At most school, “going green” means less rubbish or recycling. But at New York’s Riverdale Country School, it means being advised to run and even jump in the hallways. And the students really enjoy doing that.

Why? It because the hallways were built with special kinetic(动能的)tiles. When students run or jump on the floor tiles, electricity will be generated(产生). The electricity can be used to power classroom lights, science projects and charge electronic products. 14-year-old Zach Halem tried to make the officials buy them. There are eight tiles near the school’s student center.

Besides providing fun green energy, it’s also a good way to teach the students to be creative. They will be inspired to be scientists, inventors and engineers in the future to find clean energy for all humans.

The tiles are mostly made from rubber and other recycled things. They were invented by an English man Laurence Kembell-Cook. While new to the US, They have been put in many places in Europe- from a London Underground Station during the 2012 Olympics to a marathon (马拉松)track in Paris. When Pavegen started getting popular in London schools, Laurence began to realize that his invention not only saved energy ,but was also fun!

Do you want to be successful in everything you do? If so, then ? Here is an example.

There was a farmer who corn (玉米) all his life. Each year he took his corn to the market. Then each time his corn was chosen as the and won the first prize.

One year a newspaper reporter interviewed him and learned something about how he grew it. The farmer his seed(做种子的) corn to his neighbors.

"How can you share your best seed corn with your neighbors?" the reporter asked. "You know they are taking part in the with you each year."

"Why, sir," said the farmer, "didn't you know? The picks up pollen (花粉) from the corn and moves it quickly from field to field. If my neighbors grow corn, cross-pollination (异花传粉) will affect the quality of my corn. So if I want to grow good corn, I must my neighbors to grow good corn. "

The farmer knows much about the connection of life. His corn cannot improve his neighbor's corn improves.

As a great man says, "We make a living by what we ; we make a life by what we give." We can't without food, clothes, and many other things. However, a meaningful life is not decided by how much we can get, by how much we can give others. Giving, instead of taking, makes us from other animals.

So those who choose to live well must help others to live well and those who choose to be happy must help others to find in their life.
