关于同位语 that 可以省略吗,请看一个句子
Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net (net phytoplankton),a practice that overlooked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on ,led to a de-emphasis of the role of grazers in subsequent research.
perhaps that fact 后面是省略了that吗,这个that是同位语的引导词吗,不是不可以省略的吗

Answer 1

这不是同位语,这是个定语从句,many of these first studies作为the fact的定语,在定语从句中,被修饰词充当宾语时,that是可以省略的
