My friend, John, has had a few problems with his health. He didn't feel well, (31) he told his parents about that. His mum said, "You should eat more vegetables. You shouldn't eat (32) every day." His dad said, "You should go to bed earlier. You (33) stay up so late at night." He phoned me and told me about the problems. I said, "Don't play so many computer games. Go outside and play football."
He didn't go to school last week. He went to (34) the doctor. The doctor said, "You should stay at home for a week. Don't go out and don't turn on your computer."
At school today, he looked sad. We asked him, "What's wrong? You should be happy. You weren't here last week."
John is (35) his school work from last week. He's not happy at all.

KEEPING OUR TEETH HEALTHY
It's very important to have healthy teeth. Good teeth help us chew our food. They also help us look nice. How does a tooth go bad? The decay begins in a little crack in the enamel covering of the tooth. This happens after germs and bit of food have collected there. Then the decay slowly spreads inside to the tooth. Eventually, poison goes into the blood, and we may feel quite ill.
How can we keep our teeth healthy? First, we ought to visit the dentist twice a year. He can fill the small holes in our teeth before they destroy the teeth. He can examine our teeth to check that they are growing in the right way.
Secondly, we should brush our teeth with a toothbrush and fluoride toothpaste at least twice a day once after the breakfast and once before we go to bed. We can also use wooden toothpicks to clean between our teeth after a meal.
Thirdly, we should eat food that is good for our teeth and our body: milk, cheese, fish, brown bread, potatoes, red rice, raw vegetables, and fresh fruits. Chocolates, sweets, biscuits and cakes are bad, especially when we eat them between meals. They are harmful because they stick to our teeth and cause decay.
