题目内容
Water________ice．
- A.can be become
- B.can become
- C.can be becomed
- D.can became
分析：句意是“水能变成冰”，动词是become，而become是个连系动词，连系动词后面跟的是表语，不是宾语，所以become没有被动语态，要选B．can后面用动词原形。A和C项都是用了不存在的被动语态形式，也都错了(而且不存在becomed这个形式，become的过去分词是become)．
--Can you turn water ________ ice?
--Of course, I can. It's very easy. You can do it by cooling water.
