Everyone can benefit from better communication. {#blank#}1{#/blank#}Of course, we know that isn't true, but this shouldn't stop you improving your communication skills. Here are a few tips to help you become a better communicator.

    {#blank#}2{#/blank#}

    Verbal (口头的) language is only one part of the communication — body language is another. If you ever wanted to know how to tell if someone is lying, body language is the answer. Your body language tells other people what you aren't verbally saying, such as if you are anxious, confident, confused, angry or any other type of emotion or state of mind. If you become great at reading body language, it will help you become a better communicator.

    Listen to others

    Before you ever begin to speak, take a minute to see if anyone else has something to say. {#blank#}3{#/blank#} Listening to others has many benefits, such as allowing you to learn new things or get information that you may later need.

    Think before you speak

    Your parents probably told you this as a child, but many people still do not take a moment to think about the words they are about to say. {#blank#}4{#/blank#} There is a time and place for all words and tones of voice.

{#blank#}5{#/blank#} You will have to practice your communication skills before you can ever become an excellent communicator.

A. To become a better communicator is not an overnight thing.

B. Singing a song for them is good.

C. Become fluent in body language.

D. Don't try to make the conversation go your way.

E. You should decide what you want to get in a conversation before you choose your words.

F. If you are too anxious, you can't look for the right body language to use in communication.

G. In fact, if everybody were excellent communicators, the world would be a much better place.

    It isn't often that zookeepers call on craftsman for help. But cold weather at the Wildlife SOS Elephant Conservation and Care Center in northern India was putting elephants at risk. So the center's staff joined forces with locals to find a creative way to keep the animals warm. Now the elephants are stepping out in style, thanks to volunteers who made use of their crafting talents to knit (编织) enormous sweaters to protect the animals.

    Wildlife SOS is a conservation group that has been taking action against animal cruelty and saving wildlife in danger since 1995. Their Elephant Conservation and Care Center is devoted to rescuing the large animals from abuse in circuses, illegal dealing, and other circumstances where they have been ignored or treated with extreme cruelty. There are currently 20 elephants living at the center, and the staff hope to take in 50 more of the creatures this year.

    Because most of the elephants housed at the center are recovering from injuries or are elderly and weak, they are particularly vulnerable to cold temperatures. When the staff reported near-freezing nighttime temperatures in the winter, volunteers from surrounding villages began knitting enormous sweaters to keep the elephants warm. The monumental sweaters are large enough to cover the elephants' backs, bellies, and legs.

    Making the sweaters is a big undertaking—each one takes approximately four weeks to create, with volunteers working together on the enormous clothes. Local villagers have already made sweaters for three of the 23 elephants on their own, each with a unique pattern and color.

    If you're also looking for something happy and heartwarming, this is it. The elephants usually wear blankets to keep warm during colder months and you can purchase a blanket for an elephant on the Wildlife SOS website.

    We all know the feeling: looking at the computer screen, pretending to be interested in our homework, even though we really feel bored. But such feelings may soon be at an end, says Dr. Harry Witchel, head of the Essex Medical School. He believes that computers of the future will notice when people feel bored and even take action to stopit.

    Before you get concerned, the machine won't be reading your mind. It will be observing the many movements you make while using a computer. It's not interested in the big movements needed to use the machine — like moving a mouse or touching a screen — but small, barely noticeable movements like closing your eyes, moving in your seat or rubbing your face. Witchel calls these “boredom movements" and says they show how interested the person is in what they are reading or watching. The higher the interest level, the less movement!

    To test his theory, Witchel invited 27 people to perform various computer-based tasks. The activities ranged from playing online games (an interesting task) to reading documents like government laws that most people would find boring.

A special video camera followed the participants' movements as they completed each task. Just as the researcher expected, the “boredom movements" greatly decreased, by as much as 42%，when the subjects were very interested in what they were reading or seeing.

    Fortunately, Dr Witchel isn't planning to use his results to create machines that report students who are not paying attention at school. Instead, he wants “movement sensing” technology to be built into future computers in order to improve students' computer-based learning experience.

    The scientist says that by measuring the students' interest level as they work, educators will be able to adjust their materials in real-time to keep students focused. Witchel also believes that the technology can provide filmmakers with honest audience opinions and in the future, help to develop more intelligent robots.

    Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate  (迁徙) north.

    Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.

    According to Science Daily, a new study predicts that by the year 2100, many of today's familiar climates will be replaced by climates unknown in today's world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.

    Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn't matter what is causing it, but rather, what can be done about it. What's more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.

    However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.

    Sitting has been called the new smoking for its supposed Public health risks, especially for people with sitting down office jobs. Over the past 15 years or so sitting has been connected with heart disease and diabetes (糖尿病). But is sitting really that risky?

    In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.

    We studied sitting habits of 4. 811 middle-aged people, who didn't have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetes.

    This is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.

    For people who are physically inactive, though, the story's different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obese.

    That's not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.

    For example, sitting down at work isn't strongly connected with long-term health risks, Perhaps that's because higher position jobs needs more sitting, and higher socioeconomic (社会经济) position is connected with a lower risk of disease. It's a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to (a) be of lower socioeconomic positions, unemployed, have poorer mental (精神上的) health, eat unhealthy foods and face more unhealthy food advertising.
