and Hewish developed radio telescope systems for the location of weak radio sources, and they shared the Nobel Prize for Physics in 1974. A radio telescope is usually made up of:
? One or more antennas to collect the radio waves. Most antennas are made in
the shape of a dish to collect and reflect, the radio waves to the sub-reflector, in the same way as a curved mirrorfocuses visible light to one point.
? A receiver and amplifier to receive the radio waves from the sub-reflector, and make these weak radio waves strong enough to be recorded and turned into electronic signals. To make an amplifier sensitive enough, it is usually cooled to, very low temperatures (e. g. as low as -270℃）.
? A recorder to keep a record of the electronic signals. Most :radio telescopes today keep the signals to the computer's memory disk for astronomers to analyze later.
Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch Radio wavelengths are much longer than those of visible light,
and the radio waves from deep space are always weak. To catchthese waves, radio telescopes usually have huge antennas. The sizes of most antennas in use today are around50 to 300 metres in diameter. The antenna of FAST in Guizhou, China, the latest and largest radio telescopein the world, is 500 metres in diameter, as large as the size of 30 football fields.
To avoid interferences, and keep the telescopes sensitive, radio telescopes
are built in places where thereare no human radio waves or electronic signals. For example, FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town.
Radio telescopes create pictures of the sky, not in visible light, but in radio waves. This is extremely useful, because there are objects that can't be seen, objects that we wouldn't even know without radio telescopes.

A long time ago, Francois Millet. Claude, Carl and I were young artists - very young artists - in fact.
Yes, Francois Millet. the great French artist, was my friend.
Millet wasn’t any greater than we were at that time. He didn't have any fame, even in his own village.
We were all poor though we had stacks and stacks of as good pictures as anybody
in Europe painted. Once aperson ever offered four francs * for Millet’s \which he intended to sell for eight.
It was a fact in human history that a great artist would never be acknowledged* until after he wasstarved and dead. His pictures climbed to high prices after his death.
Then we made a decision that one of us must die, to save the others and himself. Millet was elected * .elected to die.
During the next three months Millet painted with all his might, enlarged his stock all he could, notpictures, no! sketches, studies, parts of studies, fragments of studies, of course, with his cipher * on them.
They were the things to be sold.
Carl went to Paris to start the work of building up Millet's name. Claude and I went to sell Millet's smallpictures and to build up his name as well.
We made Millet a master. I always said to my customer, \
picture of Francois Millet'sat all, for he is not going to live three months, and when he dies his pictures can't be had for love or money. \
Claude and I took care to spread that little fact as far as we could. Carl made friends with the correspondents, and got Millet's condition reported to England and all overthe continent, and America, and everywhere.
The sad end came at last, Millet died, not really. He became Theophile Magnan. The pictures went up. There's a man in Paris today who owns seventy Millet pictures. He paid us twomillion francs for them. Do you still remember the \Carl sold it for twenty-two hundred francs.And as for the bushels of sketches and studies which Millet produced in the last six weeks, well, it wouldastonish you to
know the figure we sell them at nowadays.
We are no longer artists and Millet dead.
37.''Why did the four friends decide to elect one of them to die?

Children with the defect need all the help. Although many sufferers are accepted by their families, sadly, others are not. In some countries, children with this defect are often abandoned at birth because their parents feel ashamed of them or cannot afford the operations. The good news is that the operation is not difficult. It takes less than an hour and costs the family nothing. The charity raises money and finds the right medical volunteers to perform the operations.
A Smile Train doctor from the UK said, “Each child who has the operation is given a second chance at life. After years of staying at home, the children can finally go to school and be happy. Every year I perform hundreds of operations free of cost through Smile Train. Some of the stories I have heard are quitesurprising.
One newborn baby girl was found abandoned on a train. Luckily for her, she was found and adopted (收养) by a passenger. This lady then heard about
Smile Train and brought the baby to ourhospital. I did the operation and
gave hope to the family. Experienced doctors like me share our skills with local doctors. In this way make sure that these operations will always be available.\
