It was a cold day, but the students from Prosser Middle School in Chicago were sorting through the waste when they found that their school produces 1,500 pounds every day.
Prosser is just one school that throws out nearly 4,000 meal trays every day. Counting all of Chicago’s public schools, the number comes to nearly a quarter of a million a day. That’s more than 1 million a week and about 5 million a month.
“None of the trays are being recycled,” said a teacher. “ Everyone agrees that it’s very bad.”
Luckily, concerns about the environment and health have made some US cities take action. Dozens of schools have begun programs to reduce the use of food trays in school.
These schools have also banned (禁止)some fast food, including McDonald’s. Instead, they offer students recyclable trays. They encourage students to sort out lunchroom waste, then wash and recycle milk cartons and trays . So far, the program has helped schools to save a total of 820,000 trays each week.
Jay Stream Middle School in Illinois teaches its students how to collect trays. The school has cut its lunchroom waste by two thirds now that students recycle their used trays instead of breaking them.
Prosser Middle School also sees the benefits of the program. Students have organized about 20 clubs and volunteer activities to cut down on cafeteria garbage. They now recycle 80 percent of the school waste. “ I joined the club,” said Erika Santana, a 16-year-old junior in Prosser, “because I want to make Earth a better place.”

About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected（感染）in this matter. Perhaps, after all ,it is safer to be driven by a woman.
There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades (影子) of  green. Sometimes a person can’t tell the difference between blue and green. Only a few unlucky men may see everything in shades of green— a strange world indeed.
Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called “cones（锥状细胞）” . These help us to see in the bright light and to tell differences between colors. These are also millions of “rods“（杆状细胞），but these are used for seeing when it is nearly dark. They show us shapes but not colors.
Some insects have favorite colors. Mosquitoes(蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night.
【小题1】“Color blindness” means           in Chinese.
A. 盲目        B. 无色      C 色盲    D 讨厌颜色

be easy. The professor had said that they could bring any book or note they wanted. The only requirement(要求) was that they couldn’t talk with each other.
The professor handed out the papers. They were glad to find there were only five questions. Three hours passed. The professor asked, "How many of you have finished all the five questions?" None of the students answered.
"How many of 3’ou have finished four?" No answers again.
"Thee? Two?" The students moved restlessly (不安地) in their seats.
"One, then? Certainly somebody has finished  one." But the class remained silent.
"That is exactly what I expected," the professor said. "I just want to teach you a lesson--although you have completed four years of study, there are still many
things you don’t know about." Then be added, "You will all pass the exam, But remember: even though you are graduating from college, your education has just begun."
