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

E选项为什么用are calling，而不用call？

从句子意群：尽管有人propose应该这样（改变态度），有人suggestion应该那样（降价减低利润），并且仍然还有人在做一件事情（起诉）。

while some....(负面策略), others suggest...（正面的让步策略）+ still others are doing...（正面的主动策略）

从语法上are calling & call都正确吧。个人意见。

这个问题我也曾经挣扎过很久. 仅凭一个for doing就把一个看似非常平行的C否定了.

这里的进行时应该不用的不是问题, 解题要有顺序, 是否进行时应该不是判断的第一步.

内容上的平行重要于形式上的平行.

ETS有很多平行都不是形式上的平行的.比如那个 密歇根真菌那题,就是 过去分词和现

在分词平行.

好像还有过不定式和现在分词平行(记不清了,反正是严重违背形式上的平行的).

这题我也错了,但是错的不是对于are calling的怀疑,而是错在 对for decreasing的考

点不敏感,还有对 suggest doing是否正确吃不准.

我看are calling吃不准的情况下,用排除发比较好.
