Let $p : E \to B$ be a (real for example) vector bundle. It's locally trivial, meaning that if you take a small open set $U \subset B$, then you can find an isomorphism $\varphi : p^{-1}(U) \cong U \times \mathbb{R}^n$, compatible with $p$ (meaning that $\varphi(\xi) = (p(\xi), \text{something})$). Now a section $s : B \to E$ of $p$ is a map such that \$p ...
