Yes, it is still wrong, and it is not passive voice. The passive version of your first example would be:

(1) "The box containing the paper was opened by me".

Most passives require the verb "be" + past participle, as in (1), but your second example is active, not passive since there is no verb "be" present. It is also ungrammatical because in the active voice, "box" requires either a present participial clause or a relative clause:

(2) "I opened the box containing the paper".
(3) "I opened the box which contained the paper".

In (2) and (3) the underlined clauses are modifying "box". The first is present-participial clause, and the second a relative clause.

Jason, may I ask you a question? Are you a native speaker of English, or are you learning it as a second or foreign language?

Thanks Paul. I am an ESL student . I am trying to understand when to use present participle and past participle as an adjective phrase to describe a noun.

Example 1: Employees are required to follow the protocols outlined in this manual.
I believe "outlined in this manual" is a past participle phrase?

Example 2: Employees are required to follow the protocols, outlining in this manual.
I believe "outlining in this manual" is a present participle phrase?


After reading your comment, I would rewrite the sentence:

Example 3: Employees are required to follow the protocols which outlined in this manual.

Example 4: Employees are required to follow the protocols, outlining in this manual.

Are those correct? If so, what is the difference?

PM: Yes, this is correct, but it's a clause, not a phrase.


PM: No, this is incorrect. It should be a past participle verb, not a present participle one. Your Example 1 is correct.


PM: No, they are both wrong:

Example 3 should be: "Employees are required to follow the protocols which are outlined in this manual".

And example 4 is the same as example 2. which is wrong for the reason I gave.
