求助一道PREP，很有迷惑性

20.(25635-!-item-!-188;#058&002069)hissing and rearing和broadening and feigning都是分词作状语，并列！And连接两个长句子

注：我还是头一次见这样的分词修饰并列结构！

The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.

其主语为the hognose snake

我错选B，认为broadens and feigns和puts并列，but作为后面句子的连词

(A) broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom,

(B) broadens the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom,

(C) broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and

(D) broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and

(E) broadening the flesh behind its head the way a cobra does, feigning repeated strikes, but with no dangerous fangs and no venom, and

答案选C，我的问题是B中的but不能连接后面的部分吗？因为我认为with独立主格在这里可以当做插入语，忽略不计。请指教！

(B)首先， broadens…and feigns和hissing形式不对等; 其次，根据逻辑含义，but只用于转折前半句话The hognose snake puts on an impressive bluff的，因此除非but+V，要不but+句子，以表示与前句的转折平行；再看后面eventually是副词,不能连接两个句子,必须加上and 。而且这里的with+n并不是独立主格，就是个介短，这样with引导的状语缺乏修饰对象，另外当然逻辑意思很重要，第一个字句明显后面的动作都是bluff的进一步描述，把他们跟puts on并列逻辑上不对

(C) 正确, 使用伴随状语broadening…and feigning…作为伴随成分修饰主句,和hissing构成并列结构;用and连接两个句子,表达正确

这个with结构不是独立主格，独立主格一般都做状语，但是这个with 结构和后面的句子一点关系都没有，无法作状语修饰后面的任何成分
