标题: 请教og-47

OG 47
OG-47isplays of the aurora borealis, or"northern lights,"can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles,induce electric currents that can cause balckouts in some areas and corrosion in north-south pipelines.
A)to affect the trajectories of ballistic missiles,induce
B)that the trajectories of ballistic missiles are affected,induce
C)that it affects the trajectories of ballistic missiles,induces
D)that the trajectories of ballistic missiles are affected and induces
E)to affect the trajectories of ballistic missiles and induce

为什么这里面一定要用and,而不用逗号？有什么却别呢？我不认为如果不用逗号，induce就应该是变成分词做状语啊，我们不是常常看到三个动词连在一起，前两个用逗号隔开，第三个用and并列的句子么？莫非是说这也是一个规则？

induce做状语也得用分词形式，没见过动词原型直接作状语的。

句中只有两个动词，所以用AND连接，只有三个或三个以上时，A，B，AND C要用COMMA隔开，另AND表并列，分词表修饰或伴随，要根据句义判断。
