such as相当于for example，后面接一部分列举对象；而etc.用于句尾，相当于and so on，中文里也常在句尾加个“等”，不过在中文里很多时候即便把所有对象列举出来，后面仍然习惯性地加一个“等”字。
such as和etc.这两个词不能同时使用：
错误 Studies of methodology and process of implementing remanufacturing mainly focus on durable products such as automobile motors, printers, etc.
正确 Studies of methodology and process of implementing remanufacturing mainly focus on durable products such as automobile motors and printers.
etc.在句尾时不用再加句号了：
错误 The patients were treated with chymotrypsin, gentamicin, dexamethasone, etc..
正确 The patients were treated with chymotrypsin, gentamicin, dexamethasone, etc.
etc.前不用加and：
错误 The patients were treated with chymotrypsin, gentamicin, dexamethasone, and etc.
正确 The patients were treated with chymotrypsin, gentamicin, dexamethasone, etc.
such as后面只能跟部分列举对象，而不应该是全部对象。
错误 Compared with traditional industry, Micro-electronic fabrication has three characteristics such as high complexity, high precision and high automation.
正确 Compared with traditional industry, Micro-electronic fabrication has three characteristics: high complexity, high precision and high automation.
including和such as的使用方法类似，后面只能跟部分列举对象，而不是全部对象。
