Men have always wondered about the earth they live on and about the ①_____ above them.

When early men looked at the night sky, they asked themselves a lot of questions. They looked at the moon, and wondered what this strange bright object in the sky was. They did not understand why it changed its shape from night to night. They looked at the stars and planets. They also wondered why some of them changed their positions, while others did not.

②他们也思考地球的形状。 Most early people believed the earth was flat.

③In different parts of the world, there were different ideas about the universe. The ancient Greeks were the first people to study the universe more scientifically. In the sixth century BC Pythagoras put forward the idea that the world was round. However, he could not explain why people at the bottom of the world did not fall off.

It was not until the sixteenth and seventeenth centuries that scientists found the answers to some important questions. ④With the help of Galileo’s telescope, people could see the sky more clearly, and find the positions of the stars and planets. Finally in 1665, Isaac Newton explained to the world what gravity (重力) was and people at last understood why they did not fall off the earth.

5.Which of the following shows the structure (结构) of the passage?

（①=Paragraph 1, ②= Paragraph 2, …）

One day when Isaac Newton was reading a book under an apple tree on the farm，an apple fell down and hit him on the head．For most people that would be the end of the story，but not for Newton．Why did the apple fall out of the tree? Does everything fall? What makes things fall? Can anything stop things from falling? Are the sun，moon，and stars falling? Why don't they ever hit the ground?

Newton spent many years answering these questions by thinking and doing experiments．He made up the law of gravity（引力定律）．According to this law everything pulls everything else to itself by a force（力）called gravity．How strong that force is depends on how heavy the things are and how close together．

Newton's law of gravity not only explained how things fall on earth，but how planets move around the sun and how moons move around planets．A friend of his，Edmund Halley，decided to try Newton's theory（理论）on comets（彗星）．People had been studying comets for hundreds of years but failed to understand them，so he decided to study their reports and compare them to Newton's theory．

Up till then people had thought that comets just came and went，and that nobody could know when or why．But Newton's law of gravity gave rules that Halley could use to study the records of comets．He found some reports of a big bright comet that he was sure was the same one，coming back every 75 years．He predicted（预测）when it would come back next．

Halley's prediction came true．Tile comet appeared at the right time as he predicted using Newton's ideas．This was enough to convince anybody who still didn't believe Newton．Halley's Comet has come a few times since then，always right on time．You'll be able to see it on its next trip near the sun and earth when you're old enough to be a grandparent．

3．According to the writer，Newton was especially different from others in that _______．
