-#### Parameters {/*parameters*/}
+#### 参数 {/*parameters*/}
 
-* `element`: The `element` argument must be a valid React element. For example, it could be a JSX node like `<Something />`, the result of calling [`createElement`](/reference/react/createElement), or the result of another `cloneElement` call.
+* `element`：`element` 参数必须是一个有效的 React 元素。例如，它可以是一个类似 `<Something />` 这样的 JSX 节点，也可以是 [`createElement`](/reference/react/createElement) 调用的结果，或者也可以是另一个 `cloneElement` 调用的结果。
 
-* `props`: The `props` argument must either be an object or `null`. If you pass `null`, the cloned element will retain all of the original `element.props`. Otherwise, for every prop in the `props` object, the returned element will "prefer" the value from `props` over the value from `element.props`. The rest of the props will be filled from the original `element.props`. If you pass `props.key` or `props.ref`, they will replace the original ones.
+* `props`：`props` 参数必须是一个对象或 `null`。如果传 `null`，克隆后的元素将保留所有原始的 `element.props`。否则，对于 `props` 对象中的每个 prop 属性，返回的元素将“优先”使用 `props` 中的值而不是 `element.props` 中的值。其余的 props 将从原始的 `element.props` 中填充。如果你传递 `props.key` 或者 `props.ref`，它们将替换原来的。
 
-* **optional** `...children`: Zero or more child nodes. They can be any React nodes, including React elements, strings, numbers, [portals](/reference/react-dom/createPortal), empty nodes (`null`, `undefined`, `true`, and `false`), and arrays of React nodes. If you don't pass any `...children` arguments, the original `element.props.children` will be preserved.
+* **可选** `...children`：零个或多个子节点。它们可以是任何 React 节点，包括 React 元素、字符串、数字、[portals](/reference/react-dom/createPortal)、空节点（`null`、`undefined`、`true` 和 `false`），和 React 元素数组。如果你不传递任何 `...children` 参数，则原始的 `element.props.children` 将被保留。
 
-#### Returns {/*returns*/}
+#### 返回值 {/*returns*/}
 
-`cloneElement` returns a React element object with a few properties:
+`cloneElement` 返回一个具有一些属性的 React element 对象：
 
-* `type`: Same as `element.type`.
-* `props`: The result of shallowly merging `element.props` with the overriding `props` you have passed.
-* `ref`: The original `element.ref`, unless it was overridden by `props.ref`.
-* `key`: The original `element.key`, unless it was overridden by `props.key`.
+* `type`：与 `element.type` 相同。
+* `props`：将 `element.props` 与你传递的 `props` 浅合并的结果。
+* `ref`：原始的 `element.ref`，除非它被 `props.ref` 覆盖。
+* `key`：原始的 `element.key`，除非它被 `props.key` 覆盖。
 
-Usually, you'll return the element from your component or make it a child of another element. Although you may read the element's properties, it's best to treat every element as opaque after it's created, and only render it.
+通常，你将从组件返回该元素或使其成为另一个元素的子元素。尽管你可以读取元素的属性，但最好在创建每个元素后将其视为不透明的，并且仅渲染它。
 
-#### Caveats {/*caveats*/}
+#### 注意事项 {/*caveats*/}
 
-* Cloning an element **does not modify the original element.**
+* 克隆一个元素 **不会修改原始元素**。
 
-* You should only **pass children as multiple arguments to `cloneElement` if they are all statically known,** like `cloneElement(element, null, child1, child2, child3)`. If your children are dynamic, pass the entire array as the third argument: `cloneElement(element, null, listItems)`. This ensures that React will [warn you about missing `key`s](/learn/rendering-lists#keeping-list-items-in-order-with-key) for any dynamic lists. For static lists this is not necessary because they never reorder.
+* 如果已知 children 是静态的，则你应该 **将它们作为多个参数传递给 `cloneElement`**，例如 `cloneElement(element, null, child1, child2, child3)`。如果你的 children 是动态的，请将整个数组作为第三个参数传递：`cloneElement(element, null, listItems)`。这确保了 React 会对任何动态列表 [警告你缺少“key”](/learn/rendering-lists#keeping-list-items-in-order-with-key)，对于静态的列表，这是不必要的，因为它们不会重新排序。
 
-* `cloneElement` makes it harder to trace the data flow, so **try the [alternatives](#alternatives) instead.**
+* `cloneElement` 会使得跟踪数据流向变得更加困难，所以请 **尝试使用 [替代方案](#alternatives)**。
