Answer 1

C

試題分析：因?yàn)榉衷~動(dòng)作“mention”與其邏輯主語(yǔ)“my mother”之間是主動(dòng)關(guān)系，故用現(xiàn)在分詞作時(shí)間狀語(yǔ)；又因?yàn)榉衷~的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)作之前，故用現(xiàn)在分詞的完成時(shí)。
點(diǎn)評(píng)：通過(guò)分詞與其邏輯主語(yǔ)之間的關(guān)系來(lái)判斷是使用過(guò)去分詞還是現(xiàn)在分詞；通過(guò)現(xiàn)在分詞與謂語(yǔ)動(dòng)詞發(fā)生的先后順序來(lái)判斷是使用現(xiàn)在分詞的一般式還是完成式。
