 # 14.6 协程和recover
 
+一个用到`recover`的程序（参见章节13.3）停掉了服务器内部一个失败的协程而不影响其他协程的工作。
+```go 
+func server(workChan <-chan *Work) {
+    for work := range workChan {
+        go safelyDo(work)   // start the goroutine for that work
+    }
+}
+
+func safelyDo(work *Work) {
+    defer func {
+        if err := recover(); err != nil {
+            log.Printf("Work failed with %s in %v", err, work)
+        }
+    }()
+    do(work)
+}
+```
