In 1901, an Austrian scientist discovered that there are four types of blood. He named them A、B、AB and O. People have one of these four types. Blood type O is the most common around the world. Blood type A is the second most common, and blood type AB is the least common.

    In 1927, a Japanese doctor found that people with different blood types have different personalities (性格)，too. He said that people with type A blood are usually calm and serious; people with type B blood are cheerful and outgoing; people with type O blood are generous and honest; while those with type AB blood are often caring and talented.

    More recently, a doctor in the United States wrote a book that connects blood types with what people eat. The book suggests people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book, Eat Right for Your Type, has been a hit with people who want to lose weight. However, Dr. Peter D' Adamo believes that eating food that matches a person's blood type will make the person healthier in other ways, too.

    Members of an international organization are called the Global Greeters. They offer travelers the chance to get to know a city as well as local people do.

    Unlike the professional guides(专业导游), the volunteer greeters act more like neighbours. They take visitors to visit the city–either on foot or public traffic—to discover favourite neighbourhoods, cafes and parks.

    All the programs work a little differently, but the basics(基本项目) are the same. The tours are free and last anywhere for two or four hours. Volunteers can be all ages, and their ages and interests try to match the travelers.

    New York City(USA)

    Big Apple Greeter is the pioneer “welcome visitor” program founded in 1992 by New Yorker Lynn Brooks. More than 300 volunteers now can welcome guests from all over the world in 22 languages. Greeters explain the New York City subway and bus systems and show guests around one or more of their favourite neighbourhoods. Like many greeter organizations, Big Apple accepts online donations to help with its daily costs.

    Houston(USA)

    Houston Greeters will organize activities such as golf, biking or an outing to an Astros game(太空人队的比赛). Another activity is to arrange a tour in need of a particular interest.

    Chicago(USA)

    Chicago Greeters help visitors visit one of the city's many famous neighbourhoods. The group organizes walks through Ukrainian Village on the Near North Side and Andersonville, home to Scandinavian restaurants and shops and Middle Eastern bakeries. Guides will also organize tours around themes such as fashion, film or public art.

    France

    In France, English speaking volunteers for Parisien d'un Jour lead visitors through hidden corners of Paris, often ending with a lively discussion on a café balcony. Guides in Lyon organize walks around themes such as shopping, markets and sports.

    Each summer, you hear news that some sports players are sent to hospitals because it is too hot. Our bodies can't be outside in the sun for a long time. So in hot summers, be careful about playing sports outside.

    Firstly, to play sports safely in hot weather, you must drink water. Sports drinks are great for athletes, but they have so much sugar that they'll dehydrate（使脱水）you more. However, drinking afew bottles of sports drinks will be good for you.

    Secondly, be sure to take enough breaks to let your body rest. If your coach doesn't let you do so in the heat, don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks.

    Thirdly, when you have a break, don't sit in the sun. With the sun beating down on you, you'll only heat up and sweat（冒汗）more. Take a seat under a tree, or even better, go indoors for a little while.

    Cooling yourself down can help you stay active longer.

    Fourthly, remember that the earlier in the day you start your exercise, the cooler it will be. If you can start practice before the sun comes up, you have a few good hours to practice in the cool hours of the morning. Also, the earlier you practice, the earlier you can finish the exercise. If you need more practice time, come back to the field later in the evening when the sun is setting.

Last but not least, you should watch your food. Eat food which is high in water, starch（淀粉）and carbohydrate(糖类), but be sure to get a good balance in your diet.

    As long as you pay attention to the above, playing sports safely in the heat isn't a difficult thing.
