As a kid, I spent my summers with my grandparents in Texas. And every few summers, we’d     16     the caravan (旅游团队), a group of Airstream trailer owners who     17     together around the U.S. and Canada．
I loved and worshipped my grandparents and I really looked     18     to these travels. On one particular      19     ，I was about 10 years old. I was rolling around in the backseat. My grandfather was     20     . And my grandmother had the passenger seat. She smoked throughout these trips, and I hated the     21    .
At that age, I’d take any excuse to make estimates(估计) and do minor     22    ．At any rate, I decided to do the math for my     23    . I estimated the number of  cigarettes per days, estimated the number of     24     per cigarette and so on. When I was satisfied that I’d e up with a reasonable number, I poked my head  into the     25     of the car, tapped my grandmother     26     the shoulder, and proudly proclaimed, “At two minutes per puff, you've taken nine years off your     27    !” Because the ad said, every puff of a cigarette takes some  number of minutes     28     smoker’s life．
I expected to be applauded for my     29     and arithmetic skills. That’s not what happened．    30    , my grandmother burst into     31    . I sat in the backseat and did not know what to do. My grandfather was a highly intelligent,     32     man. He had never said a harsh word to me. He pulled     33     onto the shoulder of the highway. He stopped and got out of the car,     34     me, and after a bit of silence，he gently and     35     said, “Jeff, one day you’ll understand that it’s harder to be kind than clever.”
