问题 Scientists reported last month on a sign of relative solar________: the solar wind, a rush of charged particles continually spewed from the sun at a ml miles an hour, had diminished to it lowest level in 50 years.
A. quiescence
B. isolation
C. remoteness
D. calm
E. turbulence
F. instability
选项
答案A,D
解析 同义重复题。逻辑连接标志为冒号，表示前后同义重复。冒号前说报告显示solar有什么样的迹象，冒号后说太阳风降低到了50年来的最低水平(solar wind diminished to its lowest level)。因此空格应表达“减小到最低水平”的含义，A项quiescence(静止)和D项calm(平静)最符合。这两个选项的英文解释中都有一个共同的含义即inactivity。有同学会误选turbulence和instability选项。注意题目是问上个月报告显示的太阳风有怎样的迹象，空格直接对应diminished to its lowest level，对于太阳风而言， “降到最低水平”自然是对应calm和quiescence。turbulence和instability不合适，题目并不是问从强到弱的波动过程。
