17．Don't be angry with him．He's only ________child．（ ）| A． | a | B． | an | C． | the | D． | / |
分析 不要生他的气，他只有一个孩子．
解答 答案：A．
表达的是只有一个孩子，表示"一"，用不定冠词a/an，boy是以辅音音素/b/开头，故用a，故答案是A．
点评 不定冠词，英语虚词冠词的一种，冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义．英语中的冠词有三种，一种是定冠词（the Definite Article），另一种是不定冠词（the Indefinite Article），还有一种是零冠词（Zero Article）．不定冠词a （an）与数词one 同源，是"一个"的意思．a用于辅音音素前，一般读作e，而an则用于元音音素前，一般读做an．
