课前思考：
BEFORE YOU READ1 View a video clip about the development of technology in China and discuss how technology has changed our lives.
2 How is technology changing the way we communicate
3 Based on the title of each section, what would you expect to read
We are surrounded by technologies, some of which havebecome so popular that they appear normal and part ofeveryday life. People do not even realize that they are usingthem. You might have one of these little metal deviceson your lap right now. Most technologies have made lifeeasier and more convenient as well.
Smart Mobile DevicesTablets and smart phones allow you to surf the Internet from any place offering Wi-Fi . They have successfully replaced a lot of instruments used in the past and have led to the introduction of many other devices. Phone applications allow you to check your emails, download movies, update blogs, play games, and create text documents. They are devices that can act as GPS devices, digital cameras, music players, e-readers and video viewers. They have built-in calendars and to-do lists making it easy for people to stay organized. Surely you will agree that if your smart phone were taken away from you or were running out of battery power, you could feel incomplete.
Mobile PaymentMobile payment generally refers to payment servicesperformed by a mobile device. Instead of paying in cash or by credit cards, a consumer can use a mobile device to pay for a wide range of services and goods. By scanning a QR code, short for “Quick Response” code, with a mobile phone, people can pay immediately in restaurants, supermarkets and convenient stores. The technology supporting such systems has become widely available. It makes operations efficient and convenient, resulting in an increase in business.
Wearable DevicesLifestyle and fitness devices have become very popular in recent years. There are many wearable devices on the market for you to choose from. Wearable devices track your steps, workout time, calories burned and distance you cover. In addition, they are in a position to measure the rate of your heart beat and monitor how you sleep. Some are worn on the ankle or wrist, while others are clipped onto clothes or put around the chest.
