Every day I pass by a homeless old man on the street. He usually sat near where I go to school. Whenever I pass by, he says “hello” in a cheerful manner, and I always say it back. I give him any extra change I have.

The old man always wears an old watch. It is not an expensive watch by any means, but it serves its purpose. One day I noticed he wasn’t wearing it any more. I asked him why and he looked down and told me that the battery (电池) had died so he threw it away. I knew he couldn’t buy a new battery and he didn’t have enough money to buy a new watch.

He stayed on my mind all day, and I knew what I had to do. I went out to a shop and bought him a watch. It was not an expensive one, but one that was very similar to the one he had.

When I saw him the next day, he was smiling and cheerful as ever. When I bent down to put some change in his cup, I also dropped the watch in. I didn’t say anything about it. I just smiled at him and kept on walking. He didn’t even notice it until I left. I looked back and watched as he pulled the watch from the cup. He looked at me and I just smiled and nodded. He put the watch on with a big smile on his face and I walked happily on my way.

March 16 is International Sleep Day. And we should all celebrate the act of sleeping. Researchers say sleep is probably the best tool we have for memory and learning. But what about getting rest during the middle of the day?

A recent study on napping(小睡) says short periods of sleep may help our brains work better. Past studies have shown that napping can help babies and young children learn better. And napping can help brain performance in older adults. Taking a nap may also help this group of people fight off memory loss because of the increase in their age.

Many Americans do nap. But one-third of all adults in the United States are also chronically(长期的) tired, says the U.S. Centers for Disease Control and Prevention (CDC). It found that 50 million to 70 million Americans have chronic sleep disorders. However, they seem to be unwilling to tell people that they take a nap. They may think that napping shows they are weak or they don’t have enough energy. It is not an uncommon opinion that only children, the very old, sick or lazy people nap. In fact, Americans sometimes do a very strange thing. Some people brag about how few hours of sleep they need each night to show that they are somehow stronger than the average human-superhuman, if you will. However, that may be changing. Many offices now offer napping rooms and napping cafes(咖啡馆) are appearing in many U.S. cities, including Washington, D.C. Remember that an hour long nap may be too long for young, healthy adults. It is Recommended that 30 minutes is enough to remove the pressure(压力) to sleep and will help people feel more awake. If people nap longer, they will get trapped into deep sleep, which can be hard to get out of. If you have trouble falling asleep at night, limit your daytime nap to under 45 minutes. Also nap before 3 p.m.

We all need a healthy environment, but we produce waster every day and it is     81     (harm) to our environment. In fact, we can do something to help.

Reduce means “use less”. Don’t waste things. This saves money and     85     (reduce) pollution. Before we buy something new, think if it is really necessary. When we do buy thing, please     86     (choose) local products (产品) if possible, and try not     87     (buy) too many things from foreign countries.

Reuse means “use again”. When we buy things, make sure that they last a long time. We should take care of them so that they will last.

Recycle means “change things into something else”. Although it takes energy to change something into something else, it’s’ better than     88     (throw) things away or burning them. Find out what can     89     (recycle) in your neighbourhood and take part in recycling programs. We should also buy products     90     (make) from recycled materials.
