A: M: Mary, would you like to have a picnic with us this Sunday?
Problem: Given the question: Julie: I can't wait to see Canada, Susan, but I'm somehow scared of the journey. My husband insists on flying but I want to sail. Planes make me nervous. Susan: There's nothing to be frightened. How many planes fly across the Atlantic every day? Julie: I've no idea. Hundreds, I suppose. But any accident in a flight will lead to tragedy. Susan: And how often do you hear of a crash? Once or twice a year? Julie: Yes, but planes fly so high and fast that once was enough. Susan: Look, there are more road casualties per day than air deaths per year. Air transport is really safe compared with road transport. Julie: I'd still prefer to go by sea. Ships may not travel fast and at least you can relax. I'd love a trip on a luxury liner like the Queen Elizabeth II. Susan: It's fine if you're a good sailor. But have you ever traveled far in a rough sea? Julie: No. I've only been in a boat once. I sailed down the River Thames on a sightseeing tour. But in many eases I'd rather to be sea - sick than dead.

Q: Mum: I'm getting something ready for tomorrow. Tomorrow is Tre e-planting Day. Li Ming: Tree-planting Day? What do people do on this day, Mum? Mum: Many, many people will go and plant trees. Li Ming: Why do they do tha t? Mum: To make the earth more beautiful. And to make our life better. Li Ming: But I often see people on TV cut down many big trees. Why do they do that, Mum? Mum: Hm, to make paper, houses, and to make our life better. Li Ming: To make our life better, too? I just don't understand. Mum, why do many people go and plant trees on the same day? Mum: Oh, my dear son. It's hard to explain to you. When you grow up, you will understand. Just remember trees are very important to us. What was said before this conversation?
