成就一位科学家，因为一个科学家最突出、最基本的特点是应具备自我约束能力。

　　1．The first paragraph tells us that the author ________ .

　　A．lost his hearing when he was a child

　　B．didn't like his brothers and sisters

　　C．was interested in flowers and insects in his childhood

　　D．was born to a naturalist's family

　　答案：C推理判断题。第一段第一句中的"... convinced that

　　naturalists are born and not made"表明作者认为博物学家是天生的，不是后天造就的。由关键信息"my brothers and sisters soon abandoned ... flowers and insects"可知，他的姐妹兄弟对于花、虫等不感兴趣，但作者不像他们(Unlike them)，由此推知作者在童年时对花草是感兴趣的。故选C项。

　　2．According to the author, a born naturalist should first of all be ________ .

　　A．full of ambition B．self－disciplined

　　C．full of enthusiasm D．knowledgeable

　　答案：C推理判断题。从第三段第一、二句"I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into varied investigations."可知，作者认为一个博物学家首先应具备的是对自然界的热爱之情，故选C项。

　　3．The author says that he is a naturalist rather than a scientist probably because he thinks he________ .

　　A．just reads about other people's observations and discoveries

B．lacks some of the qualities required of scientists
