改错题 1、What is the cost going to come on at?2、He is becoming used to listen to others请帮忙告诉哪里错了,怎么修改还有一道，个人感觉没错。3、He walks as if he is drunk.

1, 去掉on
2, listen 改为 listening
3 is 改为 were

1,What is the cost going to come on at?----
What is the cost going to come out at?
成本算下来将会是多少 come out at的短语
2He is becoming used to listen to others----
he is used to listening to others
他已经习惯于倾听他人 be used to doing 习惯于做某事
3,He walks as if he is drunk.---He walks as if he were drunk.
as if 用上虚拟语气
