Query: Do long-cadence data of {\it Kepler} satellite capture the basic
  properties of flares ?   Flare research is becoming a burgeoning realm in the study of stellar
activity due to the launch of {\it Kepler} in 2009. {\it Kepler} provides data
with two time resolutions, i.e., the long-cadence (LC) data with a time
resolution of 30 minutes and the short-cadence(SC) data with a time resolution
of 1 minute, both of which can be used to study stellar flares. In this paper,
we search flares in light curves with both LC data and SC data, and compare
them in aspects of the true-flare rate, the flare energy, the flare amplitude,
and the flare duration. It is found that LC data systematically underestimated
the energies of flares by 25\%, and underestimated the amplitudes of flares by
60\% compared with SC flares. The duration are systematically overestimated by
50\% compared with SC flares. However, the above percentages are poorly
constrained and there is a lot of scatter. About 60\% SC flares have not been
detected by LC data. We investigate the limitation of LC data, and suggest that
although LC data cannot reflect the detailed profiles of flares, they also can
capture the basic properties of stellar flares.
