Section Ⅳ　 Reading for Writing，Assessing Your Progress & Video Time GOING POSITIVE I always wanted to look like the slim girls on TV even though I knew that it was impossible.　I worried about my weight and tried every new diet I read about online.I tried nofat，lowfat,5∶2，only bananas，no bananas－I almost went bananas，too.  本句是主从复合句。even though引导让步状语从句，且从句中含有that引导的宾语从句。 Then I read an article that said instead of asking “Am I fat？”I should be asking“Am I fit？”I had no idea a letter could make such a difference！Once I started thinking about fitness rather than weight，things began to change.　 Instead of saying“I want to lose three kilos”，I would say“I want to run two kilometres in eight minutes”or“I would to be able to do 30 pushups”．Rather than cutting out the foods I enjoyed，I added healthy foods to my meals.I could still have a burger now and then，but I would add a salad or an apple.  本句是主从复合句，once引导时间状语从句。 Finally，I stopped comparing myself with actresses and models and looking for things that were wrong with my face or body.　 Instead，I made a list of the things I liked about myself.By being positive about myself and my body，I became both happier and healthier.  本句是复合句，其中“comparing myself...models”和“looking for...body”两个动名词短语作stopped的宾语。that引导定语从句，修饰先行词things，that在从句中作主语。 变得积极乐观 我总是想变得像电视里那些苗条的女孩一样，虽然我知道那是不可能的。我担心我的体重，在网上读到的每一种新的节食方法我都去尝试。我尝试了无脂肪、低脂肪、5∶2饮食法、只吃香蕉、不吃香蕉——我也几近疯狂。 之后我读到了一篇文章，里面提到不应该问自己“我胖吗？”，而要问自己“我健康吗？”。我根本不知道一个字母会有这么大的影响！当我开始关注健康而非体重时，情况就开始发生了变化。我不会说“我想减掉3公斤”，而会说“我想在8分钟内跑2千米”或者“我希望能做30个俯卧撑”。我没有舍弃我喜欢的食物，而是在我的餐食中增加了健康的食物。我可能偶尔还是会吃个汉堡，但(同时)我会再吃一份沙拉或者一个苹果。 最后，我不再拿我自己和女演员、模特作比较，也不去找我的脸上和身体上有什么问题了。相反，我把我喜欢自己的地方列了一份清单。通过对自己和自己的身体保持积极的心态，我变得更快乐、也更健康了。 [重点单词] 1．　positive　 adj. 积极的；正面的；乐观的；肯定的 2．　slim　 adj. 苗条的；单薄的 3．　diet　 n. 规定饮食；日常饮食vi.节食 4．　pushup　 n. 俯卧撑 5．　error　 n. 错误；差错 6．　jog　 v. 慢跑→　jog　 n. 慢跑 →　jogging　 n. 慢跑运动 7．　stress　 vt.强调；使焦虑不安→　stressful/stressed　 adj. 有压力的 [重点短语] 1．　make a difference　　有作用或影响 2．　rather than　　而不是 3．　cut...out　　剪下；停止做 4．　now and then　　偶尔；有时 5．　compare...with/to　　与……比较 [重点句型] 1. 试译：　参加比赛的孩子将学会如何对待失败，因为即使他们努力掌握运动所需要的技能也不能意味着他们一定会赢　。 2. 试译：　在体育比赛中，假装摔倒或受伤是没用的，因为最终观众会看穿的　。 3. 试译：　本周，我们五人学生小组做了一个调查，看看我们学生有什么样的体育爱好和需求　。 1．(教材P42)I worried about my weight and tried every new diet I read about online. 我担心我的体重，于是尝试了我在网上看到的每一种(能减肥的)饮食。　diet n. 饮食，日常饮食　vi.节食 ◆[佳句感知] (1)The old man keeps a balanced diet. 这位老人保持均衡饮食。 (2)Never give her chocolate；she is on a diet. 别给她巧克力；她在节食。 [归纳拓展]　go on a diet　节食(表动作) be on a diet　节食(表状态) ◆[佳句背诵] I really ought to go on a diet.I've put on so much weight since I gave up jogging. 我真应该节食了。自从我放弃慢跑后，我的体重已经增加了很多。 ◆[即学活用] 单句语法填空 ①The girl is 　on　 a diet，hoping to become slimmer. ②She is always 　dieting　(diet)but she never seems to lose any weight. 2．(教材P42)I had no idea a letter could make such a difference! 我不知道一封信竟能有这么大的影响！　make a difference 有影响/有关系 ◆[佳句感知] (1)Everyone can make a difference to our environment. 每个人都可为我们的环境出一把力。 (2)Luckily，my teacher sensed my problem，telling me that every small thing in life can make a difference. 幸运地是，我的老师意识到了我的问题，告诉我每件小事都会产生很大的影响。 [归纳拓展]　make no difference　没有影响/关系 make some difference　有一些影响/关系 It makes a difference to sb.＋wh－　从句 ……对某人来说有影响/有关系 注意：difference前可以加上big，great等形容词，表示程度。 ◆[即学活用] 单句语法填空 ①Changing school made a big difference 　to　 my life. ②　It　 makes no difference to me whether he comes or not. 完成句子 ③Whether he will come or not 　makes no difference to　 our party. 他是否会来对我们的聚会没有影响。 3．(教材P42)Once I started thinking about fitness rather than weight，things began to change. 一旦我开始考虑健康而不是体重的时候，事情开始发生变化。　rather than 而不是 ◆[佳句感知] (1)Who leaves a voice mail message rather than texts you?

Ⅰ.阅读理解 “Bill，you never miss！”Joe said admiringly.“Unless I'm in a real game，”Bill complained.“Then I miss all the time.”Joe knew that Bill was right.Bill performed much better when he was having fun with Joe in the school yard than he did when he was playing for the school team in front of a large crowd.“Maybe you just need to practice more，”Joe suggested.“But I practice all the time with you！”Bill objected.He shook his head.“I just can't play well when people are watching me.”“You play well when I'm watching，”Joe pointed out.“That's because I've known you since we were five years old，”Bill said with a smile.“I'm just not comfortable playing when other people are around.”Joe nodded and understood，but he also had an idea. The next day Joe and Bill met in the school yard again to practice.After a few minutes，Joe excused himself.“Practice without me，”Joe said to his friend.“I'll be back in a minute.” Joe hurried through the school building，gathering together whomever he could find－two students，a math teacher，two secretaries，and a janitor(看门人)．When Joe explained why he needed them，everyone was happy to help.Joe reminded the group to stay quiet as they all went toward the school's basketball court.As Joe had hoped，Bill was still practicing basketball.He made five baskets in a row without noticing the silent people standing behind him. “Hey，Bill！”Joe called out finally.Bill turned.A look of surprise came over his face.“I just wanted to show you that you could play well with people watching you，”Joe said.“Now you'll have nothing to worry about for the next game！” [语篇解读]　本文是一篇记叙文。讲述了Bill在众人面前打篮球时无法正常发挥，但是他的朋友Joe努力想办法帮助他克服这一困难的故事。 1．What would be the best title for the story?

