摘　　要：We construct dark energy models which have high derivative terms. In the framework of a single scalar field model with a higher derivative, the equation of state （EOS） ω might have some special character in the evolvement, which states that the universe will evolve in some interesting ways. We study the different kinds of dark energy models, and classify them into several genera by their character in the evolvement.We construct dark energy models which have high derivative terms.
