英语荡秋千怎么说

In English, a seesaw is often referred to as a "teeter-totter." This term comes from the two words "teeter," which means to move or sway unsteadily, and "totter," which means to walk unsteadily or to sway from side to side. So a teeter-totter is a device that moves unsteadily from side to side, like a seesaw.
