'When did I come' is correct. In this sentence, the verb 'come' should be in its base form 'come' after the auxiliary verb 'did'.
The correct answer is "come." "Came" is the past tense of "come," while "come" is the base form of the verb.
The correct form is "Did he come today?" The auxiliary verb "did" is followed by the base form of the main verb "come" in questions in the past simple tense.
The correct form is "had come." "Come" is the past participle form of the verb "come" and is used after "had" to indicate an action that occurred before a certain point in the past. "Came" is the simple past form of the verb "come" and cannot be used after "had" in this context.
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 form is "have they ever come." "Come" is the past participle form of the verb "come," and should be used with auxiliary verbs like "have."
"It didn't come in" is correct. The verb "come" is irregular, so the past tense is "came." Combining "did" with the base form "come" creates the correct negative past tense form.
"It didn't come up" is correct. The verb "come" should be in the base form after "didn't."
The correct verb form would be "begun."
"She didn't come" is the correct way of saying this. You could say "She never came" or "She didn't want to come" or "It was her fault she didn't come and nothing to do with me" or "It doesn't matter whether she came or not" After a form of 'to do' you always say the infinite vrom of the verb
