What do you think are good eating habits?
What will happen if we don’t have good habbits?

which of them are junk foods? Why?
Or which of them are healthy foods? Why?

Step 4 Speaking
Everyone wants to be healthy and strong. But sometimes we are not feeling well. Ask:
What will you do if you don’t feel well?
Say: When we’re ill, we’d better go and see a doctor and the doctor will look over us and give us some advice. Now we’re going to practice some everyday English used by doctors and patients. Go through the useful expressions on P3.
Have the students look at the example above. Ask two students act as Dr Yang and Sharon and read the dialogue aloud. Have the other students underline some useful expressions they can find.
Go through the three situations with the students on P2. Ask them to choose one of them and make up a dialogue in pairs according to the example given and then act it out.
