1970 was “World Conservation Year”. The United Nations wanted everyone to know that the world was in danger. They hoped that the governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.?

What will happen in the future? Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are hoping to save our world. They plant trees, build bridges across rivers in forests and so on. In a small town in the United States a large group of girls cleaned the banks of eleven kilometres of their river. Young people may hear about conservation through a record called “No, One's Going to Change our World. ” It was made by Scatles, Cliff Richard and other singers.

Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mom, I can’t peel potatoes. I have only one hand.”

Mom never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don’t ever use that as an excuse for anything again!”In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.

That night I told Mom about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, Mom looked carefully at the bars.

“Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every rung I reached. I’ll never forget the next time, crossing the rungs, I looked down at the kids who were standing with their mouths open.

One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mom come into my room. “Mom,” I said, weeping, “none of the boys would dance with me.”

For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.

An important question about eating out is who pays for the meal. If a friend of yours asks you to have lunch with him. You may say something like this, “I’m afraid it’ll have to be some place cheap, as I have very little money.” The other person may say, “OK, I’ll meet you at McDonald’s.” This means that two agree to go Dutch, that is, each person pays for himself. He may also say, “Oh, no. I want to take you to lunch at Johnson’s”, or “I want you to try the steak(牛排) there. It’s great.” This means the person wants to pay for both of you. If you feel friendly towards this person, you can go with him and you needn’t pay for the meal. You may just say, “Thank you. That would be very nice.”

American customs about who pays for dates(约会) are much the same as in other parts of the world. In the old days, American women wanted men to pay for all the meals. But, today, a university girl or a woman in the business world will usually pay her own way during the day. If a man asks her to dinner or a dance outside the working hours, it means “come as my guest”. So as you can see, it is a polite thing to make the question clear at the very beginning.
