　　Sunday is more like Monday than it used to be．Places of business that used to keep daytime “business hours” are now open late into the night．And on the Internet, the hour of the day and the day of the week have become irrelevant．A half century ago in the United states, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time．Today the dividing lines are still there, but they seem not clear．

　　The law in almost all states used to require stores to close on Sunday; in most, it no longer does．It used to keep the schools open in all seasons except summer, in most, it still does．And whether the work week should strengthen its legal(法律的)limits, or whether it should become more changeable, is often debated(争论)．How should we, as a society, organize our time? Should we go even further in relaxing the dividing lines of time until we live in a world in which every minute is much like every other?

　　These are not easy questions even to ask．Part of the difficulty is that we seldom recognize the “law of time” even when we meet it face to face．We know as children that we have to go to school a certain number of hours, a certain number of days, a certain number of years – but unless we meet the truant officer(学监), we may well think that we should go to school because of social custom and parents’ requirement rather than to the law．As adults we know “extra pay for overtime working” very well, but less familiar with the fact that what constitutes(构成)“overtime” is a matter of legal thing．When we turn the clock forward to start daylight-saving time, have we ever thought to ourselves：“Here is the law in action”? As we shall see, there is a lot of law that has great influence on how organize and use time：compulsory education law, overtime law, and daylight-saving law-as well as law about Sunday closing, holidays, being late to work, time zones, and so on．Once we begin to look for it, we will have no trouble finding a law of time to examine and assess．

　　Even though global warming may have made the weather more mild, many animals are still hibernating(冬眠)．It's too bad that humans can't hibernate．In fact we almost did．

　　Apparently, at times in the past, farmers in France liked a semi-state of human hibernation．So writes Graham Robb, a British scholar who has studied the sleeping habits of the French farmers．As soon as the weather turned cold, people all over the France shut themselves away and practiced the forgotten art of doing nothing at all for months．

　　In line with this, Jeff Warren, a producer at CBC Radio's The Current, tells us that the way we sleep has changed since the invention of lighting．

　　When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though．Now scientists are telling us our ancestors most likely slept in separate periods．The business of eight hours’ continuous sleep is a modern invention．

　　In the past, without the artificial light, humans went to sleep when it became dark and then woke themselves up around midnight．The late night period was known as “The Watch”．It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbors．

　　According to some sleep researchers, a short of insomnia(失眠)at midnight is not a disorder．It is normal．Humans can experience another state of consciousness(清醒状态)around their sleeping, which happens in the brief period before we fall asleep or wake ourselves in the morning．This period can be a creative time for some people．

　　Playing with your sleep rhythms(节奏)can be dangerous, as worry may set in．Medical science doesn't help much in this case．It offers us medicines for a full night's continuous sleep, which sounds natural; however, according to Warren's theory, it is really the opposite of what we need．

　　What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?

　　Yes, there really is a job where you can get paid to taste ice cream．Just ask John Harrison, an “Official Taste Tester” for the past 2l years．Harrison's job has been responsible for approving(批准)large numbers of the sweet ice cream-as well as for developing over 15 flavors(味道)．

　　Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No-there's more to the job than that, says Harrison, who has a degree in chemistry．He points out that a dairy or food-science degree would be very useful to someone wanting a job in this “cool field”．

　　In a typical morning on the job, Harrison tastes and grades 60 ice-cream samples．He lets the ice cream warm up to about 12^oF．Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup．”

　　While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance．“Tasting begins with the eyes, ” he explains．He checks to see if the ice cream is attractive and asks himself, “Does the product have the colour expected from that flavor? ” Next it's time to taste!

