Spring and fall are usually thought to be enjoyable seasons. However, it is not always the case. {#blank#}1{#/blank#} It makes people suffer a lot from it.Why can't they find a cure（疗法）for the common cold?The answer is easy. There are actually hundreds of kinds of cold viruses（病毒） out there. You never know which one you will get.{#blank#}2{#/blank#}

    When a virus attacks your body, your body works hard to get rid of it.{#blank#}3{#/blank#} .You feel terrible because you can't breathe well, but your body is actually eating the virus.Your temperature goes up and you get a fever, but the heat of your body is killing the virus.You also have a runny nose to stop the virus from getting into your cells.You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

    {#blank#}4{#/blank#}.In China and some other countries, for example, some people might eat chicken soup to make themselves feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop various symptoms（症状）of colds.

There is one interesting thing to note-some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in your body longer because your body doesn't have a way to fight it and kill it. {#blank#}5{#/blank#}.There is a joke, however, on taking medicine when you have a cold.It goes like this: It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine. So you should trust the function of your body.

    Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.

King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend tees the opening of an exhibition of four local artists.

You could attend a class teaching you how to 'learn from the masters' or get more creative with paint —- free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

The Botanic Garden

    The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.

    The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.

    Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.

Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University, Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his roans. He spent a great deal of time walking in the village.

It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you'll take it from Virginia Woolf一—over a century after Byron, she reportedly took a trip to swim in the same pool.

    The Olympic Games are well known and always receive the world's attention, but there has been another little-known Olympic event in the UK for hundreds of years. And it's an event which some say helped start the Olympic movement in this country. The Cotswold Olimpicks take place every year on a Friday in spring. They are held in a village in England known as the Cotswold. It isn't clear when the first event took place but some say it was as early as 1612.

    The Cotswold Olimpicks were the idea of a lawyer called Robert Dover but no one knows exactly why he organized the games. Some people say he wanted to encourage people to support their king and country. Another explanation is that Dover was keen (渴望的) to bring people together, in particular the rich and poor from the local community. Whatever the reason, the yearly games quickly became popular. People competed in familiar activities such as horse-racing, running, jumping, and wrestling; famous people of the time attended it and poets wrote about the celebrations. It is even said that Shakespeare mentioned the Cotswold Olimpicks in The Merry Wives of Windsor, though the play may have been written some time before the first games.

    As the Cotswold Olimpicks grew in popularity, a group of people known as the Puritans(清教徒) started to object to them for religious reasons, saying they encouraged bad behaviour. The games came to an end at the start of the English Civil War but in 1660 they were re-introduced. Over time they became more and more popular and there are records of 30, 000 people attending in one year. However, the games also attracted people who were more interested in the celebrations than the sporting events. Finally, they came to an end once again in 1852. However, this was not the end of the Cotswold Olimpicks. They were re-introduced again in 1966 and have since been recognized by the British Olympic Committee. Out of respect to their history, the modem games are watched over by a man dressed as Sir Robert Dover, riding on horseback and accompanied by a representative of King James I. Unlike the real Olympic Games, the Cotswold Olimpicks has only about two hours and they are followed by celebrations in the village.

    Black Friday is the day after Thanksgiving Day and the Friday before Cyber Monday in the United States. It is not a federal holiday, but is a public holiday in some states. Many people take a day of their annual leave on the day after Thanksgiving Day. Some people use this to make trips to see family members or friends who live in other areas or to go on vacation. Others use it to start shopping for the Christmas season. Many organizations also close for the Thanksgiving weekend.

    Shopping for Christmas presents is also popular on Black Friday. Many stores have special offers and lower their prices on some goods, such as toys. Public transit systems may run on their normal schedule or may have changes. Some stores extend their opening hours on Black Friday. There can also be congestion on roads to popular shopping destinations.

    Black Friday is one of the busiest shopping days in the USA. There are two popular theories as to why the day after Thanksgiving Day is called Black Friday. One theory is that the wheels of vehicles in heavy traffic on the day after Thanksgiving Day left many black markings on the road surface, leading to the term Black Friday. The other theory is that the term Black Friday comes from an old way of recording business accounts. Losses were recorded in red ink and profits in black ink. Many businesses, particularly small businesses, started making profits prior to Christmas. Many hoped to start showing a profit, marked in black ink, on the day after Thanksgiving Day.

Rich as a King

    William 1, who conquered England some 930 years ago, had wealth, power and an army. Yet although William was very rich by the standard of his time, he had nothing like a flush toilet (抽水马桶), paper towels, or riding lawn mower (除草机). How did he get by?

    History books are filled with wealthy people who were poor compared to me. I have storm windows, Croesus did not. Entire nations trembled before Alexander the Great, but he couldn't buy cat food. Czar Nicholas lacked an electric saw.

    Given how much better off I am than so many famous dead people, you'd think I'd be content. The trouble is that, like most people, I compare my wealth with that of living person: neighbors, school classmates, famous TV people. The greed I feel toward my friend Howard's new kitchen is not reduced by the fact that no kings ever had a refrigerator with glass doors,

    There is really no rising or falling standard of living. Over the centuries people simply find different things to feel sad about. You'd think that simply not having disease would put us in a good mood, but no we want a hot bath too.

    Of course, one way to achieve happiness would be to realize that even by today's standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers, but even so it has a lot more rooms than my wife and I can keep clean.

    Besides, to people looking back at our era from a century or two in the future, these bankers' fancy counter tops and my awn worn Formica will seem equally shabby, I can't keep up with my neighbors right now. But just wait.

    Americans wear black for mourning (哀悼) while Chinese wear white. Westerners think of dragons as monsters. Chinese honor them as symbols of God. Chinese civilization has often shown such polarities (对立)with the West, as though each stands at extreme ends of a global string. Now in the University of California, Berkeley, a psychologist, has discovered deeper polarities between Chinese and American cultures—polarities that go to the heart of how we reason and discover truth.

    His findings go far toward explaining why American cultures seem to be aggressive and Chinese cultures so passive, when compared to each other. More importantly, the research opens the way for the peoples of the East and the West to learn from each other in basic ways. The Chinese could learn much from Western methods for determining scientific truth, said Kaiping Peng, a former Beijing Scholar, who is now a UC Berkley assistant professor of psychology. And Americans could profit enormously from the Chinese tolerance for accepting contradictions in social and personal life, he said.

    "Americans have a terrible need to find out who is right in an argument," said Peng. "The problem is that at the interpersonal level you really don't need to find the truth, or maybe there isn't any." Chinese people, said Peng, are far more content to think that both sides have advantages and disadvantages, because they have a whole awareness that life is full of contradictions. They do far less blaming of the individual than do Americans, he added.

    In studies of interpersonal (人际的) argument, for example, when subjects were asked to deal with contradictory information resulting from conflict between a mother and a daughter or a student and a school, Peng found that Americans were "non-compromising (折中), blaming one side—usually the mother—for the causes of the problems, demanding changes from one side to attain a solution and offering no compromise" in dealing with the conflict. Compared to this angry, blaming American method, the Chinese were paragons (模范) of compromise, finding fault on both sides and looking for solutions that moved both sides to the middle.
