Quirrell: Troll in the dungeon! Troll in the dungeon! Thought you ought to know.

Others: Ah!

Dumbledore: SILENCE! Everyone will please not panic! Now prefects will lead their house back to the dormitories. Teachers will follow me to the dungeons.

Percy: Gryffindors, keep up, please, and stay alert!

Harry: How could a troll get in?

Ron: Not on its own. Trolls are really stupid. Probably people playing jokes. What?

Harry: Hermione! She doesn't know!

Ron: I think the troll's left the dungeon!

Harry: It's going into the girl's bathroom. Hermione move!

Hermione: Help! Help!

Ron: Hey, pea-brain!

Hermione: Ah! Help!

Harry: Woah!

Ron: Ugh!

Harry: Do something!

Ron: What?

Harry: Anything! Hurry up!

Hermione: Swish & Flick!

Ron: Wingardium Leviosa! Cool.

Hermione: Is it dead?

Harry: I don't think so. Just knocked out. Ugh.

Ron: Troll boogies.

McGonagall: Oh my goodness! Explain yourselves, both of you!

Harry & Ron: Well what it is-

Hermione: It's my fault Professor McGonagall.

McGonagall: Miss. Granger?

Hermione: I went looking for the troll I've read about them and I thought I could handle it. But I was wrong. If Harry and Ron hadn't come and found me? I'd probably be dead.

McGonagall: Be that as it may, it was an extremely foolish thing to do. I would have expected more rational behavior on your part and am very disappointed in you Miss. Granger. Five points will be taken from Gryffindor for your serious lack of judgment. As for you two gentlemen I just hope you realize how fortunate you are. Not many first year students could take on a fully grown mountain troll and live to tell the tale. Five points will be awarded to each of you, for sheer dumb luck.

妙语佳句，活学活用

1. Keep up

这个片语大家应该都不陌生，我们这里来重温一下。Keep up 的意思是"跟上，赶上"，当要表示"跟上，赶上……"时，用with 连接后面的事物。 例如：We try to keep up with the times.

2. Play jokes

"开玩笑"怎么说？就是这个play jokes。那要表示"对某人开玩笑"要怎么说呢？就是 play a joke on someone，例如：Richard called and said I had won ten thousand dollars, and it took me a second to realize he was playing a joke on me.

3. Knock out

"被打/弄晕"的意思，例如： It was just a swinging door, but it knocked her out. 这个片语也写作knock out cold.

4. Be that as it may

意为"Nevertheless, it may be true but 然而，不过"，例如：Be that as it may, I can't take your place on Monday.

5. Take on

这里的意思是"对抗，打败"，例如：This young wrestler was willing to take on all comers.
