the notion that interspecific hybrids are rare is ill-founded .
有一种看法认为种间杂种是罕见的,这种看法是无根据的。
the left has insisted on a government-run insurance scheme, but this ill-founded idea is strongly opposed by the health-care industry and by republicans.
左派支持政府操作保险计划,但是这个毫无根据的提议去而遭到了医疗业和共和党人的反对。
i think that these are all the same question, founded on the same implicit but ill-founded assumption: that risk equates to danger.
