(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

纠结于B选项。看了很多帖子，大家排除b的原因除了逻辑意思是错的，主要集中在下面两点1.but 后面缺少主语 2."puts on , broadens and feigns "不对，应该用"puts on , broadens , and feigns "

对于1，我认为，but 后的主语因为是前面的snake, 可以省略，如Prep1-35，

In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, a substance that promotes blood clotting,
but does not seriously interfere with the production of prostacyclin, which prevents clotting.

对于2，我不清楚这种解释是否可以用来排除B，因为白勇的语法里“句子1，句子2 ，and 句子3” 和 “句子1，句子2 and 句子3” 都是正确的。所以不知道是不是V1,V2,and V3= V1, V2 and V3 .

如果这样，在没明白逻辑意思（并列问题）的情况下，只通过语法知识是不是不能排除B选项啊？不知道自己这样想对不。。。请教大家

对于B，很明显的一条，eventually是副词，不能加句子。C就可以

个人的一些看法，这个问题的答案牵涉很多别的条件，比如a,b,c本身的结构，句子外的结构等。就此题来说，A,B and C的结构等同于A,B,and C的结构，因为B and C之外没有更高层次的并列了，所以不存在b and c跳出a的逻辑层次和更高层次并列的问题，但是有些时候是有这样的问题的，比如：X1 do1 sth1 that do2 sth2, do3 sth3 and do4 sth4，此时后面的do3和do4到底是在定语从句之内还是跳出定语从句和do1并列就是有歧义的，所以就需要改为a,b,and c的结构。上题的B选项主要是but后面缺少主语，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；

几点个人看法：
(1)在这里puts on , broadens and feigns ＝ puts on , broadens , and feigns

(3)with的逻辑主语被省略了，感觉应该可以这样用。但我找不到例证，请NN来补充。

比如：X1 do1 sth1 that do2 sth2, do3 sth3 and do4 sth4，此时后面的do3和do4到底是在定语从句之内还是跳出定语从句和do1并列就是有歧义的，所以就需要改为a,b,and c的结构。

问1）那改成do3 sth3 ,and do sth4 后，是和2并列，还是和大层次1并列呢？

问2） But 后面虽然没有主语，但我认为是为避免重复snake而省掉的，句子结构是but with...,if..,(snake) will fall over.. 这样想可以吗？

以下是引用michelle77在2009/7/16 15:25:00的发言：

liu_leaf ，谢谢这么详细的讲解，但还有些不明白

问1）那改成do3 sth3 ,and do sth4 后，是和2并列，还是和大层次1并列呢？

问2） But 后面虽然没有主语，但我认为是为避免重复snake而省掉的，句子结构是but with...,if..,(snake) will fall over.. 这样想可以吗？

hehe ,可能有点钻牛角尖，不过还是希望NN解答下~

我也很想知道A,B,andC 是不是等于A,B and C.希望NN帮助。

20 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.
