The correct form is When did I come? (I did come when).
Yes, that is correct. But there should not be an article("a") before "correct".
The correct sentence is "She didn't come." "Come" is the past participle of the verb "to come," so it should be used with the auxiliary verb "do" in the negative form as in this sentence.
The correct sentence is 'I will come home at 3pm'.
The answer is C.(3) He should never have come here.
'Did she came...' is incorrect. 'Did she come...' is correct.
The correct phrase is "Here I am." The verb "am" should come before the subject "I" in this particular sentence structure.
No, the sentence should be "He elucidated his position on this matter by his silence." The verb "elucidated" should come before the subject "he" to create a grammatically correct sentence.
Yes, the sentence is correct. The implied subject of the sentence is you."You come...""You enter..."
No this is incorrect grammar. To make the sentence grammatically correct you should say: One of my cousins came yesterday.
The correct grammar for this sentence is: When did your friend come?
it should read "With diversity comes tolerance and compassion"
