在声明局部变量的函数中，只有局部版本才具有意义。

Inside the function in which the local variable is declared, only the local version has meaning.

就像很多语言中声明局部变量一样，一个嵌套方法尽在方法内部可见。

Like a local variable declaration in many languages, a nested method is only visible inside the enclosing method.

声明局部变量后，子例程将遍历每个指定查询词，搜索name或jobresponsibilities散列中的变音位匹配。

After the local variable declaration, the subroutine will make a pass through every query word specified searching for a metaphone match in the name or jobresponsibilities hashes.

And when you declare a variable, whether as an argument or as literally a local variable, they only live inside of that function.

当你声明一个变量，不论是一个参数,还是一个局部变量，它们只存在函数的内部。
