+`SegmentedControl` includes at least two segments, it is used to display diffrent views and recommended by `iOS`.
 
-由至少 2 个分段控件组成，用作显示不同视图的显示；是 iOS 的推荐组件。

-### 规则
-- 和 Tabs 功能相似，尽可能避免一个页面中同时出现这两个组件。
-- 可以搭配 NavBar 一起使用，用于显示多个视图，分段数一般为 2 个。
-- 单独放置一行时，分段数最多为 5 个；文案需要精简，一般 2-4 个字。
-- 尽可能保持文案长度一致。
+### Rule
+- It is similar to the functionality used for `Tabs`, so avoid to use them at same page as much as possible.
+- You can use `SegmentedControl` with `NavBar` to display mutiple views.
+- Generally there should be no more than 5 segments in one line, each segment has 2-4 words and needs simplified texts.
+- Keep the length of the text consistent as much as possible.
