    Hello, everyone. It is my honor to be here to talk about my experience of learning English.

    Thank you!

    An international team of researchers found employees who endure what is known as "abusive supervision" are more likely to behave poorly on purpose by messing up tasks, arriving late, taking long breaks and putting in minimal effort.

    The authors of the study, published in the Journal of Management, sought to answer why horrible bosses make employees less willing to show what is known as organizational citizenship behavior (OCB), or commitment to the company outside of their contractual obligations. That could include helping colleagues or volunteering for unusual work hours. They also assessed its effect on a worker's tendency to harm the organization, by displaying counterproductive (反作用的) work behavior (CWB).

    To find out more, and uncover which negative outcome bullying (欺凌) behavior is more likely to cause, researchers from Southwestern University of Finance and Economics in China, Renmin University of China and Swinburne University of Technology in Australia cooperated and analyzed 427 existing studies. They found workers acted out either because they felt they were being treated unfairly in the workplace, or felt stressed and this affected their ability to perform as expected. An employee who felt they were a victim of injustice tended more towards reluctance to show OCB. Stressed workers, meanwhile, were more associated with CWB.

    Employers who worried supervisors are affecting productivity can take steps to ease issues by regularly training managers, introducing policies which cope with workplace injustices and helping workers to deal with stress.

    This is not the first study to suggest unkind practices can affect the well-being of workers. The paper follows a study published in the European Heart Journal last year, which showed employees who suffer bullying are more likely to develop heart diseases than those who aren't. Bullying and violence are common at workplaces and those exposed to these stressors are at higher risk.

    Are you working with your computer routinely either as an office employee or a game lover? Are your eyes dry, watery, blurry, seeing double or sensitive to light? If your answer is a "yes", you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome. What on earth is this syndrome coming from? What can we do to deal with this problem?

    Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists attention during the day but can result in interrupted sleep patterns at night.

    Years of scientific researches indicate that eyestrain isn't necessarily an unavoidable problem for those who deal with computer work in the daily base. There are ways you can adopt which can overcome the problem considerably. To begin with, your computer screen should be high-resolution (高分辨率), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that "computer glasses", which cut down glare and blue light，are available.

    Besides, to reduce your risk for computer-vision syndrome, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, eyestrain are significantly reduced when computer workers take four additional five-minute "mini-breaks" throughout their workday. Finally, many of us fall into bad habits while using digital screens, which only worsen the effects of eyestrain. While viewing digital screens, many people blink (眨眼) one third less often than they usually do. Place a reminder on your computer to "blink" so that your eyes don't dry out.

    It is natural for species of animals to become extinct over millions of years. But over the past 200 years, humans have caused the process to speed up. In recent years, the total number of threatened animal species has increased from 5205 to 5345. In most cases this is a result of human activity. How are people speeding up the process of animal extinction?

    First of all, people threaten the survival of animal species by destroying their habitats. As the human population grows, people keep building houses and factories in fields and woods. As they spread over the land, they destroy animals' homes. If the animals can't find a place to live, they die out. Sixteen kinds of Hawaiian birds have become extinct for this reason.

    Overhunting is another way that humans are causing some animals to become extinct. In some parts of the world, the parts of rare animals are worth a lot of money. For example, some people will pay more than $3,000 for a single rhino horn. This encourages hunters to kill rhinos even though the animal faces extinction.

    Humans are also polluting the air, water and soil. The effect of pollution on animal species can be complicated. For example, when waste from factories is dumped into rivers, the rivers become polluted. The fish that live in the rivers are poisoned, and the birds cannot lay strong eggs. And some, such as brown pelicans, have become rare and may die out.

    Finally, when humans introduce new species into certain environments, the animals that already live there become threatened and face extinction. For example, when European settlers brought rabbits and foxes to Australia, they killed off many native Australian animals, including the bandicoots. Eventually, the rabbits took over the bandicoot habitats. Now bandicoots are threatened with extinction in their own land.
