We to speak aloud in the public place.

A. shouldn’t be allowed

B. should allow

C. should be allowed

D. shouldn’t allow

答案：

(答案→)A. shouldn’t be allowed

B. should allow

C. should be allowed

D. shouldn’t allow

解析：句意：我们不允许在公共场所大声讲话。主语we和动词allow是被动关系，用被动语态be allowed, 前面加情态动词shouldn’t,系动词be用原形，shouldn’t be allowed,故选A。
