To see how exercise impacts fat tissue，researchers compared fat tissue just under the skin from two groups of 16 people with overweight problem：those who reported exercising at least four times a week for at least 2 years，and those who did not exercise regularly.People who had a history of regular exercise in the past had fat cells with features that allowed them to store more fat. Results from the former group showed several structural changes in fat tissue，including slightly smaller fat cells and more of them，and changes in proteins that adjust body fat remodeling.However，many of the above changes disappeared when regular exercise stopped.Dr.Horowitz，professor of movement studies at the University of Michigan，said，“This is one of the big reasons why it is so important to be physically active most days.Exercise can help you to keep going longer or push harder in your work.” The key takeaway of the study is that we’re broadening our understanding of why it is helpful to exercise.There are so many ways to exercise，and figuring out a way to make it part of the daily routine plays an important role.Of course，you should check with your doctor first to make sure it’s safe. 1.What can we learn about fat tissue from paragraph 1? A.It is most energy-demanding. B.It has little to do with fatness. C.Its location makes a difference. D.Its function is to control health. 细节理解题。根据第一段中“Fat tissue is supposed to be stored under the skin.If it can’t go there，it’s going to other places such as your liver，heart or pancreas(胰腺).More fat in those organs could affect how well they function.”可知，脂肪组织的位置很重要，若不在皮肤下而在其他器官，则会影响器官功能。故选C。 解析 √ 2.How are the participants in the research grouped? A.By their health problem. B.By their body weight. C.By their workout habit. D.By their personal hobby. √ 细节理解题。根据第二段中“To see how exercise impacts fat tissue，researchers compared fat tissue just under the skin from two groups of 16 people with overweight problem：those who reported exercising at least four times a week for at least 2 years，and those who did not exercise regularly.”可知，研究参与者按照锻炼习惯进行分组。故选C。 解析 3.What is stressed in paragraph 3? A.Weight loss depends on less fat tissue. B.Exercise can reshape protein structure. C.Harder training results in stronger fat tissue. D.Fat tissue is sensitive to exercise frequency. 段落大意题。根据第三段中“Results from the former group showed several structural changes in fat tissue...However，many of the above changes disappeared when regular exercise stopped.”可知，第三段强调的是脂肪组织对运动频率很敏感。故选D。 解析 √ 4.What is the purpose of the last paragraph? A.To raise a proposal. B.To present evidence. C.To prove the finding. D.To advance the study. 写作意图题。根据最后一段中“There are so many ways to exercise，and figuring out a way to make it part of the daily routine plays an important role.Of course，you should check with your doctor first to make sure it’s safe.”可知，最后一段的目的是提出建议，让人们找到一种将锻炼融入日常生活的方法。故选A。 解析 √ B(此篇精读) (2025·山东淄博高一上期末) Lately I have started to go jogging in Yoyogi Park.One of the first things that caught my attention when I started was that everybody runs in a counterclockwise(逆时针方向的) direction in the city where there were no rules that said in which direction to run. 语篇解读　这是一篇说明文。文章主要讲述了作者在代代木公园慢跑时注意到人们总是逆时针方向跑步的现象，并通过询问和网上研究找到了东京早稻田大学一位建筑教授的研究作为最佳答案，解释了人们倾向于逆时针方向跑步的原因。 Maybe they do it because they try to imitate track & field athletics and almost any other kind of race where the running direction is always counterclockwise，or maybe is there any other reason? I have been asking many people and “researching” online.The best answers I found are from the research of a construction professor at Waseda University in Tokyo. Professor Hitoshi Watanabe contributed many years of his life to research about which is the best way to design stairs and emergency exits.He reached a point in his research where he had to decide if it was better to design stairs that you have to go down clockwise(顺时针方向地) or counterclockwise.Experiments had been carried out before，and it was known that there is a tendency to turn counterclockwise.But Mr Watanabe wanted to look into more： ·Most human beings are right-handed. ·Most of the left-handed people are right-footed，while most of the right-handed people are also right-footed. ·Most human beings have a slightly longer right leg than their left leg. These three factors make our right leg become dominant over the left leg，which causes a tendency to turn to the left，and to be able to run faster in a counterclockwise direction. Mr Watanabe carried out a lot of experiments and observations to reach some results.For example，he found out through an experiment that when people are being run after and trying to escape，they turn to the left unawarely 70% of the time. 5.What caught the author’s attention when he first started jogging in Yoyogi Park? A.The experiment in the physics of running. B.The direction everyone was running in. C.The specific running rules in the park. D.The research about track & field athletics. √ 细节理解题。根据第一段中的“One of the first things that caught my attention when I started was that everybody runs in a counterclockwise(逆时针方向的) direction in the city where there were no rules that said in which direction to run.”可知，作者刚开始在代代木公园慢跑时，注意到的是每个人跑步的方向。故选B项。 