题目内容
Not everyone has realized what_______ important part the balance of________ nature plays in their life.
| A．an；the | B．/；the | C．an；/ | D．the；/ |
C
解析试题分析：考查冠词及短语的用法。第二空nature“自然”时前面不需用冠词，类似的还有space“太空”；man“人类”。第一空是play an important part in their life短语，用了what引导的感叹句，正常语序应是the balance of nature plays an important part in their life，被感叹的是名词part所以用what来引导，故选C。
