问题补充：

Don’t cross the street when the traffic is red. You may

A. in danger

B. in dangerous

C. be in danger

D. be in dangerous

答案：

A. in danger

B. in dangerous

(答案→)C. be in danger

D. be in dangerous

解析：句意：当红灯亮时，不要横穿马路。你可能很危险。短语in danger，处于危险当中，in 是介词，后面接名词作宾语，dangerous是形容词，故选项BD结构错误。英语中情态动词不能独立构成谓语，故选C。
