1.Dinsaurs, fr example, died ut abut 65 millin years ag.例如，恐龙大约在6500万年前灭绝。fr example”的意思是“例如；比如”，用于在陈述一个观点或概念后，给出具体的例子来进一步解释说明。它后面可以接句子，也可以接短语。Yu shuld eat mre fruits, fr example, apples and bananas are gd fr yur health.（你应该多吃水果，例如，苹果和香蕉对你的健康有好处。）
such as”意思是“例如；像……这样”，主要用于列举同类事物中的几个例子，后面通常直接接名词、名词短语或动名词。 Fruits such as apples, ranges and grapes are my favrites.（像苹果、橙子和葡萄这样的水果是我的最爱。）
记忆方法fr example 可以记住“fr（为了）+ example（例子）”，表示为了说明某个观点而给出的例子，而且这个例子可以是比较复杂的句子结构。such as 理解为“such（这样的）+ as（像……）”，强调列举的是同一类事物中像这样的几个代表，后面一般直接跟简单的名词性成分。
