Step3: Read the dialogue sentence by sentence, pay attention these language notes.

 2: How often do you exercise every day?
Think about: 对于how often 提问的特殊问句应怎么回答？
eg: How often do you brush your teeth?
 3: wake up  醒来
eg: Lily wakes up at 7:00 ,but gets up at 7:30.
Wake sb. up 叫醒某人 
Time for breakfast. ____________________(把丽丽叫醒)。
4: Why does it take longer to go home?
   it takes some time to do sth.
eg: It takes me one hour to do my homework.
5: I need to eat fewer donuts?    need to do sth.
6: fewer 是few“不多，少数”的比较级，few 倾向于否定，表示虽“有”但“少”，常译为“几乎没有”。
   few        修饰可数名词      表否定
  a few       修饰可数名词      表肯定
   little       修饰不可数名词     表否定
  a little      修饰不可数名词     表肯定
7：You have to do some sports for exercise!
 have to “必须，不得不”指客观需要，常用have to do sth.
eg:下雨了，我们不得不赶紧回家。
8: Exercise helps make your body healthy and strong.
help make 是两个动词的连用。通常一个动词之后再跟一个动词时，第二个动词要变为 to do的形式，或v-ing形式，多不跟动词原型，但help例外，后面可以跟to do 的形式，也可跟动词原型。
help sb. (to) do sth.
8：Walking to school is exercise. Running is exercise.
“都属于v-ing形式或v-ing形式短语做主语的结构，表示做某件事情，而不是直接说做某个动作。V-ing做主语位于动词应用单数。
eg: _________________(学习新单词)is very important for us.