解析 6.What led Mr Watanabe to further look into people’s tendency to turn left? A.His doubts about the best running style. B.His curiosity about human behavior tendencies. C.His observation of the way people go downstairs. D.His need to determine the ideal direction for stairs. √ 细节理解题。根据第三段中的“Professor Hitoshi Watanabe contributed many years of his life to research about which is the best way to design stairs and emergency exits.He reached a point in his research where he had to decide if it was better to design stairs that you have to go down clockwise(顺时针方向地) or counterclockwise.”可知，他需要确定楼梯的理想方向这一件事促使他进一步研究人们向左转的运动倾向。故选D项。 解析 7.What does the underlined word “dominant” mean in the passage? A.Stronger. B.Opposite. C.Weaker. D.Equal. 词义猜测题。根据第三段中的“Most human beings are right-handed.Most of the left-handed people are right-footed，while most of the right-handed people are also right-footed.Most human beings have a slightly longer right leg than their left leg.”可知，大多数人惯用右手和右脚，右腿也比左腿稍长，所以右腿比左腿更强壮，故画线词dominant意思是“更强壮的”，和stronger的意思相近。故选A项。 解析 √ 8.What is the best title for this passage? A.The Right Way to Design Stairs B.Research on Yoyogi Park Jogging C.The Science Behind Running Direction D.The Benefits of Running Counterclockwise 标题归纳题。通读全文可知，文章主要讲述了作者在代代木公园慢跑时注意到人们总是逆时针方向跑步的现象，并通过询问和网上研究找到了最佳答案，解释了人们倾向于逆时针方向跑步的原因。C项“跑步方向背后的科学”为本文最佳标题。故选C项。 解析 √ 1.catch one’s attention引起某人的注意 2.in a(n)...direction在某个方向上；朝……方向 3.carry out实施；执行 4.there is a tendency to倾向于做某事 5.observe vt.遵守；注意到；观察；庆祝→observation n.观察；观测；监视→observer n.观察者；观测者 6.run after追赶；追逐 7.determine vt.确定；支配；决心 vi.决心 词汇积累 1.One of the first things that caught my attention when I started was that everybody runs in a counterclockwise direction in the city where there were no rules that said in which direction to run. 分析：此句为复合句。主句为One of the first things was...；第一个that引导的是定语从句，第二个that引导的是表语从句；第三个that引导的是定语从句；when引导的是时间状语从句；where引导的是定语从句。 翻译：当我开始慢跑时，首先引起我注意的事情之一是，在这个没有规定跑步方向的城市里，每个人都朝着逆时针方向跑步。 句式分析 2.He reached a point in his research where he had to decide if it was better to design stairs that you have to go down clockwise or counterclockwise. 分析：此句为复合句。point为先行词，表示抽象地点，后面跟有where引导的定语从句；if引导宾语从句，意为“是否”；that引导定语从句，修饰前面的stairs。 翻译：在他的研究中，他到了一个必须决定是设计顺时针下楼还是逆时针下楼的楼梯更好的阶段。 (2025·江苏泰州高一上期末) Most people connect running with speed.It is often regarded as an exercise that leaves runners breathless and tired when they finish. 语篇解读　本文是一篇说明文，主要介绍了慢跑这一运动方式。 Ⅳ.七选五阅读 A.The idea of “slow” can differ greatly between persons. B.However，different running styles have different benefits. C.It also helps in burning fat more efficiently in your body. D.For most people，this speed is just slightly faster than walking. E.Recovery from slow jogging can last from several days to weeks. F.Despite its slow speed，keeping proper body’s position is important. G.Running at a slow speed might give the impression that time passes more slowly. On the other hand，when someone runs slowly，they might feel like they are not putting in enough effort. 1 Slow jogging，a leisurely form of running，can be a beneficial addition to your running routine. √ 上文“It is often regarded as an exercise that leaves runners breathless and tired when they finish.On the other hand，when someone runs slowly，they might feel like they are not putting in enough effort.”讲述了慢跑和人们认为的常规跑步方式的不同，下文“Slow jogging，a leisurely form of running，can be a beneficial addition to your running routine.”讲述了慢跑这种跑步方式可以成为你日常跑步的有益补充。B项“然而，不同的跑步方式有不同的好处”呼应上文的两种跑步方式，引出下文慢跑的好处，符合题意。故选B。 解析 2 For a competitive marathon runner，a slow speed will be very different from that of someone who only goes on quick daily jogs around their neighborhood.

E.Recovery from slow jogging can last from several days to weeks. F.Despite its slow speed，keeping proper body’s position is important. G.Running at a slow speed might give the impression that time passes more slowly. √ 上文“If you measure your speed for a five-kilometer race，slow jogging will usually be around two minutes slower per kilometer.”讲述了慢跑的速度比五公里跑步比赛的速度慢，D项“对于大多数人来说，这个速度只是比走路快一点”承接上文，符合题意。故选D。 解析 There are some tips for you to start your slow jogging. 4 This includes taking shorter，quicker steps—about 180 per minute—and landing on the mid-foot rather than the heel. A.The idea of “slow” can differ greatly between persons. B.However，different running styles have different benefits. C.It also helps in burning fat more efficiently in your body. D.For most people，this speed is just slightly faster than walking. E.Recovery from slow jogging can last from several days to weeks.

Running is an activity that can be hard on muscles and bones，especially if you keep a consistent speed for a long period.Slowing your speed helps prevent injuries by spreading stress to different areas of your body and reducing the effect on joints.Moreover，slow jogging is a good exercise to strengthen the heart and lungs. 5 Perhaps most importantly，jogging at a slower speed allows you to enjoy run more.If you are interested in getting any of these benefits，it’s certainly worth giving slow running a try. A.The idea of “slow” can differ greatly between persons. B.However，different running styles have different benefits. C.It also helps in burning fat more efficiently in your body.
