Robin’s words were not without emotion: they retained their level tone only by careful ______ imminent extremes.
【正确答案】
A
【答案解析】- 方程等号:by引导方式状语,前后句意同义重复。
- 强词和对应:根据题意,Robin的话不是(not)没有(without)情绪,它们保持平稳的语调。空格和retained their level tone根据by构成同义重复,体现在突发的极端中谨慎地“保持”。equipoise between在…之间保持平衡,embrace of接受…,oscillation between在…之间摇摆,limitation to对…的限制,subjection to屈服于…。答案选A。
