题型：不详难度：来源：

Looking back on  my childhood, I am convinced that naturalists are born and not made.  Although we were all brought up in the same way,my br others and sisters soon abandoned 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 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 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 had led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil 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 honor 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 of the outstanding  and essential qualities required is selfdiscipline, a quality I lack. A scientist, up to a certain point,can be made. A naturalist is born. If you can combine the two,you get the best of both worlds.

答案

1-4  ADAB

解析

1.  第一段告诉我们，童年的作者对花和昆虫感兴趣。作者在第一段说“Although we were all brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects.”此句暗示作者自己则坚持了下来。因此A为正确答案。B、C和D的内容与本文无关。
2.   因为他把注意力全放在观察自然上了。第二段最后一句明确说明了这一问题的原因。
3.   作者既是一位博物学家，也是一位科学家。这一点可从第三段最后一句推测而出。作者称自己不是一位科学家是在谦虚。D不对，B和C为文中的明确表述，而不是推测的结果。
4.   作者在最后一段指出“:one of the outstanding and essential qualities required is self|discipline, a quality I lack”，由此可知B为正确答案。
