题目内容
19.In order to make our hometown more beautiful,lots of trees______last year.( )| A. | are planned | B. | have planted | C. | were planted | D. | planted |
分析 为了使我们的家乡更加漂亮,去年栽了许多树.
解答 答案:C.
首先根据时间状语last year,判断句子中的谓语动词用一般过去时,主语lots of trees是动作plant的承受者,表示"树被栽",所以用被动语态,一般过去时被动语态的构成是:主语+was/were+动词的过去分词,主语是复数名词,be动词用were,plant的过去分词是planted,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.
