一、单项选择（共20题，每题2分共40分）
1. Liu Xiang was chosen for the Chinese team at ________ Athens Olympic Games and won ________ gold medal.
A. a; the B. the. a C. the; 不填 D. 不填; the
【答案】B
【解析】
【详解】本题考查：冠词用法。选项分析：the定冠词，表示特指的人或物。a和an表示泛指的人或物，用于可数名词前。a是不定冠词，用在以辅音音素开头，或以读做辅音音素开头的单词前面。an也是不定冠词，用在以元音音素开头的单词前面，或以读做元音音素开头的单词前面。综合分析前后句， 可知此处填 the. a最合适，前一句特指 Athens Olympic Games ，后一句泛指gold medal一枚金牌。完整句意为：Liu Xiang was chosen for the Chinese team at the Athens Olympic Games and won a gold medal.刘翔在雅典奥运会上被选入中国队，并获得了一枚金牌。正确答案为：B
【点睛】the定冠词，表示特指的人或物。a和an是不定冠词，表示泛指的人或物，用于可数名词前。但a和an又有区别用法：（1）a用在以辅音音素开头的单词前面，例如：a man一个男人。（2）an用在以元音音素开头的单词前面，简言之即an用在元音前，a用在辅音前。一般而言，元音字母发元音，辅音字母发辅音，但也有例外情况，主要有如下例外情况：
(1) 拼写以辅音字母开头读音却以元音开头的单词。例如：hour, honest, honor等单词的拼写虽然以辅音字母h开头，但其读音却以元音开头，因此，前面要用an。
(2) 拼写以元音字母开头读音却以辅音开头的单词。useful, university, usual等单词的拼写虽然以元音字母开头，但其读音却以辅音开头，因此，前面要用a。
