Ben: Are you going to use your bike this afternoon, Shen Zhan?

Shen Zhan: No, I’m reading this book. It’s called the Book of Lists. It tells you all about the biggest and smallest things in the world. It’s very interesting.

Ben:Can I borrow your bike, please?

Shen Zhan: Well ….. try and answer five questions and you can borrow my bike. One right answer equals 15 minutes on my bike.

Ben: OK. That’ll be easy!

Shen Zhan: What is the highest mountian in the world?

Ben: Easy! Mount Qomolangma.

Shen Zhan: Which country is the biggest----Russia, Canada or China?

Ben: Your questions are getting easier and easier. It’s China, of course!

Shen Zhan: Which river is longer--- the Amazon or the Changjiang River?

Ben: Oh, that’s more difficult. Er….. I’m not sure. Maybe the Changjiang River?

Shen Zhan: Which lake in China is bigger----Boyang Lake or Qinghai Lake?

Ben: Now they’re getting more and more difficult. I don’t know. Boyang Lake?

Shen Zhan: Last question. Which ocean is the deepest in the world?

Ben: everyone knows that--- the Pacific. Well? Can I borrow your bike now?

Shen Zhan: Yes, you can!
