Exercise helps make your body healthy and strong. Language points 1. Riding a bike is exercise. 骑自行车是锻炼。 句中的主语 riding a bike 是一个动名词短语。 其中riding 是动名词形式，起名词的作用，作主语时，谓语动词用第三人称单数形式。 例：吃蔬菜对你有好处。 Eating vegetables is good for you. 动名词在句中除了可以做主语外，还可以充当其他句子成分，如： （1）作表语，放在be动词的后面。 例：我的爱好是画画。 My hobby is drawing. （2）作宾语，放在实义动词的后面。 例：我喜欢打乒乓球。 I like playing ping-pong. （3）作定语，修饰名词，放在名词之前。 例：这是一个游泳池。 It’s a swimming pool. 2. exercise 作名词时，既作不可数名词，意为“锻炼”，也可作可数名词，意为“练习，练习题” 。 do exercise 做锻炼（不可数名词） do morning exercises 做早操（可数名词） 拓展：exercise还可作动词，意为“锻炼”。 do eye exercises 做眼保健操 例：我一天锻炼60分钟。 I exercise sixty minutes a day. ②How many minutes does Danny exercise? How often do you exercise, Danny? I walk to school in the morning, and I walk home after school. That’s twice a day. How many minutes do you walk? About five minutes. I think you need about an hour of exercise a day, Danny! Okay! I’m going to watch more sports on TV! No, Danny! You have to play sports for exercise! Language points I walk to school in the morning, and I walk home after school. 我早上步行去学校，放学后步行回家。 walk to school ＝go to school on foot walk home＝go home on foot school 是地点名词，所以 walk 后面有介词to。 home 是表示地点副词，所以 walk 后面的介词to要省略。 步行回家 2. How many minutes do you walk? 你步行多少分钟？ How many 是对可数名词的数量提问； How much 是对不可数名词的数量提问。 询问某人做某事用多少分钟的句型： How many minutes + do (does) +人+动词原形+其他？ 3. I’m going to watch more sports on TV! 我会在电视上看更多的体育节目！ be + going to + 动词原形表示“计划、打算做某事”， 属于一般将来时态。 例：我打算明天跑步。 I’m going to run tomorrow. 4.
