If giant x-ray flares churn circumstellar disks enough to keep newborn planets, such as Earth once was, from spiraling into their suns, it would be an ironic twist on our conception of x-ray flares as________.
A. dangerous
B. predictable
C. ancient
D. ephemeral
E. perilous
F. foreseeable
选项
答案
A,E
解析
-方程等号:ironic讽刺的,反义重复。
-强词和对应:ironic出现,句意取反,前面说X射线耀斑可以阻止新的行星旋转进入到它们的恒星里,说明X射线会保护新的星球,根据ironic反义重复,空格应填入“保护”的反义词。选项里有两组同义词,第一组是dangerous与perilous危险的,第二组是predictable与foreseeable可以预测的,所以答案选择AE。其他选项,ancient古老的,ephemeral短暂的。
