# Fuels, the Sun and saving energy, sentence 1

<!-- .ven lang=en -->
A fire needs three things, fuel, oxygen and heat, and taking away any one puts it out, which is how a fire blanket works: it keeps the oxygen away.

<!-- .vintro -->
**Who acts:** fire, taking, blanket · **What happens:** need, take away, put out, be, keep away · **To what, where:** three things, one, fire, oxygen

<!-- .vabout -->
This is a sentence of the lesson «Fuels, the Sun and saving energy» of the physics 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 (fire, taking, blanket), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R6-punct-agree ×1, R7-rel-agree ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
