Do you suppose Darwin, one of the greatest scientists of all times, really
did fools' experiments?
Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes people think they already know the answer to a question or the solution (解决办法) to a problem. Sometimes they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for (满足于) just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop two sheets of paper which are exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheet. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything.
But this simple experiment is important. It explains part of our present-day understanding of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Science sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, what we might think is foolish, can shake the foundations (基础) of science.

Most people think of racing when they see greyhounds（灰狗）and believe they need lots of exercise. They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive（好斗的）because they are big in size. In fact greyhounds love people and are gentle with children.
Greyhounds can live for 12 – 14 years but usually only race for two or three years, and after that they make great pets. They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size.
Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33 cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these.
Greyhounds have smooth body coats, low body fat and are very healthy. Because they’re slim（苗条的）they don’t have the leg problems like other dogs the same height . But they do feel the cold, especially since they would much rather be at home in bed than walking around outside.The text is written mainly.

There was a story many years ago of a school teacher--- Mrs. Thompson. She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He didn’t play well with the other children and he always needed a bath. She did not like him.
Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed of herself. She felt even worse when, like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume(香水).
Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left she cried for at least an hour. On that very day, she stopped teaching reading, writing and math. Instead, she began to teach children.
Mrs. Thompson paid particular attention to Teddy. The boy’s mind seemed to come alive. The more she encouraged him, the faster he improved. By the end of the sixth grade, Teddy had become one of the smartest children in the class.
Six years went by before she got a note from Teddy. He wrote that he had finished high school, third in his class, and she was still the best teacher he ever had in his whole lift. He went to college. Mrs. Thompson got two more letters from him with the last one signed, Theodore F. Stoddard, M. D.(医学博士).
The story doesn’t end there. On his wedding day, Dr. Stoddard whispered in Mrs. Thompson’s ear, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I could make a difference.”
