  We present a new input parameter set of the Pagel model (Pagel & Tautvai$\rm
\breve{s}$ien$\rm \dot{e}$ 1998) for the Large Magellanic Cloud (LMC) in order
to reproduce the observations, including the star formation rate (SFR) history.
It is concluded that the probability for (3-8)$M_{\odot}$ stars to explode as
SNe Ia has to be quite high ($\sim 0.17$) in the LMC. As a result, a steep
initial mass function (IMF) slope and existence of the outflow are not needed
in order to attain the low [O/Fe] ratio in the LMC. As for the current
supernova ratio, a high ratio ($\sim 1.3$) is concluded by the new parameter
set, which is consistent with the recent X-ray observations.
