We need to check our English and our listening. These checks help us do that. They help us show that we are listening. They help us show what we heard. They help us show what we understood.
“I don’t understand” is not helpful.
“This is wrong” is not helpful.
This is helpful:
You are introducing yourself. You told me your name, you said your name is Mahiro. You told me about your job. You said you “work company.”
Can you tell me the name of the company or the kind of work you do?
I’m listening to you. I know what you are talking about, your job. I don’t understand what your job is.
I didn’t tell you that you made a mistake, I told you I want to understand you.
We all need to know that we are being listened to. We all need to know that people want to understand us.
These checks help us do that, and they help us to do it in English.
