As kids, my friends and I spent a lot of time out in the woods,"The woods" was our part-time address, destination,purpose,and excuse.If I went to a friend's house and found him not at home,his mother might say, "Oh,he's out in the woods,"with a tone of airy acceptance.It's similar to the tone people sometimes use nowadays to tell me that someone I'm looking for is on the golf course or at the gym,or even "away from his desk."For us ten-year-olds,"being out in the woods" was just an excuse to do whatever we feel like for a while.

    We sometimes told ourselves that what we were doing in the woods was exploring.Exploring was a more popular idea back then than it is today.History seemed to be mostly about explorers.Our explorations,though,seemed to have less system than the historic kind: something usually came up along the way.Say we stayed in the woods, throwing rocks,shooting frogs,picking blackberries,digging in what we were briefly persuaded was an Italian burial mound.

    Often we got "lost" and had to climb a tree to find out where we were.If you read a story in which someone does that successfully,be skeptical: the topmost branches are usually too skinny to hold weight,and we could never climb high enough to see anything except other trees.There were four or five trees that we visited regularly—tall beeches,easy to climb and comfortable to sit in.

    It was in a tree,too,that our days of fooling around in the woods came to an end.By then some of us had reached seventh grade and had begun the rough ride of adolescence.In March,the month when we usually took to the woods again after winter,two friends and I set out to go exploring.We climbed a tree,and all of a sudden it occurred to all three of us at the same time that we really were rather big to be up in a tree.Soon there would be the spring dances on Friday evenings in the high school cafeteria.

    When I came to Cincinnati as an au pair (家庭打工留学生), a lot of things there were different from what I knew. My host family lived in a huge house I could only describe as a "castle"．In Germany I had lived in a small apartment together with my mom. Soon I found out that the "castle" was actually rather small in our neighborhood.

    Everybody there was very friendly and polite. They greeted you when they were walking by at least 3 feet away from you. They must not have seen a German au pair before, for most people I met asked me all kinds of questions about Germany. I enjoyed answering their various strange questions. I made a lot of friends and I started to hang out with them.

    Of course, there were a number of new things, and it took me the whole year to find them all out. I never got homesick. Perhaps it was because I did not have too many negative experiences and felt loved and welcomed there.

    However, I had undergone some painful experience back in Germany. I was frustrated by the way people would run me over and not even say "Sorry." Taking up my studies at the TU-Dresden, I felt lonely. Everybody here seemed to be withdrawn(离群的) and I missed everything I had in Cincinnati. Germany was so "cold". I found it so much harder to make new friends. After six months I got a roommate and only two good friends. I also flew back to Cincinnati several times for long periods. I felt that without those visits I was not able to make it.

    Now I am over this German culture shock. It almost took me an entire year. I am still going back and forward between Dresden and Cincinnati four times a year.

    Every so often, mankind comes up with really good inventions that have changed our daily lives. However, the U.S. Patent Office has issued over 7. 5 million patents, and not all of them are quite so celebrated. Some good, some bad, and some crazy! The following lists some of the more unusual ideas that have come along.

    Snake Leash

    In 2002, a patent was issued for a snake-walking leash. There are at least two major problems with this idea.  1) Dog leashes fit securely between the head and shoulders. A snake does not have shoulders; so it might slither away. 2) Dogs are OK for public places because they are social animals, and people like them. Snakes are not OK for public places because they are not social, and some people are terrified of them.

    Stadium Helmet

    Americans are known for our love of sports. Unfortunately, good tickets to games are expensive, and some fans have to sit in the nosebleed sections. This invention, patented in 2000, is designed for these fans.  Featuring a built-in radio, binoculars(望远镜) , a cooling fan,  and a helmet for falling litter, this design transforms the stadium experience.

    Bacon Alarm Clock

    When you think about it, waking to the dreadful, blaring noise of an alarm clock is a terrible way to start the day. However; this clock could change that. You simply put a piece of frozen bacon in the alarm clock, set the alarm, and go to sleep. The clock gently wakes you up with the mouthwatering smell of bacon the next morning, just like waking up on a Sunday morning to the smell of Mom cooking breakfast. Who said there's no time to eat breakfast?

    Toilet Lock

    In 1969, a patent was issued for a really bad idea – the toilet seat lock. First of all, fishing for your keys when you have to go seems very unpleasant. Then there is the possibility of losing the key altogether. What about guests? Just think that you would have to ask permission for the bathroom. Of course, there is the ultimate question: Why would you lock it in the first place?

