   ## Refactor routes to a _Routing Module_
 
+  ## 重构路由为一个**路由模块**
+
   Almost 20 lines of `AppModule` are devoted to configuring four routes. 
   Most application have many more routes and they [add guard services](../guide/router.html#guards) 
   to protect against unwanted or unauthorized navigations. 
   Routing considerations could quickly dominate this module and obscure its primary purpose which is to 
   establish key facts about the entire app for the Angular compiler.
 
+  `AppModule`中有将近20行代码是用来配置四个路由的。
+  绝大多数应用有更多路由，并且它们还有[守卫服务](../guide/router.html#guards)来保护不希望或未授权的导航。
+  路由的配置可能迅速占领这个模块，并掩盖其主要目的，即为Angular编译器设置整个应用的关键配置。
+
   We should refactor the routing configuration into its own class.
   What kind of class? 
   The current `RouterModule.forRoot()` produces an Angular `ModuleWithProviders` which suggests that a
   class dedicated to routing should be some kind of module.
   It should be a [_Routing Module_](../guide/router.htm#routing-module).
 
+  我们应该重构路由配置到它自己的类。
+  什么样的类呢？
+  当前的`RouterModule.forRoot()`产生一个Angular `ModuleWithProviders`，所以这个路由类应该是一种模块类。
+  它应该是一个[**路由模块**](../guide/router.htm#routing-module)。
+
   By convention the name of a _Routing Module_ contains the word "Routing" and 
   aligns with the name of the module that declares the components navigated to".
+
+  按约定，**路由模块**的名字应该包含“Routing”，并与导航到的组件所在的模块的名称看齐。
   
   Create an `app-routing.module.ts` file as a sibling to `app.module.ts`. Give it the following contents extracted from the `AppModule` class:
 
+  在`app.module.ts`所在目录创建`app-routing.module.ts`文件。将下面从`AppModule`类提取出来的代码拷贝进去：

   Noteworthy points, typical of _Routing Modules_:
+  
+  典型**路由模块**值得注意的有：
+  
   * Pull the routes into a variable. You might export it in future and it clarifies the _Routing Module_ pattern.
 
+  * 将路由抽出到一个变量中。你可能将来会导出它。而且它让**路由模块**模式更加明确。
+
   * Add `RouterModule.forRoot(routes)` to `imports`.
+
+  * 添加`RouterModule.forRoot(routes)`到`imports`.
     
   * Add `RouterModule` to `exports` so that the components in the companion module have access to Router declarables 
   such as `RouterLink` and `RouterOutlet`.
+
+  * 添加`RouterModule`到`exports`，这样关联模块的组件可以访问路由的声明，比如`RouterLink`和`RouterOutlet`。
   
   * No `declarations`!  Declarations are the responsibility of the companion module.
 
+  * 无`Declarations`！声明是关联模块的任务。
+
   * Add module `providers` for guard services if you have them; there are none in this example.
 
+  * 如果你有守卫服务，添加模块`providers`；本例子无守卫服务。
