题目内容
7.Today is the boy's _____ birthday.He is 12 years old.( )| A. | twelve | B. | twelveth | C. | twelfth | D. | the twelfth |
分析 今天是那个男孩的12岁生日,他12岁了.
解答 答案:C.
根据句意"今天是那个男孩的12岁生日,他12岁了."和设空处后面的单数名词birthday,可知设空处需要一个序数词作定语修饰birthday.表示第几个生日,twelve的序数词是twelfth,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.故选C.
点评 先根据语境判断句中缺少基数词还是序数词,另外注意序数词的拼写和用法,序数词前面一般加定冠词the,如果序数词前面已经有形容词性物主代词或名词所有格,定冠词the应省略.
