9.Mary has ________ e-dictionary.She got it from her uncle.( )| A. | a | B. | an | C. | the | D. | / |
分析 玛丽有一个电子词典.她是从她叔叔那得到的.
解答 答案:B.由句意"她从她的叔叔那得到它",it是单数,可知"玛丽有一个电子词典",表泛指;a和an的意思都是"一个",a用于辅音音素前,an用于元音音素前,辅音元音都是指音素不是字母,单词e-dictionary第一个发音为元音/e/,故选B.an.
点评 牢记a和an的用法口诀:a和an很相像,两种用法不一样;辅音音素a提前,元音音素an优先;代在名前来相伴,a和an看不见(名词前若有形容词性物主代词,就不用a和an).
