20.After having checked all the windows and doors were closed and________ all the lights
were turned off,the teacher left the Classroom.(  )
A.whatB.thatC.howD.why

分析 检查完门窗都关好了,所有的灯也都关了后,老师离开了教室.

解答 答案:B 
题干中all the windows and doors were closed 和all the lights were turned off都充当动词check的宾语;宾语从句中的连词that通常可以省略,但为了避免歧义时,不可省略.故选B.

点评 本题考查了宾语从句中连词that的特殊用法.宾语从句中连词that通常可以省略,但如果引起歧义则不能省略.本题如果省略了that句意就有了两种解释:一种是all the windows and doors were closed 和all the lights were turned off都充当动词check的宾语;另一种是After having checked all the windows and doors were closed和all the lights were turned off并列,很明显句意就错误了.

Are Sweeteners (甜味剂) Safe and Healthy?
