most striking among the many asymmetries evident in an adult flatfish is eye placement:before maturity one eye migrates,so that in an adult flatfish both eyes are on the same side of the head. (3+)

在一條成年比目魚身上顯著存在的諸多不對(duì)稱(asymmetry)特征中,最為吸人注目的是眼睛的擺位:在成年之前,一只眼睛發(fā)生移動(dòng),因此在成年比目魚身上,兩只眼睛均位于頭部的同一側(cè)面。

難句類型

倒裝、省略

解釋:

本句的倒裝本質(zhì)上與我們?cè)缇偷囊环N倒裝結(jié)構(gòu)是一樣的,即形容詞放在句首時(shí),主語和謂語倒裝。本句的主干的正常語序應(yīng)該是:eye placement is most striking;倒裝后成了most striking is eye placement。但是這種倒裝在gre考試中出現(xiàn),又有了新的特色,被提到句首的most striking被長長的狀語among the many asymmetries evident in an adult flatfish與后面的主語和表語分開,造成閱讀困難。

意群訓(xùn)練
