However, almost all regular verbs have not been used in the past. So the auxiliary verb is used, z.B. you helped, not you helped. Lattner, S., and Friederici, A. D. (2003). The voice and gender stereotype of the spokesperson in the treatment of acoustic recrimination – evidence of the brain potential associated with the event. Neurosci. Lett. 339, 191-194. doi: 10.1016/S0304-3940 (03)00027-2 All regular (and almost all irregular) verbs in English agree in the singular third person of this indicator by adding a suffix of -s or – it.
The latter is usually used according to the stems that end in the sibilants sh, ch, ss or zz (z.B. it rushes, it hides, it collects, it buzzes.) There is a verb-subject chord as in your first sentence. The vast majority of French verbs use having as tools and do not correspond to their subjects as do the verbs of “Tre”. However, they require the agreement of any previous direct purpose. A. (1998). Subject predicate agreement in Hebrew: links with semantic processes. Long. Mr. Cogn.
Trial. 13, 575-597. doi: 10.1080/0169099998386447 You have seen that in compound times, such as The Compound Past, the majority of verbs used as a tool. See z.B. Conjugate regular -er verbs (to have) in The Compound Past (Past of Conversation). For these verbs, the old participation remains unchanged. The same goes for verbs used as tools in The Compound Past. as conjugation come and go verbs (to be) in The Compound Past (past conversation), Conjugate die, beneo, die, become, remain (to be) in The Past (past of the compound conversation) and Conjuggate reflexive verbs (`being`) in The Compound Past (Past Conversation). At the beginning of modern times, there was an agreement for the second person, which singularus all the verbs in the current form, as well as in the past some usual verbs. It was usually in the shape-east, but -st and t also occurred.
Note that this does not affect endings for other people and numbers. As with the verbs of Being, all conjugations of passive voices require a match with the subject. The chord or concord (in abbreviated agr) occurs when a word changes shape according to the other words to which it refers.  This is a case of bending and usually involves making the value of a grammatical category (such as sex or person) “agree” between different words or parts of the sentence. Osterhout, L., Bersick, M. and McLaughlin, J. (1997). Brain potentials reflect lesions of gender stereotypes. Mr. Cogn. 25, 273-285. doi: 10.3758/BF03211283 In standard English, you can say I am or it is, but not “I am” or “it is”.
This is because the grammar of the language requires that the verb and its subject coincide personally. The pronouns I and him are respectively the first and third person, just as the verbs are and are. The verbage form must be chosen in such a way as to have the same person as the subject, unlike the fictitious agreement based on meaning.   In American English, for example, the expression of the United Nations is treated as singular for the purposes of concordance, although it is formally plural. The word “agreement,” if one refers to a grammatical rule, means that the words used by an author must be aligned with number and sex (if any). For more details on the two main types of agreements, please see below: Object-Verb-Accord and Noun Pronoun. The very irregular verb is the only verb with more coherence than this one in the contemporary form.
