reproduction: implies an exact or close imitation of an existing thing: ~s from the museum’s furniture collection.  （imitate低劣模仿suggests the following of a model or a pattern, but may allow for some variation and may imply inferiority in the product可能和原件不同，暗指低劣，如imitate a poet's style模仿一位诗人的风格。但这里限定了"exact and close准确逼真"，已不是一般的imitate）


duplicate: implies a double or counterpart exactly corresponding to an original in all significant respects: make a ~ of the key.  （double成对的两部分组成的having or made of two things or parts that are equal or similar，如double doors双扇门/a double-page advertisement双页广告/'Otter' is spelt with a double t otter一词中有两个t/my extension is two four double 0 (2400)我分机号是2400；还表示极相似的对应物refers to a person or thing that looks exactly like another，如she's the double of her mother她和她母亲长得一模一样）

copy: applies especially to one of a number of things reproduced mechanically: ~ies of the report were issued to all.  （copy拷贝复制suggests the duplicating of an original as closely as possible尽可能逼真，如copied the painting and sold the fake as an original仿制油画以真品出售）


facsimile: suggests a close reproduction in the same materials that may differ in scale: a ~ of an illuminated medieval manuscript. 这个词容易写错，先记住发音，利用英文"能读就能写"的特点把facsi记住，结尾英里mile，这样就不会错了，另一写法是Fax传真


replica: emphasizes the closeness of likeness and is specifically used of a reproduction made exactly like the original: ~s of the ships used by Columbus.


reproduction复制: 指仿制得准确逼真的复制品，duplicate复制: 指复制出对等物对应物，各主要方面相同，copy复制拷贝: 指机械复制品，facsimile复制传真: 表示同等材质，不同比例的复制品，replica复制: 强调准确逼真


记忆方法: 1）首字母RDCFR非常地软弱，把原件想成强硬<==复制

         2）复制的意思是和原件相似mean something that closely resembles a thing previously made, produced, or written.
