问题
选择题
John had made up his mind to give it up, but on _________ second thought he determined to have __________ third try.
A．/ ; /
B． a; a
C．the; a
D．/ ; a
答案
答案：D
题目分析：thought是抽象的名词，抽象的名词前不用冠词，故第一个空什么都不填；第二个空表示泛指，故用不定冠词a。
点评：解答有关冠词的题型首先必须要把题目完完整整看清楚，理解句子意思，然后可以从三方面入手，一是习惯搭配，二是固定短语，三是具体语境分析。对于固定短语平时应多读多记。
