If we continue to destroy and waste the natural resources like this, we will it sooner or later.

A. run out

Brun out of

C. use up

D. lack of

答案：

A. run out

(答案→)B. run out of

C. use up

D. lack of

解析：考查短语辨析。run out 被用完，run out of 表示主动，用完什么，use up 用光，为不及物动词短语，lack of 缺少，句意：如果我们继续像这样毁坏或浪费自然资源的话，我们迟早会把它用完的。所以选B。
