So how do we do this? 那么我们如何做到这一点？
It's not like we have some magic electromagnetic shrink ray, like professor Wayne Szalinski used in "Honey, I Shrunk the Kids" 并不是说我们拥有某些 有魔力的电磁收缩射线, 就像韦恩·萨林斯基教授在 “亲爱的,我把孩子们缩小了”里面

We then cover it with a mask that has a pattern on top of it of fine lines and features that are going to make the phone work the way that we want it to. 然后我们用一张膜把它盖住, 膜上面有一些 用来定制手机功能的 细线和特性的图案。
We then expose a bright light and shine it through this mask, which creates a shadow of that pattern on the surface. 接着我们让基底暴露在 一束明亮的光下, 在表面上留下一个阴影的图案。
expose:v.揭露,揭发;使曝光;显示;

And for that, we have to use a chemical solution called the developer. 要实现这个目的, 我们必须使用一种 叫显影剂的化学溶液。
Now the developer is special. 这种显影剂比较特别。
What it can do is take all of the nonexposed areas and remove them selectively , leaving behind clean fine lines and features, and making our miniaturized devices work. 它的作用是将没有曝光的区域 有选择性的去除掉, 留下干净的线条和特征, 让我们的小型设备正常工作。
selectively:adv.有选择地; miniaturized:小型化;
So, we've used chemistry now to build up our devices, and we've used it to shrink down our devices. 所以,现在我们已经使用 化学打造出了我们的设备, 也用它缩小了我们的设备。

opposed:adj.强烈反对; v.反对(计划、政策等); (oppose的过去分词和过去式)
But once true 5G is here, it's going to be a lot more than how many movies we can put on our device. 但是一旦 5G 真的来了, 比起我们可以 放多少部电影在手机里, 它实际上有更深远的意义。
So the question is, why is true 5G not here? 那么问题来了, 为什么真正的 5G 还没来？
And I'll let you in on a little secret. 我想与你们分享一个小秘密。
