1. M: Judy, did you choose a topic for your science project?↵
W: Not yet. How about you, Ryan?↵
M: I'm curious about weather change. So I'm thinking about doing the project on that.↵
W: That's an interesting topic!↵
2. W: Look at this picture of a huge flower.↵
M: Wow, it is bigger than a person.↵
W: Yeah. I'm really curious about this flower. It also ⑤says here that the flower smells very bad, but insects love the smell.↵
M: Hmm, I wonder why.↵
3. W: Do you think we can be friends with lions, Todd?↵
M: No, Clare. I don't think so.↵
W: Well, I watched a video clip about friendship between two men and a lion.↵
M: Really? I'm curious about the story. Can you tell me more?↵
W: The two men raised a baby lion and sent her back into the wild. When the men and the lion met a year later, she remembered them.↵
M: Wow, that's so touching.↵
4. M: Look at this picture, Mina. We got a new puppy yesterday. He's only two weeks old.↵
W: Oh, Dylan, he's so small!↵
M: Yeah. He's as small as my hand now, but he'll ②get much bigger in a few months.↵
W: Wow, puppies grow very quickly.↵
5. W: George, that red house over there is my grandparents' house.↵
M: Wow, the tree by the house is really big.↵
W: Actually, that tree is as old as me, thirteen years old.↵
M: How do you know that, Kelly?↵
W: My grandfather planted the tree in 2004 when I was born.↵
6. M: Hi, I'm Toby. I'm going to give a presentation about the blue whale. It's the biggest sea animal in the world. How big is it? Well, it's about 30 m long. That means it's longer than a basketball court. Another interesting thing is that its tongue is as heavy as an elephant! Surprising, isn't it?↵
7. W: Hello, Dr. Watson. Can you tell us about your study?↵
M: I study animals that lived millions of years ago.↵
W: Oh, I'm curious about those animals. Were there any interesting ones?↵
M: Yes, there were many. This is the giant kangaroo. It lived in Australia. It was as heavy as three men and it couldn't jump well.↵
W: That's amazing!
