Where is the true home of hamburger?

     The kind of beef we see in hamburgers , minced(切碎)beef, was possibly invented by Mongolians over 800 years ago. But who first put the beef between pieces of bread and called it a hamburger? Three different cities in the United States all say that they were the first to invent America's favorite food.

     Some people say that Fletcher Davis, from Athens, invented hamburgers. “Old Dave,”as people called him, was selling minced beef sandwiches in his lunch bar as early as the 1880s. Some years later, they say that a group of Germans called①his sandwich a “hamburger” because people from the German city of Hamburger ate this kind of beef.

     Other people believe that the hamburger came from a different American city.②coincidentally, its name was also Hamburg. The Menches brothers were selling pork sandwiches at a fair in 1885, but when there was no more pork, they used minced beef and gave it a new name, the “hamburger”.

     The third possible inventor of the hamburger was Charlie Nagreen, also known as “Hamburger Charlie,”from Seymour. He said that in 1885 he invented the world's first hamburgers. Seymour now celebrates the invention of the hamburger every year. In 1989, it was the home of the world's largest ever burger—over 2,500kg!

 It's a wonderful, warm summer day without a coud in the sky. You're outside, and you can feel the sun's heat on your skin. Do you know what else you are feeling? You're feeling the sun's energy! Without it, the earth would be a cold, dark, lifeless place The sun's radiation(辐射) gives us light and heat energy.

 The Sun's radiation can be harmful to us as well. We can't see it, but ultraviolet(紫外线) radiation comes from the sun along with heat and light. You can not see ultraviolet radiation, but it influences our health. Ultraviolet radiation is what burns our skin.

 Ultraviolet radiation has three parts: ultraviolet radiation A, ultraviolet radialion B, and ultraviolet radialion C. Waves of ultraviolet radiation  A and B may cause harm to our body when we get sunburned. The harm to our body can give us skin cancer(皮肤癌) and cause other health problems.

 You can help to protect yourself from ultraviolet radiation by wearing sunscreen(防晒霜), sunglasses and hats.

 Try to stay out of the sun when it is especially strong .You can find out ultraviolet radiation levels by watching the weather report on television.
