A: Hi, Mike. Let's go to school. Oh, what's 1.             with your right arm?

B: I had bad 2.             yesterday evening. A small boy ran out while I was riding on my bike. I tried not

    to knock him, but I fell and hurt 3.              .

A: What a pity! Is it serious?

B: Not very. But I can't write now. The 4.             asked me to stay at home for a few days. Could you

    get my sick-leave note to Miss Li?

A: Sure. I hope you'll be all 5.             soon.

B: Thanks, Linda. Here is the note.
