    When Allison Winn was eight and her family adopted a dog named Coco, they had no idea how much the little creature would change her life. “Coco helped me feel better,” says Allison, who was recovering from l4 months of treatment for a brain cancer at the time. “She would cuddle（偎依) with me when I didn't want to play.” Allison loved Coco so much that she told her parents she wanted to help other sick kids find the same kind of comfort.

    She started small, raising money by selling lemonade and home-made dog biscuits in front of her house. Her first customer was the mailman. By the end of that summer, she had raised nearly $l,000, enough to adopt and train two dogs and give them to children with cancer. Now, a little more than two years later, some groups gather to make dog treats for Allison's cause.

    Her organization, the Stink Bug Project, named after a picture she drew in memory of the end of her treatment, is run and managed in partnership with the Morgan Adams Foundation. Stink Bug helps families adopt pets from the Trained K9 Companion Program, where the rescued dogs are taught commands. Allison's mother, Dianna Litvak, who helps run Stink Bug, hopes to extend the pet-adoption program statewide and continue donating some of the money to help fund children's cancer research.

    “Allison has figured out how to help - in a way that no one else has,” Litvak says. “We involve her younger sister, Emily, her friends, the adopting families, and some others. It took the love of a little girl to wrap all that together into one amazing package.”

    Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist (免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    Gardening is a very popular hobby. And it is one that produces wonderful results – food for your dinner table and flowers for your home! Gardens themselves can be very beautiful. So you would think that a garden path is a great place to be. Well, in conversation, it is not. Leading someone up the garden path means you are trying to trick them. You are not trying to show them your beautiful flowers.

    Speaking of beautiful flowers, gardeners love to see small buds (芽) forming on their plants. Besides plants and flowers, people can bud, too. If a child is good at drawing and painting, we can call him a budding artist. So “budding” describes something that is beginning to develop.

    On the opposite end, you stop something from growing if you nip it in the bud. This is a common expression when we talk about stopping something bad and preventing it from continuing. It's good to nip small problems in the bud before they turn into big problems.

    Now flowers that bloom （开花）are beautiful to see – even garden-variety flowers. “Garden-variety” describes anything that is common and not so special. You can have a garden-variety cold—not a serious illness.

    Now, a problem that many gardeners have is weeds. Weeds grow easily and can quickly take over a garden. In conversation, we sometimes use “weeds” to mean too many details. So, if you are in the weeds, you are taken over by too many details.

    As we said, weeds grow quickly. So do children. So, we like to say a child grows like a weed. This expression compares a child's fast growth to that of a weed.

    Fix it on your own

    Did you know that a bowl of rice could save your iPod if you drop it in a swimming pool by accident? Or that the camera on your phone could tell you what's wrong with your TV remote control(遥控器)? The experts at Geek Squad have made a gadget (小机件) rescue guide. So, let's take a look at some of their useful advice.

    How to get more juice out of your phone battery (电池)

    If your battery goes dead but you need to get a number or send one last text, try warming it up. That may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm it under your arm for a few minutes. Then try to start the phone-but use it quickly.

    What to do if your gadget gets wet

    First, try drying it out with a vacuum cleaner(真空吸尘器). If a vacuum cleaner isn't at hand, fill a pot or bowl with uncooked rice and put your wet gadget inside. The dry, uncooked rice will absorb all the water and, after a few hours, you should be able to use the gadget. Don't forget to remove the battery and SIM card before you dry it.

    What to do if your TV remote control stops working

    If replacing the batteries doesn't work, get the camera function up on your phone and point the remote at the lens (镜头). When you press a button on the remote, if it is working, the glass bobble (小球) at the front of the remote will light up when you look at it on the screen of your phone. This is because the screen on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble doesn't light up, the remote is broken. If it does, the receiving device is broken.

    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.

    David Brown and Anne are two patients in the Adult Day Care Program at Mercy Hospitals. David Brown is seventy-two years old. He's friendly and likes to talk. He lives with his wife in the city. But David is becoming forgetful. His wife says, “He'll heat up some soup, then forget to turn off the gas.” She is sixty-one and still works. She is worried about leaving her husband alone.

    Anne is eighty and lives with her 60-year old daughter. Her daughter says that she needs a rest. “Mom follows me everywhere. She follows me when I read newspapers. I need a rest and she does, too.”

    And so, several times a week, David and Anne's families take them to the Adult Day Care Center. Many hospitals have this program, Patients come to the Center for a full or half day, from one to five days a week. All the patients live with their families and most are old people.

    Mrs. Carol Johnson is the director of the Center. She says, “We help the patients learn many things here. Patients have the chance to get out of their houses. Husbands, wives or grown children can work or have a rest. Most important of all, families are able to stay together.”
