We all hope you can join us. Here is the schedule. We are to meet at the school gate at 8 o'clock this Saturday morning. Since we'll cycle there and work in the field, you'd better wear casual clothes and comfortable shoes. It would be better if you could bring some necessary tools. Bes ides, we'll have a picnic
