【简答题】
下面文章有5处(第1-5题)需要添加小标题. 请从以下选项(A、B、C、D、E和F)中选出符合各段意思的小标题, . 选项中有一多余选项. A.The world is running  out of time as watches don't function well. B.It is uncertain that watches will remain popular. C.Some people claim that the watch industry is at a crossroads. D.The function of a watch has changed to stay on the market. E.New designs for a watch make it appeal to customers. F.The image of a watch satisfy many different tastes. _______1. In today's world of cell phones, mini laptops and MP3 players, most people have at least one time-telling tool with them. Since these devices are so common, is time running out for the 500-year-old watch? According to some consumers, yes. New Jersey teenager Charlie Wollman says a watch is 'an extra piece of equipment with no necessary function.' Many young adults agree and they say they use their cell phones to tell time. Louis Galie, a senior vice president at Timex, said that fewer young people wear watches today than five years ago. _______2. However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality timepiece that doesn't just keep good time. Fifty years ago, watchmakers laid great emphasis on products' accuracy. But in recent years, the watch industry has transformed itself into an accessory business. And for many today, the image a watch communicates has become more important than the time it tells. _______3. 'Complications'-features that go beyond simple timekeeping-are an important part of a watch's image. Today's watches offer a host of features that suit almost any personality. These features include altitude trackers, compasses, lunar calendars, USB drives, and even devices that measure the effectiveness of golf swings. _______4. Creativity is also a key element in today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell the time. It looks more like a Futuristic bracelet than a watch. Another Japanese watchmaker, Eleeno, makes a 'handless' watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece. _______5. Whether a watch communicates fashion sense, creative flair or a love of sports, consumers want their timepieces to stand out. Nowadays, everyone has the same kind of gadget(小器械) in their bags, so people want to make a statement with what's on their wrists. Will this interest in wrist fashion
