解释: 本句的难度在GMAT文章当中可以说是最高的。很多人把这句话难以看懂的原因归结为专有名词太多,其实看看笔者在上面所作的标志就会知道,这句话难懂的真正原因还在于句子极其复杂的结构。

句首是一个表示被动的过去分词结构作状语。可是这个大状语中又有两个小状语,而且第一个小状语outside the nucleus又把Transported to拆开;主句当中又有两个状语,同样是第一个状语/into the protein (that it encodes)/把translated by分开。这个状语中省略了一个定语从句的引导词that 。从by之后到句末整个是一个长长的状语,长的原因,是在ribosome后面跟了一个结构复杂的非限定性定语从句。这个从句中照例又有两个状语,其中的第一个是倒装:which strings /together/ amino acids 的正常结构是which strings amino acids /together/。第二个状语中又是层层修饰,令人心烦意乱。整句十分难读,而最令人气愤的是,这个令考生花了很多时间来读的句子,后面居然没有出题。
