On the other hand，he did not accept as well founded the charge made by some of his critics that, while he was a good observer, he had no power of reasoning.
[核心词汇]
well founded 有理由的，有根据的// charge(v./n.) ①(收)费用②控告；指责③命令，指示
[结构分析]
本句的主干结构为he did not accept the charge as well founded（他认为这种指责是毫无依据的）。made by some of his critics（一些评论家做出的）为charge的后置定语，that引导同位语从句，作charge的同位语，同位语从句的主干结构为he had no power of reasoning（他没有推理能力），同位语从句中包含一个while引导的让步状语从句while he was a good observer（虽然他善于观察）。
[翻译技巧]
主干的主语和谓语较容易辨认，但宾语不容易看出。因为宾语带有很长的修饰语，所以宾语和宾语补足语发生了倒装，正常语序应为he did not accept the charge as well founded，翻译时应还原成正常语序，而且本句中发生了否定前置，翻译时需把否定词放在原来的位置，则主干可译为：他认为这种指责是毫无依据的。the charge后跟一个过去分词短语作其定语以及一个that引导的同位语从句，该部分信息量较大，需采用分译法，将较长的修饰语独立翻译成句，这就要用到转换法，将some of his critics 处理成主语，made (the charge)处理成谓语，而同位语从句转换译作宾语从句，则这部分译为：一些评论家指责达尔文虽然善于观察，却没有推理能力。while he was a good observer中，形容词good及名词observer均转译作动词。
