题目分析:(1)人体所需的六大营养元素有:蛋白质、糖类、脂肪、维生素、水和无机盐.由图示可知,图中可知水和维生素未被规定强制标示.故答案为:维生素.(2)食物所含的六类营养物质中,能为人体提供能量的是糖类(碳水化合物)、脂肪(或油脂)、蛋白质,同时这三类物质也是组织细胞的组成成分.故答案为:糖类(碳水化合物)、脂肪(或油脂)、蛋白质.(3)在奶制品中或在人体内,钙是以无机盐的形式存在的,这里的钙是指盐中含有的钙元素;儿童缺钙会患佝偻病,所以儿童每日要摄取足够量的钙,才能避免佝偻病.故答案为:元素;B.(4)有机合成材料简称合成材料,主要包括塑料、合成纤维、合成橡胶三类,所以B塑料桶属于合成材料;铁罐、塑料桶、玻璃瓶都是可回收物品.

     I grew up poor, living with my wonderful mother. We had little money but plenty of love and attention.  
I was   1   and energetic. I understood that no matter how poor a person was, he could still   2   a dream.
My dream was to be a sportsman.   3   I was sixteen, I had started playing baseball. I could throw a
ninety-mile-per-hour fastball and hit anything that moved on the football field.  I was also   4  : my
high-school coach was Ollie Jarvis, who not only believed in me, but taught me  5  to believe in myself.  
He   6   me the difference between having a dream and realizing the dream. One particular   7   with Coach
Jarvis changed my life forever.
     It was the summer between my junior and senior years, and a friend recommended (推荐) me for a
summer job. This meant a chance for money in my pocket-money for a new bike and new clothes, and
the   8   of savings for a house for my mother. Then I realized I would have to   9 summer baseball to deal
with the work schedule, and that meant I would have to tell Coach Jarvis I wouldn't be playing.  
     When I told Coach Jarvis, he was as   10   as I expected him to be.  "You have your whole life to
work," he said.  "Your playing days are limited. You can't   11   to waste them." I stood before him with
my head hanging, trying to think of the   12   that would explain   13   him why my dream of buying my
mom a house and having money in my pocket was worth facing his   14   in me.
     "How much are you going to make at this job, son?" he asked. "Three twenty-five an hour," I replied.
"Well," he asked, "is $3.25 an hour the   15   of a dream?"
     That simple question made it   16   to me the difference between   17   something right now and
following a dream. I   18   myself to sports that summer, and within the year I was  19   by the Pittsburgh
Pirates to play baseball, and was   20   a $20,000 contract. In 2000, I bought my mother the house of my
dream!
