Get off the sofa!
Sure, it is comfortable to sit on the sofa and watch TV. But doctors say you should get off the sofa. To keep fit, you have to walk at least 10,000 steps every day. In the past, people’s jobs required ❷ more physical effort ❸. They often had to walk for miles every day. When farmers were working in the fields, they were keeping fit at the same time. Think about it: Do you get the same amount of exercise today as they did in the past?
Writing
Read the passage in Activity 2 again. Think of one more example of what you should or should not do for each rule.
