题目内容
2.Many trees _____ by us every year.( )| A. | plant | B. | plants | C. | are planted | D. | were planted |
分析 每年我们都栽很多树.
解答 答案:C.
首先根据时间状语every year,判断句中的谓语动词是经常性反复性的动作,所以用一般现在时,主语Many trees 是动作plant 的承受者,所以用被动语态,一般现在时被动语态的构成是:主语+am/is/are+动词的过去分词,主语是复数名词,be动词用are,故选C.
点评 本题考查时态和语态.每个时态都有标志词,熟记这些标志词是做题的关键.在没有时间状语的情况下可以根据语境来对时态做出判断.判断语态的关键则是观察主语是谓语动词的执行者还是承受者.
