关于“compare with”在句首的用法,综合权威资料整理如下:
一、基本结构与用法
过去分词短语作状语 当“compare”与逻辑主语存在被动关系时,需使用过去分词短语作状语,结构为:
$$\text{逻辑主语} + \text{have/has been compared with} + \text{宾语}$$
例如:
$$This project has been compared with previous initiatives to assess its effectiveness.$$
在此结构中,"has been compared with"可置于句首,省略主语和be动词。
省略规则
若逻辑主语与主句主语相同,且be动词可省略,则"compared with"可直接置于句首。例如:
$$The new policy is more efficient compared with the old one.$$
省略后为:
$$The new policy is more efficient with the old one. 但需注意,这种省略仅适用于主动语态的主动形式。 二、使用要点 被动与主动的区分
- 被动含义:使用过去分词短语(如"has been compared with");
- 主动含义:使用现在分词短语(如"comparing with")。
常见搭配
- 与"as...as"结构结合使用:
$$This performance compares with/like that of the previous season."
- 与"be compared with"结构结合使用:
$$The company's growth rate has been compared with industry averages." 。
三、错误用法示例
主动语态误用过去分词:
$$The policy is compared with the old one (错误,应为被动结构);
介词误用:
$$Compare this design to the previous one (正确)而非"compare this design with the previous one"(后者为冗余表达)。
通过以上规则和要点,可灵活运用"compare with"在句首,确保语法正确且表达清晰。
