Sunstroke (中暑) is a condition that can quickly go from dangerous to deadly, especially if proper care isn't given immediately.

    Sunstroke, sometimes called heatstroke, is a result of the body temperature rising above safe limits. This causes the body's necessary functions to stop working.

    It's usually pretty easy to avoid sunstroke, as long as proper action is taken. In that case, you need to act as quickly as possible to return that person's body to a safe temperature. Here are a few tips to help treat sunstroke.

Call for help

    Call to get an ambulance as quickly as possible. This should be the first thing you do, especially if the sunstroke person has fainted(昏倒). Also, call for help from anyone nearby if you're in a public place. If there's no one around, call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible, if there isn't much nearby.

Get the person to a cooler area

    If there's a building nearby, aim for that. Anywhere with plenty of air conditionings and water is perfect. If a building isn't available, bring the person to a well shaded area.

Get the water flowing

    If the person is still conscious, get him or her to drink water. If there's a bathtub available，fill it with cool water and put the person in it.

If your water supply is limited, you have to save it. Dampen a towel or shirt and put it on the person's body. Focus on the face, neck，and chest.

Fan the person

    Getting moving air over the person cools him or her down. Use anything, a towel or sheet, a shirt your hands，or a piece of board. This is where having many people around really helps, as they can combine to fan the entire body.

    Experts say moods are feelings that tend to become fixed, influencing one's outlook for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.

    Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（药理学）offers a lot of tranquilizers（镇静剂）. What many people don't realize, however, is that scientists have discovered the effectiveness of several non – drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don't head for the drug – store but try the following methods.

    Of all the mood – altering self – help techniques, aerobic exercise（有氧运动）seems to be the most efficient cure for a bad mood. "If you could keep up the exercise you'd be in high spirits," says Kathryn Lance, author of Running for Health and Beauty.

    Researchers have explained biochemical and various other changes that make exercise compare favorable to drugs as a mood raiser. Physical work such as housework, however, does little. The key is aerobic exercise —running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body's use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.

    A new family moved in next door and I got to meet the mother of the family, Lydia. Lydia is Korean, and her family moved to our city so her husband could go to graduate school. We started talking, and she was apologetic about how bad her English was, but I didn't care. I knew how hard it was to learn a second language. I enjoyed chatting with Lydia as we watched our kids play.

    It was what came next that challenged me: Lydia asked if I'd be willing to help her with her English. Now, I am not a teacher. I admire teachers, and I'm grateful for teachers, and it's because I admire what they do so much that I was very very sure that I couldn't do it myself.

    But Lydia was sure that she wanted my help. I was doubtful. I wasn't sure my "help" was even worth being called by that name. But because she asked me, I said "yes." And that was the beginning of a friendship. Lydia and I spent afternoons sitting together and reading the newspaper, and as we did, she asked me questions when she had them questions about language, yes, but also questions about the new culture she found herself in. In turn, I asked my own questions, growing curious about her home country and culture. We bonded over our shared faith and our struggles as mothers of kids with special needs, When I complimented（恭维） her cooking, she began to teach me about Korean food, eventually leading to a shared trip to explore the Korean grocery stores in our city. Because of Lydia, 1 learned more about my own hometown than I ever could have learned by myself. I'm still not sure that I'm any good as a teacher. But I'm grateful I said "yes" when my neighbor asked me to help her with her English. That meant spending extra time with my neighbor, and that extra time meant she didn't remain just my neighbor. She became my friend.

    Homesick is a compound word made up of HOME and SICK. You know what each word means on its own, of course. But think about what the words mean when they are used together. Homesick means SICK FOR HOME.

    Now think for a minute about SEASICK. If you change the word home in the definition(释义)to the word sea, would the definition fit SEASICK? Seasick means SICK BY THE MOVEMENT ON THE SEA. When you are homesick, the only place you want to be is at home. When you are seasick, the last place you want to be is at sea.

    Have you ever heard of a person being heartsick? Heartsick doesn't mean that something is wrong with a person's heart, people are heartsick when they are hurt deep inside and when they feel as if their hearts are broken.

    But, on the other hand, we have such compound words as handshake, handstand, and handbag. Perhaps you may write definitions for them.

    Triple Olympic and world sprint(短跑) champion Usain Bolt of Jamaica said on Monday he expects years of fast feats to ease doping doubts in athletics and has no plans to play American football.

    Appearing on ESPN programs and in light-hearted races outside the television sport network's studios, Bolt said he feels he must prove himself to a skeptical sports world in the wake of past doping scandals(诽谤).

    "I have to prove myself to the world that you can run fast without it," Bolt said.

    Bolt cited the speeds he and countryman Asafa Powell and American Tyson Gay have achieved without positive doping tests.

    "We just (have to) continue to run fast," Bolt said. "In a couple of years everyone will continue to watch again and have less doubts."

    Bolt won gold in the 100m, 200 and 4x100 relay in world record times at last year's Beijing Olympics and last month in Berlin set world records of 9.58 seconds in the 100 and 19.19 in the 200 and helped a relay title in a World Championships treble.

    "I want to be a legend in the sport. For me it's all a focus on winning championships after championships," Bolt said.

    "I don't consider myself a legend. When I defend my titles I will consider myself a legend."

    Bolt's defending of World and Olympic gold should be the feature attraction of the 2011 IAAF World Championships in Daegu, South Korea, and the 2012 London Olympics.
