Question

【题目】I think children ________ to make their own friends.

A. should allow B. shouldn’t allow C. be allowed D. should be allowed

Answer 1

【答案】D

【解析】句意：我认为孩子们应该被允许自己交朋友。A. should allow应该允许；B. shouldn’t allow不应该允许；C. be allowed被允许；D. should be allowed应该被允许。本句为宾语从句，主语与谓语之间存在被动关系，因此谓语为被动结构，但是C项be动词不能为原形。故选：D。
