学校要举行运动会,班上几位班干部商量给运动员准备一些补充能量的食品,甲说买巧克力,乙说买牛肉干,丙说买水果,丁说买牛奶.请问那位同学说的最实用(  )

A.甲

B.乙

C.丙

D.丁

答案

食物所含的六类营养物质中,能为人体提供能量的是糖类、脂肪和蛋白质;糖类是人体最重要的供能物质,人体的一切活动,包括学习、走路、消化和呼吸等所消耗的能量(约70%)主要来自糖类,脂肪是人体内备用的能源物质,蛋白质是构成人体细胞的基本物质,水、无机盐、维生素不为人体提供能量.据此可知,巧克力含丰富的糖类,能快速的提供能量.牛肉干、牛奶含蛋白质丰富,水果主要提供维生素和部分无机盐.可见A符合题意.

故选:A

There are stories about two US Presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK. We don't know if either story is true,but they are both interesting.

The first explanation is based on the fact that President Jackson had very little education. In fact,he had difficulty reading and writing. When important papers came to Jackson,he tried to read them and then had his assistants explain what they said. If he approved of a paper, he would write “all correct” on it. The problem was that he didn't know how to spell. So what he really wrote was “ol korekt”. After a while,he shortened that term to “OK”.

The second explanation is based on the place where President Van Buren was born,Kinderhook,New York. Van Buren's friends organized a club to help him become president. They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called “OK”.
