Answer 1

51．annoying  考查非谓语动词．分析句式可知，it是形式主语，真正的主语是 that you can't eat whatever…不能吃自己想吃的东西似乎很令人恼火，故填现在分词．
52．her   考查代词．此处her代指的是你的妈妈，符合上下文语境．
53．were suffering/suffered 考查时态．根据前面的时间状语 According to China News，in 2010，可知叙述的是2010年的事情，故用一般过去时．或者根据Meanwhile在此期间，人们一直遭受着高血压和糖尿病的折磨，可以使用过去进行时，即were suffering表示过去一段时间内一直持续的动作．
54．closely  考查副词．此处用来修饰短语be closely associated with 意思是紧密的关系，closely是副词，紧密地，密切相关地．
55．a  考查冠词．researcher at the National Institute 此处是泛指一个研究人员，故用a．
56．why 考查连接词．根据上一段的内容可知，这些主要的威胁公众健康的因素是和食品消费有密切的关系，所以政府出台一些指南．
57．to promote  考查动词不定式．结合句意可知，to  promote…是动词不定式表示目的．
58．published   考查非谓语动词．分析句式可知，The guidelines1和publish之间是被动关系，故用过去分词表示被动．
59．and 考查连接词．根据句意可知，and连接两个并列句．
60．what考查连接词．分析句式可知，what should your daily diet be exactly like？like是介词，缺少宾语．
