If you watch British television on Friday March 15,you might be surprised to see celebrities wearing funny red noses and joking around. But don't worry. They're not mad. It's all part of a biannual fund-raising event called Red Nose Day.

    Organized by the charity Comic Relief, founded in 1985 by two British comedians, the aim of the event it is to raise money to fight poverty and injustice in the UK and Africa. Celebrities and public figures support the event by making appearances on comic TV shows broadcast by the BBC. This year, for example, UK Prime Minister David Cameron appeared in a music video by One Direction, which the band produced for the event.

    But Britons don't just raise money for charitable causes on one day a year. They do it all year round. One way of doing so is-by shopping in charity shops. These small, inconspicuous shops sell clothes, books and household goods just like any other shop But there's one big difference—everthing sold in the shops is second-hand.

    There are nearly 10,000 charity shops in the UK, according to the Charity Retail Association. Their business model is simple: Anybody who has things they don't want anymore can donate them to a charity shop, where they are checked for damage, cleaned and priced. Most items go back on sale at a small part of their original price and the money that is made by selling them is used for a charitable cause.

    The idea of buying used clothes may sound off-putting, but for shoppers who have less spending money, such as the elderly or those in low-paying jobs, it has been a welcome option for years. Now, shopping at charity shops is also becoming popular with young people looking for alternative fashion." You can find very unique clothes for a very cheap price. It doesn't bother me that other people may have worn them. I simply wash them before I wear them," said Anne Marie, a 19-year-old Internet user from the US, in a comment on a Yahoo forum.

    So next time you spot a charity shop, why not go inside? Who knows, you might find a lovely dress for just a few pounds. Even better, you can enjoy wearing it in the knowledge that your money helped a good cause.

    Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day's work.

    Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation (放松).

    Ability (能力) to sleep lies largely in habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance (避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.

    A bath at bedtime, neither hot nor cool but of body temperature may be helpful to sleep. Sleep-producing drug (药) should never be taken except when suggested by a doctor.

    The loud continuous noise of the cars or the sound of a plane can force its way into the deepest forest, yet it's not only humans that ere bothered by the noise.

    Bioacoustician Bernie Krause has been studying the effect of noise pollution on wildlife, and has come across some interesting behaviors, especially among animals that communicate by vocalization（发声）, like humans. Birds use sound to communicate, but in noisy places, these animals have to shout over the natural noise to be heard.

    Krause mentions a study of nightingales to clarify what he means. The birds responded to traffic noise by singing louder and louder until they actually went beyond noise pollution standards in the city. To belt out (sing loudly) their songs, they increased their lung pressure fivefold, but scientists state that this is not dangerous for the birds themselves.

    Studies show that sudden noise can cause certain birds to leave their nests, exposing the young to their enemies. One study also showed that songbirds that nested close to busy motorways were much less productive than those that nested farther away. Mammals（哺乳动物）too are affected. A recent study showed that nursing caribou responded to plane noise by not producing enough milk to feed their young.

    In some cases noise pollution can actually help some animals while harming others. Toads（蟾蜍）and frogs are known to vocalize in synchrony（同步；同步方式）so that no predator (their enemies) can zero in on them. Krause found that when planes flew overhead and disturbed the toad's song, they lost their synchronicity, and it took them 45 minutes to get it back again. That gave their natural enemies plenty of time to find and catch individual toads by sound.

    According to Kruse, “Not only will noise pollution bother wildlife, but it won't help our lives either.”

    Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.

    Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.

    65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven litres of water every day, but we need not drink this amount because a lot comes from the food we have. If we don't have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cold water!

    Many people prefer eating out instead of cooking at home. A change appears to be taking place, though, and millennials are leading the way. According to one survey, more young people are starting to cook at home for three basic reasons: They can save money, eat healthy and waste less food.

    Popular TV chefs are also getting millennials excited about learning some basic cooking skills. Many millennials view cooking as a form of entertainment and self-expression. They proudly post pictures of their cooking creations on Facebook or Instagram, and invite friends over to share the cooking experience.

    Many millennials have also found ways to avoid wasting food. After roasting a chicken, they put the leftover bones in their freezer instead of the garbage can. Later, they use the bones to make chicken stock which is an important ingredient in many dishes.

    They also hate throwing out fruit that's too old. To avoid that situation, they bake ripe fruit like berries and bananas for 15 minutes at 175 degrees C. Then they freeze it overnight. After that, they place the fruit in plastic bags and store it their freezer for later use.

    Now any millennials only eat at restaurants that have excellent food-waste policies. These servants use every part of the vegetables they buy, including their stems and roots, in dishes. They also use beef, chicken and pork bones to make their own stock.

    Millennials also reduce food waste by only buying what they require. Before going to a market, they write down what they need and don't buy anything else. They say they won't purchase more food than they can consume.

    Carrots are grown on farms and in family gardens throughout the world. Carrots are easy to raise and easy to harvest. They taste good.

    When people think of carrots, they usually picture in their minds a vegetable that is long, thin and orange in colour. But carrots come in many different sizes and shapes. And not all carrots are orange. For the best results, carrots should be grown in sandy soil that does not hold water for a long time. The soil also should have no rocks. To prepare your carrot garden, dig up the soil, loosen it and turn it over. Then, mix in some plant material or animal fertilizer. Weather, soil conditions and age will affect the way carrots taste. Experts say warm days, cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.

    Carrots need time to develop their full sugar content. This gives them their taste. But carrots loose their sweetness if you wait too long to remove them from the ground. The best way to judge if a carrot is ready to be harvested is by its colour. Usually, the brighter the colour, the better the taste.

    Carrots are prepared and eaten in many different ways. They are cut in thin pieces and added to other vegetables. They are cooked by themselves or added to stews. Or, once they are washed, they are eaten just as they come out of the ground.
