Peter: Wow! Look at the super Swimming Shark. 
Kate: I like it. You can put it in water and watch! It can swim more quickly(1) than a person(2) but it's not dangerous(3). It has no teeth. 
Peter: Which parrot robot do you like? 
Kate: I like the Talk a lot Parrot. It can repeat 250 words. It can repeat better than the Zippy Parrot. Maybe it can help me when I study. 
Peter: I like the Zippy Parrot. It can repeat well and it can fly better than the Talk a lot Parrot. 
Kate: Do you like the Purple Turtle? 
Peter: Not really. It's too big and it walks more slowly than the Talk a lot Parrot.
Kate: Yes, it's the oldest robot, too. Well, let's go see them.
