When the president and his delegation left the country, _____of people were at the airport to _____.


A、thousand; see off them
B、thousands; see off them
C、thousand; see them off
D、thousands; see them off
【正确答案】：D
【题目解析】：本题考查数词的用法和固定搭配。句意：当总统和他的代表团离开国家时，成千上万的人们在机场为他们送行。hundred, thousand, million等在构成“具体的数字”时不用复数形式；只有在表“概数”时才用复数形式。一般的搭配都是hundreds/ thousands/ millions of＋名词的复数。see sb. off意为“为……送行”，当sb.为代词时，放在see和off中间。
