问一个英语问题“A is three times lager than B”翻译是“A比B大3倍还是4倍”错了，是A是B

Three times.
My English teacher Michelle had been asked such a question in the class ,and she said that Englishmen meant three times when saying this.
She also added that it was never good for you to think this question in a Chinese way,or you would make a joke.

3倍

A比B大三倍,即A是B的四倍.
