Watching a sporting event with family and friends under the sun is a great experience in summer. 1. In the United States, heat exposure led to 8,000 deaths between 1979 and 2003. Luckily, a little prevention can go a long way towards making sure of an enjoyable day.
Know the danger
Heat-related illnesses do not require record-breaking temperatures to occur. 2. The body’s temperature can reach 106 or 107 degrees Fahrenheit on a 90-degree day, creating a potentially deadly situation. Factors such as age, weight or a medical condition can influence people.
Drink plenty of water
3. Sweating is your body’s key way to keep cool, so drink water to stay well hydrated(含水的) before you feel thirsty. A cool beer may sound perfect on a hot day, but drink responsibly. Alcohol stops the body’s cooling system and causes you to go to the bathroom frequently.
4.
Wear light-colored and loosely fitting clothing, so air can go around your body and help keep you cool. A hat is a must to help you keep cool, since your head contains many blood vessels(血管), and sun block(防晒乳) is always a good idea.
Take action
What should you do if you are suffering from the heat while watching your favorite event?
Get up and go. It is a simple piece of advice, but could make the difference between a quick recovery and something more severe that requires medical attention. The ideal thing is to move yourself from the position you’re in to an area that is a little cooler. 5.
A. Dress for the occasion
B. Weather-related causes
C. In hot weather, it is essential to stay hydrated.
D. You may miss a little of the action, but it beats missing a lot.
E. But when you add sun exposure to the crowds, the results can be deadly.
F. It is also important to take advantage of services the equipment provides.
G. Temperatures between 80 and 90 degrees Fahrenheit can be dangerous.

Beneath the ocean’s surface, an active world surrounds the globe．A lot of spotted fish swim through coral reefs．
But time is running out for these underwater treasures．Last month, at the National Oceanic and Atmospheric Ad－ministration's coral－reef meeting, researchers warned that 60% of the world's coral could die within the next 25 years．About 27% of the living underwater cities have already been lost．
Though some coral formations are similar to lifeless stone, coral is made up of tiny animals called coral polyps．They grow and divide to build coral colonies．their bones are left behind．New corals grow on top, forming reefs．The complex reef ecosystem covers less than 1％ of the ocean floor, yet supports about 25％ of all marine life．An ecosystem is a partnership between living things and their environment．
The destruction of coral reefs puts many species at risk of extinction．Some researchers say that at least 1 million species of plants and animals live in the world's reefs．On October 29, scientists said they had discovered new reef species in the waters off Hawaii．
Water that is warmer than normal can cause deadly coral bleaching(漂白)．Coral contains tiny algae(藻类)．They give coral its beautiful color．Coral uses the algae to create food and grow．At high temperatures, corals get stressed and release the algae．Without the algae, coral loses its color and starves．The weakened coral becomes more sensitive to sun－light and disease．Last year, warming in the Caribbean Sea bleached more than 90% of the coral on many reefs．
