Monkey Light 光る車輪,自転車用 LED ホイール・フラッシュライト;

Have you ever heard of Monkey Lights? They are not lights for monkeys. They are a special product for your bicycle. You put them on the spokes of your bicycle. They use LED lights, so they are very bright and help drivers to see you in the dark. At the same time, they create beautiful patterns on your wheels. I checked the price for these lights online and found that they aren’t very expensive. I may buy them for my bicycle. If you pay more, you can buy a special type that you can program with your computer. You can create almost any image you want. (by Prof. Douglas Jarrell)

These days there are many terrible diseases in the world: AIDS, SARS, Ebola, and MERS. When I was growing up, there was another dangerous disease called smallpox. Every year, it killed about 2 million people. Now, no one has this disease. How was it stopped? Countries around the world worked hard and gave people vaccinations. They were so successful that on October 26, 1977, only one person was found with smallpox. He was the last person who had this disease, and he survived. I hope the world can do the same with other dangerous diseases. (by Prof. Douglas Jarrell)
