Unit 79：Stroll after supper第79单元：晚饭后散个步After-dinner snacks are a weakness for many of us.很多人都有在晚饭后来份点心的弱点。Avoid them and get a little exercise while you're at it by taking a walk after your meal.饭后想吃点心时，可以做点散步的小运动来避开点心。We're not talking about speedwalking,just a nice,pleasant stroll around the block to clear your mind and aid your digestion.我说的不是快走，而是绕着居家四周舒适、愉快地漫步，藉此可以让头脑清醒，也有助于消化。
