第1题
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystalclear 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 had led me into varied investigations. 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 fancy you see the answer to the riddle, 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, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one the outstanding and essential qualities required is se]f-discipline, a quality I lack. 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 the two, you get the best of both worlds.

A．was interested in flowers and insects in his childhood

C．didn't like his brothers and sisters
