【回答】

41．a；考查不定冠词，这里用不定冠词a表泛指，a healthier life意为"一种更健康的生活"．        

42．their；考查形容词*物主代词，分析句子结构可知，此处用形容词*物主代词作定语，修饰名词health，意为"他们没有太多时间来顾及他们的健康"．     

43．that；考查强调句，这是"It is/was+被强调部分+that/who+其他部分"的强调句型．    

44．given；考查非谓语动词，这里过去分词形式given作后置定语，修饰名词suggestion．    

45．is；考查主谓一致，动名词短语 eating green vegetables and fruits 做主语，谓语动词用单数形式．  

46．that/which；考查关系代词，这是一个定语从句，现行词为 lots of vitamins and minerals，故用关系代词that/which在从句中作主语．

47．regularly；考查副词，此处用副词作状语修饰动词  exercise．

48．weight；考查名词，这里名词weight用在介词of之后，构成介宾结构．   

49．to make；考查动词不定式，此处不定式表示目的．   

50．saying；考查分词作状语，主语many people 与动词say存在逻辑上的主谓关系，故用现在分词形式作伴随状语．
