这是我参与「第三届青训营 -后端场」笔记创作活动的的第1篇笔记 主要是并行调用线程 实现调用两个翻译接口，实现结果，熟悉下线程的使用方法

func main() {
if len(os.Args) != 2 {
fmt.Fprintf(os.Stderr, `usage: simpleDict WORD
example: simpleDict hello
`)
os.Exit(1)
}
word := os.Args[1]
wg := sync.WaitGroup{} //创建等待线程组
wg.Add(2) //等待组的计数器 +2
go query(word, &wg) //调用线程，维护公共变量 wg
go huoshanquery(word, &wg) ////调用线程 维护公共变量 wg
wg.Wait() //当等待组计数器不等于 0 时阻塞直到变 0。
}
主要是 main方法中的创建等待线程组，使用等待线程组为公共变量，等待组的计数 没到0，那么线程会一直等待 当翻译函数调用完成 ，defer wg.Done() 会执行，把等待组的计数-1，当到0 的时候 就会停止线程等待
