英语六级-完形语法关键句343. Trademarks are words, names, or symbols t

343. Trademarks are words, names, or symbols that identify the manufacturer of a product and distinguish it from similar goods of others.

译文　商标是用于识别产品生产商并且使之区别于其他类似产品的一些文字、名称或符号。

点睛　本句的主干是Trademarks are words, names, or symbols...。后面的that引导的是定语从句，具体说明商标所使用的品牌名称、符号等。句中identify意为“识别，确定，辨别”，而distinguish sth. from sth.意为“区分……和……”。
