Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood. When I was a boy of 12, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. It's the most beautiful sound in the world.

     I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day, my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my pet bird was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries(浆果). She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

I'm seventeen. I had worked as a box boy at a supermarket in Los Angeles. People came to the counter and you put things in their bags for them and carried things to their cars. It was hard work.

While working, you wear a plate with your name on it. I once met someone I knew years ago. I remembered his name and said, "Mr. Castle, how are you?" We talked about this and that. As he left, he said, "It was nice talking to you, Brett." I felt great, he remembered me. Then I looked down at my name plate. Oh, no. He didn't remember me at all. He just read the name plate. I wish I had put "Irving" down on my name plate. If he'd have said, "Oh yes, Irving, how could I forget you?" I'd have been ready for him. There's nothing personal here.

The manager and everyone else who were a step above the box boys often shouted orders. One of these was: you couldn't accept tips. Okay, I'm outside and I put the bags in the car. For a lot of people, the natural reaction is to take a quarter and give it to me. I'd say, "I'm sorry, I can't." They'd get angry. When you give someone a tip, you're sort of being polite. You take a quarter and you put it in their hand and you expect them to say, "Oh, thanks a lot." When you say, "I'm sorry, I can't." they feel a little put down. They say, "No one will know." And they put it in your pocket. You say, "I really can't."

It gets to a point where you almost have to hurt a person physically to prevent him from tipping you. It was not in agreement with the store's belief in being friendly. Accepting tips was a friendly thing and made the customer feel good. I just couldn't understand the strangeness of some people's ideas. One lady actually put it in my pocket, got in the car, and drove away. I would have had to throw the quarter at her or eaten it or something.

    I had decided that one year was enough. Some people needed the job to stay alive and fed. I guess I had the means and could afford to hate it and give it up.

    A heartbroken dog whose owner died two months ago is missing her so much that he attends services every day at the Italian church where her funeral was held, patiently waiting for her to return.

    Tommy, a seven-year-old dog, belonged to Maria Lochi, 57, and had been her faithful partner after she adopted him when she found him in fields close to her home. Mrs. Lochi adopted several dogs she found but friends said she developed a close friendship with Tommy and would walk to church with him every day, where he would be allowed to sit patiently by her feet.

    Father Panna said, “He's there every time I celebrate Mass and is very well behaved. He doesn't make a sound, and I've not heard one bark from him in all the time he has been in. He used to come with Maria and he was obviously devoted to her. I let him stay inside as he was always so well behaved and none of the other people ever complained to me. He's still coming to Mass even after Maria's funeral, he just sat there quietly. I didn't have the heart to throw him out. I've just recently lost my own dog so I leave him there until Mass finishes and then I let him out.”

    Tommy's been adopted by everyone in the village now and he is everybody's friend. Everyone looks out for him and leaves food for him, although it would be nice to find a proper home for him.

    The story of Tommy is similar to the 2009 Hollywood film Hachi which told of how a faithful Akita dog waits patiently for his master after he also dies. It was based on the true story of a Japanese Akita called Hachi, whose owner died in 1925 but for the next nine years he waited patiently at the railway station for his owner from where they regularly caught a train.

    READY or not, the college application season has begun. There are two main kinds of early admissions programs: Early Action and Early Decision.

    Early Action is a great choice for the well-prepared student. Students apply early, and are allowed to apply under an Early Action program to as many colleges as they choose. The biggest advantage for students is that colleges let them know early – in most cases, before Jan 1. Roughly 15 percent of colleges and universities offer an Early Action option(选择). Oct 15 is now the first deadline for many colleges and universities. This movement toward earlier deadlines is especially popular in the Southeast, with many of the large public universities leading the way. North Carolina State University, the University of South Carolina and the University of Georgia all have an Oct 15 Early Action deadline.

    Early Decision is a promise that cannot be reversed. Students who are accepted must take back their other applications and should attend that school. Students are allowed to apply to just one school under an Early Decision program. Early Decision deadlines are in early November, with colleges letting students know by mid-December. Many students believe that they are more likely to be accepted if they apply for Early Decision, but it actually depends.

       In some cases there is big increase in students being accepted, and at other colleges it is not that big at all. Generally, the strongest students are applying early. Athletes and students with focused interests are encouraged to apply for Early Decision.

    A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

    Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

    In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

    The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo's Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

    One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

    Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

    The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

    Parallel worlds exist and interact with our world, say physicists.

    Quantum mechanics (量子力学), though firmly tested, is so weird and anti-intuitive that physicist Richard Feynman once remarked, “I think I can safely say nobody understands quantum mechanics.” Attempts to explain some of the bizarre (奇异的) consequences of quantum theory have led to some mind-bending ideas, such as the Copenhagen interpretation and the many-worlds interpretation.

    Now there's a new theory on the block, called the “many interacting worlds” hypothesis (假设) (MIW), and the idea is just as profound as it sounds. The theory suggests not only parallel worlds exist, but that they interact with our world on the quantum level and are thus detectable. Though still speculative (推测的), the theory may help to finally explain some of the bizarre consequences inherent in quantum mechanics.

    The theory is a spinoff of the many-worlds interpretation in quantum mechanics—an assumption that all possible alternative histories and futures are real, each representing an actual, though parallel, world. One problem with the many-worlds interpretation, however, has been that it is fundamentally untestable, since observations can only be made in our world. Happenings in these proposed “parallel” worlds can thus only be imagined.

    MIW, however, says otherwise. It suggests that parallel worlds can interact on the quantum level, and in fact that they do.

    “The idea of parallel universes in quantum mechanics has been around since 1957,” explained Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the physicists to come up with MIW. “In the well-known 'Many-Worlds Interpretation', each universe branches into a bunch of new universes every time a quantum measurement is made. All possibilities are therefore realized — in some universes the dinosaur-killing asteroid (小行星) missed Earth. In others, Australia was colonized by the Portuguese.”

    “But critics question the reality of these other universes, since they do not influence our universe at all,” he added. “On this score, our 'Many Interacting Worlds' approach is completely different, as its name implies.”

    Wiseman and colleagues have proposed that there exists “a universal force of repulsion between 'nearby'(i.e. similar) worlds, which tends to make them more dissimilar.” Quantum effects can be explained by factoring in this force, they propose.

    When asked about whether their theory might imply that humans could someday interact with other worlds, Wiseman said: “It's not part of our theory. But the idea of human interactions with other universes is no longer pure fantasy.”

    What might your life look like if you made different choices? Maybe one day you'll be able to look into one of these alternative worlds and find out.
