题目内容
12.-Have you seen a book?I left it here.-Is it __________English textbook?Mike picked it up.( )
A. | a | B. | the | C. | 不填 | D. | an |
分析 --你有没有看到一本书?我刚才丢在这里的.
--是不是一本英语课本?麦克拿走了.
解答 答案是D.本题考查不定冠词的用法.textbook 是可数名词单数,前面必须有冠词,由此排除C项;第一次提到,泛指,用不定冠词;本题中泛指"一本英语书",所以用不定冠词,排除B.不定冠词a用在辅音音素开头的单词前面;an用在元音音素开头的单词前面,English是元音音素开头的单词,所以答案选择D.注意,第二句中的English book和第一句中的a book不一定是同一本书,所以不能看成是第二次提及而错用定冠词the.
点评 掌握冠词要关注两大方面:一是积累有关不定冠词、定冠词和零冠词的相关的规则;二是积累特殊的短语.
