这道题是一个典型的词义辨析题,“The explanation for insensitivity to smell seems to be that brain finds itto keep all smell receptors working all the time ”认为鼻子不敏感的解释表明:大脑发现让所有的气味感知器一直处于工作状态是……的。 四个选项的in-否定前缀一开始就容易让考生心里产生逆反心理,接下来的形近词“ineffective”和“inefficient”,若考生无法区分ineffective或者inefficient两者之间的区别,就很容易出现误选。当然B、D选项并没有太大的干扰,根据语境,首先可以排除B、D项。那么接下来,我们一起来看下A、C两个选项:ineffective 和 inefficient一个强调效果,一个强调效率。大脑发现让所有的气味感知器一直处于工作状态会使气味感知器的效率降低。因此,正确答案为C。
The explanation for insensitivity to smell seems to be that the brain finds it inefficient to keep all smell receptors working all the time but can create new receptors if necessary.
