They wear the latest fashions with the most up-to-date accessories(配饰). Yet these are not girls in their teens or twenties but women in their sixties and seventies．A generation which would once only wear old-fashioned clothes is now favouring the same high street looks worn by those half their age．

    Professor Julia Twigg, a social policy expert, said, “Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s．In the 1960s buying a coat for a woman was a serious matter．It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whenever you wish to．Fashion is a lot cheaper and people get tired of things more quickly.”

    Professor Twigg analysed family expenditure(支出) data and found that while the percentage of spending on clothes and shoes by women had stayed around the same — at 5 or 6 percent of spending — the amount of clothes bought had risen sharply．

    The professor said, “Clothes are now 70 percent cheaper than they were in the 1960s because of the huge expansion of production in the Far East．In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere．Everyone is buying more clothes but in general we are not spending more money on them．”

    Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected by the celebrity(名流) style than in previous years．

    She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them．Older women are much more aware of celebrities. There's also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties．When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women．My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago．”

    It was a late Wednesday night when the dreading phone call reached our home. I sat up, somehow terrified, so I could hear the phone call better. To my surprise, I heard my mom burst into tears. “Get the car, Dean! Andrea has been in a car accident.”

    We ran every stop sign on the way to the hospital and our tires screeched around every corner. We got to the hospital, but were not allowed to see Andrea. The next morning, after wearing masks, we were allowed to go to the ICU to see Andrea. Well, the least I could say was that everything was injured in her body and she lost all of her memories. It was a fatal accident.

    Over the next two months, I lived more at the hospital than I did at my house. I watched as Andrea worked so hard to gain back everyday motor skills. She never once complained or pitied herself; her determined spirit was shining through. After two weeks in the ICU and two months of the regular hospital treatment, Andrea was able to come home. She missed several months of school, so it was hard for her to catch up. Andrea had tasks to accomplish, and no matter how hard it was, she stuck with them until the job was done. Though busy with dealing with pain and therapy, she always found time to love and play with me.

    I'll never forget the impact that this incident made on my life. I admire her strong-willed personality and her determined spirit. Today she is perfectly normal, despite the scars and the pins holding her leg in place. I couldn't ask for a better sister, hero, or best friend.

    In every British town, large and small, you will find shops that sell second-hand goods. Sometimes such shops deal mostly in furniture, sometimes in books, sometimes in ornaments（装饰） and household goods, sometimes even in clothes.

    The furniture may often be “antique”, and it may well have changed hands many times. It may also be very valuable, although the most valuable piece will usually go to the London salerooms, where one piece might well be sold for hundreds of thousands of pounds. As you look around these shops and see the polished wood of chests and tables, you cannot help thinking of those long-dead hands which polished that wood, of those now-closed eyes which once looked at these pieces with love.

    The books, too, may be antique and very precious; some may be rare first printings. Often when someone dies or has to move house, his books may all be sold, so that sometimes you may find whole libraries in one shop. One the border between England and Wales, there is a town which has become a huge bookshop as well. Even the cinema and castle have been taken over, and now books have replaced sheep as the town's main trade.

    There are also much more humble shops, sometimes simply called “junk shops”, where you can buy small household pieces very cheaply. Sometimes the profits（利润）from these shops go to charity（慈善事业）. Even these pieces, though, can make you feel sad; you think of those people who once treasured them, but who have moved on to another country or to death.

    Although the British do not worship（崇拜）their ancestors, they do treasure the past and the things of the past. This is true of houses as well. These days no one knocks them down; they are rebuilt until they are often better than new. In Britain, people do not buy something just because it is new. Old things are treasured for their proven worth; new things have to prove themselves before they are accepted.

    Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads.

    The review explains that smell is unique in its effects on the brain. According to Conrad King, the researcher who carried out the review, "more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentions of a dieter."

    Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000 genes (基因), which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.

    According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.

    In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers' impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.

    However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may explain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.

    Barbara McCintock was one of the most important scientists of the twentieth century. She made important discoveries about genes(基因) and chromosomes (染色体).

    Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to Brooklyn area of new York City in 1908.Barbara was an active child with interests in sports and music. She also developed an interest in science.

    She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.

    Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed a master's degree in 1925. Two years later, she finished all her requirements for a doctorate degree.

    McCintock stayed at Cornell after she completed her education. She taught students botany. The 1930s were not a good time to be a young scientist in the United States. The country was in the middle of the great economic Depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.

    An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started in a temporary (临时的) job with the genetics department. A short time later, she accepted a permanent (永久的) position with the laboratory. This gave her the freedom to continue her research without having to teach or repeatedly ask for financial aid.

    By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.
