But planting this many trees, just the genetically UNALTERED kind - has  become surprisingly controversial.

但种植这么多树，而且只是基因未改变的树，却引起了令人惊讶的争议。

The thirteenth-century cathedral towered above a sixteenth-century mass of tiled roofs, ending abruptly in walls and a landscape that had not changed.

十三世纪的大教堂耸立在十六世纪的大量瓦片屋顶之上， 突然终止于墙壁和未改变的景观。

Judging from the past, we may safely infer that not one living species will transmit its unaltered likeness to a distinct futurity.

从过去的情况来看， 我们可以有把握地推断， 有一个生物物种会将未改变的相似性传递到一个截然不同的未来。

They're genetically modified mice that have twice the muscle mass than unaltered mice, and 40 of them were recently sent into space for a study on muscle mass.

他们的基因发生了改变，比起未改变的老鼠他们的肌肉翻倍，最40只因肌肉研究而被送到了太空。

So what we see as a unit sphere in our 3d space represents the only unaltered part of the hypersphere of quaternions getting projected down on to us.

因此，我们在 3d 空间看到的单位球体代表了投射到我们身上的四元数超球面唯一未改变的部分。

And even while their plant machinery is being co-opted as an enzyme-making factory, the plants suffer no reduction in yield while grown out in the field compared with unaltered plants.

即使他们的植物机械被选作酶制造工厂，与未改变的植物相比， 这些植物在田间种植时的产量也有降低。

The idea was that we could go and look at the masked-tile locations and then look at that same location in other unaltered satellite imagery and see what was there.

我们的想法是，我们可以去看看蒙版瓷砖的位置，然后在他未改变的卫星图像查看相同的位置，看看那里有什么。

The other nine species (marked by capital letters) of our original genus, may for long but unequal periods continue to transmit unaltered descendants; and this is shown in the diagram by the dotted lines unequally prolonged upwards.

我们原始属的他九个物种（ 以大写字母标记）可能会在很长一段时间内但不平等地继续传播未改变的后代；这在图由向上不等长的虚线表示。
