instead, wait at least 30 minutes after a typical routine, or as much as an hour after a hard workout. Remember to drink throughout exercise to make up for㉜ water lost㉝ to sweat. 该句是复合句。like cars that run on petrol使用了类比的写作方法，that引导定语从句。 该句是简单句。to help your muscles recover and repair themselves after exercise作目的状语。 该句是简单句。when to eat作主语，是“疑问词＋to do”结构； is also of great importance是“be＋of＋抽象名词”结构。 该句是并列句。两个分句都使用了祈使句。 ㉕petrol/'petrəl/n.汽油 ㉖energy/'enədʒi/n.能，能量；精力；能源 ㉗plenty of 大量；很多 ㉘keep up保持 ㉙be rich in含有丰富的……；富于 ㉚in general通常；大体上；一般来说 ㉛average/'ævərIdʒ/n.平均水平，一般水准adj.平均的；典型的 ㉜make up for弥补，补偿 ㉝lost adj.迷途的，丢失的 be lost in全神贯注于 Lost and Found失物招领处 正确的饮食 就像汽油驱动的汽车一样，你的身体消耗碳水化合物来提供能量。像面条、大米、水果和蔬菜这样的食物都含有碳水化合物，可以在长时间的锻炼中保持能量。为了帮助你的肌肉在运动后恢复和修复，你需要吃富含蛋白质的食物，如鱼、鸡蛋和奶制品。什么时候吃也很重要。一般来说，你应该在运动之前的平均1.5到2.5小时内吃饭。运动后不要立即进食；相反，在常规锻炼后至少等30分钟，或者在高强度锻炼后等一个小时。记住运动时全程都要喝水，以弥补流汗所造成的水分流失。 Avoiding injury To prevent㉞ soft tissue injury㉟， make sure㊱ that you wear proper clothes and equipment㊲ when exercising. You should also start small and slowly work your way to a longer and harder exercise routine to avoid㊳ getting hurt.Finally, remember to warm up before exercising and stretch at the end of your workout. ㉞prevent/prI'vent/vt.阻止，阻碍 ㉟injury/'Indʒəri/n.伤害，损伤 ㊱make sure 弄清；设法保证，确保 ㊲equipment/I'kwIpmənt/n.配备，装备；设备 ㊳avoid vt.避免，回避 avoid doing sth.避免做某事 避免受伤 为了防止软组织受伤，运动时一定要配备合适的衣服和器材。你也应该从小处开始，慢慢地进行长时间、高强度的锻炼，以避免受伤。最后，记住在开始运动前要热身，在运动结束时要拉伸。 So, now you know the benefits of exercise and how to do it safely and effectively. What are you waiting for? 该句是复合句。that引导宾语从句，其中when exercising是状语从句的省略形式，补全应为：when you are exercising。 该句是简单句。and连接两个并列宾语，其中how to do it safely and effectively是“疑问词＋to do”结构，作know的宾语。 所以，现在你知道了运动的好处以及如何安全有效地运动。你还在等什么？ Part 2　语篇研析 Ⅰ.Fill in the blanks with suitable words.

Exercise has positive effects on the brain's functions.Exercise decreases anxiety, which is the body's natural response to stress.Norepinephrine (去甲肾上腺素), which involves levels of stress, can be moderated with exercise because exercise increases the amounts of it. Exercise enhances brain health.The brain is the center of control for the body's entire sense of functioning, and without it all that would be left is muscles and bones.The mental health is linked to exercise.Mental health can be strengthened by physical activity whether it is a casual walk in the park, or intense weight lifting training.Exercise promotes positive body images when increasing self-esteem, and helps increase the overall self image.The emotional and mental benefits from exercise are vital and only growing, as more is being discovered about the brain's functions. Exercise is complex, and constantly changing.The physical benefits of flexibility, muscular strength and muscular endurance are all vital to creating a healthy body.The health benefits from exercise range from heart to immune system, and more are being discovered every day to help increase one's life.Exercise is not limited to just the gym, but an entire existence.The combination of benefits is what makes exercise so cardinal.Exercise is one of the most important activities someone can introduce into their lives.A walk around a neighbourhood, or training for a team, any effort towards getting your heart rate going makes a difference.Exercise is universal and beneficial to everyone.

