-Finally, you can also restrict the type of the accepted event to a subtype of
the initial event type (here `Event`)
-via the `pattern.subtype(subClass)` method.
+最后，你可以通过`pattern.subtype(subClass)`方法限制接受的事件类型是初始事件的子类型。

-**Combining Conditions:** As shown above, you can combine the `subtype`
condition with additional conditions. This holds for every condition. You can
arbitrarily combine conditions by sequentially calling `where()`. The final
result will be the logical **AND** of the results of the individual conditions.
To combine conditions using **OR**, you can use the `or()` method, as shown
below.
+**组合条件：** 如上所示，你可以把`subtype`条件和其他的条件结合起来使用。这适用于任何条件，你可以通过依次调用`where()`来组合条件。
+最终的结果是是每个单一条件的结果的逻辑**AND**。如果想使用**OR**来组合条件，你可以使用像下面这样使用`or()`方法。
