In recent years, plank exercise(平板支撑) has become more and more popular. It's easy to find a proper place to do plank exercise. You can even do it with a chair! But you need to use a stable chair to ensure your safety. Moreover, doing plank exercise regularly may bring you lots of benefits.
Performing plank exercise as a daily home exercise before or after school will not only speed up your metabolism(新陈代谢),but also keep your metabolic rate(速率) high all day long. Doing it regularly will make you burn lots of calories(卡路里). This is especially useful if you have to sit in the classroom for hours every day. A high metabolic rate will help you lose weight and keep in good shape.
Have you ever tried standing on one leg? You couldn't stand straight for more than ten seconds on one leg,right? It's because your muscles aren't strong enough to give you the balance you need. Doing plank exercise regularly will improve your balance. Stronger muscles will also help you stand straight longer.
You will also get some mental benefits. Just think about it:You are sitting all day long. Your muscles get tired,and your legs get heavy. Plank exercise will relax the muscle groups that may cause stress in your body. As a result, it can have a powerful and positive effect on our mood.
Considering all the benefits of plank exercise, will you make it part of your everyday life?

解析
【分析】本题需根据原文中平板支撑后代谢率的变化描述，结合图像特征判断正确选项。先定位原文中代谢率变化的关键信息，明确其变化趋势，再对比四个图像选出匹配项。
【解析】根据原文第二段“Performing plank exercise... will not only speed up your metabolism, but also keep your metabolic rate high all day long”，可知做完平板支撑后，代谢率先上升，之后保持较高且稳定的水平。观察四个图像：A为“先升后降”，B为“先升后降再升”，C为“先降后升”，D为“先升后平稳”，符合代谢率的变化趋势。
【答案】D
【知识点】英语阅读理解、图表信息分析
【点评】本题为跨学科题目，需结合原文信息与图像特征解题，考查信息提取与转化能力，难度中等。
【难度系数】0.6
