[Grammar] Question about "ed" ending in some sentences?

[DnlaVP]

When I read some sentences, I become confused. I see some words in the sentences, which is end on "ed". Sometimes, I start thinking, that this is past simple tense. Sometimes, when I wrote some sentences, I write some words with the "ed" ending too. But I did it clearly intuitively (on a hunch).

For example (some of native speakers, who gave me reply for my question, he wrote):

Example: "I'm not surprised that you're confused." (Why we can't write without "ed", e.g. "I'm not surprise that you're confuse)

Another example: "But it's almost always included in English." (Why we can't write without "ed", e.g. But it's almost always include in English)

Another example: "It is always required when used this way." (Why we can't write without "ed", e.g. , It is always require when use this way)

Another example: "Present Perfect - a completed action without a SPECIFIC time in the past" (Why we can't write without "ed", e.g.Present Perfect - a complete action without.... )

Another example: "This time is not mentioned directly." (Why we can't write without "ed", e.g. This time is not mention directly)

As I have understood, this is not past simple tense. I did it in some sentences too, but I don't know, why? I did it on a hunch. I don't know how I should formulate the sentence for searching.

Could you explain me please, why we do this? What things I should know to understand, why we write sentences with "ed" ending?:-(

Kind regards.

I don't know what happened in the other forum, but I think you should learn about the "passive voice": http://www.writing.utoronto.ca/advice/style-and-editing/passive-voice
