w people built them hundreds and hundreds of years ago. 
built over 4,000 years ago. Each tomb has walls shaped like triangles and a square base. The largest pyramid is more than 450 feet tall and contains more than two million stones. Each stone weighs more than two tons. Some of the stones weigh as much as 200 tons. More than 900 workers worked to move the largest stones into place.
sage?“It was cool，because I got a chance to be in a studio and see how a record is made，”says 14-year-old Javon Martin，who joined the music clubhouse 3 years ago.“It has impacted my life in a big way. People are actually starting to see me as an artist.”Ten-year-old Akheylah Hunter didn’t play an instrument when she became a club member last year. Now，she plays piano and sings with the band. What she likes best，she says，is performing.“We performed in different places，”she says.“We go on trips and it is fun.”
Since the Music Clubhouse opened three years ago，it’s served almost 500 kids.Aggeler says performing in front of different audiences helps the young musicians build self-esteem.Coming to the club to prepare for those performances helps them learn how to deal with their personal problems and concerns.
“I can see what it does for them and it just develops confidence，”he explains.“It’s also an escape from the big problems we have in the neighborhood. So whether they feel embarrassed about a zit on their face，or they feel embarrassed because they’re not as tall as somebody，they can rap about it and let it out a little bit.”
To expand the club and help more kids learn music，Aggeler sought the support of the community. The Berklee College of Music and local music stores have provided free equipment. The club has also gotten support from the Music and Youth Initiative，a nonprofit that develops after school music education programs in underserved communities in Massachusetts. All these have made it possible to provide kids who may not have the means to get private music lessons the opportunity to still learn music and get all the benefits that music education brings.”

Dickson Despommier, a public health professor at Columbia University in New York City developed an idea with his students nine years ago. They imagined people in cities growing crops inside a tall building. Tomatoes could grow on one floor of the skyscraper(摩天大楼), potatoes on the next, small animals and fish on the floor above.
This vertical(垂直的) farm, or "farmscraper", could have space for restaurants and other places that serve food, like schools or hospitals. They could serve foods that are truly locally grown.
But why would anyone want to build a farm indoors in a city? Dickson Despommier believes it will become necessary. The world needs to find places to produce enough food to feed the growing population. Space, he says, is an all-important issue.
The professor also points to the problems of traditional farms. They use a lot of freshwater. Their fertilizer and animal waste can pollute water resources. And their growing seasons can be limited.
But inside the vertical farm, crops could grow all year. And there would be no wind to blow away soil. Farmers would not have to worry about too much or too little rain, or about hot summers, freezing winters or insects. And without insects there would be no need for chemicals to kill them.
Farm machines that .use fossil fuels, like tractors, would not be needed either. And water could be recycled for drinking. "The vertical farm reuses everything, so there is no waste," says Professor Despommier.
Even buildings could be saved. Old buildings could become new farms and provide jobs.
The professor has been actively proposing the idea to cities as far away as Dubai and Canada. But so far it exists only in plans and drawings, and a model at the Museum of Science and Industry in Chicago.
Critics say building a farmscraper would cost too much, especially considering the price of land in many cities. Dickson Despommier estimates the cost at about twenty to thirty million dollars.
But he says the building would not have to be very tall. And his graduate students have found many empty lots and unused buildings in New York City that could provide space.
