Dear Sir/Madam, I 1) (write) on behalf of Midfield School. Every year, our students 2) (choose) to do a project on an environmental problem. Then, they 3)
(work) to raise money to help solve this problem. We 4) (recently/see) your advertisements about protecting dolphins, so for the last few weeks we 5) (try) to learn about the dolphins that 6) (live) in he sea near our school. We 7) (already/be) on two boat trips and 8) (persuade) local fishermen to change their fishing nets because the ones they 9) (use) at the moment can trap dolphins. Could you please send the children some World Wildlife Fund posters to add to the presentations that they 10) (do) so far?
Yours faithfully,
J. Hopkins (Teacher)

Laura lives in a big city. If she lived in the country, she would have a dog. Laura shares a flat with three other girls. But if it were possible, she would live on her own. If she lived in the country, she would buy a little cottage, and she would grow her own flowers and vegetables. In town, she travels by underground and goes shopping in big department stores, but she doesn't like this at all. If she were in the country, she would ride her bike, and she would buy things in the little village shop. She loves walking and often goes for a walk in town, but the streets are noisy. In the country, she would walk across the fields with her dog.
