听力原文：Judy: Hi, Tom!
Tom: Judy. I haven't seen you in weeks. Where have you been？
Judy: In Florida.
Tom: What vacationing! While the rest of us is studying on the campus in February cold？
Judy: Not exactly. I spent most of my time under water.
Tom: I don't understand.
Judy: I was on a special field trip. I went with my marine biology class.
Tom: So you went scuba diving. What were you looking for, sunken treasure？
Judy: You might say so. The sea's full of treasures. All kinds of strange fascinating organisms. Our class concentrated on studying plankton.
Tom: I thought planktons were too small to be seen.
Judy: That, s common misconception. The term plankton covers a wild variety of freely flowing plants and animals, from microscopic one cell organisms to larger ones, such as the common jellyfish.
Tom: Jellyfish maybe large enough to be seen. But they are transparent, aren't they？
Judy: Yes, most planktons have transparent tissues as protected camouflage, it makes them practical in visible to predators.
Tom: But not invisible to your biology class, I hope.
Judy: By concentrating, I was able to see the outlines of lots of different plankton plants and animals. In fact, our professor even took photographs of Greeber Quadata which are small oceanic snails.
Tom: How would the snails show up in the photographs if they are transparent？
Judy: We scoured it, Greeber Quadata, with harmless green dye. Since particles of the dyes stuck to their tissues, the snails appeared in green outline in the photographs.
Tom: That sounds like an interesting trip. But I think if I've been in Florida in February, I'd much rather spend my time just swimming and lying in the sun.
How did Judy spend most of her time in Florida？
Even though they were forced to serve in separated units, black soldiers distinguished themselves in combat. This was despite the fact the whites had long believed that blacks could neither command nor use firearms. In 1863, William Carney of the Massachusetts Colored Infantry received the Congressional Medal of Honor for his role in battles with the Plains Indians. Isaiah Dorman, Coster's black scout, served and died at the Little Big Horn in 1876. Henry Flipper was the first black graduate of West Point in 1877.
In World War I, 40,000 black American combat soldiers served with the French command. Neither U.S. nor British commanders would use these men. But Henry Johnson and Needham Roberts, soldiers in the 369th Infantry's black “Hellfighters” were still the first Americans to win the Croix de Guerr, France's top military award.
During World War II over 600,000 black men and women served in the armed forces, including some 400,000 who served overseas. Dorie Miller, a black mess attendant in navy, was one of our first heroes in this war. At Pearl Harbor during the Japanese sneak attack, he manned a machine gun and shot down four planes. The black fighter pilots of Benjamin Davis, Jr. distinguished themselves throughout the war. They served most courageously during the Italian campaign. During the war in Vietnam, mainly because of civil rights pressures in America but also owing to the fine record of black military units, all American forces were fully integrated. Once again blacks played vital roles. And 13. 2 percent of all war deaths were of blacks, even though blacks constitute only 11 percent of all Americans. Black American soldiers continue to serve their land well.
