[00:26.36]Who were the famous scientist described on the tape?

[00:30.93]1.This one is one of the greatest scientist of all times.

[00:37.59]Even her name tells you that she likes science.

[00:42.84]A good scientist should want to find out answers and ask many questions.

[00:50.78]In other words,they should be curious.

[00:54.94]This woman was certainly curious.

[00:59.30]Together with her husband she tried to learn the secrets of radio activity.

[01:06.06]The couple were award the Nobel Prize for physics in 1903.

[01:12.91]Eight years later,she received the second Nobel Prize,this time for chemistry.

[01:20.27]2.It is said this English Gentleman was sitting in his garden one day,

[01:27.43]when suddenly he was hit by a falling apple.

[01:32.58]The story is probably not true,but this man did mention,

[01:38.53]that he got one of his best-known 1 ideas

[01:43.11]while watching apples fall from a tree.

[01:47.55]His name makes you think that he was not too interested in all things.

[01:55.12]He discovered the force of gravity 2.

[01:59.85]and he drew up the system of how objects move.

[02:05.62]His laws for motion 3 are still used in physics today

[02:12.18]at least in schools and universities.

[02:16.93]3.Food is what sets this great mind on fire -- rice to be exact.

[02:24.59]This great mind has spent most of his life looking for ways to help farmers grow more rice.

[02:31.75]So that all of us will have enough food to eat.

[02:36.32]He is known as the Father of Modern Rice.

[02:41.28]But because of his long friendship with all the farmers in China,

[02:46.74]he would rather be known as 'the Farmer'.

[02:54.79]Work book   Unit one  Listening

[03:00.35]Many animals and plants have developed ways to solve problems that are similar to the ones we humans have to deal with.

[03:08.81]Part One

[03:11.48]Scientists often look at nature in order to find new ideas.

[03:17.72]In ancient times,Chinese scientists studied how spiders made silk.

[03:24.38]Modern scientists are interested in the spider too.

[03:29.42]The spider can make silk that is much stronger than most man-made 4 materials.

[03:35.69]Spider silk doesn't break easily,instead of breaking,it gets longer.

[03:42.82]Best of all,

[03:45.88]the spider produces the silk without the use of dangerous or poisonous chemicals

[03:52.96]If we could learn to use the technique,

[03:57.11]we might be able to use the strong silk to make things like seat-belts and wires that hold up bridges.

[04:04.56]Part Two

[04:07.33]There are many other examples of how new technology has been developed by learning 5 from nature.

[04:14.48]A group of German scientists wanted to find out why leaves and flowers are able to stay so clean.

[04:23.03]They decided 6 to take a closer look at the white lotus 7,

[04:28.07]a flower that is know for it's cleaning leaves.

[04:33.35]At first,the scientists believe that the very flat leaf

[04:38.91]would be better with stain 8 clean.

[04:42.67]However,when they looked closely 9 at the white lotus,

[04:47.71]the scientists saw that the leaf was in fact covered with tiny hairs and needles.

[04:54.09]The needles and hairs collect the dust that falls on the leaf.

[04:59.55]So that a rain drop can easily wash it out.

[05:03.80]The German scientists use this technic to design a new kind of paint.

[05:10.15]The new paint could keep out as looking clean for years.

[05:15.14]Scientists also believe

[05:18.59]that the butterfly could teach us a way to keep our computers cool.

[05:24.26]A computer must be kept cool to function well.

[05:29.12]The fans we use today are not always good enough.

[05:33.84]The butterfly is cold-blooded and must change its body temperature all the time.

[05:40.32]Scientists have found that there are small parts on the two wings

[05:45.68] of the butterfly uses to change its temperature.

[05:50.22]If scientists can learn how it has done,

[05:54.38]it maybe possible to use the same method to keep computers from becoming too hot
