Questions & Answers about qǐng jīhuó tā.
Yes—here 请 is being used to make the sentence polite, much like please in English.
So:
- 请激活它。 = Please activate it.
A useful thing to know is that 请 can also be a full verb in other contexts, meaning to invite or to request. But in this sentence, it is simply a politeness marker placed before the verb phrase.
Examples:
- 请坐。 = Please sit.
- 请看这里。 = Please look here.
Mandarin word order here follows the basic pattern:
- 请 + verb + object
So:
- 请 = please
- 激活 = activate
- 它 = it
That gives:
- 请激活它。 = Please activate it.
If you said 请它激活, that would suggest please let it activate... or ask it to activate..., which is a very different structure. In the original sentence, 它 is the thing being activated, so it comes after the verb as the object.
