Pools, lakes and ice, sentence 3

Ice on a pond may look solid but can be thin, especially near streams, bridges and the edges; children go on ice only where an adult has checked it is thick enough, and in the UK and Ireland ice is almost never safe to walk on.

Who acts: Ice, children, adult · What happens: look, be, go, check, not be, walk on · To what, where: ice, UK

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): R7-rel-agree ×2. 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.
