Hints：
David
Professor Johnson
I was so angry yesterday! My biology teacher did not even let me explain why I missed the field trip. He just wouldn't let me pass!
That doesn't seem fair. I'd feel that way too if I were you.
I really can't stand the way David controls the conversation all the time. If he is going to be at your Christmas party, I just won't come.
I'm sorry you feel that way, but my mother insists that he come.
You're taking a course with Professor Johnson. What's your impression so far?
Well, many students could hardly stay awake in his class without first drinking a cup of coffee.
Have you ever put a computer together before?
No, never. But I think if we follow these instructions exactly, we won't have much trouble.
