Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.

On September 22, 1986, Jay Brunkella, a police officer in the Rogers Park district in Chicago, was shot during a drug arrest and died. Shortly afterwards, fellow officer Ken Knapcik, a 20-year veteran（老警官）of the force, returned home after work to find a note from his 15 year old daughter on the dining table.
Dad—This poem came directly from my heart. I love you so much! It scares and amazes me that you go out every day and risk everything to provide us with all that we have. I wrote this to express how much I love you and how much lost I’d be without you ---Laura. PS: Hey, let’s be careful out there.
Titled The Ultimate Cop, Laura’s poem was dedicated “To all the cops in the world who have daughters who love them with all their hearts. And especially to my dad”. It was about a police officer’s daughter who sees on the night time news that her father has been shot. Part of poem: “Daddy, my Daddy, can you hear me cry? Oh, God, I need my Daddy, please don’t let him die.”
Ken Knapcik stood alone as he read the poem. “It took me several minutes,” he said. “I’d get through part of it and have to stop before I could go on. I was weeping. She had never told me she was scared.” He took the poem to work the next day and showed it to his fellow officers. I’ve never seen so many grown men cry. Some couldn’t finish it.”
Knapcik keeps Laura’s poem in the pocket of his police jacket. He takes it with him every time he leaves the house for a new shift. “I don’t want to be out there without it,” he said. “I’ll probably carry it with me forever.”

How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words.
The power of words, then, lies in their association—the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey （表达，传递）his meaning in words which sing like music, and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and vulgar.（粗俗的）

A. The importance of choosing words.

WILD WEATHERMAN
Name: Sam Champion
Hot job: TV Weatherman
Where: ABC-TV, New York City
When you were a child, did you plan to forecast wind, rain, and snow on TV?
I wanted to be a foreign journalist. I took courses in weather science at Eastern Kentucky University, but I majored in broadcasting news.
How did you finally become a weatherman?
My first job in the early 1980s was at the local TV station in Paducah, Kentucky. I did everything from turning on the lights in the morning to writing and delivering morning news. I put together weather forecasts, and became interested in them.
Back then, how did you forecast weather?
Independent companies collected computer information that showed, for example, how a single weather system might split into snow or snow mixed with rain. The information was often opposite and the job of a weatherman was to study the information and make the best educated guess about the storm.
Has weather forecasting changed much with new technology?
Advanced computers, satellites, and Doppler radar (sound waves used to track storms) have made forecasting more exact. But we still know very little about how weather is shaped. So far, we just have theories.
Any advice for children who’d like to become weather scientists?
To me, weather is the most exciting field in the world. There are still so many more questions about weather than answers. After all, if we can’t foresee floods or hurricanes, how safe a society are we? Weather forecasting is wide open for scientists who love to solve puzzling problems. The next generation of meteorologists (weather scientists) will unlock many of Earth’s weather secrets. So get a general knowledge of Earth science, and study meteorology in college.
Thanks, Sam.
