请你帮我看看委托书

供参考***(name of company) hereby authorizes Mr. YYY, holder of passport number ZZZZ, as its representative to discuss the matters concerning Recycling Material in ***.注：I,***(the name of my company)这结构是同位语但’我‘显然就不可能是’公司‘所以建议真接用 *** hereby 如果‘I’是代表公司作出授权的人可以改为I，on behalf of ***, hereby authorize Mr. YYY, holder of passport number ZZZZ, as its representative to discuss the matters concerning Recycling Material in ***.而authorizes 改为 authorizeauthorized 是过去时在这里宜用’现在时‘如果采用*** hereby authorizes的结构as the representative of ***便可以省略至 its representative一点意见Mr YYY 若然公司员工这委任信大致上可以接受如果是外界人士内容可以有补充之处例如说明有效日期以及在什麼地方可以作为代表 原问题：《帮我检查下委托书的语法和词汇哈~》
