Hello,everyone!Today is my turn to make a speech.I’m going to talk about computer security.Everyone knows that Windows XP is a famous operating system.There are 30% PCs using Windows XP now.But Windows XP is old.Many games and software will not support Windows XP.On April 8,2014,support and updates for Windows XP will no longer be available.In the meantime,malware's favorite target is the older Windows XP.You can reduce the risk by using a mac,or by upgrading from the insecure Windows XP to Windows 8.1,and installing anti-virus software.Windows 8.1 is faster,safer and more powerful than Windows XP.You can visit Microsoft Developer Center or msdn.itellyou.cn to download Windows 8.1.You can also buy it from Microsoft Store.That‘s all,thank you!

今天輪到我為大家做演講.我將要討論計算機安全.眾所周知,Windows XP是一個著名的操作系統(tǒng),有30%的計算機正在運行Windows XP.但Windows XP已經(jīng)舊了,許多游戲和軟件將不再支持Windows XP.在2014年4月8日,Windows XP的支持和更新將會終止.同時,惡意軟件愛好者的目標還是那些老的Windows XP.為了減少風險,你可以使用MAC,或由不安全的Windows XP升級到Windows 8.1,并安裝防病毒軟件.Windows 8.1比Windows XP更快、更安全也更強大.你可以訪問微軟開發(fā)者中心或msdn.itellyou.cn來下載Windows 8.1,你也可以從微軟商城購買.這就是全部,
