Question

【题目】Every year lots of trees along the streets to make our city more beautiful.

A. plant B. will plant

C. are planted D. have planted

Answer 1

【答案】C

【解析】句意：为了使我们的城市更加美丽，每年沿着街道很多树被种植。plant种植，动词原形；will plant一般将来时态；are planted一般现在时态的被动语态；have planted现在完成时，主动形式。这句话的主语lots of trees和谓语动词plant构成被动关系，这里应使用被动语态，故排除A、B和D三个选项，选C。
