In the framework of the littlest Higgs(LH) model, we consider the processes e+e-→ννH0 and e+e-→ W*W*νν→ννtt, and calculate the contributions of new particles to the cross sections of these processes in the future high energy e+e- collider(ILC) with √(S)=1TeV. We find that, with reasonable values of the free parameters, the deviations of the cross sections for the processes e+e-→ννH0 from its SM value might be comparable to the future ILC measurement precision. The contributions of the light Higgs boson H0 to the process e+e-→ W*W*νν→ννtt are significant large in all of the parameter space preferred by the electroweak precision data, which might be detected in the future ILC experiments. However, the contributions of the new gauge bosons BH and ZH to this process are very small.
