2、调理天气。我们将逐渐学会如何预测人类活动对地球、对全球气候以及对生态系统所带来的影响。拥有了这些知识，人们将更乐意用它来对我们这个星球的动作进行管理。我们将拥有人脑的“路线图”。这是21世纪的一个真正的“边缘领域”：人脑是我们所知道的人体最复杂的系统。它含有1000多亿个神经元（大概是银河系中星星的数量），其中每一个神经元又连接到另外1000多种其它神经元。21世纪的早期，我们将应用先进的磁共振成像形式绘制详细的人脑神经元动作图。当你读一个词，说一个词，想一个词以及做其它事情的时候，我们将能肯定地说出哪些神经元在工作。👉 课文词汇脱氧核糖核酸 DNA 遗传医学 genetic

It contains about 100 billion neurons (roughly the number of stars in the Milky Way), each connected to as many as 1,000 others.

Early in the 21st century, we will use advanced forms of magnetic resonance imaging to produce detailed maps of the neurons in operation (to map / plot / draw in detail the operation of the neurons). We will be able to say with certainty which ones are working when you read a word, when you say a word, when you think about a work, and so on. (Well soon know for sure that neurons are activated / are working when, for instance, we read, speak or simply think about a word.)专心-专注-专业
