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.

(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

考点:句子结构（Grammatical Construction）平行对称（Parallelism）

1)副词不能当作连词使用

2)并列结构中最后一个并列成分应该用and连接,如果只有两个并列成分,则只能用and等连词连

接

3)并列结构中,每个并列成分要概念对等,形式平行

(A) broadens和hissing, feigning形式不对等,并且feigning前面必须加上and; eventually是副词,

不能连接两个句子,必须加上and.

(B) broadens…and feigns和hissing形式不对等; eventually是副词,不能连接两个句子,必须加上

and

(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

(D) broadening和feigns不平行

(E) feigning前面必须有连词and连接,不能用逗号连接

疑问：关于C答案，题中应该是 hissing and rearing back， broadening the flesh behind its head the way a cobra does   和   feigning repeated strikes 三个部分并列，为什么and feigning 前面不加上逗号呢？

小天River

结构会不会是A and B，C and D，but E？而且E是和最开始的puts 平行，所以要用一般现在时的第三人称单数。。。

kyle7

C答案中but作为连词又引导了另外一句完整的话～

小天River

是啊 it 指代 hognose snake，but之后的句子和主句平行 也就是puts和has平行。那两个and结构 是 impressive bluff 的同位语吧？作解释说明。。。
