People all over the world are trying to save our earth in different ways. For example, they set some special days like Meatout Day, Earth Day, Buy Nothing Day and so on. Meatout Day is on March 20th. On that day, people around the world don’t eat any meat. People agree that eating less meat makes them healthy. Also, they don’t kill any animals for meat on this day. Earth Day is on April 22nd. On this day, people usually try to do something green. For example, people in Italy don’t use plastic bags. When they go shopping, they take their own bags from home. In Canada and Norway, people ride bicycles instead of using their cars. In the USA, people dress up like plants or animals and dance in Times Square, New York. Buy Nothing Day is usually on the fourth Friday in November. On this day, many people don’t buy anything. “Buy Nothing” means making no litter. When we make less litter, we can help make a clean earth. 15.What don’t people do on Meatout Day? _____________________________________________________ 16.How many special days does the passage tell us? _____________________________________________________ 17.How do people in Canada usually go to work on Earth Day? _____________________________________________________ 18.What does “Buy Nothing” mean? _____________________________________________________ 19.What do you usually do to help save the earth?
