12．There are many people who say Thomas Edison invented the twentieth century．Although there are those who may disagree，yet Edison was one of the greatest inventors in America．
Born in 1847 in Ohio，Thomas Edison attended school for only three months．After his teacher said that he could not learn，Edison's mother decided to teach him at home．There he was allowed to study the subjects that most interested him．By age ten，Edison had built a science laboratory of his own．
Edison got his first job at age twelve on the railway selling candy and newspapers．There he once saved a boy whose father was the boss of the railway station．In return the boss helped him a lot．
In his late twenties，Edison built an"invention factory"where he and his business partners could devote all their time to inventing．After improving upon the telephone，Edison created the phonograph（留声机）．Although Edison did not actually invent the light bulb，he did create an electric lighting system which led to its widespread use．
Edison set up the first central electric power station in 1882，so New York became the first city in the world to have electric lights．This was the beginning of the modern world in which electricity became a way of life．
The following year，one of Edison's engineers discovered electrons（电子），which at last led to electronics．Without electronics，we might not have radio，TV，computers，or space travel．The rest of Edison's life was spent making and improving inventions．
Thomas Edison died at the age of eighty-four in 1931．Three days later，much of America dimmed（使暗淡） its lights in honor of the inventor-a man who had more influences on the development of present-day civilization than anyone else in history．

11．China is a land of bicycles．At least it was back in 1992 when I traveled the country．Back then everyone seemed to be riding a bicycle．Millions of them，all black．Cars were rare．Yet since my arrival in Beijing last year，I've found the opposite is true．There are millions of cars．However，people still use their bicycles to get around．For many，it's the easiest and cheapest way to travel today．Bicycles also come in different colors-silver，green，red，blue，yellow，whatever you want．
It's fun watching people biking．They rush quickly through crossroads，move skillfully through traffic，and ride even on sidewalks （人行道）．Bicycles allow people the freedom to move about that cars just can't provide．
Eager to be part of this aspect of Chinese culture，I decided to buy a bicycle．Great weather accompanied my great buy．I immediately jumped up on my bicycle seat and started home．
My first ride home was orderly （守秩序的）．To be safe，I stayed with a"pack"of bikers while cars on the streets came running swiftly out of nowhere at times．I didn't want to get hit．So I took the ride carefully．
Crossing the streets was the biggest problem．It was a lot like crossing a major highway back in the United States．The streets here were wide，so crossing took time，skill and a little bit of luck．
I finally made it home．The feeling on the bicycle was amazing．The air hitting my face and going through my hair was wonderful．I was sitting on top of the world as I passed by places and people．Biking made me feel alive．
