问题：问2道英语非谓语地选择题1.Hiswordsleftme_?_w 
1.His words left me _?_ what he was driving at.A.to wonder  B.wondering  .wondered  D.wonder2.I 'm .afraid your suggestion can't help _?_ the service of their shop.A.improving  B.in improving  C.improve  D.for improving为什么选B和C？
回答：1.leave+宾语+宾补(doing/adj./pp)让宾语处于某种状态因为sb和wonder之间是主动关系,所以用动词的-ingWeallwentaway, n'thelptodosth=can'thelpdosth帮助做某事这里是省略了to,意思是我恐怕你的建议不能帮助提高这家商店的服务。can'thelpdoingsth情不自禁的作某事can'thelpbutdosth不得不作某事
