-This hook is intended to be used for reading the value of asynchronous selectors. This hook will implicitly subscribe the component to the given state.
+此钩子可用于读取异步 selector 的值。为获取到指定状态值，此钩子将隐含地订阅对应组件。
 
-Unlike [`useRecoilState()`](/docs/api-reference/core/useRecoilState), this hook will not throw an `Error` or `Promise` when reading from an asynchronous selector (for the purpose of working alongside [React Suspense](https://reactjs.org/docs/concurrent-mode-suspense.html)). Instead, this hook returns a [`Loadable`](/docs/api-reference/core/Loadable) object for the value along with the setter callback.
+与 [`useRecoilState()`](/docs/api-reference/core/useRecoilState) 不同，当读取异步 selector 时，这个钩子不会抛出一个 `Error` 或`Promise` (为了能与 [React Suspense](https://reactjs.org/docs/concurrent-mode-suspense.html) 共存)。相反，这个钩子会返回一个 [`Loadable`](/docs/api-reference/core/Loadable) 对象的值以及 setter 回调。

 ```jsx
 function useRecoilStateLoadable<T>(state: RecoilState<T>): [Loadable<T>, (T | (T => T)) => void]
 ```
-- `state`: a writeable [`atom`](/docs/api-reference/core/atom) or [`selector`](/docs/api-reference/core/selector) that _may_ have some asynchronous operations. The status of the returned loadable will depend on the status of the provided state selector.
+- `state`: 一个可写的 [`atom`](/docs/api-reference/core/atom) 或 _可能_ 有一些异步操作的 [`selector`](/docs/api-reference/core/selector)。返回的 loadable 的状态将取决于所提供的状态 selector 的状态。
 
-Returns a [`Loadable`](/docs/api-reference/core/Loadable) for the current state with the interface:
+返回一个 [`Loadable`](/docs/api-reference/core/Loadable) 的当前状态与接口：
 
-- `state`: indicates the status of the selector. Possible values are `'hasValue'`, `'hasError'`, `'loading'`.
-- `contents`: The value represented by this `Loadable`.  If the state is `hasValue`, it is the actual value, if the state is `hasError` it is the `Error` object that was thrown, and if the state is `loading`, then it is a `Promise` of the value.
+- `state`: 表示 selector 的状态。可能的值是 `hasValue`、`hasError`、`loading`。
+- `contents`: `Loadable` 所代表的值。如果状态是 `hasValue`，它就是实际的值；如果状态是 `hasError`，它就是被抛出的 `Error` 对象，如果状态是 `loading`，那么它就是 `Promise`。
