题目内容
10．-What were you doing at about eight last night？-I was at ______ home reading book．（ ）
| A． | a，a | B． | 不填，不填 | C． | 不填，a | D． | the，a |
分析 --你昨晚大约八点时在做什么？--我在家读书．
解答 答案：C．home是副词前面不加冠词，故第一空不填；在读一本书，这本书也是不确定的，故用a/an，而book[buk]的第一个音素是辅音音素，所以用a 故选C
点评 本题考查冠词的用法，冠词分为定冠词、不定冠词及零冠词．定冠词the表特指或是双方都知道的人或物，不定冠词an用在元音音素的前面，a用于辅音音素的前面．另外，也应该知道home是副词，前面是不用冠词的．
