题目内容
15.I don't think the experiment is ___ failure,because it has provided us with ___valuable experience for our future tests.( )A. | 不填; 不填 | B. | 不填; a | C. | a; a | D. | a; 不填 |
分析 我认为这次实验并不是一个失败的实验;因为它为我们的未来测试提供了宝贵的经验.
解答 答案:D.
本句中的failure表示一次具体的失败的实验,属于抽象名词具体化的用法,所以用不定冠词a来修饰;而后面的experience为一个不可数名词,意为"经验",前面使用零冠词;故选D.
点评 解答冠词的题目注意分清句中所表示的内容是特指还是泛指,表示泛指一般用不定冠词a(an);而表示特指用定冠词the.
