are some vertical segments, i.e. $r$ decreases monotonically from 1 to $1+{9\over 2}w_X(1+w_X)$ while $s$ remains constant at $1+w_X$ [@sahni; @alam]. The quintessence (inverse power law) tracker models have typical trajectories similar to arcs of an upward parabola lying in the regions $s>0,~r<1$ [@sahni; @alam]. The holographic dark energy scenario ($c=1$ case), as shown in [@holosr], commences its evolution from $s=2/3,~r=1$, through an arc segment, and ends it at the $\Lambda$CDM fixed point ($s=0,~r=1$) in the future. The coupled quintessence models and Quintom models exhibit more complicated trajectories as shown in Refs. [@quintomsr; @zx]. Now from the Figs. 5 and 6 of this paper, we can see the statefinder trajectories of the NGCG model. In Fig.5 we see the cases under the fixed $\alpha$, where the GCG model ($w_X=-1$) exhibits a complete downward parabola, while the general cases ($w_X\neq -1$) correspond to some broken parabolas. The statefinder trajectory commences its evolution from $s=1+(1+\alpha)w_X,~r=1$ at $t\rightarrow 0$ to $s=1+w_X,~r=1+{9\over 2}w_X(1+w_X)$ at $t\rightarrow \infty$, through the curve. Today’s statefinder point locates at $s_0=1+w^{(e)}_{X0}$, $r_0=1+{9\over
2}w_X\Omega_X^0(1+w^{(e)}_{X0})$, where $w^{(e)}_{X0}=w_X+\alpha
w_X(1-\Omega_X^0-\Omega_b^0)/(1-\Omega_b^0)$. The “distance” from the NGCG model to the $\Lambda$CDM scenario can be measured directly in the statefinder plane. Note that under a positive $\alpha$,
