(A) Since the beginning of time, man has been interested in the moon. The Romans designed a special day to show admiration and respect to the moon. They called it “Moonday”, or “Monday”,

as we know it today. Later, the great mind of Leonardo da Vinci studied the moon and designed a machine to carry a human to the moon. Leonardo said that one day a great machine bird would take a person to the moon and bring great honour to the home where it was born. Four and a half centuries later, Leonardo’s idea was realized. Apollo 11 took three Americans, Collins, Aldrin, and Armstrong to the moon. The mission(任务)did fill the whole world with great surprise, as Leonardo had said it would. Numerous essays, articles, and books were written about man’s first moon mission. But perhaps the most interesting story was one written before the event over 100 years before. In 1865, French author Jules Verne wrote a story about the first journey to the moon. His story was very similar to the 1969 Apollo 11 mission. Verne’s spacecraft also contained three men — two Americans and a Frenchman. The spacecraft was described as being almost the same size as Apollo 11. The launch(发射)site in Verne’s story was also in Florida. The spacecraft in Verne’s story was named the “Columbiad”. The Apollo 11 command ship was called “Columbia”. His account of sending the spacecraft into the space could easily have been written about how Apollo 11 was sent into the space. 1. Leonardo da Vinci said that a great machine bird would ________. A. bring great honour to the moon ? C. explore the heavens ? B. fly toward the sun ? D. take people to the moon ?

2. Jules Verne wrote his story of a man’s visit to the moon about ________. A. 100 years before the Apollo 11 mission ? C. four and one a half centuries ago ? 3. Verne’s story is very similar to ________. A. the first U.S. space mission ? B. the Apollo 11 mission C. Leonardo da Vinci’s story D. numerous other books on the same subject ? 4. The main idea of this passage is ________. A. some coincidence of mankind landing onto the moon B. Verne’s accurate preview of the future C. the 1969 Apollo 11 moon mission

D. the 19th century science and technology 5. The underlined word “spacecraft” probably means a kind of ________. A. rocket B. plane C. train (B) Many scientists today are sure that life exists elsewhere in the universe — life probably much like that on our planet. They reason in the following way. As far as scientists can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our solar (太阳)system. What we know of life on earth suggests that life will arise wherever the proper conditions exist. Life requires the right amount and kind of atmosphere(大气层) This eliminates(排除)all . those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it. Life also requires regular supply of heat and light. This eliminates double stars, or stars that flash up suddenly. Only single stars that are regular sources of heat and light like sun would qualify. Finally, life could develop gradually only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away. If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next, eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets that are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out. This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.

The distance between a planet and its sun should be right. 9. At the end of the passage the author suggests that ________. A. it is impossible for life to exist on planets B. earthlike life could only exist on a few planets C. life could exist on only one planet in a million D. life could exist on a great number of planets B. our own solar system D. the right distance from the sun

Before we begin our nature walk today, I’d like to

give you a short history of our National Park Service. The National Park Service began in the late 1800’s. A small group of people found the land now called Yellowstone, and after hours of discussion around a campfire they decided that it should be enjoyed by everyone. Two years later the government declared it the first national park in the world. After it became a public park, many other areas of beautiful scenery were set aside and in 1916 these parks began to be managed by the National Park Service. I’m now employed by the National Park Service and I’m on duty at all time to answer
