Question

15．There is a definite possibility that the climate of the world may be changing．Some scientists imagine that this could even mean the beginning of another ice age．The effects of such a change in climate on the human population of the world would be amazing．
  Recent research suggests that the general warming trend of the past hundred years or so may be coming to an end．During the past ten years，meteorologists（气象学家）tell us the average temperature of the earth has dropped about one degree Fahrenheit．This does not seem like much，but it could have effects on wind and rain patterns which influence the overall weather picture．If these patterns change a lot，it could mean that certain regions of the world may continue to have long droughts（干旱）while others will possibly suffer from widespread flooding．
  What regulates the climate is not exactly known．Meteorologists believe that clouds may be an important factor in regulating the amount of solar（太阳的）heat held by the earth，which in turn determines the temperature of the planet．Another possibility is that man's industrial and agricultural methods may be affecting the natural weather patterns．However，the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the world's population．
56．According to the text，the climate of the world seems toA．
A．be getting colder
B．be getting warmer
C．remain the same in the past ten years
D．have good effects on the world's population
57．According to what you have read，which of the following is true？D
A．Another ice age will come soon．
B．Man's activities have no effect on the climate．
C．People don't care about the changing climate．
D．Scientists are not yet sure about the reason for the changing climate．
58．The underlined word"regulates"in the third paragraph probably means"B"．
A．manages          B．controls        C．prevents       D．protects
59．The best title for the text would beC．
A．Droughts and Floods        
B．Meteorologists
C．Changing Climate          
D．Solar Heat．

Answer 1

分析 文章讲述了科学家对世界气候变化进行的预测及影响因素的推测．

解答 56-59 ADBC
56题答案是A．细节理解题．根据Some scientists imagine that this could even mean the beginning of another ice age一些科学家认为这将是另一个冰河世纪的开始，即气候在变冷．故选A．
57题答案是D．细节理解题．根据However，the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the world's population科学家无法确定气候将发生什么变化及对世界带来什么影响．故选D．
58题答案是B．推理判断题．根据Meteorologists believe that clouds may be an important factor in regulating the amount of solar（太阳的）heat held by the earth，which in turn determines the temperature of the planet．Another possibility is that man's industrial and agricultural methods may be affecting the natural weather patterns．气象学家相信云彩是控制太阳热量的一个重要音素，其他的可能性是人类的工农业类型影响着天气．regulates应该是表示"控制，影响"，即和controls的意思相近，故选B．
59题答案是C．文章大意题．文章主要讲述了科学家对气候变化的预测，故选C．
