   This library is also useful to you during early development before you have a server to talk to.
 
+  许多例子使用了`angular-in-memory-web-api`来模拟远程服务器。
+  这个库在你拥有服务器之前的早期开发阶段也很有用。
+
   The package name was changed from "angular2-in-memory-web-api" which is still frozen-in-time on npm.
   The new "angular-in-memory-web-api" has new features. 
   <a href="https://github.com/angular/in-memory-web-api/blob/master/README.md" target="_blank">Read about them on github</a>.

   [StyleGuide](style-guide.html) explains our recommended conventions for Angular modules (NgModule).
+
+  [StyleGuide](style-guide.html)解释了我们为Angular模块（NgModule）而推荐的约定。

   Barrels now are far less useful and have been removed from the style guide;
   they remain valuable but are not a matter of Angular style.
   We also relaxed the rule that discouraged use of the `@Component.host` property.
 
+  现在，封装桶不再那么重要，风格指南已经移除了它们。
+  它们仍然很有价值，但是它们与Angular风格无关。
+  我们同时对**不推荐使用`@Component.host`属性**的规则有所放宽。

   ## _moduleId: module.id_ everywhere (2016-09-25)
 
+  ## moduleId：到处添加module.id(2016-09-25)

   Sample components that get their templates or styles with `templateUrl` or `styleUrls`
   have been converted to _module-relative_ URLs.
   We added the `moduleId: module.id` property-and-value to their `@Component` metadata.
+
+  在所有使用`templateUrl`或者`styleUrls`来获取模板或样式的例子组件都被转换为**相对模块**的URL。

   modules with SystemJS as the samples currently do.
 
+  当应用像例子当前使用的方法一样 - 使用SystemJS加载模块时，本更新是AoT编译器的前提条件。
