举例的连接词，它一般用来列举同类人或物中的几个例子，插在被列举的例子和前面的名词之间，as后没有逗号。如：1. He has been to many countries, such as America, Japan and Germany.他去过很多国家，比如美国、日本和德国。2.He can speak three foreign languages, namely Chinese, English and French.他能说三门外语，即汉语、英语和法语。三、take...for example是一个固定用法，意思是以......为例，例如：1.Take it for example, please. 请以此为例。2.Take his method for example, it saves time.照着他的方法去做，节省时间。3.Take apples for example, it could help preventing heart attack.拿苹果来说，吃苹果可以预防心脏病。四、for instance的意思是：例如,譬如,比如,比方说；instance和example是同义词，它们都表示“例子”的意思。因此 for instance 就等于for example，都是“举例而言”的意思。for instance可以前置或者后置。1. Take general elections for instance.2. We made many improvements to our house; for instance, we painted the walls and bought new carpet.）
