In Japan, most Christmas trees are made of plastic. In the U.S., there are many artificial trees, but there are also many real trees. You can buy them at Christmas tree lots. A real tree cost about 50 dollars in 2015. An artificial tree cost a little more. Which is better, a real one or an artificial one? That depends. You can reuse artificial trees, but you have to throw away real ones. Real ones smell good, but plastic trees don’t have any smell. Real trees don’t use plastic, so they are probably better for the environment. If I lived in the U.S., I would buy a real tree. (by Douglas Jarrell)

How do people keep warm in winter? Many people wear coats, but coats can be inconvenient when you travel by car. You have to take them off when you get in and put them on again when you get out. That’s why many businessmen wear vests under their suit jackets. These days, there are thin vests that are very warm because they are made of down (duck feathers). There is also electric clothing for people who are active outdoors. I met someone who was wearing an electric top (like a thin sweater). It was powered with a battery. He really liked it because it kept him very warm. (by Douglas Jarrell)
