难点介绍:
对数词的掌握不少同学建立在基数词、序数词及其转换上,很少有人会想到数词的复数形式,结果造成高考中的失分。
题例分析:
例1:It is rare in ________ that people in ________ fifties are going to university for further education.
A. 90s; the B. the 90s; /
C. 90s; their D. the 90s; their
析:D。 第一空表"在90年代",应用in the 90s短语;第二空表"在他们五十多岁时",应用 in their fifties短语,但不少同学不了解数词的复数形式,结果只能乱选一气。
