Questions for native speakers
I am university student, and take a seminar in a third grade. In the class, we were given assignments, which is we check on how native speakers feel or think about the following questions. So I would like to ask your opinions. Could you answer the following questions?
1. “The plane must land in a few minute.” When you read this sentence, what kind of situation do you imagine? I’d like to know the meaning of “must” in this sentence. So what kind of meaning does the “must” include?
2. In the same way, how about “He can seem so sane.”?
3. What is the difference among Look, See and Watch?
4. “He could hear the phone ringing on the other end but no one answered.” In this sentence, do you think the phone rang straight? Does “can/could + feeling verb” mean an instant or a moment situation.
Thank you very much for your time, and I’m looking forward to your opinions.
