题目内容
【题目】The first thing __________ I did was to see if there were any products __________ might help me, but there only seemed to be powders __________ to kill snakes.
A. that; /; designed B. which; that; designed
C. /; that; designed D. /; which; design
【答案】C
【解析】句意:我做的第一件事是看看是否有能帮助我的产品,但似乎只有用来杀死蛇的粉末。the first thing后是定语从句,关系词that在从句中可以省略;名词product后是定语从句,关系词可用that或 which,又因关系词在从句中作主语,不能省略;动词design 与名词powders在逻辑上为被动关系,且动作已发生,故用过去分词短语作后置定语。
