In this paper, we study Cauchy problem of the two-dimensional chemotaxis-Navier-Stokes equations with partial diffusion. Taking advantage of a coupling structure of the equations and using the damping effect of the growth term $g(n)$, we obtain the necessary estimates of solution $(n,c,u)$ without the diffusion term $\Delta n$. These uniform estimates enable us to establish the global-in-time existence of almost weak solutions for the system.
