   ## NEW: Samples re-structured with `src/` folder (2017-02-02)
+  
+  ## 新增：调整了范例程序的结构，移到了`src/`文件夹 (2017-02-02)
+  
   All documentation samples have been realigned with the default folder structure of the angular-cli.
   That's a step along the road to basing our sample in the angular-cli.
   But it's also good in its own right. 
   It helps clearly separate app code from setup and configuration files.
+  
+  所有的文档范例都已经向angular-cli的默认文件夹结构看齐了。
+  这是把范例迁移到angular-cli过程中的一步。
+  不过也不仅是为了迁移，它确实能帮我们把应用代码从环境代码和配置代码中分离出来。
 
   We've updated all samples with an `src/` folder at the project root.
   The former `app/` folder moves under `src/`. 
   Read about moving your existing project to this structure in

+  
+  我们已经把所有范例改成了使用项目根目录下的`src/`文件夹。
+  也就是把以前的`app/`文件夹移到了`src/`文件夹下面。
+  要了解如何对你的现有工程进行这种迁移，请参阅<a href="https://github.com/angular/quickstart#updating-to-a-newer-version-of-the-quickstart-repo" target="_blank" target="把范例中的应用迁移到src文件夹">QuickStart中的迁移指南</a>。

   * `index.html`, `styles.css` and `tsconfig.json` moved inside `src/`.
+  
+      把`index.html`、`styles.css`和`tsconfig.json`移到`src/`中。
+  
   * `systemjs.config.js` now imports `main.js` instead of `app`.
+  
+      `systemjs.config.js`现在要导入`main.js`而不是`app`。
+  
   * Added `lite-server` configuration (`bs-config.json`) to serve `src/`.
+  
+      新增了一个`lite-server`配置(`bs-config.json`)以便在`src/`下启动开发服务器。
 
   ## NEW: Reactive Forms guide (2017-01-31)
+  
+  ## 新增：响应式（Reactive）表单指南 (2017-01-31)
+  
   The new [**Reactive Forms**](reactive-forms.html) guide explains how and why to build a "reactive form".
   "Reactive Forms" are the code-based counterpart to the declarative "Template Driven" forms approach
   introduced in the [Forms](forms.html) guide.
   Check it out before you decide how to add forms to your app. 
   Remember also that you can use both techniques in the same app, 
   choosing the approach that best fits each scenario.
+  
+  新的[**响应式表单**](reactive-forms.html)指南解释了如何以及何时构建“响应式表单”。
+  “响应式表单”是基于代码的表单构建方式，与[表单](forms.html)中介绍的声明“模板驱动”表单的方法相对。
+  在你决定如何往应用中添加表单之前，建议先读读那一章。
+  同时，别忘了你可以在同一个应用中同时使用这两种技术，根据场景来选择最合适的方法。
 
   ## NEW: Deployment guide (2017-01-30)
+  
+  ## 新增：部署指南 (2017-01-30)

   Linked to these plunkers in [Testing](testing.html#live-examples) and [Setup anatomy](setup-systemjs-anatomy) guides.
+  
+  添加了两个plunker例子，每个都测试一个简单的组件，以便你可以自己在plunker中写组件测试：<live-example name="setup" plnkr="quickstart-specs">一个</live-example>用于测试快速起步中的`AppComponent`，<live-example name="testing" plnkr="banner-specs">另一个</live-example>用于测试“测试”章节的`BannerComponent`。
