[00:19.30]1.Yingtian had a problem this morning.

[00:24.27]He is telling Zhenhui about it.

[00:26.83]Listen and answer the questions.

[00:29.70]Zhenhui:Hi,Yingtian.How are you?

[00:32.63]Yingtian:I'm OK now,

[00:35.37]but Mum and I were almost late for my swimming

[00:38.14]competition this morning.

[00:39.99]Zhenhui:Why?

[00:42.14]Yingtian:We drove under a low bridge

[00:44.17]and suddenly we couldn't move!

[00:46.73]Zhenhui:Oh no!Why not?

[00:49.37]Our truck was too high to go under the bridge.

[00:52.24]Can you guess what we did?

[00:54.28]Zhenhui:No,I can't.What did you do?

[00:57.44]Well,first we thought about putting lots of rocks

[01:01.31]on the truck to make it heavier.

[01:03.95]Zhenhui:That sounds like hard work!

[01:06.22]Yes,especially,as there were many big rocks beside the road

[01:10.27]but only a few small ones.

[01:12.62]Then we had a better idea.

[01:15.18]We let some air out of the truck's tryres,instead.

[01:19.15]You let some air out of the tyres!Why?

[01:23.51]The truck was a few centimetres hower after that.

[01:26.67]It was low enough to go under the bridge.

[01:29.55]Zhenhui:That was very clever!

[01:31.40]Lesson 6

[01:33.36]1.Read about Newton and light.

[01:37.52]Match the paragraphs with the pictures.

[01:40.15]1.When Isaac Newton (1642-1727) was young,

[01:45.90]everyone thought that there were two colours in light,

[01:48.77]black and white.

[01:50.81]Newton liked to ask questions.

[01:53.37]He asked,'Is it true that there are only two colours?'

[01:56.92]2.At the age of 24,he said,

[02:00.08]'I don't think that it is true.

[02:02.15]I guess that all colours are part of white light.'

[02:05.31]He had to prove his guess.

[02:08.26]3.How could he prove it?

[02:11.32]I think that when white light goes through a glass prism,

[02:15.08]it will make different colours.

[02:17.35]I think that these different colours will make white light

[02:21.19]when they go through another glass prism.'

[02:23.75]4.He decided 1 to do a test.

[02:26.91]What did he learn?

[02:28.66]First,he learned 2 that light

[02:30.94]has at least seven different colours.

[02:33.50]Second,

[02:35.25]he learned that these colours make white light again.

[02:38.20]5.Newton said,'I will tell people about my test.

[02:42.46]'Only a few people said,'I understand you!'

[02:45.69]Fewer people said,'I agree with you!'

[02:48.57]'Today,everyone knows he was right.

[04:37.26]1.Where did dinosaur bones come from?

[04:41.70]Read the story and match the pictures with the ideas.

[04:44.94]For hundreds of years,

[04:46.80]people have found dinosaur bones

[04:49.15]in many different parts of the world.

[04:51.32]But,until scientists did tests on them,

[04:54.06]only a few people knew

[04:56.02]where these large bones really came from.

[04:59.05]In ancient China,

[05:00.70]people thought that dinosaur bones were dragon bones(1).

[05:04.35]In parts of Europe,

[05:06.39]people thought that they were the bones of giant people and animals(2).

[05:10.44]The ancient Greeks

[05:12.40]found dinosaur bones when they dug for gold.

[05:15.64]These dinosaurs 6 had beaks 7 like birds.

[05:18.69]The Greeks thought that they must be griffins(3).

[05:21.54]In Vietnam,

[05:23.50]people believed that a giant water buffalo

[05:26.24]carried the sun across the sky each day.

[05:29.80]They thought that dinosaur bones

[05:31.83]were the giant water buffalo's bones(4).

[05:34.39]American Indians

[05:35.86]thought that the bones came from giant snakes.

[05:38.81]They believed that these

[05:40.56]snakes dug holes in the ground and died in them (5).

[05:44.01]3.Listen to an interview with the famous scientist,

[05:49.47]Dr Hong Yifeng,and write the correct dates in the table.

[05:53.91]TV reporter:Hello.Today,I am talking to Dr Hong.

[05:57.85]He works 8 at the University of Science

[06:01.72]and Technology and is an expert on bird fossils 9.

[06:04.46]Dr Hong,have you always like birds?

[06:07.93]Yes.I was born in Hangzhou in Zhejiang province in 1957.

[06:15.48]When I was a child,

[06:18.04]Hangzhou was full of birds and animals.

[06:21.20]My favourite hobby was walking in the countryside

[06:25.46]looking for new and unusual things

[06:28.70]When did you first become interested in bird fossils?

[06:32.57]I was interested in fish fossils,first.

[06:36.70]Then,in 1990,

[06:39.86]I found a large number of bird fossils

[06:43.20]and started to study them.

[06:45.26]What is your favourite fossil?

[06:47.82]Dr Hong:In 1993,

[06:50.67]I was lucky enough to see the Confuciusornis fossil.

[06:54.80]The Confuciusornis

[06:56.86]was one of the earliest birds on Earth.

[07:00.02]TV reporter:Where did you study science?

[07:02.77]I studied at Qinghua University in Beijing.

[07:06.92]Then,in 1995,I went to Europe to study.

[07:12.48]TV reporter:What did you do after that?

[07:14.52]In early 2000,I returned to Beijing to work.

[07:18.57]I hope to learn
