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 new receptors if necessary.
这道题目对考生对个别词汇的理解及搭配的考察,例如,许多考生就“trigger the receptors”很是受干扰,“激活受体”是常见的搭配,但“激活”应该是对现已存在的食物而言。“ The explanation for insensitivity to smell seems to be that brain finds it inefficient to keep all smell receptors working all the time but can new receptors if necessary”,“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效率低的。但是,需要时又可以……新的气味感知器。”从搭配而言,A、B选项很明显,不符合要求,而C、D选项则可以从空格后面的new来判断,只有create才符合逻辑。因此,正确答案为D。
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.
