BRIEF SCIENCE JUSTIFICATION: (restrict yourself to 1-2 paragraphs)

Besides the dwarf novae with short orbital period CVs, Nova-like
variables including SW Sex-type CVs with high accretion rates and
Intermediate polars with long orbital periods are also critical to
unravel CV formation and evolution. The parameters of CVs located on
the high edge of the period gap are especially important for tests of
the current standard evolution theory of CVs. Although some of them
have been studied before, many newfound CVs with orbital periods
between 3~4 hr lack investigations. This means that updated analyses
for them are necessary. We expect to do high time resolution
photometry for the bright targets. After literature searches, we found
that there are over 200 CVs with magnitudes less than 18 on the upper
edge of the period gap. And many objects are available from May to
October. Moreover, among these, the eclipsing systems comprise nearly
30 percent. By modeling the complete light curves, their basic
physical and geometric parameters could be constrained. Additionally,
we also expect to detect many more transient events in Nova-like stars
since the permanent outburst state may result in more valuable
phenomena.
