【日积月累】长难句每日练习【十四】

这个考研季强哥陪你过......今天的难句大家先自己做解析就在下一张图后面哦加油！29.Alownum...

29. 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+）

30. 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 that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research. （5）

31. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of　individual zooplankton species in the　laboratory and then computing community grazing rates for field conditions　using the known population density　of grazers. （5）



29. 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+）

在存在大量食草动物的同时却只有少量的水藻花粉囊，这暗示出——但没能证明——食草动物已吞噬了大部分水藻。

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.

30. 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 that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research. （5）

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（而这些浮游生物我们现在知道是捕食者主要的食物）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。

难句类型：复杂修饰、插入语

解释：句子的结构繁杂。句子的主语令人吃惊地长，在最后一个逗号后的led以前，全是主语！其实句子的主干简单，就是the fact led to a de-emphasis of the role of grazers。但是本句的主语the fact后面的修饰成分长得吓人，先是个定语从句；定语从句中又套了一个定语从句。然后逗号后面的a practice引导的部分是前面的主语的同位语兼任插入语，practice后面的修饰它的一大堆东西又是定语从句套着定语从句。本句是典型的层层修饰结构。

意群训练：Perhaps the fact that 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 that we now know grazers are most likely to feed on, led to a de-emphasis of the role of grazers in subsequent research.

31. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of　individual zooplankton species in the　laboratory and then computing community grazing rates for field conditions　using the known population density　of grazers. （5）

由哈格雷夫（Hargrave）和吉恩（Geen）所进行的研究，对自然条件下的群落捕食速率进行了估计，其手段是通过测量出实验室内单独的浮游动物种类的捕食速率，然后利用已知的食草动物种群密度，计算出实地状况下的群落捕食速率。

难句类型：复杂修饰

解释：本句对阅读者的阅读能力提出了更高的要求，不但要求读者读清楚句子的复杂的结构，而且对读者的词汇能力也提出了更高的要求。

By以前结构无需解释，by以后有两个作介词宾语短语的动名词结构，measuring和后面表示并列和顺接的and then之后的computing，说的是计算方法；前一个measuring说的是先算出实验室中浮游动物品种的单位捕食速率，后面的computing前其实省略了一个by，而且在这个动名词结构中还包括一个分词结构using the known population density of grazers，用已知的捕食者的种群密度计算出其野外的群体捕食速率。整个的by以后的计算过程简单了就是：实验室单位速率×野外密度＝野外群体速率

另外本句中的词汇也颇有迷惑性；虽然没有太难的单词，但是很多单词都是同义词和反义词，容易让人读混；（斜线分隔同义词，冒号分隔反义词）

estimate/measure/compute; feeding rates/grazing rates; zooplankton/grazers; natureal/field; laboratory community; individual

意群训练：Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of　individual zooplankton species in the　laboratory and then computing community grazing rates for field conditions　using the known population density　of grazers.
