Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit（轨道） 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 Isaac 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(椭圆形).

    Now Halley set to work. He figured out(解决，计算出)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 appearance had been 75 to 76 years apart.

    This seemed very strange to Halley. Three 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 to make a prediction(预言)of what would happen in the future. He decided that this 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 had been called Halley’s comet, in his honor.

Noah Webster, born on October 16, 1758 , is known for The American Dictionary of the English Language. He has been called the " Father of American Scholarship and Education. " His " Blue-Backed Speller" books were used to teach spelling and reading to five generations of American children. But how much .do you know about him beyond that?

   At the age of 16, Noah Webster began attending ,Yale College. Unfortunately, he spent his four years at Yale during the American Revolutionary War, and, because of food shortages, many of his college classes were held in Glastonbury, Connecticut. Later, he served in the army.

Having graduated from Yale in 1778, Webster wanted to continue his education in order to earn his law degree. He had to teach school in order to pay for his education. He set up many small schools that didn't survive, but he was a good teacher because instead of forcing his students to learn, like most teachers did, he rewarded them. He earned his law degree in 1781, but did not practice law until 1789. Once he started he found the law was not to his liking.

   Webster did not have much money. In 1793 , Alexander Hamilton lent him $ 1500 to move to New York City to edit a newspaper. In December, he founded New York ' s first daily newspaper, American Minerva, and edited it for four years. For decades, he published . textbooks, political essays, a report on some diseases, and newspaper articles for his party, He wrote so much that a modern list of his published works required 655 pages .Noah Webster died on May 28, 1843 and was buried in the Grove Street Cemetery.

"Colour" and "color"，"favourite" and "favorite"... Have you ever wondered why Americans spell those words without a "u"? Is it because they are lazy?
Of course not. In fact，the difference in spelling was created by Noah Webster (1758-1843). He is a teacher who reformed English to make American identity stronger. Linguists (语言学家) celebrated his 250th birthday on October 16. After the Revolutionary War (1775~ 1783)，Webster believed that Americans should have their own dictionary，rather than rely on British versions (版本). He dropped the British "u" in some words. And he changed "centre" into "center" for children to learn English by spelling words more like they sounded.
Webster wasn't shy about expressing his opinions. In defining (定义) preposterous (unreasonable)，he wrote: "A republican government in the hands of females is preposterous."
Webster spent 28 years on the project before completing the 70,000-word dictionary in 1828 with his American-style spellings. He also added local words. His dictionary was widely used in schools. Linguists believed it helped a new nation achieve unity and cultural independence at a time when most were focused on political freedom.
"He was the shaper of our language and the shaper of American identity，"said Joshua Kendall，who is working on a biography (传记) about Webster. "He at last bonded (联合)us through our language."
