  • 第1题：

     _____ a teacher in a university, it is necessary to have at least a master's degree.

    (A) To become (B) Become (C) One become (D) On becoming

     

     


    换个语序就可以了
    it is necessary to have at least a master's degree------a teacher in a university
    显然应该填to become
    这里的to become a teacher in a university 做主语，用becoming应该也可以，但题目中没有这个选项
    而CD中都有one，有sb的一般会有for出现，而题中没有，因此只能选A
