  How many of us have looked up at the stars and wondered about other worlds?Of course,we know a great deal about the universe now but for people living thousands of years ago,the stars were a mystery(神秘的事物).Astrology(占星术) is one of the world's most ancient (古代的) ideas.It started 3,000 years ago and was used to predict (预言) what would happen to countries and to people in the future.

  Horoscopes and astrology were developed by the ancient Greeks.They believed that the position(位置) of the sun and the planets could affect a person's life and what would happen to them in the future.Astrology is actually a Greek word that means“science of the stars”.Even famous Greek thinkers like Plato thought astrology was important and he studied it carefully.Later Europeans thought that Plato was a genius so they continued to follow his ideas about the stars.

  Some people think that farmers started the horoscope to help them decide when to plant and harvest their crops.They needed to know what time of the year it was.For example,Scorpio can only be seen in the evening sky in the summer.Some historians (历史学家) think that many of the myths (神话) associated with star signs were invented to help farmers remember cultures.People who spent their lives moving from one place to another,like the Mongols,used the stars to tell them when and where to go.

  The Catholic Church(教堂),which was very powerful a long time ago,told people not to take notice of horoscopes.It was not until the seventeenth century that people were able to freely use the horoscope again.Today many people think the horoscope is just fun but some people take it very seriously.

根据短文内容选择最佳答案。(Choose the best answers according to the passage.)

  In 1885, a young doctor named Arthur Conan Doyle opened offices in London.He wanted to be a successful doctor but for some reasons he never found enough patients.To kill the time, he began to write stories and send them to the newspaper.

  Sometimes Sherlock Holmes could solve a mystery without leaving his chair.He listened carefully to the information his customer gave and figured out the answer.At other times he spent days or weeks looking for clues.Sherlock Holmes travelled to different cities and countries to solve the mysteries.Sometimes he wore disguise(伪装衣)and pretended to be an old man, or a sailor.Holmes did anything to find out the answers to the mysteries he was working on.
