1. While some propose to combat widespread illegal copying of computer programs by attempting to change people’s attitudes toward pirating, others by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling for the prosecution of those who copy software illegally.

(A) by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling

(B) by suggesting the reduction of software prices to decrease the incentive for pirating, and still others call

(C) suggest the reduction of software prices for decreasing the incentive for pirating, and still others call

(D) suggest the reduction of software prices to decrease the incentive for pirating, and still others by calling（E）

(E) suggest reducing software prices to decrease the incentive for pirating, and still others are calling

1.为什么E要用and still others are calling而不是用and still others call呢?

2.suggest doing是除了suggest that以外的另一种固定用法吗?

请NN解惑~谢谢

我不是NN

这里用propose...suggest...are calling  并没有破坏平行，这里用现在进行时

表示正在发生的并持续发生的动作。

suggest 表示提出一种可供选择的、推测性的建议，后接动名词。
