题目内容
12.______ teacher of my grandfather's will come tomorrow.I'm wondering how old ____ man heshould be.( )
A. | The; a | B. | A; a | C. | A; the | D. | The; the |
分析 我爷爷的一位老师每天来.我想知道他应该有多大了.
解答 答案:B句中teacher表示泛指,要用不定冠词来限定,意思是我爷爷的老师中的某一位;第二个空man作系动词的表语,也是表示抽象的泛指,意思是他是多大的一个人.故选B.
点评 冠词是一种虚词,本身不能独立使用,只能放在名词前帮助说明名词所指的人或事物,它是英语词性中最小的一类,只有三个,一种是不定冠词a,an;一种是定冠词the.此外也有些特定场合不用冠词,即通常所称的零冠词.不定冠词表示泛指,定冠词表示特指.
