Just then, Ms Miles, the gym teacher, brought out a bunch of short jump ropes.

就在这时，体育老师迈尔斯女士拿出了一捆短跳绳。

Their jump ropes were too short.

他们的跳绳太短了。

I have two jump ropes, one long jump rope and one short jump rope.

我有两个跳绳，一根长的，一根短的。

They climb up ropes and jump down again and play with each other like small children.

Jump-ropes and resistance bands are easy to sneak into a suitcase.

跳绳和阻力带都非常容易塞进行李箱。
