Be + past participle

Question

I have 3 related questions, so I've searched on the internet about this structure but I haven't got any answers. What is the meaning of Be + past participle, as in "be done", "be claimed" etc.?

I was trying to create a zero conditional sentence.

"I will come, when my base upgrades are done properly."

Was that grammatically correct? But I thought it would be better if I put "be done" in the sentence, which will be like this:

"I will come, when my base be upgraded properly."

Which one is correct?. As that is the first question, the second is:

How the Be + Past participle works?

The third question is, are there any words that describe the condition of a thing already upgraded? Since "upgraded" is a verb, it cannot be used as an adjective. Are there any synonyms of it?.

Answer 1

What is the meaning of Be + past participle, as in "be done", "be claimed" etc.?

The Past Participle is the 'ed' or 'en' form of a verb, and it denotes past tense.

The forms of 'be' are as follows -

Infinitive           to be
Present              am, is, are
Past                 was, were
Present Participle   being
Past Participle      been
Present Subjunctive  be
Past Subjunctive     were
Imperative           be

So, the past participle of 'be' is been.

Question #1

Was that grammatically correct? But I thought it would be better if I put "be done" in the sentence, which will be like this:

The first sentence is correct, and in the second, you will have to use the Present from of 'be', which is 'is', the same way that you have done in the first sentence.

So the second sentence should be -

"I will come, when my base is upgraded properly."

Question #2

How the does the Be + Past participle works work?

Please use the table given above.

Question #3

The third question is, are there any words that describe the condition of a thing already upgraded? Since "upgraded" is a verb, it cannot be used as an adjective. Are there any synonyms of for it?

Upgraded is an adjective. Upgrade is a verb. Upgraded is the past-participle of upgrade, and this makes it also. So upgraded can be used as a verb as-well-as an adjective.

For example, Verb form of upgraded -

I upgraded the water tank. It can now hold more than 2 litres of water

Adjective form of upgraded -

All of these machines are upgraded computers

Answer 2

Short answer:

Be + past participle = passive voice

For more information you can search the net for explanations. One option is here

---

"I will come, when my base upgrades are done properly."

It is correct.

---

"I will come, when my base be upgraded properly."

It is incorrect, "to be" is used wrongly in infinitive form. And you changed order of words, it makes no sense. In that sentence, "base" is just an adjective for "upgrades".

are there any words that describe the condition of a thing already upgraded? Since "upgraded" is a verb, it cannot be used as an adjective

No, there is no substitute for "is already upgraded", as far as I know.

"Upgraded" is a form of a verb (in this situation, past participle). In your examples, it is not used as an adjective, but as a past participle, as part of the passive voice.

However, in a different context, "upgraded" can be used as an adjective, as in:
