英语选择题，呼救！Didyouleavethedoorsandw
Did you leave the doors and firmly _________?You kown there are many burglars these days. A、To fasten B、To be fastened C、fastened 答案是C，为什么不是B？
选C.呵呵! 变成陈述句 :leave the doors and windows firmly fastened..... 为leave+宾语+宾补 的结构,the doors and windows是宾语,fastened 是宾补,说明宾语的状态,与宾补是被动的关系,所以要用过去分词:) 希望对你有帮助!
