  The truncated Euler-Maruyama (EM) method is proposed to approximate a class
of non-autonomous stochastic differential equations (SDEs) with the H\"older
continuity in the temporal variable and the super-linear growth in the state
variable. The strong convergence with the convergence rate is proved. Moreover,
the strong convergence of the truncated EM method for a class of highly
non-linear time-changed SDEs is studied.
