Let children judge their own work. A child learning to talk does not learn by being corrected all the time:if corrected too much, he will stop talking. He notices a thousand time a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people"s. In the same way,children learning to do all the other things they learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare(比 较) their own performances with those of more skilled people,and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him,or corrcet it unless he was made to. Let him work out,with the help of other children if he wants it,what this word says,what the answer is to that problem, whether this is a good way of saying or doing this or not. If it is a matter of right answer, as it may be in mathematics of science, give him the answer book. Let him correct his own paper. Why should our teachers waste time to do such routine work? Our job should be to help the child when he tells us that he can"t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know. |

Red Dwarf Red Dwarf stars (红矮星) can range in size from a hundred times smaller than the sun, to only a couple of times smaller. Because of their small size these stars burn their fuel very slowly, which allows them to live a very long time. Some red dwarf stars will live trillions of years before they run out of fuel. Then why are red dwarf stars red? Beacuse red dwarf stars only burn a little bit of fuel at a time, they are not very hot compared to other stars. Think of a fire. The coolest part of the fire at the top of the flame glows red, the hotter part in the middle glows yellow, and the hottest part near the fuel glows blue. Stars work the same way. Their temperatures determine what color they will be. Thus we can determine how hot a star is just by looking at its color. Like the Sun, these medium(中等的) -sized stars are yellow because they have a medium temperature. Their higher temperature causes them to burn their fuel faster. This means they will not live as long, only about 10 billion years or so. Near the end of their lives, these medium-sized stars swell up becoming very large. When this happens to the Sun it will grow to engulf(吞 没) even the Earth. Finally they shrink again, leaving behind most of their gas. This gas forms a beautiful cloud around the star called a Planetary Nebula(行星状星云) . When will the Sun expand into a giant, and then shrink leaving behind a planetary nebula? Don"t worry. The sun is only about 5 billion years old. It still has another 5 billion years before it will expand, and then turn into a planetary nebula. The Sun is so hot that when it dies, it will take a long time to cool off. The sun will die in about 5 billion years, but it will still glow for many billions of years after that. As it cools, it will be what is called a white dwarf star. Finally, after billions maybe even trillions of years, it will stop glowing, at that point it will be what we call a black dwarf star. There are still no black dwarf stars in the Universe. |
1. Why do the Red Dwarf stars burn their fuel very slowly? |
A. Because they are small. B. Because they don"t move around. C. Because they are cool. D. Because they reflect light like the moon. |
2. Which of the following best expresses the main idea of Paragra-ph 2? |
A. How red dwarf stars work. B. Why red dwarf stars burn a little fuel. C. Why red dwarf stars are red. D. How temperature determines the color. |
3. Which of the following is closest in meaning to the underlined phrase" swell up"in Paragraph 3? |
A. Become smaller. B. Become larger. C. Keep the same. D. Grow high. |
4. The title on the underline before Paragraph 3 is probably |
A. The Sun B. Yellow Stars C. Planetary Nebula D. Star Temperature |
5. Which of the following websites may this passage be taken from? |

Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (彗星) in the direction of Earth, and its orbit will be changed. Our world will then be sent into a safer, colder part of the solar system. This idea for improving our climate comes from a group of US National Aeronautics and Space Administration( NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet-effectively doubling its working life. The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet of asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy to Earth. "Earth"s orbital speed would increase as a result and we could move to a higher orbit away from the Sun," Laughlin said. Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so "seriously compromise" our biosphere (生物圈)-by cooking us. That"s why the group decided to try to save Earth. The plan has one or two worrying aspects, however. For a stairt, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth-with deadly results. There is also the question of the Moon. As the scientific American magazine points out, if Earth was pushed out of its current position it is "most likely that the Moon would be stripped away from Earth," it states. This would change our planet"s climate. |
1. If the plan is successful, Earth will have a working life of ____ years. |
A. 12 billion B. 6 billion C. 18 billion D. 24 billion |
2. What makes the scientists plan to save Earth? |
A. A few comets are moving to the direction of Earth. B. Earth"s working life is coming to an end soon. C. Earth will become too hot for mankind to keep alive. D. The moon is moving farther and farther away from Earth. |
3. What does the underlined word" compromise" mean? |
A. provide B. benefit C. share D. endanger |
4. What serious problems might the plan cause according to the passage ? |
A. Earth might be moved too far away and man might be frozen to death. B. The comet might hit Earth and man might lose the moon. C. The comet might hit Jupiter or Saturn and never return toEarth. D. Earth"s working life might be greatly shortened. |

