下面是英语六级词语辨析，育路教育网特别为您搜集整理，内容如下：
concerned，concerning
这两个词的词义并不相同，用法亦有异。
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）。请看下面的例句：
This agreement will be signed by the parties concemed.此协议将由各有关方面签署。
They called on all departments concemed 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。
下面是concerning的例句：
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。
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 concemed （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解作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。
