Anger is not wrong.I know this statement seems shocking and challenges the wildly popular “Positive Thinking” movement，which encourages us to “be full of positive energy” and “let go of our anger”. However，the truth is that anger is just an emotion，and emotions are neither right nor wrong.We do not consciously choose them.We do，on the other hand，choose how we express our emotions and there are definitely right and wrong means of expression.

     The reason we're often urged to “keep_a_lid_on”our anger is that few people ever learn proper and positive ways to express anger.Instead，we are taught that “anger is wrong” and “you should keep your anger inside”．But these messages don't change the fact that，for most of us，anger exists.

     Many popular “Positive Thinking” programmes assume that success comes from “controlling our emotion” and that this can be done by simply repeating positive statements.Interestingly，these positive slogans often include a lot of negativity.“Only losers complain！I am a winner！” is one popular saying.The belief that those who disagree with us are losers is actually quite negative and is often used as an excuse for rude language and personal attacks.

     When it comes to dealing with negative situations in our daily lives，the ability to reasonably express anger or disagreement is an important skill.But we must use balanced and non­violent methods to express our dissatisfaction.Frustration at unfair policies or treatment can certainly cause anger，but our anger can never be an excuse for abusing family members，damaging schools，attacking doctors or most seriously，engaging in terrorism.

     Instead of pretending that anger doesn't exist，we should start teaching appropriate means of dealing with anger.When we experience anger feelings in ourselves or others，what we should “let go of” is the silly idea that we can remove anger with just a few sweet words.Instead，we should find reasonable solutions to the causes of those angry feelings.We need to accept anger as a natural emotion but stop using it as an excuse for violent and destructive behavior.Anger isn't wrong，but failure to deal with it appropriately is.

    There has been an outpouring of love for a 23-year-old disabled woman whose dog was killed in front of her while a groomer(美容师) tried to trim(修剪) its claws.

    Calls and e-mails came from as far away as the Upper Peninsula and Arizona as well as Oakland and Macomb counties, offering Laurie Crouch, who uses a wheelchair because of multiple sclerosis(硬化症), everything from dogs to money, such as that from Jason Daly of Roseville who said, “ I would like to buy her a new dog.”

    A story about the death of Crouch's pet, Gooch, was printed on the front page of Macomb Daily. Crouch said a man sat on the dog to trim its nails. Gooch died after one claw was trimmed.

    Crouch yelled at the groomer to stop when she saw Gooch was struggling to breathe, but she said she was ignored. “If I could have walked, I would have put my hands on her and pulled her off my dog and physically stopped her, but I can't do that.” Gooch was not a trained service animal, but naturally helped Crouch by picking up things for her.

    “This case is absolute animal abuse(虐待),” Larry Obrecht, division manager of the Oakland County Animal Shelter in Auburn Hills, said.

    People who read the story contacted Oakland Press to offer help. A message, from Rebecca Amett of Giggles N Wiggles Puppy Rescue, in Roseville, said, “We have puppies to donate … and want to help the young woman who lost her service dog.”

    “When Gooch was with me, I was happy,” Crouch said, “I think I can be happy again but no animal can replace Gooch. There's never going to be another Gooch out there but I think I will find a dog that can bring me joy again.”

    Did you know that sixty percent of your body weight is water? However, a loss of only two percent of this water through dehydration (脱水) during exercise can significantly affect your performance. The more you sweat, the more your exercise performance declines, unless you drink enough to replace your loss of fluids (液体).

    When you lose too much water, you can overheat quite easily, especially in a warm environment. But this is not the only problem you may face. Dehydration leads to your heart pumping much faster, which means exercise becomes more difficult and requires more effort. Despite these problems, however, many of us simply do not take enough fluids in when we head for the gym or set out on a run.

    So why is this? How do we manage to lose so much water without simply drinking more to replace it? Well, it's easier than you think. When we are at rest, we quickly become aware that we are thirsty and will put that right by having a drink. When we exercise, on the other hand, our thirst mechanism (结构) does not work as effectively, so we don't notice early enough that we are actually thirsty. In fact, we only start to fed thirsty when we have already lost around two percent of our body weight.

    Another problem is that, the more dehydration we become during exercise, the more difficult it is to prevent further dehydration-because our stomachs become intolerant (不能容忍的) to fluids and we do not absorb water properly, just when we need it most.

    The key thing about fluids and exercise is to manage your intake properly-regular small amounts are preferable, and some should be drunk before the period of exercise begins. You also need to match your intake to the sort of exercise you are doing. For example, for one hour of exercise, such as taking part in a 10 km run, you need to drink about two extra litres of water. For longer periods of exercise, sports drinks are recommended.

    Often people receive a guitar, mandolin, or some other musical instrument as a birthday or Christmas gift. There's joy everywhere. The giver of the gift knows how much the receiver wants to learn this instrument and the receiver is actually holding it in his hands instead of longing for it through the shop window.

    Finding an instructor that fits into a busy work schedule is hard enough, but once you decide on a lesson plan, then you must consider the practice time, how to practice, what to practice—and let's face it...not all people learn something the same way. So in order to learn a musical instrument, how much practice time is enough and what kind of practice is right for you?

    There is no set amount of time that anyone should practice a musical instrument. When I was in programming classes, I could have studied nightly for 5 hours each night. It would have taken me years to learn the art of computer programming. Though I'm attracted by the systematic logic of it, my talent is towards another thing. However, on the other hand, if I spent an hour every couple days with a passionate hobby like playing the violin, not only would the time fly quickly...I'd also be learning at a much greater speed since the built-in passion is the motivation for advancement.

    So as much as it's important to practice, a step back is to first find the harmonious instrument that fits you as a person; as development of your personality. If you're learning the guitar because it's cool....obviously that's the modern-day mindset, however, you might not be actually linking your talent for musical satisfaction with your most creative advantages you have to offer.

    It's been my experience that every person has a certain level of musical talent. My pleasant challenge has been to assist them in this adventure and actually locate their best abilities as quickly as possible. Then and only then can we match learners with instruments and truly begin a fun and exciting walk down the road of happiness and contentment, where music, ability, personality and soul all meet. Once this piece of the mystery puzzle is in place, I've never had to work at motivating a learner to practice...

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.

    Do you know of anyone who uses the truth to deceive(欺骗)?When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.

    For example, someone might say,“I just won a hundred dollars on the lottery(彩票).It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”

    This guy's a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He's really a big loser!

    He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest.

    Some politicians often use this trick. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says,“During Governor Smith's term, the state lost one million jobs!”That's true. However, an honest statement would have been,“During Governor Smith's term ,the state had a net gain of two million jobs.”

    Advertisers will sometimes use half-truths. It's against the law to make false statements so they try to mislead you with the truth. An advertisement might say,“Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

    This kind of deception happens too often. It's a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
