What and When Is Earth Day?

When I proposed to name Earth Day, a global occasion to celebrate the wonder of life on our planet, I thought long and hard about what day to choose. It must be meaningful and must be accepted by people . When I came across the Vernal Equinox (春分), I immediately knew it was right . What could be better than the first day of spring when hearts and minds can join together with thoughts of peace and the awakening of the earth. So the first Earth Day was celebrated in San Francisco, on March 21, 1970. The United Nations later accepted the day as a yearly event for people all over the world. Each year the United Nations Peace Bell rings at the moment spring begins.

D. Translate the following passage from Text A into Chinese.

The earth means many things to the people who live on it. To a farmer, the earth is rich soil. To a road builder, the earth means mountains of hard rock. For a sailor, the earth is water as far as the eye can see. A pilot’s view of the earth may include part of an ocean, a mountain, and patches of farmland. An astronaut speeding through space sees the earth’s round shape and the outline of lands and oceans. Each of these different views helps describe the earth but none really tells what the earth is.

地球对于地球上的居民来说，意味着许多事物。对于农民来说，地球是肥沃的土壤；对于修路工人来说，地球是由坚硬石块构成的山峰；对于水手来说，地球是一望无际的水域；在飞行员眼中，地球可能会包括部分海洋、山峰和成片农田；在太空高速行进的宇航员看到的地球是圆形的球体，还有海洋和陆地的轮廓。他们关于地球的不同看法都有助于对地球进行描述，但都没有真正揭示地球究竟是什么。
