Conversation 1

Emma: Hi, Yaming What are you doing?

Yaming: Hi, Emma. I’m starting a test on animals and plants.

Emma: Sounds fun. Let’s take it together.

Yaming: OK. First question. What’s the largest animal in the world?

Emma: It’s the blue whale, right?

Yaming: Right. It’s also the heaviest animal on earth. Next question. Which animal runs the fastest?

Emma: Oh wait! I just read about it. The cheetah runs the fastest.

Yaming: Right again! And I think it’s the most beautiful animal in the world.

Emma: I completely agree with you.

Yaming: Now let’s answer the questions about plants. What is the oldest plant in the world?

Emma: Hmm, I’m not sure. Do you have any idea?

Yaming: Well, I think moss is one of the oldest plants. It appeared on earth around 470 million years ago ... Oh, look here. I’m correct!

Emma: Interesting! Let’s go on!

Yaming: Which kind of tree is the tallest in the world?

Emma: The redwood tree, right?

Yaming: Yes! I hope I can see some one day.
