我们知道现实中不可能战无不胜，但我们一直在努力，因为我们相信我们能做到。

We know that in the real world it's not always possible, but we will try as hard as we can to do it.

youdao

但现实中不可能只有好路而没有差路、坏路，而且，你没有在泥泞道路上行走过，就难以获得在泥泞道路上行走的经验。

But in reality, it is impossible to have only good road but not bad road, bad road, but you do not walk up a muddy road on the lack of access to the muddy roads experience.

youdao

尽管现实中很多画面都不可能一一审视，但在事后可以随时取得。

Although much of the imagery may not be watched in real time, it can be stored for later retrieval.

youdao

That's something that only the mind can think about, that we don't actually have in the world, the empirical world itself.

那仅仅是心灵可以设想的东西,而在现实的经验世界中,却是不可能存在的

我们可与去探讨,二加一等于三的这个事实,但是我们不可能有一天真的碰到数字,在现实世界中碰到个叫"数字三"的东西
