Jack's sister gave him a car as a Christmas present. On Christmas Eve when Jack came out of his office, a street boy was walking around the shiny new car, admiring it. ''Is this your car, Mister? ''he asked. Jack nodded. ''My sister gave it to me for Christmas. '' The boy was astonished. ''You mean your sister gave it to you and it didn't cost you anything? Boy, I wish…'' He hesitated. Of course Jack knew what he was going to wish for. He was going to wish he had a sister like that. But what the kid said made Jack quite surprised.
''I wish,'' the boy went on, ''that I could be a sister like that.'' Jack looked at the boy in astonishment, and then impulsively he added, ''Would you like to take a ride in my automobile?''
''Oh, yes, I'd love that.'' After a short ride, the boy turned and with his eyes shining, said, ''Mister, would you mind driving in front of my house?'' Jack smiled a little. He thought he knew what he wanted. He wanted to show his neighbors that he could ride home in a big automobile. But Jack was wrong again.
''Will you stop where those two steps are?'' the boy asked. He ran up the steps. Then after a little while Jack saw him coming back, but he was not coming fast. He was carrying his little crippled sister. He sat her down on the bottom step and pointed to the car. ''There she is, Buddy, just like I told you upstairs. His sister gave it to him for Christmas and it didn't cost him a cent. And some day I’m going to give you one just like it. . . then you can see for yourself all the pretty things in the Christmas windows that I've been trying to tell you about.”
Jack got out and lifted the kid to the front seat of his car. The shining-eyed older sister climbed in beside him and the three of them began a memorable holiday ride.
That Christmas Eve, Jack learned that it was more blessed to give…

The brain, rather than our eyes, may be more important for sight, researchers studying fruit flies have discovered. The discovery could change the way we think about vision.
Researchers in the University of Virginia have found that the very simple eyes of fruit fly larva (幼虫), with only 24 total photoreceptors (感光细胞) (the human eye contains more than 125 million), provide just enough light input to allow the animal’s large brain to make that input into images. Their discovery shows that vision may be less important to “seeing” than previously thought—and in fact it is the brain’s ability to process points of light into complex images that is key.
“It blows open how we think about vision.” said Barry Condron. “This tells us that visual input may not be as important to sight as the brain working behind it.”
Condron’s graduate students, Elizabeth Daubert, Nick Macedonia and Catherine Hamilton, conducted a series of experiments to test the vision of fruit fly larvae. They found that when a larva was tied to the bottom of a dish, other larvae were attracted to it as it attempted to free itself. After several further experiments to understand how they sensed the motion, the researchers learned that the nearly blind animals likely were seeing the action.
“The answer must be in the brain of these animals.” Condron said. “They are able to take just a couple dozen points of light and then process that into recognizable images; something like when an astronomer with a small telescope is able to use techniques to improve a limited image into useful information about a star.” Condron believes the animals are able to assemble useful images by rapidly scanning their heads and, in doing so, gather up enough light points to allow the brain to compose an image clear enough to “see”.
The researchers tested this by presenting larva with a video (therefore no sound and no smell) and found that the larvae still sensed and sought out the struggling larva on the video. This provides us with a good model for trying to understand the role that the brain plays in helping organisms, including humans, to process images, such as recognizing faces.

Five years ago, famous writer Mike became very ill. His body ached and he felt constantly tired. It was difficult for him to even move around. His doctor told him that he would lose the ability to move and _______ die from the disease. He was told he had only a 1 in 500 chance of survival.
Despite the diagnosis (诊断), Mike was _______ to overcome the disease and survive. He had always been interested in medicine and had read a book, which discussed the idea of how body chemistry and health can be damaged by emotional stress and negative _______. The book made Mike think about the possible _______ of positive attitudes and emotions. He thought, “Is it possible that love, hope, faith, laughter, confidence, and the _______ to live have positive treatment value?”
He decided to concentrate on positive emotions as a way to treat some of the symptoms of his disease. In addition to his traditional medical treatment, he tried to put himself in situations that would _______ positive emotions. “Laugh therapy” became part of his treatment. He _______ time each day for watching comedy films, reading humorous books, and doing other activities that would draw out _______ emotions.
