Do you want to make your own bike？You can do（46） 　　at the Bamboo Bike Studio （竹子单车工作室） in New York．People can learn（47） 　　to make their own bamboo bikes there．

The studio is also helping build factories in Ghana （加纳），a country in western Africa．The factories will make cheap bamboo bikes．

Bamboo grows in America．It also grows everywhere in Ghana．Bamboo is one of the fastest﹣growing（48） 　　in the world．

Bamboo is as good as steel for（49） 　　a good bike．Marty Odlin works at the studio．He says a bamboo bike is the wonderful everyday bike．

In Ghana，bikes are very popular，because（50） 　　people have money to buy a car．They have to use bikes to（51） 　　most of the country's food and other goods （商品）

The people of Ghana are also too（52） 　　and they can't build factories to make traditional steel bikes．（53） 　　making bamboo bikes is cheap．Odlin plans to teach Ghanian workers how to（54） 　　make bamboo bikes．He says each worker can make about four bikes a day．

"Tn America，we have too many goods，"says Odlin．"So we don't appreciate （感激） what we have．In Ghana，people don't have many goods．We want people in America to have a better relationship with their goods and（55） 　　in Ghana to have more goods．"
