In the first place, professionals have voiced on various appropriate paramount incidents, matching outlooks to that of inflating the price of the plastic bags.

本句，有几个地方需要斟酌、修改：

1. voice 是及物动词，需要宾语。改为：voiced their opinions/views 。

2. appropriate 不知所云，删去。

3. 用 paramount 去修饰 incidents，属于“大材小用”。这么重要的词语paramount 去形容小事件？应把incidents 改为events 或issues。

4. matching...to...用词不当。表达某种观点与另一种观点相一致，是客观的，不能是人为地 “去配对；去匹配”，应改为：（which are） consistent with the view of inflating the price of the plastic bags.

全句修改如下：

In the first place, professionals have voiced their opinions/views on various paramount events/issues, （which are） consistent with the view of inflating the price of the plastic bags.

首先，专业人士就各种重大问题发表了自己的看法，（这些看法）与抬高塑料袋价格的看法是一致的。
