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.

    Would you buy a car that released calming smells into the air when you are stuck in heavy traffic? Would you buy a robot that smells like a human being?

    Many people have seen the 3-D computer-made environments of virtual reality (VR). Now these virtual worlds will not just look and sound real. Researchers have created VR environments that even smell like the real things. With the new technology, users open a virtual door and step into a new environment, like a rainforest. After they enter this virtual world, special equipment releases forest-like smells into the air to make the experience seem more real.

    Suzanne Fisher-Murray said, “it is a really wonderful experience that you have because you're exploring this environment and you have smells with it.”

    In the United States, Smell-O-Vision was designed to provide smells during the showing of a movie. The Smell-0-Vision system was once popular in the 1960s. Now, Emanuela Maggioni says it is close to becoming popular again. “The connection with emotions, memories, and…the sense of smell,” Maggioni said. “It is unbelievable what we can do with technology.”

    The uses for smell technology are not just limited to films and the performing arts. Researchers showed a computer program where users could imagine themselves driving a car. The system included a special smell-spraying machine. Dmitrijs Dmitrenko said, “We want to deliver the smell of lavender（薰衣草）every time the person drives over the speed limit. We choose lavender because it's a very calming smell.”

    Scientists are experimenting with smell instead of sounds or image-based alerts on telecommunications equipment. And businesses are already using smell to influence people's behavior. “Not only.…in stores…But on the other side, you can create and stimulate immediate buying,” Maggioni said. “So you're in a library and you smell coffee and actually you are unconsciously having the need to drink a coffee.”

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

    Bike Batman is a 30 - year – old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

    About three year, ago, he was looking for his wife. He found one on Craigslist, a website where people list things they want so sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on? Bike Index. Then he called the person who claimed to be the bike's owner and arranged to meet him－supposedly to complete the sale. When the two men met, Bike Batman told the thief. You've got two option. You can wait until a police officer gets here, or you can just get out of here." You can imagine what the thief did.

    After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet - up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes y the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

    His nickname came from a discussion with a police officer who suggested he be called "Robin Hood". Since he wasn't exactly stealing from the rich and giving to the poor, "Batman" seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.

More than half of the 1,000 consumers surveyed by Credit Karma said they have impulsively(冲动地) shopped to deal with feelings of stress, anxiety or depression. Twenty-three percent of respondents said they've maxed out (刷爆) a credit card in the past year.

As for age, 68 percent youngsters, responded by saying they have experienced it in the past, compared to 53 percent of the middle-aged and only 26 percent of the old

In regards to genders, 48 percent of men and 31 percent of women who have stress spent said they had purchased alcohol when stressed. Eighty-two percent of women stress spent on clothing compared to 52 percent of men. Women also lead stress spending for jewellery, 42 percent, compared to 22 percent for men with men stress spending more for electronics 44 percent while 30 percent for women.

In fact, shopping to reduce stress can actually help you live a healthier life by making sure that your blood pressure is lowered. Shopping to relieve stress is also called shopping therapy (疗法) as a form of reducing stress.

The survey found that that 82 percent had only positive feelings about their purchases and that the positive mood boost that followed those purchases was long-lasting.

However, the side effect of shopping therapy, for many, can start out as a relatively harmless mood booster but could possibly grow into a financial loss, cause conflict, and therefore add a large amount of stress to a person's life.

I just returned from India. While driving home from the airport, I was amazed by how everything in American streets 1 those in Delhi, a city in northern India. "You can eat off the street here!" I said. My family looked at me 2 I had gotten off a spaceship rather than a plane.

During the two years I was away, my friends and family 3 sending texts to each other by phone. After I came back, my phone was no longer 4 as before, just lighting up with the "ding" sound of a text, and I felt very 5 . I chose to talk to my friends instead of texting them. I asked my friends for their 6 as I made an effort to7 with them and rebuild our friendships.

While I was on my 8 trips, most of my friends had moved on with their 9 . We felt disconnected from each other's experiences. Just as 10 would always be part of my life, I understood that raising a family would always be part of theirs. I told them sometimes I felt 11 because I had been away and wasn't there for their 12 events.

Expats（侨民）in Laos say that sometimes, if you stay abroad too long, you become a permanent 13 . never quite making it as a local, and never feeling 14 in your home country. I 15 . If you always travel with a heart beating for your beloved ones, no matter how long you have been abroad, you will find satisfaction at home.

I suffered my brain injury from a car accident. I was rear-ended(追尾) twice 1 , which caused my head to hit the headrest each time I was hit. I had received news over time from my doctor, which was mentally and emotionally 2 for any 18-year-old to accept. I was 3 , and did not know what this meant for me and my future. Throughout the journey, I tried to 4 why I didn't feel like myself two years after the accident and recognized things I never had 5 with before, such as being unable to remember pretty much anything. My 6 had increased and I did go through days of depression. I wanted to be a 7 but I felt as though that dream would never be reached.

       Sitting in bed feeling 8 , I tried to focus on why I wanted to be a lawyer. I 9 myself that I was the only one holding myself back from making that 10 a reality. Thinking of this, I pulled myself together and have been fighting for my dream ever since. And I am 11 with my bachelor's degree in criminal justice and two pre-law certificates in 3 years at Florida International University.

12 I have to work ten times harder than I would have if I hadn't had this 13 , I wouldn't take it back. I am 14 now due to the things that have happened to me. Nothing is impossible, but it is how you take on a(an) 15 that will get you to where you want to be.
