Obviously，there would be no point in investing in a computer if you had to check all its answers，but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.
显然，如果你不得不检查计算机提供的所有答案的话，对它投资就没有任何意义了。但是当人们觉的计算机确实出了一些问题的时候，应该靠自己内部的“计算机”来检查机器。
