She was so sad because she failed in the math test . Let’s her .

A. leave ; behind

B. leave ; alone

C. leave ; aside

D. leave ; out

答案：

A. leave ; behind

(答案→)B. leave ; alone

C. leave ; aside

D. leave ; out

解析：考查动词短语。Leave behind楼后；leave alone不理睬，不干涉，不打扰；leave aside不管，不顾，放在一边；leave out遗漏，省略；句意：她如此难受是因为他数学考试不及格，我们还是不打扰他吧！根据句意说明B正确。
