Jim is an artist and environmentalist who loves animals very much. He often saw 【小题1】 dogs sleeping in some used tires (轮胎). An idea came into his mind, “Why not use these tires to make some comfortable 【小题2】 for the poor dogs?”

After that day, Jim started collecting old tires. He first cleaned them and 【小题3】 their tops. Next, he covered the holes in their bottoms with boards. The artist then painted each tire 【小题4】 bright colors. He also put something soft on the tires in order to make the beds more comfortable. 【小题5】, he gave these colorful beds to local animal houses.
