完形填空。 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 1 . He loved to read and often needed to 2 the books he'd read in order to borrow more books. One unintended 3 of his nonstop reading habits was that he even 4 at the dinner table. His mother, Mary, and I did our best to 5 him that, on certain social 6 , reading while dining with others was not a good thing. Every summer the teachers at his school 7 give the students a reading list, and there was a contest to see who could read the most books. He was so 8 , and he always wanted to win. And he often 9 . But the main reason why he read so obsessively (着迷地) was that he was so 10 . He didn't just want to learn about 11 things. He wanted to learn about everything. We helped 12 his curiosity in every way. 13 an unfamiliar word came up in conversation, we'd turn to the 14 , looking up the word, and reading the definition aloud. Thus my son came to realize that if you have a question, the 15 exists somewhere. All you have to do is 16 it. Bill remains as much of a 17 today as when he was a child, and he seems to 18 everything he reads. He's often 19 to share what he's learned with the next person he meets. He 20 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 .
