-# 8.5 小结
-这一章我们介绍了目前流行的几种主要的网络应用开发方式，第一小节介绍了网络编程中的基础:Socket编程，因为现在网络正在朝云的方向快速进化，作为这一技术演进的基石的的socket知识，作为开发者的你，是必须要掌握的。第二小节介绍了正愈发流行的HTML5中一个重要的特性WebSocket，通过它,服务器可以实现主动的push消息，以简化以前ajax轮询的模式。第三小节介绍了REST编写模式，这种模式特别适合来开发网络应用API，目前移动应用的快速发展，我觉得将来会是一个潮流。第四小节介绍了Go实现的RPC相关知识，对于上面四种开发方式，Go都已经提供了良好的支持，net包及其子包,是所有涉及到网络编程的工具的所在地。如果你想更加深入的了解相关实现细节，可以尝试阅读这个包下面的源码。

+# 8.5 Summary
+
+In this chapter, I introduced you to several mainstream web application development models. In section 8.1, I described the basics of network programming sockets. Because of the rapid evolution of network technology and infrastructure, and given that the Socket is the cornerstone of these changes, you must master the concepts behind socket programming in order to be a competent web developer. In section 8.2, I described HTML5 WebSockets which support full-duplex communications between client and server and eliminate the need for polling with AJAX. In section 8.3, we implemented a simple application using the REST architecture, which is particularly suitable for the development of network APIs; due to the rapid rise of mobile applications, I believe that RESTful APIs will be an ongoing trend. In section 8.4, we learned about Go RPCs. 
+
+Go provides excellent support for the four kinds of development methods mentioned above. Note that the `net` package and its sub-packages is the place where Go's network programming tools Go reside. If you want a more in-depth understanding of the relevant implementation details, you should try reading the source code of those packages.
