1. His power was seriously ______ by a succession of crises, and when he died, a bitter power struggle ______.
A. weakened, was ensued B. eroded, ensued
C. damaged, followed D. reduced, occurred
B 【句意】一连串的危机严重削弱了他的权力，在他死后一场激励的权力争夺随即发生。
【解析】动词词义辨析。由句中关键词“His power was seriously………严重削弱了他的权力”与“and when he died, a bitter power struggle…在他死后一场激励的权力争夺……”的对应知第二空填“ensue(其动词过去式为ensued)随即发生”更符合语境，故B项正确。weaken“削弱;(使)虚弱”;erode“削弱;侵蚀”;damage“伤害;毁坏”;follow“跟随;接着……发生”;reduce“减少”;occur(其动词过去式为occurred)“发生”。
2. Wealthy people’s children do not necessarily ______ better because they are ______ spoiled.
A. fair, inclined to be B. fair, bound to be
C. fare, prone to be D. perform, destined to be
C 【句意】富人的孩子并不一定会进行得更好，因为他们容易被宠坏。
【解析】动词词义辨析。由句中关键词“Wealthy people’s children do not necessarily…富人的孩子并不一定会……”的对应可直接排除第一个空使用“fair合理的;公平的”的A项与B项;再由D项中的“destined to be 注定会”的说法“太过绝对”可知C项正确。fare“进展;进行”;inclined to be“倾向于”;bound to be“一定会”;prone to be“容易”。

【解析】形容词词义辨析。afflictive“难受的;苦恼的”;authoritative“有权威的;命令式的”;obvious“明显的;显著的”;explicit“明确的;清楚的;详述的”。由句中关键词“so as to make every student understand ...以便让每个学生都明白……”可推知“明确的”符合，由此知D项正确。
