A: What a wonderful museum!

B: It's great, isn't it?

A: Let's go to the Animal Room on the second floor. I need some ____ for my science report.

B: Me, too. Let's go.

A: Hey, Gina! Come and see the money exhibition!

B: Be ____, please, Jack! You mustn't shout loudly in the museum.

A: Oh, I'm sorry. Look at the monkey's tail! I've got to get in here...

B: Stop! Don't ____ the rope!

A: Oh. Why not?

B: Can't you see the ____? "No entry (进入)."

A: Oh, right. That's no good! Well, I'll just take a ____ with my camera then...

B: You can't do that, either. It's ____ the rule in the museum.

A: There certainly are a lot of rules in the museum. No wonder there are ____ people in this place.

B: Oh, my dear!

A: What's the matter, Gina?

B: My mobile phone! It's ____! What am I going to do?

A: Don't worry. We'd better go to the lost and found office. If someone finds it, they will ____ it there.

B: That phone is new! I have to find it, or Mum will ____ me!

A: I'm sure it will be all right, Gina. Let's go and see.

B: Yes, let's go downstairs.
