Learn English – Which one is correct in “How to …”? VS “How to …”

You liked the concert how? sounds very unnatural to a typical American. In most cases, the question would immediately identify the questioner as a non-native English speaker. How did you like the concert? is the correct and typical way to ask the question.

However, there is a case in which You liked the concert how? can be correct in conversational American English.

Person 1: How did you like the concert?

Person 2: I liked it. I plugged my ears and closed my eyes.

Person 1: You liked the concert how? (The vocal intonation heavily emphasizes how.)

Person 1 is essentially saying, I can't believe you enjoyed the concert like that. Can you confirm that you really meant what I heard? Person 2 has already provided some information. Person 1 is expressing disbelief or astonishment, and asking for clarification. You liked the concert how? is not the initial inquiry.

Here are some more examples:

The concert started when? (After hearing the concert started 3 hours late.)

The concert was held where? (After hearing the concert for a popular group was held in a too-small venue.)

These examples are exceptions, and are probably only used in informal, conversational English.

The correct phrasing is, "Where were you yesterday?"

"Have been" is continuous, so it doesn't make sense to use it with "yesterday", which is one specific time. You can say, "Where have you been the last few days?", but NOT "Where have you been yesterday?".

"Did be" is simply not used by native speakers. I don't know that it violates any general rule, but no one says that.
