A successful scientist is generally a good observer. He makes full 1 of the facts he observes. He doesn’t accept ideas which are not 2 on obvious facts, and therefore refuses to accept authority as the only 3 for truth. He always 4 ideas carefully and makes experiments to prove them.
The rise of 5 science may perhaps be considered to 6 as far back as the 7 of Roger Bacon, the wonderful philosopher of Oxford, who live 8 the years 1214 and 1292.

学习啦在线学习网 Galileo, however, who lived more than 300 years later (1564-1642), was the greatest of several great men, 12 in Italy, France, Germany, or England, began by 13 to show how many important 14 could be discovered by observation. Before Galileo, learned men believed that large bodies fell more 15 towards the earth than small ones, 16 Aristotle said so. But Galileo, going to the 17 of the leaning Tower of Pisa, let fall two 18 stones and proved Aristotle was wrong.

A
Albert Einstein was probably the most famous scientist of the twentieth century. He changed scientific thinking in the modern world. He is generally considered as the greatest physicist who ever lived. What's more, he devoted a lot of his time and energy to working for human rights and progress.
学习啦在线学习网 In 1933, while Einstein was visiting England and the United States, the Nazi government of Germany took all his things away, including his position and his citizenship. Einstein then settled down in the United States. In 1939, Einstein, who loved peace—afraid of a world in which only Hitler would had an atomic bomb—tried hard to persuade President Franklin D.Roosevelt in a famous letter to have the United States start uranium research. That Germany, after all, had no bomb, and that the first bomb would fall on Japan, could not have been expected. After the war, Einstein never stopped working for peace and reducing the number of soldiers in the world.
学习啦在线学习网 Although he wasn't connected with any accepted religion,Einstein felt that trust in a personal God was too special an idea to be suitable to the God at work in this universe, but he never believed that the universe was one of chance or disorder. The universe to him was one of pure law and order.He once said,"God may know everything,but he is not hateful."

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists have also sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such
Message.
学习啦在线学习网 Scientists are using powerful radio telescopes to listen to signals from about 1,000 stars, all within 100 light years off Earth. In addition, they will scan(扫视) the entire sky to"listen" for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way Galaxy(银河系), scientists find that five percent are like our sun. Perhaps half of them have a planet like Earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution(进化) of life. Based on the inhabitable(可以居住的) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent(有智力的) life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
学习啦在线学习网 Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization much more advanced than ours have developed. Perhaps these civilizations send us no signals;perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
5. How many planets in the Milky Way Galaxy might be inhabitable?
学习啦在线学习网 A. 5 billion. B. 10 billion. C. 15 billion. D. 200 billion.
学习啦在线学习网 6.Which of these statements is true based on the information in the passage?
A. Our sun family is about 20 billion years old.
学习啦在线学习网 B. Most scientists believe that there is intelligent life on other planets.
学习啦在线学习网 C. Scientists try to send radio and television messages in order to get in touch with someone in outer space.
D. Scientists don't believe that there might be life on other planets.
