concerned和concerning用法辨析

    concerned，concerning这两个词的词义并不相同，用法亦有异。

一、Concerned是分词形容词，其意为“有关的”（involved）; concerning是由分词转换而成的介词，其意为“关于”（relating to）。例句：

• This agreement will be signed by the parties concerned．此协议将由各有关方面签署。
• They called on all departments concerned to take prompt steps to promote the development of light industry．他们要求各有关部门迅速采取措施，促进轻工业发展。

　　由例句可见，concerned用作形容词解作“有关的”时，是后置定语，大都放在它所修饰的名词之后。但在verb“to be”之后而同样解作“关于”时，则要用be concerned with的形式，如：

　　This book is concerned with English usage．此书是与英语惯用法有关。

　　值得注意的是，concerned（亦可表示动词之意）也可解作“关心”、“担心”解，与之搭配的介词为at、about或，用作此意时，concerned也是形容词。例：

• He was deeply concerned at the news．听到这个消息时，他深为担忧。
• We are all concerned about the pollution of the environment here．对这里的环境爱到污染，我们都感到不安。
• Parents are naturally conerned for their children's safety．　　父母自然关心他们儿女的安全。

二、Concerning 词义为“关于，涉及”，用英语通常可以解释为about.

• This is a proposal concerning the construction of the new airport．这是关于兴建新机场的一项建议。
• If you have any information concerning the recent incident at the station,please contact the police. 如果你有和最近这次车站的暴力事件相关的信息，请和警察取得联系。
• Yesterday we wrote him a letter concerning the business arrangement．昨天我们就业务安排问题写了一封信给他。

　　在个别场合下，concerned with可以和concerning互换使用，原因是如果用“concerned with”可以看作是从句which are concerned with中的which are 省略了。例如：

　　We had several disputes concerning/（which are）concerned with this matter．关于此事，我们曾争论过数次。

　　请注意，下列语句的区别：

• They were concerned（worried）about the matter．他们为此事而担忧。
• They were concerned（implicated）in the matter．他们参与此事。= They were involved in the matter. 他们参与此事。
• They were concerned （connected）with the matter．他们与此事有关。

　　此外，作为特定词组，as far as I am concerned解作in my opinion；as far as sth is concerned时，可以理解为concerning sth/ talking about sth.例：

• As far as I'm concerned，this plan is impractical．依我来看，这个计划不切实际。
• As far as funding is concerned，some banks have agreed to provide loans．关于资金方面，一些银行同意提供贷款。
