172. 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
A: 两个动词之间应该有连词
B: 同上
C: correct
D: broadening 和 feigns不平行；but with no 不如用句子表达好
E: broadening 和feigning之间必须有连词
注意：
1、but with no这种介词结构在GMAT里，都倾向用完整的句子方式进行表达
2、目的状语并列必须用连词不能用逗号，以前考过
e选项中，broadening和feigning两个分词做状语，他们中间要有连词and吗？怎么没有听说过呢？
所有并列的结构之间都需要连词的。
我们听太多并列谓语了，常常忽略了状语，而PREP里不少这样的题目，并列的状语之间也必须有连词，否则第二个状语的修饰对象就不清楚。
