1 . Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.
However, Halley had a friend named Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.
Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.
This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction of what comet would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.

Seeing there were so many farmers struggled to feed themselves, the scientist decide to devote his life to helping keep the world free of hunger. Since then, he has been leading happy life, though many people can’t understand his behavior.
He always works on the farm, chatting with the farmer, which it can account of his sunburnt face. He as well as his team was awarding many honors. Besides, they are not satisfying with the present achievements. They hold the belief which the more they devote, the few pepole go hungry.

The man inspiring me most is Qian Xuesen, who is known for the father of China’s space technology and died at age of 98 in 2009.
After graduate from university in 1934, Qian went to the US for further education. After the PRC was found, he returned back to China to help develop China’s national defense. He gave all their life to China’s aerospace science and technology and make great achievements. He set up China’s first missile-and-rocket research institute, that later helped start China’s space program.
There is no doubtful that he will be remembered by the Chinese forever for his great contribute.
6 . Thomas Edison was one often said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius.“ There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.
But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.
Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.
Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

| A．very much interested in nature |
| B．interested in discovering the secrets of nature |
| C．interested in changing people’s ideas |
| D．uninterested in making people happier by discovering the secrets of nature |
| A．he could be happy if he was a genius | B．genius plays the most important part in one’s success |
| C．hard work could do better than genius | D．genius could do better than hard work |
| A．life is too short for Edison to invent more for human beings |
| B．Edison made 100 inventions in his life |
| C．Edison was able to live and work for 100 years |
| D．People of his time were ready to give Edison another 100 years’ work |

As we all know, the father of hybrid rice---Yuan Longping cultivated hybrid rice and fed millions of people all over world. He was one of the greatest scientist in China. Unluckily, he pass away at the age of 91,in May 22,2021.However,her dream will always inspire many people. His dream was that he could enjoy the shade under the hybrid rice. There is no doubt that dream is very much important. As for myself, I would like to become a usefully person like Yuan Longping which did valuable contribution. What I can do is that I will study hardly and learn more knowledge. I hope I can achieve my dream one day but I will never give up my dream no matter how difficult it is.
Known as the "father of hybrid rice"，Yuan Longping is one of China's
