单选题 Cirque du Soleil (say it: Serk du So-lay) is being accused of out-dated thinking about the dangers of AIDS. It is a modem acrobatic circus from Canada that tours in the United States and other countries. Last April, the company fired Matthew Cusick because he was HIV positive. This was after he spent four months learning his part in an act. A spokesman for the circus said Cusick was fired for safety reasons. They said he was a danger to others. He disagreed. Hundreds of people picketed a show in San Francisco. They said that firing him was not legal. Cusick says the company knew he was HIV positive when they hired him. It was not fair to let him put so much time into learning his act, and then fire him before he performed. He says he is not a danger to others. People can only get AIDS if infected blood contacts another person's blood, or open wound. The company says what their acrobats do is very, very dangerous. They perform tricks without nets. Someone might fall and get hurt, It could be bloody. They say it is too risky to let a person with HIV take part in an act. People who run the circus say it hurts to be accused of discrimination. Matthew Cusick says he feels hurt that he can't perform in the big blue and yellow tent. Dozens of artists, actors, writers and entertainers got involved in protesting the firing of Matthew Cusick. Some names you might know are: the Actors' Equity Union (45,000 members), Rosie O'Donnell, Rod McKuen, and Chad Allen. They also protested at a showing in Orange County. They said 'HIV discrimination is unacceptable.'

单选题 The first automobile was invented more than two hundred years ago. It used steam for power and had wooden wheels. The first automobile may have been simple and primitive, but it was an extremely important invention. The automobile today is the primary means of land transportation. It has produced more changes in our daily life than any other machines. Almost all gasoline engines work in the same way—with four movements, or strokes, of a piston in a cylinder. The first stroke pulls the fuel mixture (gasoline and air) into the cylinder. The second stroke compresses the fuel mixture. A spark plug produces a spark that ignites the fuel mixture and causes the third stroke. The final stroke removes any waste gases which might remain in the cylinder. The preceding paragraph explains what happens inside the cylinder to make the piston move. When the piston is pushed down by the explosion in the third stroke, it pushes the connecting rod. This rod rotates the crankshaft. The crankshaft is connected to other parts which turn the wheels. Most cars today have four, six, or eight cylinders.

单选题 Almost every family buys at least one copy of a newspaper every day. Some people subscribe to as many as two or three different newspapers. But why do people read newspapers? Five hundred years ago, news of important happenings—battles lost and won, kings or rulers overthrown or killed—took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in faraway countries on the same day they happen. Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and, of course, advertisements. There are all sorts of advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for their advertising space, but it is worth the money, for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.
