My name is Nick and I am from America. I am eleven years old. In my family all members like to eat delicious food, but not always junk food.

Now I have a problem I am 120 kg. I usually have tea and cakes for breakfast and sometimes I have sausages and eggs too. At 11 o’clock I often eat a bar of chocolate and some biscuits or a sandwich. I usually have a big lunch, for example sausages and chips. And then I have ice cream, which I love. When I watch TV I have tea and a sandwich. For dinner usually I have meat and potatoes. Before I go to bed usually I have a cup of hot chocolate and some small cakes.

My friends play outside and often invite me, but it`s too hard for me to move & I always sit at home playing with my mobile device. Once a week I walk in the park & often sit on the chair there.

Do you know the proverb ‘You are what you eat’? It means that if you eat healthy food you can be healthy. You should not eat a lot of biscuits or chips, for example. You can eat your favourite foods, like hamburgers, but don’t eat a lot of them. Eat more fresh food and vegetables.

Read the text and answer the questions. Write full answers.

1. What does Nick eat for breakfast? _________

2. How often does he go to the park? _________

3. Does he play outside? _________

4. What does he eat before to go to bed? _________

5. What do you recommend to Nick? ДАЮ 55 БАЛЛОВ
