Query: General Single Field Inflation with Large Positive Non-Gaussianity   Recent analysis of the WMAP three year data suggests
$f_{NL}^{local}\simeq86.8$ in the WMAP convention. It is necessary to make sure
whether general single field inflation can produce a large positive $f_{NL}$
before turning to other scenarios. We give some examples to generate a large
positive $f_{NL}^{equil}$ in general single field inflation. Our models are
different from ghost inflation. Due to the appearance of non-conventional
kinetic terms, $f_{NL}^{equil}\gg1$ can be realized in single field inflation.
