如有几道题,请加上题号.
第1题:考短语动词,选B.knock out 摧毁.很容易上当误选 knock down,这是受中文思维“击落”的影响所致.教训:不要用中文硬译英语的短语动词.
第2题:选A,relative 相对的.这道题没有复杂的语法,答错的原因是不理解题意,即不了解 relative 的词义.翻译:你以为你穷,但是看看那些真正贫穷国家里的人吧.穷完全是相对而言的!
第3题:考短语动词,选D,lay down 放弃; 牺牲,例句:
The martyr laid down his life for the cause of national independence.
这位烈士是为了民族独立的事业而献身的.(源自《金山词霸2009牛津版》)
第4题,考状语从句,选C,when,题意:当你把精力都“奉献”于玩电脑游戏的时候,你还能指望学会任何知识吗?(这里的devote显然是讽刺用法.)
