人教新课标版高二选修8 Unit3 Inventors and inventions-Reading & listening ppt课件


Reading and listening

Leading in
Do you know about the world famous painting “Mona Lisa? Do you know who painted the great picture?

Do you think Leonardo da Vinci

is really a good painter? What else do you know he is famous for?

《最后的晚餐》

《圣母与圣婴》

《圣安娜与圣母子》

Reading
Was Leonardo da Vinci just a painter?
Read the passage and answer these

questions:
1. Why did Leonardo need to design

things for his employer when he was
such a great painter?

2. Why were Leonardo’s designs different? 3. How did painting help him invent things? 4. Which skill do you think was more important: his drawing for the inventions or his understanding of machines for his painting? Give a reason.

1. The rulers of the small Italian states needed military inventions to help in their wars with each other. They only needed paintings in times of peace. Leonardo lived at a time of great instability, so military inventions were his best way of earning money.

2. His designs were different because

he took things apart and then
improved them. So his designs were

accurate and could be built and
used.

3. While he was studying under Verrochio, Leonardo observed and used a variety of machines, by studying and drawing the machines, Leonardo gained knowledge about their design and structure. His drawing skill enable him to produce clear drawings of his mechanical

ideas easily, many of which can still be used to create perfect working machines. the use of mechanical gears was his most interesting part and he came up with numerous

inventions based on the gear .

4. His understanding of machines for his painting was more important because by understanding how each separate machine part worked, he could improve them and combine them in different ways to improve existing machines, which lead to a lot of inventions.

One of the remarkable things about Leonardo da Vinci was his natural ability in so many subjects. Are you as clever as Leonardo? Find out by

Listening text
WHAT CAN IT BE?

Ellie smith is discussing with one of
her friends Tang Ling, what this invention by Leonardo might be.

ES: Look at this drawings! What do you think this is supposed to be? TL: I don’t know! It doesn’t say, but let’s see if we can work out what it is. ES: OK. Now let’s see. It looks a bit like a tent but has four wheels underneath.

TL: You’re right but when you look at

the second picture with the wheels
you can see that it had a floor to stand on and wheels below that. Do you think it was a roundabout for children?

ES: Good thinking. But the way that he

placed the wheels shows that it
must have been for going forwards

and backwards, not round and
round. No, I don’t think it was a

roundabout.

TL: Let’s look at it again. Do you think it’s made of metal?

The 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 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 artist.

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 been 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 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 can it be? TL: Think again about Leonardo’s life. Can’t you guess?
