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. (5)

可能這樣一個(gè)事實(shí)，那就是很多這樣的最初的研究只是考慮了那些能夠用網(wǎng)撈起來的大小的水藻，這樣一個(gè)忽視了更小的浮游生物(而這些浮游生物我們現(xiàn)在知道是捕食者主要的食物)的做法，導(dǎo)致了在接下來的研究中對(duì)于捕食者的作用的貶低。

難句類型：

復(fù)雜修飾、插入語

解釋：

句子的結(jié)構(gòu)繁雜。句子的主語令人吃驚地長(zhǎng)，在最后一個(gè)逗號(hào)后的led以前，全是主語!其實(shí)句子的主干簡(jiǎn)單，就是the fact led to a de-emphasis of the role of grazers.但是本句的主語the fact后面的修飾成分長(zhǎng)得嚇人，先是個(gè)定語從句;定語從句中又套了一個(gè)定語從句。然后逗號(hào)后面的a practice引導(dǎo)的部分是前面的主語的同位語兼任插入語，practice后面的修飾它的一大堆東西又是定語從句套著定語從句。本句是典型的層層修飾結(jié)構(gòu)。

意群訓(xùn)練：

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 pratice 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.
