Man has been to the moon. It has been the first step towards future exploration in space. When compared with the distances between Earth and the other planets, the distance between the Moon and Earth is very short indeed. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next step. Such travels will be more challenging than the trip to the moon and certainly more exciting and dangerous. Recently, two American spaceships, Viking 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither been confirmed nor ruled out (排除). Russians have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the Earth's atmosphere. Scientists believe man may find planets which have the same conditions as those we have on Earth, but man should realize Earth will be his only home for a long time and begin to love and care for it.

    Teenagers like watching TV, but their weight problem is becoming more and more serious. Sports shoes that work out whether their owner has done enough exercise to assure time in front of the television have been designed in the UK.

    The shoes named Square Eves contain an electronic pressure sensor and a tiny computer chip to record how many steps the weather has taken in a day. A wireless transmitter (发射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day's efforts.

    The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. We looked at current issues and childhood overweight really stood out,” she says. "And I wanted to deal with that with my design.”

    Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

    Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.

    Existing pedometer (计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”

    Leadership today is not about forcing others to do things. If this is even possible, it is short-term. If you order someone to do something against their will, they may do it because they feel they must, but the anger they feel will do more harm in the long-term. They will also experience fear.

    Fear causes the thinking brain to shut down, making the person unable to function at his or her best. If they connect you with this emotion of fear, they will become less functional around you, and you will have succeeded in not only shooting yourself in the foot, but possibly making a very good employee or partner unable to perform effectively. Fear has no place in leadership.

    The way we affect people in a lasting way is by our own character, and our understanding and use of emotion. We can order someone to do something, which may be part of the work day, or we can employ them at the emotional level, so they become fully devoted to the projects and provide some of their own motivation（积极性）.

    Today's work place is all about relationships. Anyone works harder in a positive environment in which they're recognized and valued as a human being as well as a worker. Everyone produces just a bit more for someone they like. Leaders understand the way things work. They know money is not the only most motivating factor in the work life of most people.

    The true strength of leadership is an inner strength that comes from the confidence of Emotional Intelligence-knowing your own emotions, and how to deal with them and those of others. Developing your emotional intelligence is the best thing you can do if you want to develop your relationships with people around you, which is the key to the leadership skills.

    While most people have the idea that volcano eruptions are one of the most destructive disasters in nature, seeing a volcano erupt is a wonderful experience, and you can really feel the heat by climbing to the summit of Pacaya for a close-up view.

    There are guided tours every day up this highly active volcano from Antigua, giving travelers a chance to see Mother Nature at her most powerful. Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won't miss the Pacaya-tour companies.

    But climbing Pacaya is no easy job: it is 2,560 meters high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb you hear the dull sounds of eruptions high above. Steaming, hot remains from recent eruptions begin to line the path as you near the active summit: the Mckenney Cone (火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.

    Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full contrast between the erupting red lava(岩浆) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot steams up to 100 meters into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down.

Best Ways to Quit Smoking

    Not sure how to quit smoking cigarettes? Try the following ways to stop smoking and start your path towards a healthier, smoke-free life.

    Post this list in a visible location in your house.

    Whenever you're tempted to light up, take a look at all the ways smoking can damage your health:

    Increases risk of heart disease, stroke, high blood pressure.

    Reduces levels of folate, low levels of which can increase the risk of heart disease, depression, and Alzheimer's disease.

    Affects mental capacity and memory.

    Contributes to thin bones.

    Affects ability to smell and taste.

    Increases risk of depression in adolescents.

    To minimize cravings (欲望), change your routine.

    Sit in a different chair at breakfast or take a different route to work. If you usually have a drink and cigarette after work, change that to a walk. If you're used to a smoke with your morning coffee, switch to tea, or stop at Starbucks for a cup of java—the chain is smoke-free. You might even work better in coffee shops！

    Tell your friends, coworkers, boss, partner, and kids how you feel.

    Don't bottle up your emotions. If something makes you angry, express it instead of hiding it with cigarette smoke. If you're bored, admit to yourself that you're bored and find something energetic to do instead of lighting up.

    Make an appointment with an acupuncturist (针灸师).

    There's some evidence that auricular acupuncture (i. e., needles in the ears) controls cigarette cravings quite successfully. You can even do it yourself by taping "seeds" (small beads) onto the acupuncture points and squeezing them whenever cravings arise. Acupuncture can treat these other conditions, too.
