involve 和 concern 都作涉及的意思时有什么区别？
推荐回答（3个）
一、词义辨析不一样
1、involve v. 包含，涉及
〔辨析〕对必不可少的要素的包括和对必要条件的涉及
〔例证〕New employees need to know what the job will involve.
新员工们需要知道这份工作包括什么。
2、concern v. 影响，涉及
〔辨析〕指人〔物，事物〕之间的联系与影响。
〔例证〕Matters of pollution and the environment concern us all.
污染和环境等问题涉及我们大家。
二、词义广泛性不一样
1、involve
英 [ɪn'vɒlv] 美 [ɪn'vɑlv]
vt. 包含；牵涉；使陷于；潜心于
2、concern
英 [kən'sɜːn] 美 [kən'sɝn]
vt. 涉及，关系到；使担心
n. 关系；关心；关心的事；忧虑
三、变形词不一样
1、involve
第三人称单数： involves 现在分词： involving 过去式： involved 过去分词： involved
2、concern
第三人称单数： concerns 复数： concerns 现在分词： concerning 过去式： concerned 过去分词： concerned
只单纯指有关、涉及这一层关系上，involve和concern区别不大，比如the question involved和the question concerned其实很接近。如果真要说有区别的话，Involve会有“在问题内部”“是问题的一部分”这一层意思，concern比较侧重单纯的关联性，可以是横向的、平等的关联，不一定是纵向的、子集的关系。
involve （ 动词）. 包括, 潜心于, 使陷于；concern 作为名词：关心、忧虑作为动词：涉及、关系到
