问题     There have been five extinction waves in the planet’s history—including the Permian extinction 250 million years ago,【C1】______an estimated 70% of all land animals and 96% of all marine creatures vanished. The sample polling of animal populations so far suggests that we may have entered【C2】______will be the planet’s sixth great extinction wave.
    Forests razed can grow back, polluted air and water can be cleaned—but【C3】______is forever. And we’re not talking about losing just a few species. In fact, conservationists quietly【C4】______that we’ve entered an age of triage(治疗类选法), when we might have to decide which species can truly be【C5】______.

【C12】
选项 A、tougher
B、worse
C、further
D、closer
答案C
解析 本题空格处是说一项旨在保护森林免遭砍伐的策略更进了一步。所填词前面提到生态环境保护者与当地人合作，以确保濒危物种的保护与当地人的利益密切相关。因此，这里提到的“保护森林免遭砍伐的策略”与之相比应更有效果。go further意为“进一步地说(做)”，与文意相符。因此C项正确。
