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树，却引起了令人惊讶争议。

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

十三世教堂耸立在十六世量瓦片屋顶之上， 突然终止于墙壁和未改变景观。

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

从过去情况来看， 我们可以有把握地推断， 有一个生物物种会将其未改变相似性传递到一个截然不同未来。

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.

他们基因发生了改变，比起未改变他们肌肉翻倍，最近其中40只因肌肉研究而被送到了太空中。

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 空间中看到单位球体代表了投射到我们身上四元数超球面中唯一未改变部分。

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.

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

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.

我们想法是，我们可以去看看蒙版瓷砖位置，然后在其他未改变卫星图像中查看相同位置，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.

我们原始属其他九个物种（ 以写字母标记）可能会在很长一段时间内但不平等地继续传播未改变后代；这在图中由向上不等长虚线表示。
