Whenever we answered incorrectly,she pointed a long stick at us and ,shaking it up and down ,shouted,"NO,NO,NO!"
pointedshaking shouted 是不是并列动词 ?为何时态不同?

shaking it up and down用ing形式做伴随状语,表示一种与前面动作同时进行的状态
“她指着我们的同时还在晃动着脑袋”可以举几个例句么例如:   ①He sat in the armchair,reading a newspaper.   他坐在扶手椅里读报。   ②All night long he lay awake,thinking of the problem.   他整夜躺在床上睡不着,思考着那个问题。
