分析 作者在本文告诉我们健康的饮食和适当的锻炼对人，尤其是青少年是非常有益的．

解答 61．to become；考查固定结构．the first step  to  do sth 为固定结构，意为做某事的第一步，故填 to become．
62．it；考查代词．句意为给你的身体它必须的能量．根据句意可知代词it符合语境，故填it．
63．from；考查固定结构．protect  sb from…为固定结构，意为保护某人不受，故填from．
64．A；考查固定搭配．A number of 为固定搭配，表示很多，此处表示很多人．故填A．
65．believing；考查动名词．空格前是介词into，所以后面是动名词做宾语，构成动宾结构．故填 believing．
66．on which；考查定语从句"介词+关系代词"在从句中主要起关系副词的作用，即在定语从句中充当状语．介词on来自于后面的 depend，故填on which．
67．beneficial；考查形容词．由前面的is可知此处应该填一个形容词，故填 beneficial．
68．strength；考查名词．由前面的the可知，此处应该填名词，所以填strong的名词形式strength，故填strength．
69．relaxed；考查动词的ed形式．用动词的ed形式修饰人，ing 形式修饰物，此处是修饰人，故填relaxed．
70．and；考查连词．按照上面的建议和后句你在任何时间都会感觉更好，两句之间是并列关系，故填and．
