17.________ thoroughly,the garden looked more beautiful than ever before.( 。
A.CleaningB.Having been cleaned
C.Having it cleanedD.He had cleaned it

分析 徹底清掃后,這個(gè)花園看上去比以前更漂亮了.

解答 答案:B
該題考查非謂語(yǔ)動(dòng)詞作成分,本題首先排除D,因?yàn)樵谝粋(gè)句子中如果沒(méi)有并列連詞(并列句)和關(guān)系詞(復(fù)合句)連接是不允許存在兩套主謂結(jié)構(gòu)的,分析該句句子結(jié)構(gòu)可知____ thoroughly在句中作狀語(yǔ),又因主句主語(yǔ)the garden與clean存在邏輯上的動(dòng)賓關(guān)系,故應(yīng)使用過(guò)去分詞或現(xiàn)在分詞的被動(dòng)式作狀語(yǔ),所以排除A和C,由于非謂語(yǔ)動(dòng)作clean在謂語(yǔ)動(dòng)作look之前發(fā)生,所以應(yīng)使用現(xiàn)在分詞的完成式,故選B.

點(diǎn)評(píng) 考查非謂語(yǔ)作成分時(shí),一定要注意兩點(diǎn):1、非謂語(yǔ)動(dòng)詞在句中作什么成分;2、非謂語(yǔ)動(dòng)詞與邏輯主語(yǔ)存在的關(guān)系(主謂或動(dòng)賓)
