Deflect 使偏斜，转向

原文：The possibility that mass extinctions may recur periodically has given rise to such hypotheses as that of a companion star with a long-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth as meteors and causing widespread devastation upon impact.对于周期性出现大规模物种灭绝的可能性，引发了这样的假设：一颗具有长周期轨道的伴星体使其他天体从正常轨道偏离，导致其中一些天体变成流星掉落到地球，撞击时造成大范围破坏。

强化记忆：Never let a little problem deflect you. 决不要因一点小问题就半途而废。

This special metal shield will deflect a bullet from its course. 这种特殊的金属盾将使子弹改变方向。

Devastate 毁坏，毁灭
