Recently a survey ______ prices of the same goods in two different supermarkets has caused heated debate among citizens.
A. compared
B. comparing
C. compares
D. being compared
题目解答
答案
B. comparing
解析
本题考查非谓语动词的用法,核心在于判断动词与逻辑主语之间的关系。句子主干为"a survey has caused heated debate",空处需填入的动词短语作定语修饰survey。关键点在于:
- 逻辑主语与动词的关系:survey与compare是主动关系,即调查本身“进行比较”;
- 非谓语形式选择:需用现在分词表示主动进行的动作,且作定语时无需被动形式。
选项分析
- A. compared:过去分词表示被动完成,但survey与compare是主动关系,排除;
- B. comparing:现在分词表示主动动作,正确修饰survey;
- C. compares:第三人称单数形式需作谓语,但句中已有谓语has caused,排除;
- D. being compared:现在分词被动形式,与主动意义矛盾,排除。
句法功能
现在分词短语comparing prices作定语,修饰survey,说明调查的目的或内容,即“一项比较商品价格的调查”。