My first cross­country coach told me that every race is run with patience and determination.I've carried this advice with me for hundreds of miles.I especially remember the 5 miles of running in one race，where his words encouraged me a lot. That day the weather was perfect.I and dozens of runners gathered at the starting line to do some last­minute preparations for the running.Then，we lined up and got ready to start.There was a brief moment before the gun gave a signal of running.In that moment of great stress，I determined to push myself to run as fast as possible，hoping to make my coach proud，who was waiting for me at the finish line.When the sound of “Bang” came up，we were off. Running between runners，I managed to work my way up in the first 400 meters and passed many racers on my sides.But out of good sportsmanship，we each said a “good job” or “keep up” to every person we passed.Although we were competitors，running was a connection we all shared. The first mile passed quickly in a feeling of excitement.It was not challenging in the beginning of the running.But I knew it would be harder and harder in the following miles.I made full use of the running skills that my coach had taught me.I checked that I was doing everything right，breathing in through my nose，keeping my hands relaxed and pumping(快速摆动) my arms.However，the shadow of tiredness danced before me.Anyway I tried to push it out of my mind. With time going by，the competition became fiercer.Every runner tried their best to run in order to gain a good place in the race.Audience along the track shouted and cheered us. 注意： 1．续写词数应为150左右； 2．请按如下格式在相应位置作答。 Eventually I reached the final mile.___________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Unfortunately，I suddenly fell down.__________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ [参考范文] 　Eventually I reached the final mile.　 It was then that I felt extremely tired and sweat fell down my face.Many runners in the race had fallen behind，but I refused to be one of them.Instead，I chose to pump my legs a little faster and push myself a little harder.As the last half mile was near，the number of people along the track increased.Around the next corner，I could see my coach waving to me in great excitement.I tried to run faster. 　Unfortunately，I suddenly fell down.　I felt great pain and discouraged.Just at that moment，the audience shouted，“Come on，girl！”“Watch out！” “Keep up！” Meanwhile，a runner behind me came to me and gave me a lift.I was really grateful and encouraged.I stood up and ran for the final 400 meters.When I finally sailed over the finish line，I nearly cried with relief.I won the third place in the race.My coach was proud of me and I felt great too. 健康生活 [素养提升] 一、文体特点 健康生活类话题作文还可能围绕“体育锻炼的重要性；健康与财富哪一个更重要；学生健康状况调查及改善建议”等方面命题，这类话题属于说明议论文或夹叙夹议的文章范畴，常使用现在时态和过去时态；陈述论点说明情况多使用现在时态，记叙典型事例常用过去的时态，对典型事例发表看法使用一般时态。 二、语言特点 健康生活类文章，贴近日常生活，因此语言使用要接地气，简练易懂，确凿有说服力。引语、数字以及背景材料必须有据可查。语句不易过长、复杂。时态通常为一般现在时，对于预期结果使用一般将来时。以第三人称为主。 三、结构特点 健康生活类话题作文主要围绕以下几个方面写作： (1)健康生活的必要性、重要性。 (2)如何才能健康生活：加强锻炼、注意饮食、均衡营养、养成良好的生活习惯等。 (3)个人对健康生活的认识、如何从自我做起，如何制定计划改变不良生活习惯等。 四、知识储备 ★常用表达句式 (1)Nowadays more and more people are concerned about their health. 当今，越来越多的人关心自己的健康。 (2)The majority of people eat too much fat and not enough fibre，which does great harm to their health. 大多数人摄入的脂肪太多纤维不足，这对他们的健康很有害。 (3)A healthy diet consists of eating a variety of foods rich in vitamins，fibre and mineral，and low in fat and calories. 健康饮食包括饮食多样化，吃富含维生素、纤维和矿物质而脂肪和热量含量低的食物。 (4)Eating in a healthy way and exercising regularly are the key to keeping healthy. 健康饮食和经常运动是保持健康的关键。 (5)Taking exercise every day helps us build a strong body. 每天进行运动有助于强身健体。 (6)Regular exercise is an essential part of keeping healthy. 经常运动是保持健康的必要部分。 (7)By eating properly and exercising regularly，you can keep your body at a proper weight and keep healthy. 通过合理饮食和经常运动，你可以保持适当的体重且身体健康。 (8)We have to develop a regular eating habit and keep a balanced diet. 我们必须养成规则饮食的习惯并且保持平衡饮食。 (9)Finally，getting rid of bad habits like smoking and drinking alcohol is also an important way to keep healthy. 最后，摆脱像抽烟、喝酒这样的坏习惯也是保持健康的重要手段。 [典题指导] 为提高公民的健康意识，普及健康的知识，提高生活技能和生命质量，卫生部疾控防治中心、全国爱卫会共同发起了“全民健康生活方式行动”(National Healthy Life Style)。该活动的主要内容是：日行一万步，吃动两平衡。请根据以上内容，结合生活实际，用英语写一篇短文，阐明自己的观点。内容包括： 1．行动的内容和目的； 2．行动的背景、原因； 3．行动的预期效果。 ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ►审题谋篇 首段：总体阐述活动内容及目的 中段：叙述存在的问题及危害 尾段：发出诚恳号召，增强体质。 ►[佳作展示] At present，a campaign called National Healthy Life Style was carried out throughout the country.This campaign calls on people to take more exercise instead of eating much.