Take a walk around the neighborhood.” Comments like this are often said with nothing but the best of intentions, but they used to make me angry as much as being told to drink more water.I did not understand how these things were going to help. Three years ago, I hit a low point.Once I saw a pair of empty eyes looking at me through the mirror, I knew I was at my breaking point.So, I took the advice I fought so hard to ignore.I went for a walk—with the hope that it would somehow change my life. I embraced (拥抱) the fresh air everyone seemed to be talking about.But it did nothing.I was just as sad as I was before.I went on a walk every single day for more than a month.Some days I could hardly make it outside, but I managed to push through.I took a picture every time I went.I think I wanted to document myself trying to make an effort.One day, the unthinkable happened.I found myself smiling.I realized I had patiently waited all morning to go on this walk.What I once hated had become the best part of my day.I found myself longing to be outside.I never had a destination in mind.I just danced along the trails (小路), stopped to look at the beautiful blue skies and listened to music. I'm glad I took pictures because there was a noticeable difference in my face.I slowly started to look less tired and defeated.I don't know why I refused to go on that walk for so long.I guess I didn't want to believe that something small and seemingly meaningless could actually make an impact on my physical and mental well-being. If you're having a bad day, a bad month, a bad year or even a bad life, you should try going for a walk.Sometimes, all we need to do is try. [语篇解读]　本文是一篇夹叙夹议文，主要讲的是作者原本觉得别人介绍的在烦恼的时候去散步的建议是无用的，在有一次作者处于人生低谷的时候，作者尝试去散步，坚持下去后作者看到了自己的变化。所以，作者建议读者过得很糟糕的时候去尝试散步。 5 6 7 8 5．How did the author use to feel when people suggested she go for a walk?

A．Go for a walk when feeling down. B．Care about our mental well-being. C．Stay positive when bad things happen. D．Take other people's suggestions seriously. 答案：A 5 6 7 8 细节理解题。根据最后一段中的“If you're having...going for a walk.(如果你有糟糕的一天，糟糕的一个月，糟糕的一年，甚至糟糕的生活，你应该试着去散步)”可知，作者建议我们情绪低落的时候出去散散步。故选A。 5 6 7 8 C Spending time outdoors has long been linked to better health.Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental health. Gardening involves physical activity that works all the main muscle(肌肉) groups, which is helpful for overall health.“Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength，” said Clayton, CEO of an online lawn care company.“Performing these activities regularly can help burn calories, and keep a healthy weight.” Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统).The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity.Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease.Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth. Gardening provides a chance for social connection, too.It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging. Gardening also offers cognitive (认知的) benefits.It excites the senses, improves focus and encourages problem-solving and creativity.It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature. [语篇解读]　本文是一篇说明文。文章主要讲述了园艺活动有利于身体健康并分析了原因。 9．What is Clayton's attitude towards gardening? A．Supportive. B．Doubtful. C．Unclear. D．Uncaring. 答案：A 9 10 11 12 观点态度题。根据第二段中的“Activities such as digging...keep a healthy weight.”可知，Clayton对园艺活动持支持的态度。故选A。 9 10 11 12 10．What does paragraph 3 mainly tell us about gardening? A．It improves focus. B．It is a waste of time. C．It can keep a body in shape. D．It helps to reduce the risk of diseases. 答案：D 9 10 11 12 段落大意题。第三段主要讲园艺活动有助于降低患病的风险。故选D。 9 10 11 12 11．How does gardening affect social connection according to the text? A．It contributes to creativity. B．It encourages problem-solving. C．It builds relationships between people. D．It improves people's awareness of safety. 答案：C 9 10 11 12 细节理解题。根据第四段的内容可知，园艺活动对社交的影响是它可以建立人们之间的关系。故选C。 9 10 11 12 12．What is the best title for the text? A．How to Start a Garden B．Choose a Garden or Not C．What Plants Grow Best in a Garden D．