Many people reported having seen UFOs in the sky. A lot of countries tried to research into them and in 1952 they got the name of UFO. There were several reports published in the 19th century which were related to UFOs. Denison Daily News in its report of 25th January, 1878 wrote that a farmer, Martin saw a flying object in the sky and it was just like a plate. This was the first time that the word plate had been related to the UFO. First reports on UFOs came during World War . In 1947 the pilot Kenneth Arnold said while he was flying near the Mount Rainier he saw a very bright object in the sky. He told that it was like a plate, too. The information given by Kenneth got lots of attention from the media and people. Several research organizations gave their reports on UFOs. They showed direct or indirect physical evidence of UFOs, and sometimes UFOs appearance was found in the radar(雷达) screen. Many peopletry to take videotapes or photos of UFOs as proof. Most UFOs are in plate shape while some UFOs are like cigarettes or half balls. Many films and TV shows are made about UFOs.

Finally, the bell rings and its time for lunch! After class, you should have a chance to go to the dining room and sit down,relax,and enjoy the time with your friends over a lunchtime meal. But wait a minute what exactly are you eating? When choosing what to eat for lunch,making a healthy choice is really important. Eating various healthy foods gives you energy to study,helps you grow the way you should,and can even keep you from getting sick. Think of your school lunch as the fuel(燃料) you put in your car. If you choose the wrong kind of fuel, you might run out of energy before the day is over. Most kids have the choice of packing lunch or buying one at school. The good news is that a kid can get a healthy lunch in either way. Probably, some meals and foods served at school are healthier than others. That doesnt mean you shouldnt buy your lunch. It just means you might want to give the menu a closer look. A packed lunch isnt always healthier than one you buy at school. If you pack chocolate cake and potato chips,thats not a healthy meal! But a packed lunch,if you do it right, does have a clear advantage. When packing your lunch,you can be sure it includes your favourite healthy foods. If your favourite sandwich is peanut butter and banana,just make it and pack itthen you can eat it for lunch. If you want to pack your lunch,youll need some help from your parents. Talk to them about what you like in your lunch so they can stock up on those foods. Parents might offer to pack your lunch for you.
