| 释义 | trampoline (once / 38752 pages) n A trampoline is a piece of gym equipment that's made for bouncing. Some people have trampolines in their yards so they can bounce and flip whenever they want to, while others go to trampoline parks to fulfill their bouncing needs. Professional trampolines are extremely sturdy, made of a large piece of durable fabric stretched tightly across a raised frame of springs. It may appear that the surface of a trampoline is stretchy, but it's actually the springs that provide the bounce, not the fabric. Jumping on a trampoline can be dangerous, especially if there are several people doing it at the same time. Trampoline comes from the Spanish trampolin, "springboard."
