问题描述:

"How do you do"is a very ___ question which you don't have to answer.
[A} usual [B] unusual
And please tell me the reason after answering me.
I think I should choose A,but the answer is B and I don't know why.

B] unusual
I think should choose B

Generally,a question should be answered. But here the question"How do you do?" is not a common question. It is used to greet others. It is uncommon.The question has a fixed answer,"How do you do?"
so here you should choose B, it is an unusual question you do have to answer(The Chinese meaning of the sentence is:它是一个没有必要回答的特殊的一个问句。)

B一般问题都要答案,它却you don't have to answer,所以unusual

A
How do you do 是一个你不用必须回答的常见的一个问题
常见

B,different from the usual ones.

A
确实是一句平常的话

A.你过的怎样是个很普遍的问句

B
看后半句:you don't have to answer
既然后半句否定,就意味着“有理由不去做某事”
按照常理,不应该不去回答一个常见的问题,所以选B
还有,英语题目有的比较冷门而且较难解释,这时应该联系语境.打破思维定势,大熟词在一些比较怪的题目中通常不会选.

A,这是一句常见的问候
