对这提议点头绪都没有 我知CD是错的 但是我不懂A与B 可否帮我解释一下

像是A understanding是做名词还是形容词啊 若是名词 会何可以直接接名词呢 若是形容词 不是应该放在role 前面 the的后面吗 我真的不清楚 请救救我

28. Paleoanthropologists examine fossil remains of extinct primates, while physical anthropologists concern with ethnology study the behavior of primates in their natural settings.

答案： B

分析：改为concerning, 在逗号后面的部分，while作连词，后面应该是个完整句子，study作谓语, concerned分词作后置定语修饰主语physical anthropologists

想知道说concern 到底是改 concerning or concerned 再问一个就是 concern 后倒底可不可以加with

原句当是：A challenging new area in inorganic chemistry is （the area of understanding) the role of transition metals in the biochemical catalysts called enzymes. Ａ项中用that，当是同位语结构说明前面的new area，因此that of understanding就好解释了。这里的understanding用-ing是因为它的前面是介词of

concerning with ethnology是修饰anthropologists的,study才是后一个句子的谓语
