+# arrays/slices
+
+Like tuples, arrays and slices can be destructured this way:
+
+```rust,editable
+fn main() {
+    // Try changing the values in the array, or make it a slice!
+    let array = [1, -2, 6];
+
+    match array {
+        // Binds the second and the third elements to the respective variables
+        [0, second, third] =>
+            println!("array[0] = 0, array[1] = {}, array[2] = {}", second, third),
+
+        // Single values can be ignored with _
+        [1, _, third] => println!(
+            "array[0] = 1, array[2] = {} and array[1] was ignored",
+            third
+        ),
+
+        // You can also bind some and ignore the rest
+        [-1, second, ..] => println!(
+            "array[0] = -1, array[1] = {} and all the other ones were ignored",
+            second
+        ),
+        // The code below would not compile
+        // [-1, second] => ...
+
+        // Or store them in another array/slice (the type depends on
+        // that of the value that is being matched against)
+        [3, second, tail @ ..] => println!(
+            "array[0] = 3, array[1] = {} and the other elements were {:?}",
+            second, tail
+        ),
+
+        // Combining these patterns, we can, for example, bind the first and
+        // last values, and store the rest of them in a single array
+        [first, middle @ .., last] => println!(
+            "array[0] = {}, middle = {:?}, array[2] = {}",
+            first, middle, last
+        ),
+    }
+}
+```

+# 数组/切片
+
+像元组一样，数组和切片也可以这样解构:
+
+```rust,editable
+fn main() {
+    // 尝试改变数组中的值，或者将其做成切片!
+    let array = [1, -2, 6];
+
+    match array {
+        // 将第二个和第三个元素绑定到各自的变量
+        [0, second, third] =>
+            println!("array[0] = 0, array[1] = {}, array[2] = {}", second, third),
+
+        // 单个值可以用 `_` 忽略
+        [1, _, third] => println!(
+            "array[0] = 1, array[2] = {} and array[1] was ignored",
+            third
+        ),
+
+        // 你也可以绑定一些而忽略其余的
+        [-1, second, ..] => println!(
+            "array[0] = -1, array[1] = {} and all the other ones were ignored",
+            second
+        ),
+        // 下面的代码无法编译
+        // [-1, second] => ...
+
+        // 或者将它们存储在另一个数组/切片中（类型取决于所匹配的值的类型）
+        [3, second, tail @ ..] => println!(
+            "array[0] = 3, array[1] = {} and the other elements were {:?}",
+            second, tail
+        ),
+
+        // 结合这些模式，我们可以绑定第一个和最后一个值，并将其余的值存储在一个数组中
+        [first, middle @ .., last] => println!(
+            "array[0] = {}, middle = {:?}, array[2] = {}",
+            first, middle, last
