Question

【题目】When a new problem _____ in the experiment, no one could do with it apart from Mary.

A.aroseB.was came up

C.roseD.came up with

Answer 1

【答案】A

【解析】

考查单词和词组辨析。句意：当实验中出现新问题时，除了玛丽没有人能处理。A. arose出现，引发；B. was came up被提出；C. rose上升；D. came up with提出，想出。动词短语come up“被提出”，was came up是错误的；此处指新问题“出现”。故选A。
