Language Points gadgets n. 小物件, 小机械 pedometer n. 记步器, 记程器 vibrate v. 震动 beep v. 发出嘟嘟声

Culture note v v Pedometer: is a pager-sized device worn on your belt that simply records the number of steps you take based on your body's movement. Some pedometers are analog devices that simply measure steps. Some are fancier digital models that track the distance you walk, plus the calories you burn. But keep in mind, the calorie counters are notoriously inaccurate and those models are more expensive. All you really need is a simple step counter so you can monitor if you walk the recommended 10, 000 steps per day. A pedometer is great for the gadget lovers out there. It's also ideal for the person who simply can't find a hunk of 30 minutes-or even three chunks of 10 minutes-in a day for walking. Just be sure to put a safety string through the pedometer's waist clip and pin it or loop it through a belt loop, so the pedometer isn't dropped down a toilet.

Culture note In many countries people are becoming more aware that their use of technology in public places affects other people. For example, most people think it is not polite to use cell phones while using public transportation. Before many events, there announcements and signs that ask people to turn off their electronic devices before the event begins so that they don’t interrupt the performance. There is also more awareness about how electronic equipment may affect people’s health.
