Question

【题目】— Food problem is becoming a big one in China!

—I think the food ________ before going to shops or supermarkets.

A. is checked B. is checking

C. should be checked D. should check

Answer 1

【答案】C

【解析】

试题分析：句意：食品问题正在成为中国的一个大问题！我觉得在去商店或超市之前应该检查一下食物。food是check这一动作的承受者，该用被动语态， 结合句意，此处应用带情态动词的被动语态，所以选C。
