阅读下列短文，从每题所给的四个选项中选出最佳选项。

　　Looking back on my childhood，I get to believe that naturalists are born and not made．Although we were all brought up in the same way，my brothers and sisters soon threw away their pressed flowers and insects．Unlike them，I had no ear for music and languages．I was not an early reader and I could not do mental arithmetic．

　　Before War I we spent summer holidays in Hungary．I have only the unclear memory of the house we lived in，of my room and my toys．Nor do l recall clearly the large family of grandparents，aunts，uncles and cousins who gathered next door．But I do have a clear memory of the dogs，the farm animals，the local birds and，above all，the insects．

　　I am a naturalist，not a scientist．I have a strong love of the natural World，and my enthusiasm（热情）has led me into varied investigations（调查）．I love discussing my favorite topics and enjoy burning the midnight oil while reading about other people's observations and discoveries．Then something happens that brings these observations together in my conscious mind．Suddenly you wonder you see the answer to the riddle（谜），because it all seems to fit together．This has resulted in my publishing 300 papers and books， which some might honour with the title of scientific research．

　　But curiosity（好奇心），a keen eye，a good memory and enjoyment of the animal and plant world do not make a scientist；one of the outstanding（杰出的）qualities required is self-discipline，a quality I lack（缺乏）．A scientist requires not only self-discipline but hard training， determination and a goal．A scientist，up to a point，can be made．A naturalist is born．If you can combine（联合）the two，you get the best of both worlds．

　　Benjamin Banneker was born a few months before another great American —George Washington. Benjamin was black, but he was not a slave. He and his mother and his grandmother were free.

　　Benjamin's grandmother came from England. In America she got a job and worked for many years to pay for her boat trip across the ocean. After working many more years, she saved enough money to buy a farm. Benjamin lived with her for a while. She taught him to read and write and do arithmetic.

　　Benjamin's neighbors knew that he was clever. They were not surprised when he built a large wooden clock. He made each piece after studying a small pocket watch. The clock made him famous, for it was one of the first clocks built in America. People from other places began to send hard problems of all kinds for Benjamin to settle.

　　Thomas Jefferson learned of Benjamin Banneker's ability to settle hard problems. He asked Banneker to help build the city that was to be the capital of the United States —Washington, D.C..

　　Banneker worked hard on the plans for the city. He marked where the streets and buildings —the Capitol (国会大厦), the White House, and many others —should be built.

　　Later, L' Enfant, the Frenchman who had designed the new city, had a quarrel, and went back to France in anger. He took all of the plans with him. The workmen couldn't build without any plans to follow.

　　For a while it seemed that the plans for the capital might have to be changed. But Benjamin Banneker remembered the plans he has helped draw. He drew each again just as he once has built each piece of his clock.

　　If it weren't for Benjamin Banneker, Washington, D.C.might look very different from the way it does today.
