问题                           Accurate Timer
    These days time is everything. Between meetings and appointments, deadlines and conference calls, my schedule requires that I know the time down to the minute. Even on weekends, I have a football team to coach, shows to tape and planes to catch. If I’m late, I’m sunk. The problem is that it’s hard if my clocks aren’t correct. Even the digital clocks can display time inaccurately. Dead batteries, time changes, any of these can cause a clock to be inaccurate. Now there is no need to worry, because advanced radio technology has produced a clock which gets the time directly from the U.S. Atomic Clock in Fort Collins, Colorado, the standard for time-keeping all over the world. The Atomic Clock by Acorn is the most accurate, reliable and convenient timepiece you can have.
    Every morning at 1:00 a. m, this "smart" clock in Colorado automatically resets itself to the exact hour, minute and second. The U. S. Atomic Clock is accurate to ten billionths of a second per day. This means that the clock deviates less than one second over a one million-year period. The Atomic Clock even adjusts automatically for daylight saving time, so you don’t have to remember to "spring forward" or "fall back". The desktop clock model is the only atomic Clock that will not lose time with low power or when you change its batteries.
    The most accurate clock in the world is of no use if it is difficult to operate. The Acorn Atomic Clock is engineered in Germany using the latest scientific technology. It comes in two styles, the wall clock and the desktop model. Both are designed to be functional and easy to use. The desk clock’s display features the exact time (in hours, minutes and seconds), month and date, or you can choose to display any two U. S. or world time zones. It weighs only eight ounces, and is the perfect travel clock It also has dual alarms, perfect for couples. Both the desktop and the wall models have an internal antenna for good reception without unattractive wires.
Which of the following about the U.S. Atomic Clock is NOT true?
选项 A、It has dual alarms.
B、It has an outside antenna.
C、It is a perfect travel clock due to its light weight.
D、It displays two time zones.
答案B
解析 本题考查考生的综合判断能力。考的是有关原子钟的判断不正确的说法。选项A：它有双重闹铃。文章第三段倒数第二句话：It also has dual alarms. perfect for couples.谈到了这一点。选项C：由于重量轻，它是完美的旅行钟。文章第三段倒数第三句话：It weighs only eight ounces，and is the perfect travel clock. 谈到这一点。选项D：它显示两个时区。文章第三段倒数第四句话：The desk clock’s display features the exact time(in hours, minutes and seconds)，month and date，or you can choose to display any two U. S or world time zones.谈到它可以显示任意两个美国或世界时区。选项B：它有外置天线，这和文章第三段最后一句话：Both the desktop and the wall models have an internal antenna for good reception without unattractive wires不符，所以正确答案是B。
