[00:42.81]Lesson 1             1 Dialogue

[00:48.46]Four doctors are at a medical conference 1.

[00:53.32]A:Which speech are you going to listen to this afternoon?

[00:58.36]B:I haven't decided 2.There's a talk on cancer that might be quite interesting,

[01:05.23]so perhaps I'll go to that.

[01:08.68]A:Has it got anything to do with your present research?

[01:13.53]B:No.It has nothing to do with it at all.

[01:18.11]C:I'm not sure whether to go to the one about accidents.

[01:23.07]D:It's Dr 3 Stone,isn't it?She's usually good.

[01:29.23]C:Perhaps I'll go to that one.

[01:33.00]D:How did you find the talk this morning?

[01:37.57]A:Very disappointing.Maybe it was useful for some people,but it wasn't for me.

[01:46.21]I doubt if he'll be asked to speak again next year.

[01:50.97]D:I'm not sure that this conference is as good as last year's.

[01:57.13]A:No,I'm sure it's not.

[02:00.79]B:Which speech are you going to?

[02:04.63]D:I'm not going to any.I need some fresh air,so I'm going out for a walk.

[02:13.07]B:Have fun.

[02:28.43]MADAME 5 CURIE(1)

[02:32.58]Madame Curie will always be remembered as the discoverer of radium 6.

[02:38.64]Marie Curie was born in Poland,on November 7th,1867.

[02:45.49]When she was young,she became interested in physics

[02:50.63]and read as many books as she could on the subject.

[02:55.36]At that time women were not admitted to universities in Poland,

[03:01.52]so Marie was determined 7 to go to Paris and study there.

[03:07.56]She arrived in Paris in 1891.

[03:11.79]She had very little money to live on,

[03:15.74]ate very little and was always cold in winter.

[03:21.01]There was a small fire in her room,but she had to carry coal up six floors

[03:29.27]and wear an overcoat in her small room to keep warm.

[03:34.54]She succeeded in taking a first-class degree in physics

[03:38.62]two years after arriving in Paris.

[03:42.67]After graduation she took another degreen in mathematics 8.

[03:47.84]In 1895 she married Pierre Curie,a very bright scientist

[03:55.39]who was teaching 9 at the School of Physics and Industrial Chemistry at Paris.

[04:01.35]Marie started to do research,

[04:05.32]even though she had very little equipment and no money.

[04:10.36]Not long before another scientist had found that uranium gave off rays,

[04:17.02]so Marie decided to study this area for her doctor's degree.

[04:22.48]She gave these rays a new name"radioactive 10".

[04:28.04]One day she made an important discovery.

[04:32.20]There was a certain mineral which was even more radioactive than uranium.

[04:38.36]Therefore,she decided,it must contain some other matter

[04:43.22]that no one had yet discovered.

[04:46.88]In 1898 she discovered the first of these new radioactive minerals,

[04:54.32]which she named"polonium"in honour of her motherland---Poland,

[05:00.67]and on which she wrote a research paper.

[05:04.93]From then on,Marie and Pierre worked together on their research.

[05:10.67]They devoted 11 all their hours to working in their laboratory 12.

[05:15.40]As months went by,the work seemed endless.

[05:20.47]Marie described her thoughts in words much like this:

[05:25.20]"Life is not easy for any of us.

[05:29.04]We must work ,and above all we must believe in ourselves.

[05:35.10]We must believe that each one of us is able to do something well,

[05:40.95]and that,when we discover what this something is,

[05:46.10]we must work hard at it until we succeed.

[05:50.77]One evening in 1902 as she was sitting with Pierre at home,she said to him,

[05:58.22]"Let's go down to the laboratory again."

[06:02.29]It was nine o'clock and they had been there only two hours before.

[06:08.04]They put on their overcoats and went down to the laboratory.

[06:13.00]As they opened the door on the ground floor,Marie said,

[06:18.78]"Don't light the lamps.Look!"

[06:22.82]On the laboratory bench was a glass container from which came a tiny soft light

[06:31.08]It was what they had been working so hard to find:pure radium.

[06:38.16]The matter that the Curies had discovered was radium.

[06:43.51]It looked like ordinary salt,

[06:47.35]but was one million times more radioactive than uranium.

[06:53.70]Its rays could go through every mineral except lead.

[06:59.03]In 1903 Marie received her doctor's degree for her study on radioactive matter.

[07:06.68]Altogether,between 1899 and 1904 she and Pierre wrote 34 articles about their work.

[07:16.74]Marie Curie never made money out of her research.

[07:21.78]She refused to treat these new discoveries as though they belonged to her,

[07:27.66]and instead shared all her knowledge with the whole scientific world.

[07:47.98]MADAME CURIE (2)

[07:51.85]Poloinum and radium were important discoveries.

[07:57.41]Polonium is used to set off a nuclear bomb.

[08:02.77]Radium,because of its powerful 13 radioactive rays,can go deep into the human body.

[08:11.91]Scientists soon discovered that it could be used as a cure for cancer.

[08:19.07]In 1903 Marie and Pierre Curie were given the Nobel Prize for Physics.

[08:28.21]However,there is also a disadvantage which was not discovered for many years.

[08:37.04]Radioactive matter is dangerous to work with

[08:42.08]because it has a bad effect on the blood.

[08:46.52]Pierre and Marie noticed that after years of working with radioactive matter

[08:53.89]their boodies ached 14 and their hands suffered too.

[08:59.06]In fact,radium not only damaged their health

[09:04.91]but also made the laboratory equipment with which they were working radioactive.

[09:12.57]Three of the Curies'notebooks were considered to be too radioactive to touch

[09:19.93]seventy-five years after they were written.

[09:24.61]In 1906 Pierre died in a road accident.

[09:30.67]Marie was deeply 15 shocked by Pierre'sdeath,but was determined to go on working.

[09:38.82]Soon after the accident,she was given Pierre's post at the University of Paris

[09:45.95]as head of the Phy sics Department.

[09:50.21]So Marie Curie became the first woman in France to be a universiy professor.

[09:57.58]In 1911 she received a second Nobel Prize for her research,

[10:04.42]the first person in the world to receive two Nobel Prizes.

[10:10.98]After the First World War Madame Curie travelled to the USA,

[10:18.11]where she was received by the President

[10:22.05]and given a gram 16 of radium for her future work.

[10:27.10]There were soon two Radium Institutes in the world,one in Paris and one in Warsaw.

[10:36.16]Marie was invited to many countries to give speeches about her work.

[10:41.62]For the last ten years of her life she was almost blind.

[10:47.99]The radium with which she had worked for many years

[10:52.85]had caused blindness and illness and finally a disease 17 of the blood.

[10:59.62]She died in Paris at the age of 66.

[11:04.58]Today she is remembered and admired as a scientist.

[11:10.04]But she is also remembered for her determination and courage,

[11:15.71]her willingness to share her knowledge,

[11:19.65]her interest in women's rights,and her medical service during the war
