16.useuse解析：后面的一句话“Theexpressionis‘both-feet-on-the-ground.”表示down-to-earth的另一种表达方法是both-feet-on-the-ground。而后一种说法是美国人的用法，常常被美国人使用。故答案为use。

17.threatenthreaten解析：由33题解析可以知道此空一定为“威胁”之意。

18.tastetaste解析：本句意为“我们看得见它，闻得见它，…它，喝它，而且在它中间挣扎。”由常识可知，此空处只有一个“尝”较合适。

19.withwith解析：根据对等关系，这里应该与后面的部分“apersonwithagoodunderstanding”相对应。意思是“那些脚踏实地的人往往是那些很了解现实的人。”故答案为with。

20.atat解析：某大学的教授，应为“aprofessorat…university”，所以答案为介词“at”。

21.especiallyespecially解析：“Around
