A、even
B、far
C、more
D、less
【正确答案】：C
【题目解析】：在第35题中，句子提到“这些物种对环境变化的适应能力降低，事实上，它们变得更加濒危。” 这里的关键词是“变得更加濒危”，表明与前文提到的某种情况相比，现在的濒危程度是增加了的。 选项A "even" 通常用于强调某个情况或程度，但在这里并不适用，因为句子没有提供与之比较的先行词或背景信息。 选项B "far" 意味着“远远地”或“在很大程度上”，但它通常用于描述距离或程度，而不是用于比较。 选项C "more" 适用于比较句，表示“更多”或“更加”。在这个上下文中，“more endangered” 是与前文提到的某个情况相比较而言的，意味着这些物种现在比之前更加濒危。 选项D "less" 意为“更少”，这与句子中“变得更加濒危”的意思相反，因此不是正确的选择。 综合上述分析，我们可以确定答案是C，“more”。这是因为它符合句子中比较结构的要求，表达了物种濒危程度增加的意思。
