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。
