单选题
Looking back on my childhood, I am convinced that naturalists are born and not made.

I was not an 28 reader and I could not do mental arithmetic. Before World War I we spent our summer holidays in Hungary. I have only the 29 memory of the house we lived in and of my room and my toys. But I do have a crystal-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 30 had led me into varied investigations. I love discussing my 31 topics and enjoy burning the midnight oil while reading about other people's observations and 32 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 33 together. This has resulted in my publishing 300 papers and books, which some might 34 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. A scientist requires not only 35 but hard training, determination and a goal. A scientist, up to a point, can be made. A naturalist is born. If you can 36 the two, you get the best of both worlds. A. combine B. connect C. serf-discipline D. enthusiasm E. regulations F. discoveries G. dim H. eventually I. abandoned J. honor K. disposed L. modest M. favorite N. early O. perfectly
问答题
【正确答案】I

问答题
【正确答案】N
【答案解析】此处需要元音开头的形容词作定语。以元音开头的只有early，根据and后面的“不会做心算”也可进一步确认。not an early reader意为“不是很早就学会阅读的人”。abandoned一词虽然也以元音开头，而且也可充当形容词，但在词义上不符合上下文的要求。
