题目分析:
本题主要难度在于划线部分的后半段包括未划线部分会有很多词不认识,但是其实没关系,只需要知道这些词都是一些拟声词就可以了。
选项分析:
A选项:现在分词短语nevertheless creating sounds是伴随状语,但我们必须把这个伴随状语改成一个普通的合句。“海豚缺乏声带(Dolphins lack vocal cords)”和“海豚能创造声音(they do create sounds)”这两个动作之间没有强弱关系,是纯粹的两个转折句。因此,需要用并列连词连接。
B选项:分词短语nevertheless creating sounds是伴随状语错误同选项(A)。
C选项:Correct. 本选项在语法和逻辑上均是正确的。
D选项:a complicated system of whistles, squeaks, moans, trills, and clicks being produced sphincter muscles inside the blowhole是独立主格结构,还原为正常从句则有:
a complicated system of whistles, squeaks, moans, trills, and clicks was produced sphincter muscles inside the blowhole.
由于这句话是被动语态,所以其并未指明produce的主语是谁。在本题语境中,创造这些声音的肯定是海豚。如果没有指明是谁,则其无法和they do create sounds这句话形成任何关系。
E选项:nevertheless creating sounds错误同选项(A)。
是否需要用状语修饰,需要考虑两个句子间是否存在逻辑关系。
D,sounds作为system的先行词,不合逻辑,排除
