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


答案(c)
我想問一下大家,三個以上的東西平衡,句意上是不是不能出現轉折
可以說:N1,N2,N3 but N4嗎　
還是一定要說N1,N2, and N3 but N4

另外(d)(e)中後面...,but with no dangerous fangs...可以這樣用嗎
還是一定要跟(c)一樣再but後面再補出主詞動詞it has..

[hey]

puts on為主要句子的動詞1,broadening則為動詞2, 其由and broadens而來, 去掉and且動詞broadens改為分詞前再加逗號, 動詞3則為feigns, 因為用and連接, 因此feigns必需與前面的broadening平衡, 所以變為feigning, but為連接詞, 其之後為另一句主要子句, 主詞為it, 動詞則為has.... and will fall, if為附屬子句, 如將完整的主要子句改為with....,則主要子句會沒有主詞, 所以只能選(C), 而(D), (E)不能選
