Playing on the seesaw

玩跷跷板───Playing on the seesaw

I'm playing on the seesaw with an older girl in the park!───我正跟公园里的大姐姐一起玩翘翘板呢！

I'm playing on the seesaw.───我正在公园里玩跷跷板。

The children are playing on the seesaw.───孩子们在玩跷跷板。

We soared high into the sky on it and were then cast down and went up again. We kept on playing on the seesaw a hundred times.───接下来又去玩跷跷板，都快要弹到天上去了，掉下来又弹上去，上上下下接连不停，足足玩了一百下才停止。

Some kids are playing on the slide, some are playing with balls, and some are playing on the seesaw.───有些孩子在玩滑梯，有的在玩球，有的在玩跷跷板。
