考博英语每日一练（12.24）参考答案

1.B

【句意】电视使我们几乎能在事情发生的同一时刻看到事情的发生。

【解析】语法结构——when（有时可以省略）引导定语从句。由空格前的先行词“the exact moment同一时刻”表示时间可直接排除使用关系代词which的A项“which they are happening”和C项“which they happen”，也由此知这里应该使用现在进行时态，故B项“they are happening”正确。

2.D

【句意】几次核灾难之后，一场关于核能安全的争论激烈起来。

【解析】名词词义辨析。quarrel“争吵；争端”；suspicion“怀疑；猜疑”；verdict“裁决；结论”；controversy“（公开的）争论”。由句中关键词“After several nuclear disasters几次核灾难之后”的对应知“（公开的）争论”符合语境，故D项正确。
