我认为furthermore是英语中一个非常有用的递进关系词汇，它可以用来连接两个或多个句子，使文章更加连贯和流畅。
1. 用于列举：Furthermore, we offer a free trial period and a money-back guarantee.
2. 用于补充：The new system is faster, more efficient, and furthermore, it is more reliable.
3. 用于强调：The company is committed to reducing its carbon footprint. Furthermore, it has implemented a recycling program.
