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（氣象學家）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（太陽的）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 文章講述了科學家對世界氣候變化進行的預測及影響因素的推測．

解答 56-59 ADBC
56題答案是A．細節(jié)理解題．根據(jù)Some scientists imagine that this could even mean the beginning of another ice age一些科學家認為這將是另一個冰河世紀的開始，即氣候在變冷．故選A．
57題答案是D．細節(jié)理解題．根據(jù)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科學家無法確定氣候將發(fā)生什么變化及對世界帶來什么影響．故選D．
58題答案是B．推理判斷題．根據(jù)Meteorologists believe that clouds may be an important factor in regulating the amount of solar（太陽的）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．氣象學家相信云彩是控制太陽熱量的一個重要音素，其他的可能性是人類的工農(nóng)業(yè)類型影響著天氣．regulates應該是表示"控制，影響"，即和controls的意思相近，故選B．
59題答案是C．文章大意題．文章主要講述了科學家對氣候變化的預測，故選C．
