话题七　饮食与健康(B) A [2019·辽宁五校模拟] “We all know that exercise is good for us, but can you get the benefits without actually doing the exercise？” asks Michael Mosley. Having a hot bath or a sauna is a good way to soothe your arms and legs after exercise, but what happens if you do it instead of exercise? Dr. Steve Faulkner of Loughborough University asked me to take part in an experiment comparing the relative benefits of having a long, hot bath versus an hour of hard cycling. For this study I join a group of volunteers who have all been fitted with monitors which continuously record blood sugar levels. Keeping your blood sugar level within the normal range is an important measure of your “metabolic” fitness. The first part of the experiment is very relaxing, consisting of having a long, hot bath. While I sit in the bath, which they keep at 40 ℃， Steve closely monitors my core temperature. Once it has risen and stayed there, I am allowed out. A couple of hours after my bath I have a light meal. Since we want to see how having a hot bath compares with exercise we repeat the experiment. So what's the result? “One of the first things that we were looking at，” Steve says, “is the energy expenditure (消耗) while you're in the hot bath and what we found was an 80% increase in energy expenditure just as a result of sitting in the bath for the course of an hour.” This is nothing like as many calories as cycling for an hour (which comes out at an average of 630 calories), but we do burn 140 calories, the equivalent of a brisk 30­minute walk. 体裁：说明文　题材：健康　主题：洗热水澡的好处 【文章大意】　实验发现，一个小时的热水浴虽然没有骑一个小时自行车所消耗的热量多，但其所消耗的热量相当于半个小时的快步走所消耗的热量。 【难句分析】　“One of the first things that we were looking at，”Steve says，“is the energy expenditure (消耗) while you're in the hot bath and what we found was an 80% increase in energy expenditure just as a result of sitting in the bath for the course of an hour.” 分析：本句是直接引语，直接引语中是一个并列句。该直接引语中and连接并列句；that引导定语从句；while引导时间状语从句；what引导主语从句。 译文：“我们一直研究的第一类事情之一就是你在洗热水
