问题 Although supernovas are among the most (i)______ of cosmic events, these stellar explosions are often hard to (ii)______, either because they are enormously far away or because they are dimmed by intervening dust and gas clouds.

选项 A、remote…observe
B、luminous…detect
C、predictable…foresee
D、ancient…determine
E、violent…disregard

答案 B

解析 空格(ii):
- 方程等号:because表示因果,同义重复。
- 强词和对应:they指代explosions,根据题意,因为超新星的爆炸是非常遥远的,或者因为超新星的爆炸由于介入的灰尘和气体云而变得昏暗。因此hard to+空格(ii)和dimmed根据because取同,填一个正向词。observe观测,detect觉察,foresee预知,determine决定,disregard忽视。选项A、B和D合适。
空格(i):
-方程等号:although尽管,句内取反。
- 强词和对应:主句部分说,超新星的爆炸是难以观测的,因此空格(i)和难以观测根据although取反,体现超新星是最“容易观测”的天文现象。remote遥远的(错),luminous明亮的(对),predictable可预测的(错),ancient古老的(错),violent剧烈的(对)。综合空格(ii),答案选B。
