Think about what you like to wear on the weekend.There's a good chance that you like to put on a pair of blue jeans.At any moment，about half of the world's population is wearing jeans.But according to a new study，our love for jeans may be bad for Earth.Denim （牛仔布）might be putting some sea animals in danger.
Every time we wash our jeans，tiny bits of denim will flow out of our washing machines，down into the world's rivers，lakes and oceans.
You might wonder：Isn't denim made of cotton，a natural material？How can it become a danger to nature？Well，in the process of making jeans，denim is treated with many types of man﹣made chemicals.Some improve its durability （耐用性）and feel；others give jeans their blue color.
Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada.They found denim waste in all of the samples （样本）they had collected.It is feared that the harmful chemicals in denim have spread far and wide.Scientists aren't yet sure how these chemicals might harm animals.
In the study，the scientists also washed jeans to see how many bits of denim each pair would drop per wash.The answer was frightening：About 50，000.Not all of them make their way into the environment.Wastewater treatment plants hold back 83 to 99 percent of them.This may sound pretty good.However，one percent of 50，000 bits are still 500 per wash.Now think about the number of jeans around the world and the times each of them gets washed.As a result，a large amount of denim waste still gets into the environment.
Does this mean we shouldn't wear jeans？Probably not" We need to buy fewer jeans and only wash them when we truly need to do it，" says Sam Athey，one of the scientists. " You don't need to wash your jeans after having worn them only a couple of times. "

（3）How many bits of denim might get into the environment every year？
| A． |
Five hundred. |
| B． |

Galileo Galilei was born in Pisa, Italy, in 1564. His father taught music while his mother cared for kids at home. The family was not wealthy, but Galileo's parents paid for him to go to school.
At first Galileo planned to become a doctor, but he changed his mind. He liked a different kind of science-physics. In Galileo's time, not much was known about how objects moved. Centuries earlier, a Greek（希腊人）named Aristotle had written down his ideas about movements, and everyone seemed to believe them. Galileo questioned those ideas and did experiments （实验）that showed how things really worked. For example, Aristotle thought that a heavier object would fall faster than a lighter one of the same size and shape. No one had ever really tested this idea. It just seemed to be true. Then Galileo came along, dropped two balls from a high tower, and discovered that they hit the ground at the same time!
In later years, Galileo became interested in how the stars and planets move. He watched the sky with a telescope（望远镜）he built himself. Once again, he saw things no one had ever seen before. For example, he saw that the moon was not smooth. Then he noticed that the sun had spots （斑点）that seemed to move. Galileo realized from his observations （观察）that the earth was moving around the sun. A Polish （波兰的）scientist named Copernicus had said this recently, but no one believed him. Galileo knew that Copernicus was right. Unluckily, Galileo's announcement got him into trouble with the Catholic Church. The Catholic Church said that the earth was at the center of the universe （宇宙）with the sun traveling around it. This was what people had long believed, but Galileo said it was untrue. So he was sent to prison（监狱）. He was soon set free, but for the rest of his life he had to stay in his house and yard.
Galileo died in 1642, but his work helped to change the world. He is sometimes called the father of modern science,because he showed us how important it is to look carefully at things and to test out ideas with experiments.
