答案解析
正确答案:C
解析:
这是一道关于英语冠词用法的题目。我们需要分析第 8 空的语境来确定正确答案。
**1. 语境分析**
句子原文为:“It’s ____8____ opportunity to enjoy a bit of adventure...”
这句话的意思是:“这是一个享受一点冒险……的机会。”
这里的 `opportunity`(机会)是一个可数名词单数形式,且在文中是第一次提到,表示泛指“一个机会”,因此需要使用不定冠词(a 或 an)。
**2. 语音规则判断**
选择 `a` 还是 `an`,取决于其后单词发音的**首个音素**:
* 如果后接单词以**辅音音素**开头,使用 **a**。
* 如果后接单词以**元音音素**开头,使用 **an**。
单词 `opportunity` 的音标通常为 /ˌɒpəˈtjuːnəti/ (英式) 或 /ˌɑːpərˈtuːnəti/ (美式)。无论哪种发音,其第一个音素都是元音 /ɒ/ 或 /ɑː/。
**3. 选项排查**
* **A. a**:用于辅音音素开头的单词前,不符合 `opportunity` 的发音规则。
* **B. /**:零冠词通常用于不可数名词、复数名词泛指或专有名词等,此处 `opportunity` 为单数可数名词且表泛指,不能省略冠词。
* **C. an**:用于元音音素开头的单词前,符合 `opportunity` 的发音规则。
**结论**
因为 `opportunity` 以元音音素开头,所以应选用不定冠词 **an**。
故正确答案为 **C**。
