5．經(jīng)�？吹铰段鞯母赣H開車送她上學．
Lucy's fatheris often seen to drive her to school by car．

Answer 1

分析 經(jīng)�？吹铰段鞯母赣H開車送她上學．

解答 根據(jù)所給漢語提示，主語是Lucy's father，故句子用被動語態(tài)，由"經(jīng)常"可判斷用一般現(xiàn)在時，一般現(xiàn)在時的被動語態(tài)：am/is/are+過去分詞；see sb．do sth．看到某人做…的被動形式為sb．be seen to do sth．某人被看到做…，主動形式為省略to的不定式作賓補，被動形式須將省略的to加上，故填is often seen to drive her to school by car．

點評 使役動詞make/let sb do sth和感官動詞see（hear，watch，feel） sb do sth結構變成被動句，要把省略的to加上．
