Power stations and the grid, sentence 1
In a power station, steam, gas, wind or falling water spins a turbine, a wheel of blades, and the turbine turns a generator, where magnets whirl past coils of copper wire and push electricity along them.
Who acts: steam, turbine, magnets · What happens: fall, spin, turn, whirl, push · To what, where: turbine, power station, generator, coils, electricity
This is a sentence of the lesson «Power stations and the grid» of the technology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (steam, turbine, magnets), what happens, when and where, as Mova's frames read it from the tree.
