positive.code:     [`BrowserModule`](../latest/api/platform-browser/index/BrowserModule-class.html)
      from `@angular/platform-browser` to the `imports` array.
      
      由于QuickStart是一个运行在浏览器中的Web应用，所以根模块需要从`@angular/platform-browser`中导入[`BrowserModule`](../latest/api/platform-browser/index/BrowserModule-class.html)并添加到`imports`数组中。
  
      This is the smallest amount of Angular that is needed for a minimal application to run in the
      browser.
      
      这是要让一个最小的应用在浏览器中运行时，对Angular的最低需求。
  
      The QuickStart application doesn't do anything else, so you don't need any other modules. In a real
      application, you'd likely import [`FormsModule`](../latest/api/forms/index/FormsModule-class
  
negative.code:   
    This first application doesn't do much. It's basically "Hello, World" for Angular.
  
    第一个应用没做什么，它只是Angular的"Hello, World"而已。
  
    You wrote a little Angular component, created a simple `index.html`, and launched with a
    static file server.
  
    我们写了很小的Angular组件，创建了简单的`index.html`，并且启动了静态文件服务器。
