1、The stream of positive particles that meets the surge of electrons from the cloud often arises from a tall pointed structure such as a metal flagpole or a tower.───来自云层的电子流与正粒子流相遇，而这些正粒子流通常来自于高而尖的结构，如金属旗杆或塔。
2、Atoms are composed of protons and neutrons in a nucleus surrounded by a cloud of electrons .───原子由中子和质子构成，它们位于核子中，核子又被电子云所包围。
3、An atom consists of a cloud of electrons surrounding a small, dense nucleus of protons and neutrons.───原子由云围绕一个小而密的原子核的质子和中子的组成。
4、formation of the channel is initiated when electrons surge from the cloud base toward the ground.───当电子从云层底部涌向地面时，通道就开始形成了。
5、Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.───原子是由质子和中子组成的原子核与围绕原子核的电子云构成的。
6、Then a strong current of electrons follows that path from the cloud to the ground, and it is that current that illuminates the channel as the lightning we see.───然后一股强大的电子电流沿着这条路径，从云层到达地面，正是这种电流像我们看到的闪电一样照亮了通道。
7、These days America fights not in a fog of war but, as one senior air force officer puts it, in a "huge cloud of electrons" .───如今，美国已经不是在战争的硝烟中作战，而是如一位空军高级官员所谓的，是在“厚厚的电子云”中作战。
