    Go to church, then have a big lunch, then go out to play while mum does the housework. That was a

typical (典型的) British Sunday in the 1960s. But things now could not be more different. 

    Some British sociologists recently studied the typical British Sunday. They found that people get up later

and do less housework than they did 40 years ago. They are far more likely to be out shopping or enjoying

themselves than cooking Sunday lunch. 

    Sunday mornings were busy 40 years ago. Most women caught up on their weekly housework and

cooked a nice lunch. They seldom allowed themselves any "leisure" until afternoon, after the dishes were

cleaned. Then there would be another rush to the table between 5:00 pm and 6:00 pm for tea. But now,

Britons can have brunch (早午餐) at the restaurant. Fewer people bother to cook themselves. "You only

have two free days a week. You don't want to have to waste one because there is nothing to do but watch

boring TV," said Elizabeth Biggs, 25, a producer in London. 

    "On Saturday you are recovering from the week," Biggs added. "Sundays are the last chance for the

weekend - you want to get as much as you can out of the day before you have to go back to work." In

the past, British women usually did their shopping during the week, while the husband was at work. "Now

men seem to do that as much as women," said Jonathan Gershuny, a professor who took part in the study.

    Men also do more housework now on Sundays. Back in the 1960s, men were far more likely to spend

Sundays out of the house at the pub or playing football before lunch.
