About five years ago I began to study at a new school, when my family moved to Iowa. I was just a little    1  ,wondering whether I could get on well with my classmates.
Lucy, a girl in my    2  , who I thought wasn’t ready to accept a  3   girl, didn’t like me from the start.    4  ,I was pretty sure she hated me. When I asked her a question, I could __5__ she thought I was a total fool.
My teacher made us   6   next to each other for the last term. Lucy was not happy. However, I kept   7   at her, though she rolled her eyes, and I kept telling her that she was beautiful.
Finally, Lucy let me   8   to her, even when her friends were around. She ___9___ telling me how beautiful I looked. I still remember the ___10___ time when she smiled at me and said that, and I smiled right back, saying    11  to her. One day Lucy invited me over to her house, and talked to me all the time   12   her other friends. That day Lucy , the girl who had hated me, called me her best deskmate. After that, we   13   friends for years.
I moved to Arizona later, but I will never   14   Lucy. I still remember she considered me her   15  at first. During that time it felt like I was    16  my time, and losing my dignity(尊严)，but I still smiled at Lucy even when she    17  me. I’m not stupid; I didn’t think she was   18   in doing those things, but I still put up with it. And finally we became great friends.
Not long ago, I read the   19   of Abraham Lincoln, “Am I not destroying my enemies when I make friends of them?” I smiled, thinking of Lucy. It just   20   me how great a friend I used to have.

About a week ago, my 4­year­old cousin and I were playing basketball at our local park. The__31__was warm, and many other children were outside__32__. As we played, I noticed a small group of boys__33__a smaller, skinnier, and possibly younger boy. They were calling him names and__34__pushed him to the ground and__35__dirt in his face. When I saw that, I grabbed my__36__by the hand and walked over to the__37__.
I stepped__38__them and the younger boy, and asked them__39__what this boy had done deserved__40__they were doing to him. They all__41__silently for a moment, and then the most amazing thing __42__：one of the boys who hadn't said anything since I__43__stepped around the younger boy and helped him off the__44__and then apologized. He offered to let him play with them，__45__the boy quietly said “thank you” and refused, and then left there.
As I looked around, I__46__that there were dozens of other people at the park—some of them were__47__with children of their own—but no one else had stopped to help this boy. I felt__48__that the one of the boys was brave enough to stand up against his friends to help someone__49__， but I felt sad that no one else had even taken a second__50__. I couldn't help but think that those parents at the park would want someone to help their child in that situation, and yet they did nothing but stood by.

When we think of green buildings, we tend to think of new ones-the kind of modern, solar-paneled masterpieces that make the covers of architecture magazines．But the US has more than 100 million existing homes, and it would be incredibly         to tear them all down and         them with greener versions．

An enormous amount of energy and resources went into the construction of those houses．And it would take an average of 65 years for the         carbon emissions (排放) from a(an) __     _ energy-efficient (节能) home to make up for the         lost by destroying an old one．

So in the broadest sense, the greenest home is the one that has already been built．But at the same time,          half of US carbon emissions come from heating, cooling and powering our          , offices and other buildings．"You can't deal with climate         without dealing with existing buildings," says Richard Moe, the president of the National Trust．

With some exceptions, the oldest homes tend to be the         energy-efficient．Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that         over time and let in more outside        .

      ,there are a vast number of relatively simple changes that can green older homes, from        ones like Lincoln's Cottage to your own postwar home．And efficiency upgrades (升级) can save more than just the earth; they can help         property owners from rising power        .

This year, about 2,300 teenagers from all over the world will spend about 10 months in US homes. At the same time about 1,300 American teenagers will go to other countries to learn new languages and learn the rest of the world.

Here is a 2-way student exchange in action. Fred, 19, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.

Fred, a lively young man, knew little German when he arrived. But after 2 months of studying, the language became easy for him. School was completely different from what he had expected and it was much harder. Students rose respectfully when the teacher entered the room. They took 14 subjects instead of 6 that were usually taken in the US.

Family life, too, was different. They have to listen to their fathers. All the activities were done with the family rather than individually. Fred found the food to be too simple at first. He also missed having a car.

“Back home, you pick up some friends in a car and go out to have a good time. In Germany, you walk but you soon learn to like it. ”

At the same time, in America, Mike, a friendly German boy, was also forming his own ideas. “I suppose I should criticize American schools. ” he says, “It is far too easy for our level but I have to say that I like it a lot in Germany, we do nothing but study. Here we take part in many other activities. I think that maybe American schools are better in training their citizens. There ought to be some middle ground between the two.

__1____ between American school life and German school life

People think children should play sports. Sports are fun, and playing with others. However, playing sports can have __1   effects on children.

Of these, 18,000,000 say they have been __2   at or called names while playing sports. This leaves many children with a bad __3  ^{of sports. They think sports are just too aggressive.}

This behavior is then further strengthened through both positive and negative feedback. Parents and coaches are powerful teachers because children usually look up to them.

Many parents go to children's sporting events and shout __7 _ at other players or cheer when their child behaves __8__. As well, children arc even taught that hurting other players is _ 9 or are pushed to continue playing even when they are injured _10 , the media makes violence seem exciting. Children watch adult sports games and see violent behavior replayed over and over on television.

They should not just cheer when children win or act aggressively. They should teach children to __14 _ , themselves whether they win or not.
