问题 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。
