Getting stressed with grammar tenses

Hi everyone

I am having some difficulty with my grammar and would really appreciate it if someone could check/correct my answers to the following questions;

Identitfy the form in the following sentences:

1) The plane leaves at 10:00 tomorrow.

2) If i had a lot of money, i'd buy a boat.

3) You should go to the doctor.

4) I'll kill you!

5) I've just had lunch.

6) By the time i got there, the bus had left.

Answers

1) Present simple + time marker

Verb 'to leave' in the present tense + time marker

2) present (2nd) conditional

'If' + past perfect; would + infinitive of verb buy, without 'to'

If clause + past perfect of verb 'to have' ; auxiliary verb + main verb

3) Not really sure what the tense is here!

Auxiliary verb 'should' + main verb 'go' without 'to'

4) Future simple

Auxiliary verb 'will' + main verb 'to kill' without 'to'

5) Present perfect simple

Subject + verb 'to have' (not sure about the rest)

6) Not sure again waht the tense is here

i can only work out the second part which i think is 'past perfect' Simple past of auxiliary verb 'have' + past participle of verb 'leave'

Kind regards
