一、选择题
1．B
解析：B
【详解】
句意：泰国是一个亚洲国家，它是一个可以参观的好地方。
考查冠词。a一个，修饰辅音音素开头的单数名词；an一个，修饰元音音素开头的单数名词；the那个，表示特指；D项是零冠词。Asian是元音音素开头，因此用不定冠词an修饰，故选B。
2．C
解析：C
【解析】
【详解】
句意：——听着，弹吉他的年轻女子是一位大学教师。——她的表演相当不错。
考查冠词。演奏某种乐器的乐器前用定冠词the，可知“弹吉他”是paly the guitar；不定冠词（a、an）表示泛指、类指，仅用在单数可数名词前来表示"一"的意义，但不强调数目概念，只表示名词为不特定者，a用于辅音音素开头的可数名词单数前，an用于元音音素开头的可数名词单数前，第2个空格填不定冠词表示泛指，“一位大学教师”，university [ˌjuːnɪˈvɜːsəti]辅音音素开头，可知填a；故选C。
【点睛】
冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种：定冠词、不定冠词、零冠词。
（一）不定冠词a(an)与数词one同源，是"一个"的意思，用在可数名词单数前，a用于辅音音素开头的可数名词单数前， an则用于元音音素开头的可数名词单数前。不定冠词可表示泛指，指某类事物中的一个，意思是“一个/只…”，也用于一些固定词组中。例如，He is a teacher.( 某类事物中的一个) an hour（一个…）have a rest（固定词组）。
（二）定冠词的用法：（1）特指某（些）人或某（些）事物。（2）指双方都知道的人或事物,例如：Open the door, please. （3）指上文提到的人或事物。（4）用在世界上独一无二的事物前。例如：The sun is bigger than the moon.太阳比月亮大些。（5）用在序数词和形容词最高级前。例如：The first island is the biggest of the three.第一个小岛是三个中最大的。（6）乐器前用定冠词the，例如，play the guitar：弹吉他。（7）用在形容词前表示一类人，the +形容词指的是一群人，是一种复数含义，所以其后动词应用复数形式。例如：The old are sick.（8）用于一些固定短语中，如the Great Wall：长城；the United States of America：美国。
（三）零冠词的用法 ，就是不用冠词的情况。1) 国名，人名前通常不用定冠词：England, Mary。2) 不可数名词和复数名词表示泛指时，表示一类人或事物时，可不用冠词；They are teachers. 他们是教师。Failure is the mother of success. 失败乃成功之母。3) 在季节、月份、节日、假日、日期、星期等表示时间的名词之前，不加冠词；We go to school from Monday to Friday. 我们从星期一到星期五都上课。4) 在三餐、球类运动和娱乐运动的名称前，不加冠词；如：have breakfast, play chess。5) 当by与火车等交通工具连用，表示一种方式时，中间无冠词；by bus, by train；6) 固定短语，如：go to hospital去医院看病；at home, in class, go to bed等。
3．B
解析：B
【解析】
【详解】
句意：——看！她是好莱坞最著名的女演员之一。——是的，她当然是很有名气，但是我认为她穿的这条裙子很难看。第一个空，one of the+形容词最高级，属于固定搭配，表示“最…之一”；第二个空，根据句意可知此处表示的是泛指，而且ugly是以元音发音开头的单词，所以用不定冠词an。故答案选B。
4．D
解析：D
【详解】
本题考查：冠词用法。选项分析：a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用在以元音音素开头的单词前面。序数词前加不定冠词表示“再......，又......”之意；加定冠词表示顺序。此处表示再，又之意，不表示顺序，故应该用不定冠词。综合分析前后文及答案选项，second以辅音音素开头，选a最合题意。完整句意为：I didn't do my best . Could you give me a second chance, please我没有尽力。你能再给我一次机会吗？正确答案为：D
【点睛】
a和an都用来修饰可数名词的单数。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。
