At 7:30 on the morning, we gathered at the school gate and set off on a large bus．An hour later, we arrive at the Forest Park．Getting off, we started our journey at once.
First, we climbed the green hills and on the way tried their luck to hunt for hidden treasure．Next, we toured around the lake in the fortable boat．The beautiful scenery was really a feast for the eye．Then at noon time, we landed and settled at an open area, which we enjoyed a wonderful picnic．After eating, we sang and danced happy and played some interesting games．The day passed quickly．Finally it was time for us to return back．So at 3:00 pm, we cleaned the ground, made our way to the parking lot, getting on the bus and left.
It was really an exciting trip since we had long busy with our school work.on改为in 2．arrive改为arrived   3．their改为our        4．the改为a
