-## 错误处理
+## Error Handle

+### Extend Error Type
 
-### 扩展错误类型
+You can extend error type in your project depending on the practical requirement. such as adding the specific `600` error, and you can do as the following steps.
 
-项目里可以根据需要扩展错误类型，假如添加一个项目特有的错误 `600`，那么可以通过下面步骤进行：
+##### 1. add _600Action
 
-##### 1、添加 _600Action
+Add the following codes into `src/common/controller/error.js` file in the appropriate place.
 
-在 `src/common/controller/error.js` 文件中，合适的位置添加如下的代码：
 
 ```js
   _600Action(){
     return this.displayErrorPage(600);
   }
 ```
 
-##### 2、添加错误页面
+##### 2. Add Error Page
 
-添加文件 `view/common/error_600.html`，并在文件里添加显示的错误内容。
+Add the file `view/common/error_600.html`, and write the corresponding error information into it.
 
-##### 3、显示错误页面
+##### 3. Show Error Page
 
-添加完错误后，需要在对应地方调用显示错误才能让用户看到，可以通过 `think.statusAction` 方法实现。如：
+After added the error, you need to call it correspondingly in order to show it for users. It can be achieved by `think.statusAction` method. eg.
 
 ```js
 export default class extends think.controller.base {
   indexAction(){
     if(someError){
-      return think.statusAction(600, this.http); //显示 600 错误，需要将 http 对象传递进去
+      return think.statusAction(600, this.http); //show 600 error, need to pass http object
     }
   }
 }
 ```
 
 
-### 修改错误页面样式
-
-修改错误页面样式，只需要修改对应的模版文件即可，如：修改 `404` 错误则修改模版文件 `view/common/error_404.html`。
+### Modify Error Page Style
 
+In order to modify the error page style, you just need to modify the corresponding template file. Eg. edit the template file `view/common/error_404.html` to modify `404` error page style.
