    Picture this scene. You wake up on a school morning, and you know you're 1. Maybe your throat is sore. Maybe your head hurts. Whatever the 2 is, your mum or your dad sends you back to bed to rest. This 3 to every kid once in a while, right?

    Wrong. And the living proof (证据) is eighteen-year-old Travis Schmidt. From his first day of kindergarten (幼儿园) to his last day of high school, Travis 4 stayed home sick. At first, Travis didn't think too much about never being absent (缺席的). But then he reached third grade with perfect attendance (出勤率). At that point, Travis decided to see how 5 he could keep it up.

    So how did Travis successfully keep 13 years of perfect attendance? In the first place, he's a very heathy kid. Although he got colds like everyone else, Travis never felt sick enough to stay home. Travis also 6 ahead (提前地). For example, he knew he'd 7 get chickenpox (水痘) sooner or later. So when a friend caught chickenpox one summer, Travis made sure to 8 him. A few days later, he was covered with poxes. But he had quite a lot of 9 to get better before school started in autumn.

    Travis is 10 his record. "I may not be the smartest or the coolest. But I'm always there," he says.

人有许多血型系统，如ABO血型、MN血型等．研究表明，人的ABO血型不仅由位于9号染色体上的I^A、I^B、i基因决定，还与位于第19号染色体上的H、h基因有关．在人体内，H物质在I^A基因的作用下，形成凝集原A；H物质在I^B基因的作用下形成凝集原B；而ii的人不能转变H物质．其原理如图所示：
