But your brain gets so many external signals that it can't process it all at once and so it uses context to craft what you're hearing.

但是你的大脑接收到如此多的外部信号，以至于它不能同时处理所有的信号，所以它会使用语境来展示你听到的东西。

Now they are trying to figure out what molecular signaling processes activate those seed-building genes in resurrection plants — and how to reproduce them in crops.

现在他们正试图弄清楚是什么分子信号过程激活了复活植物中的这些种子构建基因——以及如何在作物中繁殖它们。
