　　答案及解析

　　31.someone 【解析】由本文的第一句话“‘Down-to-earth’means some—one or something that is honest，realistic and easy to deal with.”可知“Down—to—earth”指的是诚实，现实、平易近人的那些人。这里的someone和后面是相对应的。故答案为someone。

　　32.to【解析】talk to的意思是“和某人聊天”，talk这里不及物动词，后面需要接一个介词。在从句中介词不能省略。作者这里要表达的意思是“和那些诚实的平易近人的人聊天是很惬意的。”故答案为to。

　　33.opposite 【解析】从文章第二段的内容可以看出，A down—to—earth person和那些表面上装的很重要的人物正好相反。所以这里应填“相反的”，故答案为opposite。

　　34.important 【解析】从本句后面的一句话可以看出，A down—to—earth person就算是重要的人物，他们也不会把这种显赫写在脸上。所以前面应填important。故答案为important。

　　35.go 【解析】go to one’s heads的意思是“展现、表现”，俗语。用在文中表示“把…写在脸上”，生怕别人不知道的显摆。故答案为go。

　　36.those 【解析】本句的意思是“他们不认为自己比别的不重要的人更好、更优秀。”这里比较的是down—to—earth persons和别人。故答案为those。

　　37.often 【解析】本句话的意思是“那些自我感觉很了不起、内心充满骄傲的人，总是不需要理由的就被人认为是趾高气扬的人。”故这里答案为often。

　　38.no 【解析】本句话的意思是“那些趾高气扬的人不可能是那些平易近人的人”。这是否定的意思，故答案为no。

　　39.use 【解析】后面的一句话“The expression is‘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。

　　40.with 【解析】根据对等关系，这里应该与后面的部分“a person with a good understanding”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。

　　41.of 【解析】“对现实的了解”的英文表达是“the understanding of reality”，这里的介词用of。故答案为of。

　　42.but 【解析】这里表达的前后句意是一种转折关系。前面说“he may have dreams，”而后面“he does not allow them to block his knowledge...”的意思却是“但是他也不会让这些梦想阻挡自己对什么是现实的理解。”故答案为but。

　　43.what 【解析】解析同上。这里是一个名词性从句，what在句中做主语。故答案为what。

　　44.person 【解析】本句话的意思是“与此相反的一类人是那些想入非非的人。”根据上下文的要求这里应该填入man的同义词。故答案为person。

　　45.whose 【解析】这是一个后置定语从句，用whose来引导，表示mind与dreamer的所属关系。故答案为whose。

　　46.Sometime【解析】通过对后面句子的分析，我们可以知道那些想人非非、飘飘欲仙的人有朝一日也是可以“双脚落地的”，那就是“sharp words from teacher”，所以这里表示的是“有朝一日”，故答案为sometime。