Start Gardening and Get the Health Benefits 答案：D 9 10 11 12 标题归纳题。文章主要讲述了进行园艺活动有利于身心健康，所以D项“开始园艺并获得健康益处”最适合作为文章的标题。故选D。 9 10 11 12 Ⅱ.阅读七选五 [语篇解读]　本文是一篇说明文。哈佛医学院教授Peggy Cawthon给我们指出了四点有关走路锻炼的建议。 1 2 3 4 Walking might seem simple.“But it's not，” explains Peggy Cawthon, a professor at Harvard Medical School.“It's an amazingly complex behavior when we try to understand how to improve our lives as we age.” 1 ？ Here are a few ideas. 5 1 2 3 4 A．Start planning now B．Be in pretty good shape C．You need to improve your skill D．So what steps should we take to do it right E．How can you sweat your way to good health F．It is a helpful reminder that our bodies need action G．Basically, the body part controlling everything is your brain 答案：D 5 根据空后的问号可知，这里是一个问句。根据上文“It's an amazingly complex behavior when we try to understand how to improve our lives as we age.(当我们试图了解如何随着年龄的增长而改善我们的生活时，这是一种令人惊讶的复杂行为)”和下文“Here are a few ideas.(以下是一些想法)”可知，空处应是询问应该如何做，D项符合语境。 1 2 3 4 5 Don't stop exercising Cawthon agrees that the worst thing a person can do is to stop exercising.“You'll feel the effects almost immediately，” says Cawthon.Sitting for hours leaves her uncomfortable, and it's the days when she types that her arthritis (关节炎) doesn't cause much pain. 2 ． 1 2 3 4 5 A．Start planning now B．Be in pretty good shape C．You need to improve your skill D．So what steps should we take to do it right E．How can you sweat your way to good health F．It is a helpful reminder that our bodies need action G．Basically, the body part controlling everything is your brain 答案：F 1 2 3 4 5 根据本段的小标题“Don't stop exercising”和上文“Sitting for hours...doesn't cause much pain.”可知，本段主要讲述的是不要停止锻炼，并指出久坐不动会不舒服，而用打字来活动手指可以让关节炎有所减轻。由此可知，空处承接上文，应是说这提醒了我们需要运动，F项符合语境。 1 2 3 4 5 Train yourself to walk with skill To truly improve your walking, you need to think like an athlete.Imagine you want to play tennis, but you have a bad backhand.Playing lots of tennis won't fix the problem, Cawthon says. 3 ．It's the same thing with walking. 1 2 3 4 5 A．Start planning now B．Be in pretty good shape C．You need to improve your skill D．So what steps should we take to do it right E．How can you sweat your way to good health F．It is a helpful reminder that our bodies need action G．Basically, the body part controlling everything is your brain 答案：C 1 2 3 4 5 根据本段小标题“Train yourself to walk with skill”可知，关键词是“skill”。上文“Imagine you want...the problem, Cawthon says.”讲述了打网球时不能靠多打网球来解决自己的反手问题，所以空处应是说要提高技能，C项符合语境。故选C。 1 2 3 4 5 Give your brain a boost (激励) 4 ．So don't forget that when working out your fitness plan.Cawthon has been studying an area of the brain related to motivation (动机) and executive function.Subjects with a boost walk more steps on average than the control group, and they have been maintaining that even several months later. 1 2 3 4 5 A．Start planning now B．Be in pretty good shape C．You need to improve your skill D．So what steps should we take to do it right E．How can you sweat your way to good health F．It is a helpful reminder that our bodies need action G．Basically, the body part controlling everything is your brain 答案：G 1 2 3 4 5 根据本段小标题“Give your brain a boost”可知，关键词是“brain”和“boost”。再结合下文中的“Cawthon has been...and executive function.”可知，大脑控制一切，G项符合语境。故选G。 1 2 3 4 5 5 So when should we face the music about our mobility? There is no final answer for when walking problems begin to come up.“You should be as active as you can at any age，” Cawthon says, noting that people who are healthy in their 20s and 30s are best equipped to deal with future age-related challenges.“The best time to start is now.Next best is tomorrow，” she says. 1 2 3 4 5 A．Start planning now B．Be in pretty good shape C．You need to improve your skill D．So what steps should we take to do it right E．How can you sweat your way to good health F．It is a helpful reminder that our bodies need action G．Basically, the body part controlling everything is your brain 答案：A 1 2 3 4 5 空处是本段小标题，根据上文小标题的形式可知，这里应用祈使句。根据下文中的“The best time to start is now.Next best is tomorrow”可知，本段建议要从现在开始，A项“立即开始计划”符合语境。故选A。 1 2 3 4 5 $$
