Present Perfect / Infinitive

[Emanuelli]

Please, let me know if the following sentences are correct.

a) Have you already taken a shower? / Have you taken a shower yet? (what's the difference?).
b) Have you already found a job? / Have you found a job yet?

c) The next question is about the use of the verbs in the infinitive form (to).
Example: Aim: To hold students' attention. Is it possible to leave "to"out and say: "Hold students'attention? I've read some books and I don't understand why some of them use (to) and why the others don't.

d) Hold this for a moment, will you? (Is my tag question right?)

Thanks.

Thanks.

a) b) I believe there's a slight difference between 'already' and yet':
'Have you already had a shower? (the speaker's asking if it has actually happened)
'Have you had a shower yet?' (the speaker is expecting it to happen)
But 'yet' is mainly used in negative sentences.

c) To hold students' attention = (in order) to hold students' attention...cause-effect situation. If you drop it out, this would become an imperative situation.

d) 'will you' is OK.

This is what I think..but I'm not a 100% reliable source!

a) Have you already taken a shower? / Have you taken a shower yet? (what's the difference?).
b) Have you already found a job? / Have you found a job yet?
With 'yet', I'm asking a question where I really don't know. If I put 'already' in, I could be surprised at the fact that I think they may have done it.

c) The next question is about the use of the verbs in the infinitive form (to).
Example: Aim: To hold students' attention. Is it possible to leave "to"out and say: "Hold students'attention? I've read some books and I don't understand why some of them use (to) and why the others don't.
Do you mean after the word 'aim'? If so, yes. If not, then I'd leave the 'to' in.

d) Hold this for a moment, will you? (Is my tag question right?)
