题目内容：
Questions are based on the following passage． When it's five o'clock, people leave their office．The length of the workday, for many workers, isdefined by time．They leave when the clock tells them they're done．
These days, the time is everywhere: not just on clocks or watches, but on cell-phones andcomputers．That may be a bad thing, particularly at work．New research shows that clock-based workschedules hinder morale (士气) and creativity．
Clock-timers organize their day by blocks of minutes and hours．For example: a meeting from9 a．m．to 10 a．m．research from 10 a．m．to noon, etc．On the other hand, task-timers have a list ofthings they want to accomplish．They work down the list, each task starts when the previous task iscompleted．It is said that all of us employ a mix of both these types of planning．
What, then, are the effects of thinking about time in these different ways? Does one make us moreproductive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet andAnne-Laure Sellier, they had participants organize different activities-from project planning, holidayshopping, to yoga-by time or to-do list to measure how they performed under "clock time" vs "tasktinge．" They found clock timers to be more efficient but less happy because they felt little control overtheir lives．Task timers are happier and more creative, but less productive．They tend to enjoy themoment when something good is happening, and seize opportunities that come up．
The researchers argue that task-based organizing tends to be undervalued and under-supported inbusiness culture．Smart companies, they believe, will try to bake more task-based planning into theirstrategies．
This might be a small change to the way we view work and the office, but the researchers arguethat it challenges a widespread characteristic of the economy: work organized by clock time．Whilemost people will still probably need, and be, to some extent, clock-timers, task-based timing shouldbe used when performing a job that requires more creativity．It'll make those tasks easier, and the task-
doers will be happier．
What does the author think of time displayed everywhere? A．It makes everybody time-conscious．
B．It is a convenience for work and life．
C．It may have a negative effect on creative work．
D．It clearly indicates the fast pace of modern life．
