摘要
<正>Our class is going to have a picnic at Mandelson Park next Wednesday. We’re going to leave the school at 7:45 in the morning. We’re going to take the school bus. We need to bring our own drinks and food, but we can’t barbecue there.We are going to arrive at the park around 9:00. First we play some games. We can play ball games but mustn’t play in the stream.
