问题补充：

A. cloud; will rain

B. cloudy; will rain

C. cloudy; is going to rain

D. cloud; is going to rain

答案：

A. cloud; will rain

B. cloudy; will rain

(答案→)C. cloudy; is going to rain

D. cloud; is going to rain

解析：句意：天很阴天，我认为明天会下雨。cloudy是形容词，阴天的；cloud是名词，云彩；第一空是作表语，所以应该用形容词；第二空根据时间状语tomorrow可知谓语动词应该用将来时。故选C。
