  MicroBooNE (the Micro Booster Neutrino Experiment) is a short-baseline
neutrino experiment based on the technology of a liquid-argon time-projection
chamber (LArTPC), and has recently completed its first year of data-taking in
the Fermilab Booster Neutrino Beam. It aims to address the anomalous excess of
events with an electromagnetic final state in MiniBooNE, to measure
neutrino-argon interaction cross sections, and to provide relevant R\&D for the
future LArTPC experiments, such as DUNE. In these proceedings, we present the
first reconstructed energy spectrum of Michel electrons from cosmic muon
decays, the first kinematic distributions of the candidate muon tracks from
$\nu_{\mu}$-argon charged-current interactions, and a demonstration of an
electromagnetic shower reconstruction from $\pi^0$s produced by
$\nu_{\mu}$-argon charged-current interactions. The results demonstrate the
first fully automated reconstruction and selection algorithms in a large LArTPC
and serve as foundations for future measurements.
