的说法，意思是“我的荣幸之至”。你可以把它想成是Ithasbeenmypleasuretohelpyou（能够帮助你是我的荣幸。）的省略结果。这个句子还能有如下的用法：ImgladtomeetyouThepleasureisallmine“（很高兴认识你。哪里，我才是呢。）Couldyouhelpmeforaminute？Mypleasure“（你可以帮我一下吗？我很乐意,（1）根据句意，用pleasant,pleased或pleasure填空。,1.Ihada_time.2.Hewillbe_tohelpyou.3.Readinggivesmegreat_.4.Itgivesme_toseeyoulookinghappy.5.Wespenta_dayinthecountry.,pleasant,pleased,pleasure,pleasure,pleasant,Choosethebestanswer,（2）Ithinkitisimpossibletomakeeveryone_.A.pleaseB.pleasedC.pleasantD.pleasure,B,用所给词的适当形式补全句子1.-Whenthetelephone?-Ithinkitin1876.(invent)2.-W
