I AM HAPPY

Laurance- You look happy today!

Soony- I am happy. I just heard I passed my physics exam

Laurance- Congratulations! I'm glad somebody's happy.

Soony- Why? What's the matter?

Laurance- Oh, I'm just worried, I guess I have to take a history exam next week.

2）physics：物理学。
3）I'm glad somebody's happy:somebody重读，显示说话者本人心里有些忧虑。
4）What's the matter=What's troubling you
5）I'm worried:此句中worried是过去分词作表语，不是被动语态。
