     True to their reputation as leisure-loving gourmets(美食家),the French spend more time

sleeping and eating than anyone else among the world's wealthy nations,according to a study

published on Monday.

     The average French person sleeps almost nine hours every night,more than an hour longer

than Japanese and Korean,who sleep the least in a survey of 18 members of the Organization

for Economic Cooperation and Development (OECD).Despite their siesta(午睡)habit,Spaniards

rank only third in the poll after Americans,who sleep more than 8.5 hours.

     And while more and more French people grab a bite at fast-food chains these days or,wolf

down a sandwich at their desk,they still spend more than two hour's a day eating.

     That means their meals are twice as long as those of the average Mexican,who dedicates just

over an hour a day to food,the OECD's "Society at a Glance" report on work,health and leisure

in Asia,Europe and North and South America found. The Japanese,scrimping (吝啬) on sleep

and burdened with long working hours,still manage to spend close to two hours a day eating and

drinking,placing them third behind New Zealanders.  

     Despite the limited amount of time Americans spend eating each day-about an hour and a

quarter-U.S. obesity肥胖) rates are the highest in the 30 members of OECD.

     The Japanese like to spend what remains of their rare free time watching television or listening

to the radio. This takes up 47 percent of leisure time in Japan. Norwegians spend the most time at

leisure,just over a quarter of their day,while at the low end,Mexicans spend just 16 percent of their

time having fun.
