难句类型:插入语
解释:本句主语很长,而且谓语suggested与that引导的宾语从句间被插入语but did not prove隔开,造成阅读障碍。当suggest与but did not prove连在一起使用的时候,其意思不是建议,而是指一种基于主观臆测的推理,中文翻译成暗示。其英文释义为:to call to mind by though or association the explosion suggested sabotage。GRE、GMAT及LSAT文章中,常用suggest,but do not prove来描述一种没有真凭实据、可能有问题的理论,然后在后面的叙述中把它否定掉。
意群训练:A low number of algal cells in the presence of a high number of grazers suggested,but did not prove, that the grazers had removed most of the algae.
3. Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net , a practice that overlooked the smaller phytoplankton that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research.
可能这样一个事实,那就是很多这样的最初的研究只是考虑了那些能够用网捞起来的大小的水藻,这样一个忽视了更小的浮游生物的做法,导致了在接下来的研究中对于捕食者的作用的贬低。
