题目内容

【题目】A lot of trees________around here every year and we can enjoy fresher air now.

A.plantB.is plantedC.were plantedD.are planted

【答案】D

【解析】

句意：每年这附近都种植很多树，现在我们可以享受更新鲜的空气了。

考查一般现在时的被动语态。plant种植，动词原形；is planted一般现在时被动语态，主语为单数；were planted一般过去时被动语态；are planted一般现在时被动语态，主语为复数。根据句意和句中的every year可知，这句话应用一般现在时态，且主语A lot of trees与动词构成被动关系，主语是复数。故选D。
