On Sunday, April 22, 1990, people all over the world celebrated the same holiday. It was the twentieth anniversary of Earth Day. The purpose of the holiday, which we celebrate every year on that date, is to help people learn how to protect the planet Earth. People around the world celebrate Earth Day because they worry about the planet. Many forms of animal life are disappearing from the earth. Carelessness and accidents in many countries have caused problems that are harmful to the environment. Air and water pollution, oil spills, and toxic waste are some of the serious problems.
In fact, protecting the earth is truly a worldwide issue. Pollution in one place often affects areas far away. For example, an accident in a nuclear power plant in one country can create a radioactive cloud that goes halfway around the world. Factory smoke in one country can cause acid rain in another. It is easy to see how our protecting the environment has become an international issue.
So, in order to begin the difficult job of saving the earth, people around the world did special things on Earth Day, 1990. In Japan, divers pulled garbage from the sea. In Nepal, hikers picked up trash on Mount Everest. Students marched in support of Earth Day in Hong Kong, and people planted medicinal herbs in the Philippines. In the United States, children planted trees. Native Americans told legends about the creation of the earth, artists drew pictures on walls next to highways, and musicians gave concerts to Support the work of environmental groups. Almost everyone everywhere stopped for a moment to think about how we can protect the earth.

A:April 22 B:April 22, 1970 C:April 22, 1990 D:Sunday, April 22

A:It occurs every fourth year B:It starts on March 15. C:It is known as "March Madness". D:It lasts through the beginning of April

第一篇 　　 March Madness 　　For the rest of the month, an epidemic (传染病) will sweep across the US. It will keep kids home from school. College students will ignore piles of homework. Employees will suddenly lose their abilities to concentrate. 　　The disease, known as "March Madness", refers to the yearly 65-team US men’s college basketball tournament. It begins on March 15 and lasts through the beginning of April. Teams compete against each other in a single elimination tournament that eventually crowns a national champion. 　　Nearly 20 million Americans will find themselves prisoners of basketball festival madness. 　　The fun comes partly from guessing the winners for every game. Friends compete against friends, husbands against wives, and colleagues against bosses. 　　Big-name schools are usually favored to advance into the tournament. But each year there are dark horses from little-known universities. 　　This adds to the madness. Watching a team from a school with 3,000 students beat a team from a school with 30,000, for many Americans, is an exciting experience. Last year, the little-known George Mason University was one of the final four teams. Many people had never even heard of the university before the tournament. 　　College basketball players are not paid, so the game is more about making a name for their university and themselves. But that doesn’t mean money isn’t involved. 　　About $4 billion will be spent gambling on the event. According to Media Life 　　magazine, the event will draw over $500 million in advertising revenue this year, topping the post-season revenue, including that of the NBA (全国篮球协会). Which statement about the epidemic is NOT true?

A:It starts on March 15. B:It does not occur annually. C:It is known as "March Madness" D:It lasts through the beginning of April.
