Childhood curiosity can last a lifetime and I learned this from my son, Bill. When he was very young, I often took him to the      . He loved to read and often needed to        the books he’d read in order to borrow more books. One unintended          of his nonstop reading habits was that he even      at the dinner table. His mother, Mary, and I did our best to        him that, on certain social          , reading while dining with others was not a good thing.

Every summer the teachers at his school      give the students a reading list, and there was a contest to see who could read the most books. He was so        , and he always wanted to win. And he often        . But the main reason why he read so obsessively (着迷地) was that he was so      . He didn’t just want to learn about        things. He wanted to learn about everything.

We helped      his curiosity in every way.     an unfamiliar word came up in conversation, we’d turn to the   , looking up the word, and reading the definition aloud. Thus my son came to realize that if you have a question, the      exists somewhere. All you have to do is        it.

Bill remains as much of a   today as when he was a child, and he seems to          everything he reads. He’s often        to share what he’s learned with the next person he meets. He        reads at the dinner table, though — which is a good thing because the books he’s attracted to now are increasingly unappetizing (引不起食欲的): The Eradication of Infectious Diseases, Mosquitoes, Malaria & Man, and Rats, Lice, and History.