    Humana Bird Feeder

    People have always admired the gracefulness and beauty of birds, and bird watching is a popular hobby. Unfortunately, getting up close and personal is a challenge. That is, until now.  In 1999, a patent was issued for a helmet with birdfeeders attached to it. Although there may be a design flaw (缺陷) (turning the head to see the birds would probably frighten them), this invention could change the way of bird watching.

    Both are so much related to each other. And both are so dissimilar! What are the differences between friendship and love? Is platonic (理想的) friendship possible between persons of opposite sex? Let us try and understand.

    What is friendship? Why do we call a person our friend? When do we call someone a very good friend? If we care for a person, if we are always ready to help that person and if we share most of our thoughts with a person, they are our good friends. We can always count upon our good friends in an emergency. We are always sure that our friend will understand why we acted in a certain way. We need not explain anything to our very good friends. The friendship is so deep and the relationship is so close.

    What about love? In a relationship of deep love, all the sharing that we discussed above are taken for granted. But love transcends (胜过) all this. During love, we are attached with a particular person, while in friendship, one may have many friends. A loving relationship makes one so much attached to the other, that one gets pained if his/her beloved is hurt! Love also involves a physical element. Friendship does not have that. This is a vital difference. Nature gives us love but does not give us friendship.

    Your heart beats will never increase in expectation of meeting your friend. You will not lie awake at night thinking about your friend. You will not feel totally lost, if you don't meet your friend for a few days. You will not have dreams in your eyes thinking about your friend. But in love, you will do all this and much more. Indeed, there is no comparison between love and friendship.

    These days a green building means more than just the color of the paint. Green buildings can also refer to environmentally friendly houses，factories，and offices.

    Green building means "reducing the effect of the building on the land"，Taryn Holowka of the US Green Building Council (评议会) in Washington，D.C.，said. According to Holowka，building accounts for 65 percent of total US electricity use.

But green buildings can reduce energy and water use. Also，the buildings are often located near public transportation such as buses and subways，so that people can drive their cars less. That could be good for the environment，because cars use lots of gas and give off pollution. Green buildings are often built on developed land，so that the buildings don't destroy forests.

    Marty Dettling is project manager for a building that puts these ideas into action. The Solaire has been called the country's first green high-rise building. According to Dettling，"We've reduced our energy use by one-third and our water by 50 percent."

    The Solaire cuts energy in part by using solar power. "On the face of the building we have solar panels (光板) which change the sun's energy into electricity，" Dettling explained.

    The Solaire also has lights that automatically turn off when people leave the room. In addition，the building has lots of windows，allowing people to use the sun for light during the day. The Solaire cuts water by reusing it.

    Not everyone is eager to move into a green building，however. Some people think that things like solar panels cost more money than more traditional energy sources. Anyhow，Holowka said，"It's going to be big."

From a young age, Michael Platt loved two things: the Rev. Martin Luther King, Jr. and cupcakes. He imagined ways he too could fight for justice. He memorized figures about income inequality and childhood hunger. But he also spent afternoons at his home computer, amazed by YouTube bakers who made perfect cupcakes.

When his parents gave him a pair of Toms shoes for Christmas three years ago, Michael saw a way to connect his twin passions. At age 11, he founded a bakery that operates on the Toms one-for-one model: For every cupcake, cake or cookie that Michael sells, he donates another to the homeless and hungry. Twice a month, he heads to locations to pass out goodies. Michael, now 13, said he especially enjoys handing out cupcakes to kids.

"I know I like cupcakes, but also cupcakes are part of a child's childhood so they should get them," said Michael, noting that he always eats one with whippedicing (打发的糖霜) on his birthday.

Michael calls his baking business Michaels Desserts. He left out the apostrophe (撇号) as a reminder that he is baking for others, not himself. "I always wanted to have a purpose for what I do." he said. "It's all about helping people— not just having a purpose for yourself, but thinking about, 'How does this touch other things? "

When he started the bakery, he knew that he wanted his business to do more than make money. That's why the intention of Michaels Desserts is fighting hunger and giving back, which Michael accomplishes through his giveaways. Michael hopes his cupcakes inspire others to work for social equality.

Sometimes, Michael admits, he grows tired of being in the kitchen. Then he remembers the homeless boy he met once while handing out cupcakes. A couple of days afterward, the boy's father messaged Michael on Facebook to say that his son, encouraged by Michael's example, now desired to become a baker.

"That inspired me," Michael said. He smiled and looked down.
