Mary: Phone technology is updating again. Many companies-Nokia, Ericsson. Motorola and Samsung are ready to offer completely updated technology.
玛丽：电话技术又在更新了。许多公司，包括诺基亚、爱立信、摩托罗拉和三星公司等都在进行科技上的更新换代。
John: Yeah. I heard something about that.
约翰：是的。我也听说了。
Mary: I heard about something called W-CDMA which is supposed to rival CDMA in bandwidth but much cheaper.
玛丽：我还听说一种称为W-CDMA的技术在带宽方面可与CDMA抗衡，而且费用还便宜得多。
John: My friend told me that there is a new short distance radio technology.
约翰：我朋友告诉我现在有一种新的短距离无线通信技术。
Mary: You must be talking about Bluetooth. It's a wireless technology and is supposed to almost totally replace wiring of all kinds. Soon you'll be able to dial up your friends
using just a headset. The rest of your phone will be on your belt.
玛丽：你说的一定是蓝牙技术。那是一种无线技术，旨在希望可以取代各种各样的配线。不久你就能用耳机拨号和你的朋友联系了。电话的其他装置可以挎在腰带上。
John: It sounds like we'll be able to communicate with appliances like my fridge.
约翰：听起来好像还可以和冰箱之类的家用电器通话似的。

place its own order when it is empty.
玛丽：一旦完成了下一阶段的智能家电的研发，理论上你就能通过手机往冰箱里放东西了。以后，你的冰箱空了的时候还能自己订货呢。
John: Wow! Is it truly that significant? It sounds like soon I'll never have to leave my apartment.
约翰：喔！真有那么神奇吗？听起来好像我以后再也用不着出门了。
