Today, roller skating is easy and fun. But a long time ago, it wasn’t easy at all. Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin was a person who liked playing the violin and was full of ideas and dreams. People called him a dreamer.

One day Merlin received an invitation to a fancy dress ball (化装舞会). He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand  entrance at the party. He came up with an idea. He thought everyone would be attracted by him if he could skate into the room.

Merlin tried different ways to make himself roll. Finally, he decided to put two, wheels under each shoe. These were the first rolled skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.

　　On the night of the party Merlin rolled into the room, playing the violin. Everyone was amazed to see this. There was just one problem. Merlin had no way to stop his roller skates. Suddenly he ran into a huge mirror hanging on the wall. It fell down and broke into pieces. Nobody forgot Merlin's entrance for a long time.

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.

　　On one side stand those who see clothes dryers(干衣机) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I-can-do environmentalism(环境保护主义).”

　　On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) across the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.　　

　　So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be more.　　

　　Matt Reck, 37, is the kind of eco-conscious(有生态意识的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighbor had telephoned them about his clothesline. The Recks paid no attention to the warning and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.　　

　　North Carolina lawmakers are saying that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.

　　Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.”

One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ________.

A. clothes dryers are more efficient   

B. clothesline drying reduces home value

C. clothes dryers are energy-saving    

D. clothesline drying is not allowed in most U.S. states

Which of the following best describes Matt Reck?

　　A. He is a kind-hearted man.         B. He is an impolite man.　　

　　C. He is an experienced gardener.    D. He is a man of social responsibility.　　

Who are in favor of clothesline drying?　　

　　A. housing businesses.           B. Environmentalists.　　

　　C. Homeowners Associations.     D. Reck’s dissatisfied neighbors.　　

What is mainly discussed in the text?　　

　　A. Clothesline drying: a way to save energy and money.　　

　　B. Clothesline drying: a lost art rediscovered.　　

　　C. Opposite opinions on clothesline drying.　　

　　D. Different varieties of clotheslines.
