  Applying logarithmic transformations along 2-tori, we construct a generalized
complex structure J_n with n type changing luci for every $n\geq 0$ on genus
1-Lefschetz fibrations with a cusp neighborhood, which include elliptic
surfaces with non-zero euler characteristic. Applying a technique of broken
Lefschetz fibrations, we further obtain twisted generalized complex structures
with arbitrary large numbers of connected components of type changing loci on
the manifold which is obtained from a symplectic manifold by logarithmic
transformations of multiplicity 0 on a symplectic 2-torus with trivial normal
bundle. The connected sums $(2m+1)S^2\times S^2$ for $m\geq 0$, $(2n-1)\C P^2#
(10n-1)\ol{\C P^2}$ and $S^1\times S^3$ admit twisted generalized complex
structures J_n with n type changing luci for arbitrary large n.
