20、______________________________________________________________________________________________________________________________________________________________________________________________________________________,early

21、 car,the picture seems to show a vehicle that can move backwards and forwards, has four wheels and can take people for a ride. It does not have beds or room for beds, so it cannot be a caravan. It is made of metal so it

22、cannot be a tent. It does not go round and round so it cannot be a roundabout.,WHAT CAN IT BE?,Ellie Smith is discussing with one of her friends Tang Ling, what this invention by Leonardo might be.,Listening text,ES: Loo

26、wheels seem to have handles to move them.,ES: In that case it must have been large enough for more than one person. You would have needed four people—one to move each wheel. So it cannot be a tent as that

27、is made of cloth.,TL: Yes, I think you’re right.ES: It also seems to have something like sticks coming out of the body. Do you think they are for decoration?TL: Perhaps. That is possible as we know Leonardo was an art

28、ist.,ES: Yes and if that were the case, perhaps it was for fun for the family. It could carry four people to move the wheels and then another one or two children to help. Maybe six altogether.TL: Wow! So it must have be

29、en made of metal. Nothing else could carry all that weight.,ES: True! The wheels must be made of wood or metal.TL: Do you think it’s a caravan?ES: Yes, that makes sense. It would be big enough but there doesn’t seem

30、to be any room to sleep in it. And it wouldn’t be very easy to park for the night. So perhaps it was an early car?,TL: Well, let’s look in the guidebook. Oh no—it seems you’re not correct.ES: Gracious. So what on earth
