What is exercise?Exercise helps make your body healthy and strong. Riding a bike is exercise. 骑自行车是锻炼。知识点 1动名词是非谓语动词形式的一种，起名词或动词的作用。动名词（短语）作主语易错点
提示动名词（短语）作主语时，谓语用第三人称单数形式。用法：例句：Playing football is exercise. 踢足球是锻炼。典例Eating vegetables ________ good for your body.
A. am B. is C. are B点拨：
本题考查主谓一致。动名词（短语）作主语时，谓语动词要用单三形式，所以选B。该题的陷阱选项是C，不要受vegetables是复数的影响，而误选are。这句话的主语是动名词短语，而不是vegetables。例句：Exercise is good for our body. (n.)
锻炼对我们的身体有好处。
She exercises in the morning every day. (v.)
她每天早晨锻炼。exercise /'eks?sa?z/ n．& v．锻炼；练习短语：do exercise进行锻炼 (不可数名词)
do morning exercises 做早操(可数名词)
do eye exercises 做眼睛保健操(可数名词)词形变化：exercise(原形)→exercises(第三人称单数)→ exercising(现在分词)→exercised(过去式)2. How many minutes does Danny exercise?How many minutes do you walk?
你步行多少分钟？知识点 2由how many引导的特殊疑问句，用来提问可数名词的数量。由how many引导的特殊疑问句易错点
提示how many后的名词必须用复数形式。how many引导的特殊疑问句的动词的单复数要和主语保持一致，而不是由其后名词的单复数决定的。How many ping--pong balls does Li Ming have?
李明有多少个乒乓球？例句：拓展how many与how much一样，也有“多少”的意思，但how much后接不可数名词，而how many后接可数名词复数。
例句：How many books do you need? 你需要多少本书？
How much juice do you have? 你有多少果汁？例句：—How many minutes are there in an hour?
一小时有多少分钟？
—Sixty minutes.六十分钟。minute/'m?n?t/ n. 分(钟)复数：minutes短语：wait a minute等一下second秒，minute 分，hour 小时错不了。魔法记忆：hour /'a??/ n．小时【四会】知识点 3There are twenty-four hours in a day.
一天有24小时。例句：发音：字母h不发音。同音异义词：our pron.我们的谱系记忆法：ouryour
你（们）的four
四hour
小时易错点
提示因为hour的首字母h 不发音，hour是以元音音素开头的单词，所以表达“一小时”用an hour。3. Let’s do it!3. Let’s do it!140three times a week90twice a week3. Let’s do it!350I like running, I run for 30 minutes every morning.
