Our annual sports day is very close. We need to start making preparation for a successful event. First, we will make some volunteer groups to arrange this sports event smoothly. Next, we will invite our teachers and other guests to present at the event. Then, we will inform all the students and encourage them to participate on time. After that, we will work with volunteer groups to decorate the playground with colourful balloons. Finally, we will buy some prizes for the winners.
