But the sun may not be nearly so stable as we suppose. It is now thought to move quickly and irregularly and change
2、 in long-term cycles, growing dimmer and then brighter with each passing year. Some even fear that its frequent changing behavior would have a great influence on the Earth’ s climate.The source of the sun’ s inconstancy is magnetism. Professor William Livingston has developed new theorie
3、s about its magnetic nature.We don’ t yet know what causes sun spots, he says, but we now think they ’ re areas of high level magnetism that come up from the sun’ s interior. So strong is their magnetic pull that the highly ionized gas nearby is not able to transmit energy out. As
4、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, 11-year cycled. Scientists have long formed the o pinion that as the size and number of sun spots increased, the overall energy s
5、ent out by the sun would de crease. 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 scientist
6、s think the world temperature could fall by’ as much as 0.2 during periods of high solar magnetism., enough to cause significant fluctuations in weather patterns.Which of the following statements is supported by the passage（）AThe sun shines constantly and gives out the same amount of energy ev
7、ery year.BThe cause of the sun' s fluctuations is its loss of energy with each passing year.CIt is sure that the energy sent out by the sun will drop when more sun spots appear.DFluctuations in weather patterns are the results of the pull of gravity.2.Passage 2It seems to shine unchangingly, pou