Planet Hunter When Geoff Marcy was 14, his parents bought him a telescope. Every night,he would go onto the roof outside his window to see the wonders of the sky. " What excited me most was whether there were planets in other solar systems where life might exist," he says. "I decided to try to find planets orbiting other stars like our Sun. " And he did. " My fellow researcher, Paul Butler, and I found our first planet in 1995 , " Dr Marcy says. " We worked for ten years without finding anything! But we stuck with it, and our patience paid off. " Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr Marcy and Dr Butler also spotted the first "family" of three planets. In June 2002 they announced another discovery: a Jupiter-like(像木星一样的) planet orbiting star 55 Cancri. At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55 Cancri is a major breakthrough: it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun. Why is this important? Scientists think that life on Earth may exist because of two special features (特征) in our solar system. The first is Jupiter. "Because it"s so big, Jupiter pulls comets (彗星) and asteroids (小行星) , or they all come and hit the Earth. " Dr Marcy explains. "Without Jupiter, life on Earth would likely have been destroyed. " A second feature is that Earth is a rocky planet where liquid water, which is necessary for life, can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55 Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr Marcy," We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life ! " |
1. What can we learn about Dr Marcy from the passage? |
A. He is fond of watching Jupiter. B. He is from a scientist family. C. He dislikes working with Paul Butler. D. He is interested in finding life in outer space. |
2. Which of the following is TRUE of the recent discovery? |
A. The planet is not as protective as Jupiter. B. The planet is close to star 55 Cancri. C. The planet proves to be a gas planet. D. The planet is as large as Jupiter. |
3. How many planets orbiting other stars have the two scientists discovered so far? |
A. 100. B. 69. C. 66. D. 65. |
4. Dr Marcy thinks that life may exist in the 55 Cancri system because _____ . |
A. he has found the system similar to the solar system B. he has discovered an Earth-like planet there C. he has discovered a rocky planet there D. he has found signs of life in the system |

A young man named Charles Lyell had different ideas. He wrote a book about them called Principles of Geology. The earth, according to Lyell, was not only thousands of years old, it was millions of years old. As to (关于) the common belief that changes in the earth"s surface happen suddenly because of a single earthquake or flood, he said that this might happen once in a while, but usually these changes took place very slowly. He believed that the surface of the earth had been changing from the beginning of time. The changes, he said, were caused by the long- term action of the winds and seas, and by forces such as volcanoes breaking out under the earth"s surface. Once in a great while he thought, a mountain might appear for the first time after an earthquake. But usually mountains would rise slowly and steadily. Professor Henslow was interested in Lyell"s ideas, but he did not actually believe them. Charles Darwin could not make up his mind about them. But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world. At Cambridge ,Charles Darwin studied just enough to pass the examination, and received his college degree in 1831. During this time, he had become more and more interested in geology. At the end of the school year, he went to North Wales with one of his teachers to examine the rock formations (构成) and to search for fossils (化石). Fossils are the remains of ancient living things. They are usually found fixed in rocks in the earth"s crust (地壳). Fossils may be of animals, such as fish, insects, birds, or humans. They may be of plants from tiny leaves to huge trees. When a living creatures dies, it usually decays (腐烂) or is eaten by animals. However, if it sinks into a riverbed or is quickly covered by the blowing sands of a desert storm, the bones are kept up in the earth. Over many years the soft inner parts of a bone disappear, leaving the inside bellow. Water containing mineral enters into the hollow. Slowly the mineral hardens and makes the bone hard and heavy, like stone. |
1. According to Charles Lyell, it is mainly _____ that theearth has been formed like today"s shape. |
A. from the beginning of time B. past some experiences of big flood C. over a very long period of years D. because of several big earthquakes |
2. Charles Lyell believed the fact that a mountain is formed _____. |
A. more by seas than by volcanoes B. more slowly than suddenly C. more by an earthquake than by winds D. more quickly than steadily |
3. Unlike Professor Henslow, Charles Darwin ____ . |
A. never thought Lyell"s ideas were right B. did made up his mind not to accept Lyell"s ideas C. thought about what the world was then D. thought over Lyell"s ideas and developed them |
4.The main purpose of Darwin"s going to North Wales was to ____. |
A. make a study of fossils B. appreciate the rock information C. do research work into dead animals D. look for plants from tiny leaves to huge trees |
