题目内容
18．I want to give a special present for our motherland'sixtieth （sixty） birthday．分析 我想为祖国的六十岁生日献上一份特殊的礼物．
解答 答案：sixtieth
根据句意"我想为祖国的六十岁生日献上一份特殊的礼物"和设空处后面的单数名词birthday，可知设空处的六十需要用序数词作定语修饰birthday，表示第六十个生日．sixty的序数词是sixtieth，故答案为：sixtieth
点评 本题主要考查数词的使用．基数词强调数量，后面常跟名词复数，序数词强调顺序，常与the搭配，特指某一个，但名词前已有物主代词或名词所有格时，定冠词the要省略．
