我喜欢选文中的两段话要表达的感情并不相同作者是用什么连接这两段的？

作者在两段话之间使用的连接手法主要有以下几种:

1. 转折连接。使用转折conjunction或者副词,如but、however、though、nevertheless、nonetheless等,表明两段话之间的转折或对比关系。例如:I like dogs. They are loyal and friendly. However, they require a lot of care and responsibility.

2. 顺承连接。使用顺承conjunction, 如and、also等,表达两段话之间的顺承或补充关系。例如:I enjoy reading books. And I also like to travel to experience different cultures.

3. 因果连接。使用因为conjunction,如 because、since、as等,表达前段为原因,后段为结果。例如:I have to study hard tonight because I have two tests tomorrow.

4. 举例连接。使用例如副词或者短语,如for example、for instance、such as等,表达后段为前段的举例详细内容。例如:There are many ways to relax such as reading, exercising, meditation or yoga.

5. 总结连接。使用总结conjunction,如 in conclusion、in summary、to sum up等,表达后段为前段的总结或重申。例如:The new product has many advanced features. In summary, it provides efficiency, convenience and state-of-the-art technology.

6. 递进连接。使用递进conjunction,如 moreover、furthermore、in addition等,表达两段话在逻辑上或论点上有递进关系。例如:Technology improves living standards. Furthermore, it enhances connectivity and sharing of knowledge. 

以上就是作者在两段话之间常使用的连接手法,通过转折、顺承、因果、举例、总结或递进等连接手法,来表达两段话间的逻辑关系,使全文思路清晰连贯。希望对您有所帮助!
