题目内容
2．The train went through ________ 180-metre-long tunnel（隧道）at ________ high speed．（ ）| A． | a； a | B． | an；/ | C． | an； the | D． | a；/ |
分析 这辆火车高速穿过了这个18米长的隧道．
解答 答案：D．不定冠词a一般放在辅音素开头的单词前面，an一般放元音音素开头的单词前面．根据"________ 180-metre-long tunnel"tunnel前面有复合形容词180-metre-long tunnel，指一个18米长的隧道，所以要根据180的读音来选择不定冠词，180读作"one hundred and eighty"one的音标是[w?n]，是辅音音素开头的单词，所以空格处要用a．另外at high speed是固定搭配，意思是"急速，快速"，综上所述，故选D．
点评 首先要掌握不定冠词的用法，还要掌握一些固定搭配的用法，然后结合具体的题目，就可以确定正确答案．
