13. GWD31-Q13

Dolphins lack vocal cords, nevertheless creating sounds: a complicated system of whistles, Squeaks, moans, trills, and clicks are produced by sphincter muscles inside the blowhole

 

1)     nevertheless creating sounds: a complicated system of whistles, squeaks,        

moans, trills, and clicks are produced by

2)     [h1] nevertheless creating sounds: they produce a complicated system of whistles,

squeaks, moans, trills, and clicks with

3）but they do create sounds, producing a complicated system of whistles, squeaks, moans, trills, and clicks with [h2] 

4）but they do create sounds, a complicated system of whistles, squeaks, moans, trills, and clicks being produced[h3] 

5）but nevertheless creating sounds: a complicated system of whistles, squeaks, moans, trills, and clicks produced by

[h4] 

---

 [h1]are错；冒號後方大多出現名詞或名詞片語作補充用,若形成子句應該用分號.

 [h2]they do create sounds 的語氣是較強烈。

By +n. 施动者。

BY用来描述一个行为的细节,比如I TOOK THE KNIFE BY TACKING ITS BLADE.

WITH用来强调工具.比如I TOOK THE KNIFE WITH MY HAND.

with修饰的是produce,

with也有可能修饰它紧跟的词.解释前面的名词。

 Unlike humans, dolphins lack vocal cords, but they do use a complicated system of whistles, squeaks, moans, trills and clicks produced by sphincter muscles within the blow hole.

分词短语无逻辑主语，又不是伴随结果。错。

 [h3]Being多余。缺介词。

 

 [h4]应该对。

nevertheless=but，however，可以是副词，也可以是连词.

冒号有个功能，就是解释前面的内容。

5）还是3）？

觉得是3)

5)but nevertheless creating sounds错，but是连词，要跟句子，即使理解成主语省略也不对，GMAT有一类错误是but doing……
