Mary, Tony, Anne and Eric all have their own ways to keep fit, and they follow sports rules well all weekdays. How do these four students exercise every day? Mary is a good swimmer. She swims in the swimming pool after school. How long does she stay there? It takes her about forty minutes to swim every time. She must put on her swimming suit and a safety belt before she jumps into water, and she can’t jump the queue to get into the pool. If you litter snacks or sweet rubbish in the pool area, you will make the place untidy and awful. Tony likes running best. His jacket is light and fits him well. How far is it from his home to the running track? It’s about one kilometer. He has to arrive at the track on time and practise running quietly without making loud noise. He doesn’t hang out with others while exercising; he focuses on his sports spirit all the time. He thinks running can build a strong body and help him relax after busy schoolwork. Anne enjoys playing ball games. She knows she must be polite and treat one another with respect when playing with teammates. She won’t lend her sports equipment to others carelessly, and she always picks up her things and carries them away after games. She guesses regular exercise can make people not unhappy at all; however, too much exercise will make you tired. Eric often walks to the forest park to do sports. In the park, there are many playful animals like foxes and giraffes. He feeds small birds with sandwich pieces, but he knows he must not kill any little wild animals, for they are in danger. He thinks looking after animals and doing sports together can lift our spirit. All sports places have strict rules, just like our school rules. You must follow the order and can’t break any rules. Dr. Li gives us good advice: if you feel untidy and weak, think about taking exercise every day. It can understand your tired feeling and make you become better day by day. Everything will turn great when you stick to sports and keep fit. 一、Unit3 核心词汇 & 配套 1、2 单元串联词汇核对（全文全覆盖） Unit3 专属核心词 fit adj. 健康的；v. 适合 运动 / 健康主题核心词汇（贯穿全文） swimmer, practise, relax, spirit, build, advice, understand, become, better, guess 承接 Unit2 校园 / 公共规则词汇（串联复用） arrive, on time, hallway, uniform, litter, polite, treat, respect, if, jacket, have to, everything, lend, sweet, snack, of course, mobile phone, turn off, queue, jump the queue, feed, leave, absent, quietly, put on, belt, noise, unhappy, awful, untidy, hang out, focus on, person, think about, Mary, Tony, Anne, Eric, Dr. 承接 Unit1 动物 / 自然拓展词汇（场景串联） fox, giraffe, playful, forest, sandwich, kill, in danger, look after, however, too many 二、单元 Grammar Focus 语法精讲 语法 1：How 引导三大特殊疑问句（单元核心考点） 1　 How 提问运动 / 出行方式 2　 原文例句：How do these four students exercise every day? 结构：How + do/does + 主语 + 动词原形...? 三单变形：How does Mary swim after school? 答句：主语 + 动词（三单变形）+ 运动方式 例：She swims in the swimming pool. 3　 How long 提问运动时长 4　 原文例句：How long does she stay there?
