题目内容
7.In the past ten years,a lot of trees _______ on the hills in my hometown.( )A. | planted | B. | were planted | ||
C. | have planted | D. | have been planted |
分析 在过去的十年里,我家乡的山上种植了许多树木.
解答 答案:D
根据句中的时间状语In the past ten years(在过去的十年里)可知,本句应使用现在完成时;由于本句的主语 a lot of trees 与谓语动词plant构成被动关系,因此此处应使用现在完成时态的被动语态(have/has+been+done);故选D
点评 做本题时,首先应根据句中的时间状语来判断要使用的时态;其次通过正确分析主语与谓语动词的关系来确定应使用的语态;由于本题考查的是现在完成时态的被动语态,因此应熟练掌握现在完成时态的意义及用法.
