【正文】 magic nature. ―We don39。t yet know what causes sun spots,‖ he says, ―but we now think they39。re areas of highlevel magism that e up from the sun39。s interior. So strong is their magic pull that the highly ionized gas nearby is not able to transmit energy out.‖ As a result, these areas send out less heat and light and thus appear from Earth to be almost dark irregular surface patches. Sun spot activity generally fluctuates in steady, 11year cycles. Scientists have long formed the opinion that as the size and number of sun spots increased, the overall energy sent out by the sun would decrease. Indeed, recent studies confirmed it, revealing that during peak periods of sun spot activity, the Earth experiences a small drop that can be seen clearly in received solar energy. Could such a small drop in energy have an effect here on Earth? Perhaps. Some scientists think the world temperature could fall by as much as ℃ during periods of high solar magism enough to cause significant fluctuations in weather patterns. 1. According to the passage, it is believed that the sun ______.【 直接法 】 [A] moves in a quick but steady way year after year [B] sends out less and less heat and light with each passing year [C] radiates the same amount of light every year [D] might have a strong influence on the weather patterns 2. Which of the following is NOT true of the sun spots? 【 直接法 】 + 【 排除法 】 [A] They are caused by the magic pull from inside the sun. [B] They are areas of highlevel magism. [C] They are actually black holes in the sun. [D] They reach their peak in a cycle of 11 years. 3. It can be inferred that Livingston ______. 【 直接法 】 + 【 排除法 】 [A] thinks he has discovered a new possibility in the link between the sun spots and the weather on the Earth [B] has great doubts about the theory that the sun39。s frequent changes have an influence on the Earth39。s climate [C] has been recently informed by other scientists of the possibility that more sun spots will appear [D] does not think the causes of the sun spots will be fully revealed by scientists in the near future 4. The statement supported by the passage is ______. 【 直接法 】 [A] the sun shines constantly and gives out the same amount of energy every year [B] the cause of the sun‘s fluctuations is its loss of energy with each passing year [C] it is sure that the energy sent out by the sun will drop when more sun spots appear [D] fluctuations in weather patterns are the results of the pull of gravity 5. The best title for the passage is ______. 【 直接法 】 [A] Fluctuations in Weather Patterns [B] Magism and the Sun Spots [C] The Size and Number of Sun Spots [D] Livingston39。s New Theory about the Earth39。s Climate P322P2（作家歐文） Washington Irving was America‘s first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. 1. The main point of the first paragraph is that Washington Irving was ___________.
