     The `DebugElement.query(predicate)` and `DebugElement.queryAll(predicate)` methods take a
     predicate that filters the source element's subtree for matching `DebugElement`.
   
  +  `DebugElement.query(predicate)`和`DebugElement.queryAll(predicate)`方法接受一个条件方法，
  +  它过滤源元素的子树，返回匹配的`DebugElement`。
  +
     The predicate is any method that takes a `DebugElement` and returns a _truthy_ value.
     The following example finds all `DebugElements` with a reference to a template local variable named "content":
  +
  +  这个条件方法是任何接受一个`DebugElement`并返回真值的方法。

     * `By.all` - return all elements

     * `By.css(selector)` - return elements with matching CSS selectors.
  -  * `By.directive(directive)` - return elements that Angular matched to an instance of the directive class. 
  +
  +  * `By.css(selector)` - 返回符合CSS选择器的元素。
  +
  +  * `By.directive(directive)` - return elements that Angular matched to an instance of the directive class.
