4.______ from this point,the problem presents no easy solution.(  )
A.SeeB.To seeC.SeenD.Seeing

分析 從這一點(diǎn)來(lái)看,這個(gè)問(wèn)題沒(méi)有簡(jiǎn)單的解決方案.

解答 答案C.
分析句子結(jié)構(gòu)可知,逗號(hào)之后是主句,兩個(gè)分句間沒(méi)有連接詞,所以逗號(hào)之前是非謂語(yǔ)動(dòng)詞形式,主句的主語(yǔ)是"the problem"與所給動(dòng)詞"see"存在邏輯上的被動(dòng)關(guān)系,因此用過(guò)去分詞,A項(xiàng)為動(dòng)詞原形,不符合語(yǔ)境,排除;B項(xiàng)不定式表動(dòng)作未發(fā)生,D項(xiàng)現(xiàn)在分詞表主動(dòng),都不符合,故排除,故選C.

點(diǎn)評(píng) 本題考查非謂語(yǔ)動(dòng)詞用法.做這類題目首先根據(jù)句意判斷是謂語(yǔ)還是非謂語(yǔ),如果是分詞做狀語(yǔ)的時(shí)候,看動(dòng)詞與邏輯主語(yǔ)構(gòu)成主動(dòng)關(guān)系,就使用現(xiàn)在分詞的形式;如果二者構(gòu)成被動(dòng)關(guān)系就使用過(guò)去分詞的形式.不定式表示動(dòng)作未發(fā)生作目的狀語(yǔ).
