题目内容
1.Thomas Edison invented a lot,_______ his ideas on scientific experiments.( )A. | based | B. | to base | C. | basing | D. | base |
分析 将他的想法建立在了科学实验的基础上,Thomas Edison发明了许多东西.
解答 答案:C
分析句意可知,"_______ his ideas on scientific experiments"在句中作方式状语,此空缺处的动词base与主语Thomas Edison 构成主动关系,意为:Thomas Edison 将他的想法建立在科学实验的基础上,所以应使用现在分词形式;A.based 是过去分词,通常与主语构成被动关系,用在此处不合句意;B.to base是动词不定式,此处不能用作方式状语(动词不定式作方式状语时,通常只用于as if to do sth结构中),所以C不正确; D.动词base在句中作谓语,此处应该作状语,所以D不正确.故选C.
点评 本题考查了现在分词作方式状语的用法.做此类题时,首先应弄清该空缺处在句中所作的成分,然后判断它与主语是否构成主谓/主动关系;另外,还要注意总结现在分词与过去分词以及动词不定式的用法区别.
