Plutos recent departure from the classical planet family clearly proves that size really matters.Astronomers voted on August 24 to give a definition to the word “

27、planet“, and Pluto turned out to be only a “dwarf planet“ (矮行星). After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a “planet“ at a conference of the International Astronomical Union (IAU). According to the definition, a planet must have a clear neighbo

28、rhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptunes. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptunes gravity when the two planets get closer.Accord

29、ing to IAU, a “dwarf planet“ should have an orbit around the sun, It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight “classical planets“, to

30、gether with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Astronomers sent an advanced telescope into space, and found a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As t

31、hey continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto.It seems that even if the IAU had kept Plutos status as a planet, the classical theory of nine planets in the solar syst

32、em would have had to be changed. More dwarf planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets.（分数：10.00）(1).The sentence “It is always hard for a small fish to live in a big pond“ quoted at the beginning of the passage is used

33、to _. A. tell us small fish can hardly survive in the big pond B. tell us the size of an object really matters C. mean that small planet can hardly exist in the solar system D. explain the disappearance of Pluto in the solar system（分数：2.00）A.B.C.D.(2).According to the passage, Pluto is _. A. a “dwar

34、f planet“ which has a clear neighborhood around its orbit B. a satellite of Neptune which was discovered in 1930 C. the smallest planet in the solar system D. a “dwarf planet“ which has an orbit around the sun（分数：2.00）A.B.C.D.(3).According to the new classification, the solar system includes _. A. e

35、ight classical planets and forty one dwarf planets B. nine classical planets and at least forty one dwarf planets C. eight classical planets and a number of dwarf planets D. 1,000 objects（分数：2.00）A.B.C.D.(4).From the last paragraph we can infer that if IAU kept Plutos status as a planet, the number

36、of planets in the solar system would he _. A. eight B. nine C. less than nine D. more than nine（分数：2.00）A.B.C.D.(5).Which of the following statements is NOT true according to the passage? A. According to the definition of a “planet“, if Pluto were bigger it would not have left the classical planet f

37、amily. B. The definition of “planet“ was determined by over 2,500 astronomers. C. Pluto has a special orbit which overlaps with Neptunes because it is so small as to be attracted by Neptunes gravity when the two planets get closer. D. A “dwarf planet“, which must not be a satellite without a clear n

38、eighborhood around its orbit, should have an orbit around the Sun.（分数：2.00）A.B.C.D.八、BText 2/B(总题数：1，分数：10.00)Do you find getting up in the morning so difficult that its painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cyc

39、le.During the hours when you labour through your work you may say that youre “hot“. Thats true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No

40、one has discovered why this is so, but it leads to such familiar monologues as, “Get up, John! Youll be late for work again!“ The possible explanation to the trouble is that John is at his temperature and energy peak in the evening. Much family quarrelling ends when husbands and wives realize what t

41、hese energy cycles mean, and which cycle each member of the family has.You cant change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe youre sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some e

42、xtent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This wont change your cycle, but youll get upstream and work better at your low point.Get off to a slow start which saves you

43、r energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy

44、or concentration for your sharper hours.（分数：10.00）(1).If a person finds getting up early is a problem, most probably _. A. he is at his peak in the afternoon or evening B. he is not sure when his energy is low C. he refuses to follow his own energy cycle D. he is a lazy person（分数：2.00）A.B.C.D.(2).Wh

45、ich of the following may lead to family quarrels according to the passage? A. Unawareness of energy cycles. B. Familiar monologues. C. Attempts to control the energy cycle of other family members. D. A change in a family members energy cycle.（分数：2.00）A.B.C.D.(3).If one wants to work more efficiently
