问题描述:

By helpful kindness the teacher _____the boy's nervousness.A.was broken down B.broke down
应该选哪一个,个人觉得应该选A,

亲,答案为:B.broke down
By helpful kindness the teacher (broke down) the new boy's shyness.老师和蔼可亲的态度减轻了这个新来孩子的紧张.来自《简明英汉词典》
假如选择A的话,意思正好相反,更重要的是,如果选择A,就是被动语态,就必须要加by了.
但是这里没有表示被动的by,所以不能选择A.
明白了吗?
