The strangest weather of last year was possibly not on Earth, but on the Sun. Every 11 years【C1】______the Sun goes through a cycle of sunspots—actually magnetic storms erupting across its surface. The number of sunspots【C2】______its minimum in 2007 and【C3】______have increased soon afterwards, but the Sun has remained strangely quiet since then. Scientists have been baffled as weeks and sometimes months have gone by without a single sunspot, in【C4】______is thought to be the deepest solar minimum for almost 100 years.
This【C5】______of solar activity means that cosmic rays reaching Earth from space have increased and the planet’s ionosphere in the upper atmosphere has sunk in【C6】______, giving less drag on satellites and making collisions between them and space junk more likely. The solar minimum could also be cooling the climate on Earth because of slightly diminished solar irradiance. In fact, the quiet spell on the Sun may be【C7】______some of the warming effects of greenhouse gases, accounts for the somewhat flat temperature trend of the past decade. But【C8】______if this solar minimum is offsetting global warming, scientists stress that the overall effect is relatively slight and certainly will not last.
The Sun has gone into long quiet spells before. From 1645 to 1715 few sunspots were seen during a period called the Little Ice Age, when short summers and savage winters often plagued Northern Europe. Scotland was hit particularly【C9】______as harvests were ruined in cold, miserable summers, which led to famine, death, migration and huge depopulation. But whether the quiet Sun was entirely to blame for it remains highly【C10】______.
【C10】
选项
A、certain
B、unlikely
C、likely
D、uncertain
答案
D
解析
根据第一段第三句话:2007年太阳黑子的数量达到了最低点,此后它本来应该迅速回升,但是从那时起太阳却表现得出奇平静。据此可知:空格所在部分的大意为:但是平静的太阳到底该不该由于它的极度反常而受到人们的指责呢?分析各个选项,选出符合文意的项。A项certain“确定的”;B项unlikely“未必的,靠不住的,不太可能的”;C项likely“很可能的;合适的;有希望的”;D项uncertain“不确定的,反常的”。将各个选项代入,只有D项符合文意。所以选D。
