看见这台ATM机了吧，就像你在其他地方看见的一样。不过，你是否想过它里面有什么呢？它里面到底有多少钱？钱都藏在哪儿呢？如果你到ATM机后面把它打开，你会看到几件你期望在那里看到的东西。比如，一台电脑——与普通台式电脑没有太大区别。这台电脑与ATM网络相连接。那里还有一个电脑控制面板，以及一台打印所有收据凭证的打印机。ATM机最酷的部分要数它里面的保险箱了，它存着所有的钱。打开保险箱，你会看见一组装着全部现金的小盒子。将钱装在盒子里，然后将盒子安在ATM机中。这种规格的每个盒子可以装25万美元。
You see an ATM like this just about everywhere you go now. But have you ever wondered what＇s inside？ How much money is actually in there and where does it all come from？ When you go to the back of an ATM and open it up, you find a couple of things that you would expect to find there. For example, there is a computer that＇s not too different from a normal desktop computer. The computer connects to the ATM network. There＇s also a control panel for the computer, and there＇s a printer that prints out all the receipts.
