When my sister Gina was born, she had a problem with her heart. Her heart was pretty bad in the beginning and she stayed in the hospital for a month. The first few years were very difficult because she was very sick. She had five operations before she was three years old. She had trouble walking, playing with other children, and going to school.

    Although Gina couldn't laugh and talk, we all knew that she just needed love and care. Our parents wanted to take Gina to a special place in Florida where she could swim with dolphins. Gina was afraid of swimming with them because she had never been around dolphins before. We had also never traveled that far as a family.

    When we got to Florida, we saw where the dolphins lived. It was a place where kids with special needs like Gina could come and spend time. I thought it was going to be a vacation, but it wasn't. Gina had to work hard every day for a week.

    The trip was amazing .Gina laughed and clapped(拍手) when she saw the dolphin, and the dolphin splashed (溅起水花) when it saw Gina. They swam together all day. Gina was able to move her body more than she normally did at home. Mom and dad were proud of Gina. I was, too.

Make Up Your Mind to Succeed

    Kind-hearted parents have unknowingly left their children defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and performance were played down because “everyone's a winner.” And their report cards sounded more positive  than ever before. As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation.”

    Dweck has been studying how people deal with failure for 40 years. Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it. Here's how they work:

    A fixed mind-set is grounded in the belief that talent is genetic – you're a born artist, point guard, or numbers person. The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame. When things get difficult, it's quick to blame, lie, and even stay away from future difficulties.

    On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego (自尊) isn't on the line as much, the growth mind-set sees failure as a chance rather than shame. When faced with a difficulty, it's quick to rethink, change and try again. In fact, it enjoys this experience.

    We are all born with growth mind-sets. (Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise. Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.

    I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard to keep my house from becoming a battlefield.

    It got worse as they grew older. Three years ago, Zack, then 16, couldn't make it through a day without making his sisters, Alex 11 and Taryn 9, angry.

    My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was "I say it because it's true."

    I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister, Mary, in an email. She replied, "Don't email me. Email him."

    Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn't say anything different, but email just took the tension away. There'd be no shouting or door banging. Zack wouldn't feel under attack.

    Zack didn't reply for days. When he finally did, his entire message was four small words. I smiled when I read them: "You're right. I'm sorry."

    The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don't tune me out as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, "You're so much nicer online."

    All I know is that the house is quiet. But we're talking.

Earthworms don't move fast. But humans can accelerate the worms' spread. Fishermen often use invasive(蔓延性的) earthworms to catch fish. Many have introduced invasive earthworms to rivers, streams and lakes previously unexposed to these animals. Gardeners who use earthworms to make their soil rich may unknowingly introduce invasive ones. The worms even give rides in the mud on wheels, potted plants and road materials shipped around the nation.

But they're not everywhere yet. In the Great Lakes region, "20 percent of the land is earthworm-free," says Cindy Hale, a research biologist. Of the remaining 80 percent of land, half of the land has fewer than two earthworm species-meaning there isn't yet too much impact on the ecosystem, she explains. For these regions, she says, now is the time to take action. According to Hale, educating the public, especially fishermen, is one approach to stopping the spread of invasive earthworms. Identifying which lands are currently earthworm-free is another.

Ryan Huefimeier, a program coordinator for Great Lakes Wom Watch, has been working on a model that will help create large maps of areas with minimal(最小的) or no damage from earthworms. Ultimately, landowners can use it to identify earthworm activity on their property. once identified, lands with minimal or no earthworm damage should be protected.

But scientists suspect that once invasive earthworms arrive they can't be removed. And even if all could be, affected forests might never return to the way they were. "It's very much a story of learning to live with them," concludes Lee Frelich of the University of Minnesota's Center for Forest Ecology.

Forest ecologists have called earthworms "ecosystem engineers" because they can change or create habitats that otherwise would not be present. Whether this is a good thing depends on the situation.

"What the earthworms do and how we value it is what really matters." said Hale. "In one place-farm fields or gardens-we really like European earthworms and what they do, so we consider them good. In native hardwood forests, we really don't like what they do-so we consider them bad. You really have to understand how an organism(微生物) affects an ecosystem. Things aren't black and white."
