    Peels can be there for you in ways that people can't．They can offer love and companionship, and can also enjoy comfortable silence, keep secrets and are excellent companions．And they could be the best killer to loneliness．In fact, research shows that nursing home residents reported less loneliness when visited by dogs than when they spent time with other people !  All these benefits can reduce the amount of stress people experience in response to feelings of social isolation and lack of social support from people．

    Some people have the feeling that nothing can be done about their poor reading ability（能力）.They feel hopeless about it.Can you learn to read better,or must you agree that nothing can be done about it?

    To be sure,people are different.You cannot expect to do everything as well as certain other people do.If all the students in a class tried out for basketball,some would be very good players,others would be very poor;and many would be in between.But even the very poor players can become much better players if they are guided in the right way,and with plenty of practice.It is the same with reading.Some seem to enjoy reading and to read well without any special help.Others find reading a slow and tiring job.In between,there are all degrees of reading ability.

    Many experiments have shown that just about every poor reader can improve his reading ability.In these experiments,the poor readers were given tests of reading ability.After some of the causes of their poor reading were discovered,they were given special instruction and practice in reading.After a few months,another test of the same kind was given.In nearly all cases,these people had raised their reading scores.

    Do you have cold feet in winter? But now if you wear a pair of Ugg boots, you won't be troubled by that.

    UGG means Australian Sheepskin Boots. UGG boots became popular among shearers(剪羊毛的人）in the 1920s. The shearers sheared the sheep and grabbed a bit of dead sheep, wrapped it around their feet and called them “Ugly Boots”. Good old Australian slang shortened Shearers Ugly Boots to UGG boots. Thus UGG Boots date back as far as the 1920s in Australia.

    Ugg boots became so popular because of the amazing amount of comfort they bring to the feel. The sheepskin is made incredibly soft so the boots are warm and comfortable. Ugg boots fed more like socks than shoes, yet they are tough enough for outdoor wear. The unique, wool fool-beds lake the shape of the natural edge of each wearer's feet, creating personalized arch (弓形) supports.

    Our ugg boots are handmade with Australian sheepskin of the highest quality by our factory of Ugg Original Pty Ltd.

    We can also wear ugg boots in cold weather or summer. In cold weather, the thick wool of ugg boots provides a preventing layer of warmth by trapping your body heat. In the heat of summer, the natural fibres of the wool will actually cool your feet by absorbing sweat. Ugg boots are made to be worn barefoot to maximize the cushioning and warmth provided by the sheepskin.

    Kung fu is one of a number of Chinese martial arts designed to improve the body and the mind. It is perhaps one of the most widely known martial arts, because many films include its techniques. There are hundreds of styles taught all over the world, although they can be loosely divided into two camps: Shaolin style kung fu, and other techniques, some of which have a history that outdates the Shaolin order.

    Shaolin kung fix has its origins in the fifth century. Like some other martial arts, it began in religious temples, where the monks sought a mind and body discipline (训练方法). In addition to the fighting style, it also includes mental exercises and religious practices designed to balance the whole body.

    Shaolin temples resembled universities, integrating a wide range of subjects of study. Therefore, traditional Shaolin styles such as Wing Chun, Crane, Praying Mantis, and Hung Gar took knowledge from fields outside martial arts, such as the healing arts and meditation. Supporters for Shaolin styles believe that they are more rounded martial arts styles, and that learners will benefit from them on a whole body level.

    Other fighting styles, some of which predate the Shaolin style, are also lumped under the kung fu umbrella. They include Pa-Kua, Eagle Claw, and Eight Drunken Immortals styles. These disciplines are not considered to be Shaolin style because they did not originate in temples and are focused primarily on fighting techniques.

    Whether Shaolin or otherwise, kung fu is characterized by self defense strategies that turn the energy of an attacker against him or her. Although the techniques may vary, most styles teach throws, kicks, punches, and the use of weapons. In addition to the physical discipline, most place a great importance on respect, honor, and living a balanced life.

    Dogs certainly need to bark (犬吠) every now and then, but if your neighbor's dog is getting in the way of your daily life, you need to do something.

    "Before you take action, you should record the dates and times that the barking happens to find out any patterns," says Schweitzer, who is a dog owner. You might notice the barking only happens when the owners are at work, or during thunderstorms.

    After two to three weeks of observing (观察), go to your neighbors with the facts. Wait for a time when the barking is over. "Since you're trying to keep a good relationship, you can't go when you're angry and upset," says Schweitzer. Besides, your neighbors might not even realize the barks are a problem, especially if the worst barking happens when they're not at home.

    Politely explain the times when the barking gets bad, and then suggest a way of solving the problem. Ask if the dog can stay inside during storms, or offer a dog training class.

    Making friends with the dog could help you gain some peace and quiet. If your neighbors introduce you to their dog, you should give the dog a treat. "If they become more comfortable seeing you, they're less likely to bark when they see you or when they're in the backyard，" says Schweitzer.

    Whatever you do, don't talk with your other neighbors about the problem or start a petition (诉状) to get the dog to quiet down. "Those make people feel angry," says Schweitzer. "That's when things escalate."

    If weeks go by and you still aren't seeing a difference, follow up with a note. Tie a dog treat on the note to build trust with your neighbors, and make a copy before dropping it off. That way, you'll have evidence (证据) that you've discussed it before and followed up politely if you need to bring in a third party, says Schweitzer.

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.
