Oliver and his friends want to (make) a GREEN weekend plan. Oliver will (go) to the bookstore to buy some books this Saturday. He is going to take a subway this time. Sarah is going to the park. Her parents often (take) her to the park by car. Wu Binbin is going to take a (dance) class. He's going there on foot this Sunday. It will take him about fifteen minutes. Do you like their GREEN weekend plans? Why not (join) them? Come on!
