They have a lovely flower which follows the sun.

它们的花是向阳的。

Moreover, sheltering the mirrors from the wind allows those mirrors to be a lot lighter, making them both cheap to build and ship, and easier to turn in order to follow the sun.

此外，为保护反光镜免受风的侵蚀，准许这些反光镜重量要轻的多，使得它们既建造便宜也容易运输，而且为了跟进太阳而更容易转向。

They were also annoying to scientists like Galileo, Kepler, and Halley, who all had theories about why the wind blew to the southwest: Did the wind somehow follow the sun from morning till night?

这也常常困扰了像伽利略、开普乐、哈雷这样的科学家，他们都有关于为什么风往西南吹的理论：难道风向在某种程度上是整日跟随太阳的？
