Passage One
The Gulf Stream, which runs like a friendly blue river across the cold green Atlantic Ocean, is one of the mightiest powers in the worlD. By comparison, the Mississippi and the mighty Amazon are but small rivers. Two million tons of coal burned every minute would not equal the heat that the Stream gives forth in its Atlantic crossing. Without the Stream’s warmth England’s pleasant green countryside would be as cold as Labrador, which is no farther north than EnglanD. If this "river of blue" were cooled as much as 15 degrees, England, Scandinavia, northern France and Germany would probably become a region for the Eskimos.
The general course of the blue river has never been known to change. From Florida north the Stream follows the curve of the coast but stays well away from the shore. When the warm waters meet the icy Labrador currents, the Stream loses some speed and heat, but even with icebergs at its margin it stays warm

Annie is a longtime secretary/receptionist for two senior vice presidents
at a big company. They have been doing a lot of hiring lately, and almost all of
the new middle-management personnel have been interviewed by one or the other of
Annie’s two bosses, so naturally they come through her office first.
Some of these people are unbelievably rude. Either they treat Annie like a
piece of furniture (no hello, no eye contact) or they think she is their errand

impressions of job candidates. So far this week, two have been discourteous

There Pictures from outer space now show us how much land has changed on earth. These images are taken by Landsat 7, a government satellite. The satellites have been used for 27 years. They reveal the clear-cutting of forests in the northwestern part of the United States. Pictures show the loss of rain forests in South America.
NASA’s Darrel Williams speaks about the Landsat 7 Project. He said that an eruption caused trees to burn up in a large forest. Fifteen years later, pinkish images from space show that the trees and plant life are growing again. Williams says that clear-cut areas easily show up in the pictures. He wants Americans to look at how much land is being cleared of forests in our country.
Satellites have provided other information about changes on earth. In the past ten years, more than four miles have shrunk from glaciers in Alaska. Landsat 7 received these computer images of Glacier Bay in Alaska.
