comma 之後個動詞點用?

Originally, it could be a complex sentence, written as:
... price reflects all publicly available information, which includes information such as accounting statements. ("which" refers to available information)

When converting the relative clause into a (participial) phrase, you drop the relative pronoun "which" and change the verb into its present participle form if it is in active voice, and past participle if passive voice.

So, which includes becomes including in the above sentence.

... price reflects all publicly available information, which is published on different leaflets.

So, which is published becomes published in the above sentence.

或者首先更正你對在這個位置的詞的誤解：
verb-ing這個是present participle
verb-ed這個是past participle

因此
簡而言，用法上沒有分別，即是排列在後面一些附加理解前面的東西...
當句子是present tense時便用present participle.
當句子是past tense時便用past participle.

我想你先掌握入門吧

She had many jobs for the last three years, included being waitress, real estate agent, driver and home decorator.
