I was at a loss for how to handle the fights among my kick- Many activities had been tried, but they didn't work. After reading What I Know for Sure written by Oprah Winfrey, a thought occurred to me one day.

    “Starting with Dora, I want everyone to find the chance to say 'thank you' .” I declared.

    “What?” Ashley asked. “What's going on?''

    “Just do it.”

    Naturally, the kid^ all thought I had lost my mind. I wasn't sure if they were wrong, but I pressed on.

    “Now, we're going to keep going around and everyone tells what they're thankful for.”

    Clearly doubtful and frustrated, the kids launched in, and I kept them going.

    “I'm thankful for our house.”

    “I'm thankful for my clothes.”

    “I'm thankful for my whole life and everyone in the world.”

    “What? What am I supposed to say?”

    "Keep going."

    “I'm grateful for my underwear!” Instant laughter erupted, music to my ears!

    “Great, lei it out!” I encouraged. “What else?”

And that was all we needed. The gratitude--great and small, serious and funny—came rolling out.

    “My backpack.”

    “My teachers.”

    On and on it went until every face was lit with a new kind of joy and laughter. I could sense a new feeling of peace and comfort in the air a reminder of not only our blessings, but the love we really did have for each other.

    “I'm grateful for being grateful!” Dora declared.

    “Me, too!” was the unanimous response.

    I don't remember the activities that took place the rest of the day. But it was a day when our family was transformed by two simple words: thank you. Since then, it's become a family motto.

    Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate  (迁徙) north.

    Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.

    According to Science Daily, a new study predicts that by the year 2100, many of today's familiar climates will be replaced by climates unknown in today's world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.

    Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn't matter what is causing it, but rather, what can be done about it. What's more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.

    However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.

    We have most friends at the age of 26 after having spent the first quarter of our lives building up our friendship circle, a new research has claimed.

    The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends.  Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.

    The research, by Forever Friends, shows that about a third of adults meet their closest friends when at school, with about a fifth saying they meet them at work.

    Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just 4.

    Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school.  It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot.  As adults we can often forget how powerful these small things are and how the little things can make a difference. ”

    Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% to drift away from childhood friends.  

    With growing pressures being put on friendship these days, it's important to make time for our friendship.

    Saving money is a golden rule in everyday life. And in the western countries it is especially obvious. As prices and building costs keep rising, the "do-it-yourself" (DIY) trend in the US continues to grow.

    "We need furniture for our living room", says John Rose, "and we just didn't have enough money to buy it. So we decided to try to making a few tables and chairs."

    John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Roses took a 2-week course for $ 280 at a night school. Now they make all their furniture and repairs around the house.

    Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe-making factory. Last month, he received a car repair bill for $420. "I was deeply upset about it. Now I've finished a car repair course, I should be able to fix the car by myself."

    John and Jim are not unusual people. Most families in the country are doing everything they can do to save money so they can fight the high cost of living. If you want to become a DIY, you can go to DIY classes. And for those who didn't have time to take a course, there are books that tell you how you can do things yourself.

    Imagine possessing something that you loved so much. Imagine what it would feel like if you lost it. While that item may be something as simple as a doll, you would still feel very upset, but you could replace it with a new one. Now imagine losing something that you depend on for survival and cannot be replaced. That is what it would be like if we lost the natural environment around us.

    Firstly, I believe the environment should be preserved because it supports human life. One of the largest examples is that we get all of our food and drinks from the environment. If the environment were to be destroyed beyond revival, then the human race would be over in months. Scientists have yet to find another planet with similar conditions to the Earth, and if it's found, we don't have the technology to get to that planet on time.

    Secondly, I believe that the environment serves as an amazing educational tool for students. When I was in second grade, I had an absolute interest in animals. When we had a field trip to the Daggerwing Nature Center, I was very excited. When we got there, I could hardly believe what I was seeing. There was a bridge to get to the main building, and under the bridge was a small swamp (沼泽) with turtles, fish, and my personal favorite, alligators. I was so surprised that I almost ran into the tour guide. We walked into the building and saw various animals in their habitats. I was so inspired by this visit. Six years later, I have taken an animal behavior class for three weeks. Meeting by chance with the environment can inspire people, and if preserved it will continue to inspire people.

    In conclusion, the environment is so valuable because it can't be replaced, keeps us alive, and serves as a great educational tool.

    What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

    In discussion of technological(技术的) changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs（器官）. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.

    It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
