问题 Wireless phones are available on today’s consumer market. Like most people, you’re probably interested in a little handheld number. They’re small and light. Transmitting(发送) 0.2 to 0.6 watt of power, these wireless phones come in a variety of models, digital cellular and digital PCS ( personal communications service) models, as well many cool shapes and colors.
How do you choose a mobile when two or three models look equally good? Think about these characteristics:
A big, bright display--The more you use your phone, the more you’ll appreciate an ease-to-read display.
Light weight--Most wireless phones these days are tiny, so why take a 10-ounce model when a 6-ounce one works just as well?
Accessories(配件)--If you want a certain type of hands-free car kit(成套用具) or other accessory, make sure it’s available for your specific phone;
Battery life--Look for a phone that allows you to talk for a long time;
External volume control--Take a phone with an external volume control. You’ll appreciate it the first time you use it in a noisy place;
Easy ringer volume control--Buy a phone that rings loudly enough for a moderately noisy environment, but is easy to tone down for, say, a funeral. Even better, get a phone with a vibrating alert.

选项 A、they send out a little amount of watt of power
B、they have many cool shapes and colors
C、they are small and light
D、they are easy to buy on market

答案 C

解析题干意为“手提无线电话受到大多数人欢迎是因为…”。该题为细节题。根据第一段的第二、三句话可知，手提无线电话受到大多数人欢迎是因为它们又小又轻。
