The past fifty years or so have seen the gradual disappearing of animals from this earth, fishes from the sea, trees and plants from the land.

    Many factors result in this on pleasant phenomenon(现象). Among them, hunting is the main factor that endangers wild life. Some people kill wild life for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales.

    Apart from this, the rapidly growing human population threatens wild life on land, too. Towns expand and roads have to be built, so forests are burnt and trees are cut down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wild life. Tigers lions and leopards slowly die off without the food arm shelter that the forests provide.

    In addition, rapid urbanization (城市化) means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened.

    Man depends greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot, to without wild life; or he himself would die out. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wild life to continue living rather than to remove all signs of it.

    Man must learn to farm the sea as he does the land. He should control the amount and the frequency of his catch. Man also needs to build reserves, and to pass laws to stop the killing of animals, especially those that are already rare. To keep the present animal kingdom, the least that man can do is to clean the seas and to prevent pollution.

    I promised Michael I wouldn’t mention this until the season was over．Now l think it's time．

    Early last season, I wrote a column about an art of kindness I had seen Jordan do to a disabled child outside the stadium．After it ran，I got a call from a marl in the western suburbs．He said，“I read what you wrote about Jordan．but I thought I should tell you another thing I saw．”

Here it comes, I thought. It always does. Write something nice about a person, and people call you up to say that the person is not so nice.

    A few weeks later Jordan and I were talking about something else before a game, and I brought up what the man had said. Was the man right? Had Jordan really been talking to those two boys in that poor and dirty .neighborhood?

    "Not two boys," Jordan said. "But four."

    And he named them. He said four names. And what did they talk about?

    "Everything,” Jordan said. "Anything. I’ve asked to see their grades so that I can check to see if they're paying attention to their study. If it turns out that one or two of them may need teaching, I make sure they get it."

    It's just one more part of Michael Jordan's life one more thing that no one knows about, and one more thing Jordan does fight for. The NBA season is over now, and those boys have their memories. So do J! When the expert reviewers begin to tuna against Jordan as they surely will, I'll think about those boys under the streetlight, waiting for the man they know to come. For someone they can depend on.

   One night in February 1962, John H. Glenn, Jr. flew over Australia. The man in the Mercury  (水星) capsule was alone, but friendly voices reached him by radio. Over the dark land 100 miles below, he saw sparkling lights. It marked the city of Perth, where people had turned on their lights as a greeting to him.

   In Friendship 7, Glenn radioed, "The lights show up very well. Thank everybody for turning them on." His capsule moved on to the east.

   "During his three orbits of the earth, Glenn could always reach one of the 18 tracking stations. Some of them were on ships at sea. Others were in the United States.

   Many of the stations had been built with the help of other countries. These countries allowed  Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria,  Zanzibar and Mexico, there would have been breaks in the worldwide radio network. John Glenn, Jr. was the first American to orbit the earth. For his flight, the tracking network covered 60,000  statute miles (法定英里). 500 men worked in the stations along the route. Since his flight, the  network has grown. Today, it covers more than 100,000 statute miles and has about 100 stations. One-third of these stations are outside the United States.
