请不要一遍又一遍地问同样的问题.如果您无法理解如此简单任务的答案，那么您应该考虑答案不会改变，您需要具备一些基本的计算机使用能力，以便能够遵循这些说明并完成此任务.向这个委员会发送相同的问题，尤其是这个简单的问题，不会在这里赢得任何朋友.

Please don''t ask the same question over and over. If you can''t understand the answers on such a simple task, then you should consider that the answer will not change, you need to get some basic computer using ability, in order to be able to follow these instructions and complete this task. Spamming this board with the same question, esp one this simple, will not win you any friends here.
