　　There are several things about motorcycling that the average citizen dislikes. A cyclist's appearance has something to do with this dislike. Motorcyclists frequently look dirty; in fact, they are dirty. On the road there is little to protect them from mud, bird droppings, etc. For practical reasons they often dress in old clothing which looks much less respectable than the clothing of people who ride in cars. For the same reason motorcyclists usually wear dark colors. Perhaps, this helps to explain why they are sometimes believed to have very bad natures. In old plays of long ago, bad characters usually wore black. In cowboy movies the “bad guys ( = fellows)” usually wear black hats while the “good guys” wear lighter colors.

　　Something else about their appearance makes an unpleasant impression. In their practical protective clothing they look very much like the men on military (军事的) motorcycles in the movies of World War Ⅱ - cruel enemies who roared (咆哮) into peaceful villages filling peoples' hearts with fear.

　　Probably the machine itself also produces anger and fear. Motorcycles are noisy, though some big trucks are even noisier. But trucks are big and carry heavy loads; they are accepted because they perform a needed service, making America move. Motorcycles, on the other hand, make an unpleasant noise just to give their riders pleasure. That is what is commonly thought. In the woods motorcycles frighten animals. Roaring along quiet streets, they wake sleeping families and made babies cry.

At present time, roller skating (滑旱冰) is easy and fun. But many years ago, it wasn’t easy at all. Before 1750, people never tried skating on wheels. That changed because of a man named Joseph Merlin. Merlin’s work was making instruments (工具). In his free time he liked to play the violin. Merlin was a man with many ideas and many dreams. People called him a dreamer.
One day Merlin received an invitation to go to an important party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think. He wanted to find a way to make a wonderful entrance at the party. Merlin had an idea. He thought that he would attract a lot of attention if he could skate into the room.
Merlin tried different ways to make himself roll (滚动). Finally, he decided to put two wheels under each shoe. These were the first roller skate shoes. Merlin was very proud of them. He dreamed of arriving at the party and skating into the room while playing the violin. He was sure that everyone would be very surprised.
On the night of the party Merlin rolled into the room, playing his violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop his roller skating. He rolled on, playing the violin. Then, with all eyes on him, Merlin hit into a huge mirror on the wall. The mirror broke into many pieces with a very loud noise.
Nobody forgot Merlin’s wonderful entrance after that.
