题目内容
17.At the beginning of class,the noise of desk __________ could be heard outside the classroom.( )A. | opened and closed | B. | to be opened and closed | ||
C. | being opened and closed | D. | to open and close |
分析 在上课前,桌子被打开又关上的声音在教室外都听到了.
解答 答案:C
分析句意可知,open此处为动词,意思是开;close为动词,意思是关上,和desk之间都是被动关系,故使用be opened and closed,但在句子里做后置定语修饰desk,所以该成being opened and closed,故答案为C.
点评 考试须根据词性来确定所填词在句子里的作用.
