(dāng)于if引導(dǎo)的條件狀語從句的用法:如果狀語從句的主語與主句的主語一致,而且狀語從句的謂語中有助/系動(dòng)詞be,便可將狀語從句中的主語連同be一同省略,用"連詞+過去分詞"作狀語.
