All these lines of the web are made of smooth elastic threads of silk.

这些蛛网全部由极富弹性的柔顺丝线组成。

This is because elastic threads that helped socks hug the leg and stay up were not yet invented.

这是因为当时还没有发明帮助袜子包裹住腿部并撑起的弹性线。

I could almost feel the miles between us shrinking, as if we were at two ends of some invisible elastic thread.

我几乎能感觉到我们之间的距离在缩小，就好像我们处在一根看不见的弹性线的两端。
