13.A.recently B.affects C.pattern D.varies E.movesF.warm G.regularly H.special I.effect J.evidenceBig climate changes in the last million years might have come from something very small:dust from outer space.Earth changes between ice ages and warm periods in a (n)(36)C that includes several cycles,including a(37)H one that lasts 100,000years.Scientists(38)A suggested this cycle might be due to changes in the inflow of cosmic dust.
The idea is that Earth(39)E above and below the imaginary orbit that runs through the sun and Jupiter,completing a cycle every 100,000years.So maybe it(40)G meets amounts of dust during each cycle that produce the climate trend.
Now there is some(41)J,from ancient cosmic dust near the Azores islands west of Portugal.The large quantity of the dust rises and falls with a wonderful 100,000year cycle during the period 253,000years to 458,000years ago.Periods of more dust are related to(42)F climates.
But that is a long way from showing that the dust(43)B climate.Some scientists argue that it is not clear how cosmic dust would make the climate warmer while dust from volcanoes is known to make it cooler.They say the cosmic dust is so thin that it is hard to see how it could have any climate(44)I.
分析 本文讲述了宇宙尘埃对地球气候变化的影响,这些影响因素目前尚不能确定.
解答 CHAEGJFBI
36.C.pattern模式,考查名词.根据句意,地球在冰河时期和暖期之间的模式变化包括几个周期.故选C.
37.H.special特殊的,考查形容词.根据句意,特殊情况下,这一变化可持续100000年.故选H.
38.A.recently最近,考查副词.根据文章内容可知,科学家是最近才提出这个周期可能是由于宇宙尘埃的流入而变化的.故选A.
39.E.moves移动,考查动词.根据句意,地球在绕太阳和木星运行的假想轨道上、下方移动.故选E.
40.G.regularly经常,考查副词.前面提到,地球会经常遇到大量的宇宙尘埃.故选G.
41.J.evidence证据,考查名词.根据后面的"from ancient cosmic dust near the Azores islands west of Portugal.The large quantity of the dust rises and falls with a wonderful 100,000year cycle during the period 253,000years to 458,000years ago"可知,这是在为上面的结论提供证据.故选J.
42.F.warm温暖,考查形容词.更多的灰尘与气候变暖有关.故选F.
43.B.affects影响,考查动词.根据后面的"Some scientists argue that it is not clear how cosmic dust would make the climate warmer while dust from volcanoes is known to make it cooler"可知,一些科学家认为,目前尚不清楚宇宙尘埃将如何使气候变暖,而来自火山的尘埃却使其更冷.所以这里是说尘埃对气候的影响.故选B.
44.I.effect作用,考查名词.一些人说宇宙尘埃太薄了,很难看出它会对气候有什么作用.故选I.
