题目内容
3.Aside from the potential health hazards(危害)_____ can cause to the people,nuclear energy can also cause thousand deaths when its reactor explode.( )A. | which | B. | that | C. | what | D. | it |
分析 核能源除了能给人类造成潜在的健康危害之外,当核反应堆爆炸时它还会造成成千上万人的死亡.
解答 答案:D.
本句中_____ can cause to the people为定语从句,修饰先行词health hazards,cause后面缺少宾语,由that或者which来引导,可省略;结合选项,只有it在此处指代的是nuclear energy;故选D.
点评 定语从句是用来修饰名词的形容词性从句,相当于一个形容词.连接定语从句的引导词分为关系代词和关系副词,关系代词在从句中要作主语或宾语;关系副词在从句中作状语.这也是选择关系词的一个判断方法.
