58．我确实很欣赏你的演讲，虽然有些部分我不是很理解．
59．食物安全是很重要的，必须制定法规来阻止食品污染．
60．对不起，我没听懂你说的话，你可以说的更清楚一点吗？
解答 56．fifth．我们知道周日是一周当中的第一条，所以周四是一周当中的第五天，所以要用five的序数词fifth．
57．costs．but是并列连词，连接并列的部分，but后面的部分是谓语动词+宾语，所以空格处也需要一个动词来作谓语，结合but后面的时态是一般现在时，主语是smile，所以要用cost的一般现在时形式costs．
58．though．though意思是"尽管，虽然"，引导让步状语从句，虽然存在某种状况，但是不妨碍另一种状况的发生．尽管有些部分我不是很理解，我还是很欣赏你的演讲，所以要用though来填空．
59．safety．根据后半部分"Rules must be made to stop people from food pollution．"必须制定法规来阻止食品污染，因此可知食品安全很重要的．故填safety．
60．clearly．根据前半部分"I can't follow you．"我没听懂你说的话，所以要求对方说的更清楚一些，所以要用clearly来填空．
点评 首先要掌握句子的意思，然后结合具体的题目以及给出的英语提示，就可以确定正确答案．
