Passage 50

(08·四川C篇)

Are you sometimes a little tired and sleepy in the early afternoon?Many people feel this way after lunch.They may think that eating lunch is the cause of the sleepiness.Or,in summer,they may think it is the heat.However,the real reason lies inside their bodies.At that time-about eight hours after you wake up-your body temperature goes down.This is what makes you slow down and feel sleepy.Scientists have tested sleeping habits in experiments where there was no night or day.The people in these experiments almost always followed a similar sleeping pattern.They slept for one long period and then for one short period about eight hours later.

In many parts of the world,people take naps(小睡)in the middle of the day.This is especially true in warmer climates(气候),where the heat makes work difficult in the early afternoon.Researchers are now saying that naps are good for everyone in any climate.A daily nap gives one a more rested body and mind and therefore is good for health in general.In countries where naps are traditional(传统的),people often suffer less from problems such as heart disease.

Many working people,unfortunately,have no time to take naps.Though doctors may advise taking naps,employers do not allow it！If you do have the chance,however,here are a few tips about making the most of your nap.Remember that the best time to take a nap is about eight hours after you get up.A short sleep too late in the day may only make you feel more tired and sleepy afterward.This can also happen if you sleep for too long.If you do not have enough time,try a short nap-even ten minutes of sleep can be helpful.

Passage 49

(08·四川B篇)

As nanny(保姆),cook,cleaner,shopper,driver,and gardener,she has one of the most demanding jobs in Britain today.And paying someone else to do the chores(家务活)which take the average housewife 71 hours a week would cost 349.

At over18,000 a year that’s more than the earnings of 70 percent of the population,including train drivers,firemen,prison officers,and social workers.

Looking after a baby less than a year old takes a housewife into an even higher pay league.According to a study,she earns457 a week-at nearly 24,000 a year,the same as teachers,engineers,and chemists.

Researchers put a price on each chore,then tried to find out how long the average person takes doing them.They found housewives spend an average 70.7　 hours a week on housework-with looking after the children(17.9 hours)and cooking and cleaning (12.3 hours each) the most time-consuming(费时的).

A wife with a part-time job still works an average of 59 hours a week at home.Those in full-time employment put in longer hours at home than in the workplace.The good news is that these hours drop sharply as children get older.While the average mother with a child under one puts in 90 hours weekly,the figure drops to 80 hours from one to four and to 66 hours from five to ten.

Mother of four Karen Williams from London said,“Paying the housewives may not be practical,but the government should recognize the value of housework, perhaps through the tax.Running a house takes a lot of time and most husbands don’t understand this.For example,my husband only puts a shelf up now and again.He never cleans the kitchen-that’s the real test.”

B.anger is less contagious than friendliness
