题目内容
4.-How far is it from your home to the school?-Half _______ hour's walk.( )| A. | a | B. | an | C. | the |
分析 --从你家到学校有多远?--步行半小时.
解答 答案:B.half an hour是固定短语,译为"半小时",另外,a 和an 均用在单数名词之前,an 用在以元音音素开头的单词前,hour,honest,honor等单词的拼写虽然以辅音字母h开头,但其读音却以元音音素开头,因此,前面要用an.故选B.
点评 本题考察固定短语half an hour,并知道an 用在以元音音素开头的单词前,熟知可做出正确选择.
