选项 _________(51) A:taller B:better C:superior D:higher
答案 D
解析 前面的内容讲的是,体温要保持一定的稳定性,人的身体才会健康。由此可推断,体温过高或过低都说明人的身体出现了问题。结合选项可知选D。 give off意为“发出,放出(气味、热等)";put off意为“推迟”;show off意为“炫耀”;keep off意为“使……远离”。结合句意应选A。 前面简单提到我们的身体需要热量的时候就能产生热量,我们的身体变得太暖和的时 候就会很快地释放热量。根据上下文可知,这里是一个过渡的句子,意为“让我们看看这是怎 么工作的”。故选A。 结合常识可知,当你感到冷的时候,会起鸡皮疙瘩。因此选D。 make做;eat吃;work工作;jump跳。这里说的是如果你感到很冷,你必须要跳来跳去 来取暖。故选D。 前面提到跳来跳去来取暖,那么接着肌肉就开始工作了。then表示“接着”,符合句意。 结合常识可知,颤抖是不令人愉快的,且后面的句子中有prefer,因此应选B。 put on意为“穿上”,符合句意。 supply with意为“提供……”,为固定搭配,符合句意。 more更多的;enough足够的;many很多little很少。此句意为:更多的身体热量用来蒸 发身体里的水分。因此选A。 weather天气;climate气候;circumstance条件,状况;environment环境。结合句意应 选A。 or否则;so that以便;but但是;and和。结合句意应选B。 本句的意思是:你喜欢少运动是因为你的身体足够的暖和。因此选C。 根据后面讲的夏天和冬天的感受可知,这里应选feel, 结合上下文的意思可知,夏天人们喜欢躺在床上什么也不做,而在冬天人们通过运动 来取暖。由此可知,在冬天人们显得生机勃勃。
