题目内容
20."Genius"is a complicated concept, many different factors.( )| A. | involved | B. | involving | C. | toinvolve | D. | beinginvolved |
分析 "天才"是一个复杂的概念,涉及了许多不同的因素.
解答 答案:B根据"is"和"involve"两个动作之间无连接词出现可知,此处应用非谓语动词做状语,因为concept与involve是主动关系,用现在分词.现在分词短语作非限制性定语.此处相当于一个非限制性定语从句which involves many different factors.将其改成短语的形式就是现在分词短语involving many different factors.选项A过去分词和选项D现在分词的被动式,与句子主语的关系是被动的,所以排除选项A和D,而这个概念现在本身就涉及,所以排除表示将来的C,故选B.
点评 本题考查非谓语动词的现在分词.非谓语作定语要考虑动词和所修饰的名词之间的关系,是主动用现在分词,被动用过去分词,不要混淆现在分词和过去分词的用法而选择错误.
