Semitruck tires aren't supposed to explode, but they do.

半挂卡车的轮胎其实不应该爆炸，但他们确实会。

First of all, a semitruck isn't falling out of the sky as part of its route.

首先，一辆半挂卡车的行进路线，它不是从天上掉下来的。

The molecular version of semitrucks are proteins aptly named motor proteins, that can walk along microtubules, dragging sometimes huge cargoes, like organelles, behind them.

半挂式卡车的分子版本则被贴切的称为“马达蛋白”，它们能在微管上行走，有时候在身后拖着大型“货物”，比如说细胞器。

There is now a semitruck company that's been stood up by Tesla and another that is going to be a hybrid with electricity and green hydrogen, so we'll see whether or not they can make it work in that application.

现在有一家由特斯拉成立的半挂卡车公司和另一家将成为电力和绿色氢的混合动力车的公司，因此我们将看看他们是否可以在该应用程序中发挥作用。