Continuing to think up new ideas, try out new flavors and test samples from so many kinds of ice cream each day keeps Harrison busy but happy – working at one cool job．

　　A young man was going to join the army(部队)and had to take a medical examination(检查)．The doctor was sitting at a desk when he went in．He said to the man, "Take your coat and shirt off, and sit on that chair．"

　　The young man did so．The doctor looked at him for a moment without getting up from his chair and then said, " All right．Put your clothes on again．"

　　" But you haven't examined me at all! " the young man said in surprise．

　　"There is no need to do so, " the doctor said with a smile．"When I told you to take your coat and shirt off, you heard me all right, so there is nothing wrong with your ears．You saw your chair, so your eyes are good．You could take your clothes off and sit on the chair, so you must be in good health．And you understood what I told you to do and did it without a mistake, ．．．"

　　Can plants eat people? Probably(可能)not, but there are many plants that eat meat．Some of them are big, and they can eat small animals．One famous(著名的)meat-eating plant is the Venus flytrap(捕蝇草)．

　　The Venus flytrap is a very strange(奇怪的)plant．It grows in dry parts of the USA．Its leaves(叶子)are like the pages of a book．They can open and close very quickly．Inside the leaves, there are three small hairs．If a fly(苍蝇)touches(触及)one of the hairs, the leaf closes quickly．The fly cannot get out．In about half an hour, the leaf presses the fly until it is dead(死亡)．Then, the plant covers the fly．Slowly, the plant eats the fly．

　　Why do plants do it? Most plants get what they need from the sun, the air, and the ground．In some places, the ground is very poor．It doesn't have all these important things, especially(特别)nitrogen(氮), Animal meat has a lot of nitrogen, so some plants eat meat to get what they need．Let's hope that some of the bigger plants don't get the same idea!

　　You are probably familiar with the saying：An apple a day keeps the doctor away．A recent research carried out by the Chinese University of Hong Kong may change the saying：

　　An apple a day may keep aging away．

　　The research chose fruit flies(果蝇), as they share many genes(基因)with humans．The fruit flies were either fed normally or had an apple extract(浓缩物)added to their diet．

　　It turned out that those fruit flies that were given apple extract lived about 55 days－five days longer than the flies that were normally fed．The research group also found it easier for the flies to walk，climb and move about as they aged．

　　According to the result, the researchers believed that the antioxidants(抗氧化剂)in the apple extract helped clean up dangerous chemicals(化学物质)that cause illnesses，as well as aging．

　　In another study，researchers examined diets of thousands of women．They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke．

　　The apples' genetic code(遗传密码)was discovered recently．It allows scientists to develop nicer and healthier fruits．Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer．

　　Apples that kill the desire(欲望)to eat could also be produced, with the first“extra-healthy''apples on supermarket shelves within just four or five years．

　　The team that keeps studying apple DNA includes 100 scientists from five countries．Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant，which would finally become today's apple tree, experienced a great genetic change．The number of many of its genes doubled．The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches，strawberries and other related fruits．

　　For a long time being happy was considered natural，and there was nothing special to do about it．Now we know that we can work at getting along well with other people．It is possible to act in such a way that other people will like us better．

　　One way is being unselfish，not wanting everything your own way or asking for the best share of everything, including the attention of your friends．Another way is to look for good points, not bad ones in other people．

　　You don't have to be spineless(无骨气的)in order to be popular．In fact，you will be liked and respected(尊重)if you are not afraid to stand up for your rights(权利)．But do it politely and pleasantly．One way to develop a good character is being friendly and polite to your own group, to older people，to strangers and especially to those who do not look important or do not interest you．

　　You cannot expect to be perfect, so you must learn not to be too unhappy when you make a mistake．Everyone makes mistakes, and no one is to be blamed unless he refuses to learn from them．Many young people become discouraged(泄气的)when they know their unpleasant qualities－selfishness，laziness，etc．Just remember that we all have some of these faults and have to fight against them．

　　When something is wrong，it is best to try to make it right．Perhaps you don't like a teacher or a classmate．Try to see why，and look at yourself，too．Make sure that you are not doing something to make others dislike you．In time, things may turn out all right, then you simply have to learn to get along the best you can with the situation, without thinking too much about it．Worrying never helps in a situation you can't change．
