In both sentences, the verb corresponds to its subject, the box. Don`t be fooled by the prepositional sentence of the second sentence and think that ornaments are the subject. This is simply the object of the preposition of and does not affect the concordance of the subject and the verb. This sentence has more than one subject or compound subject: computer, film and television. Although all verbs follow the same principle of agreement, some verbs seem a little more problematic than others. In particular, many conformity errors result from the abuse of the usual verbs have, make and be. Sometimes nouns take on strange shapes and can make us think that they are plural when they are really singular and vice versa. See the section on plural forms of names and the section on collective names for additional help. Words like glasses, pants, pliers, and scissors are considered plural (and require plural verbs), unless the pair of sentences is preceded by them (in this case, the pair of words becomes subject).
Two singular nouns or pronouns, separated by either. Or not. Don`t take a singular verb. The verb of a sentence must correspond in number and person to the simple subject of the sentence. The number refers to the question of whether a word is singular (child, account, city, I) or plural (children, accounts, cities, us). The person refers to the question of whether the word refers to a spokesperson (I am the first person), the person to whom we are talking (you are the second person) or what we are talking about (he, she, she, she; Gary, the university, taxes are a third person). The subject-verb agreement means that a subject and its verb must be both singular and pluralistic: if your sentence unites a positive subject and a negative subject and a plural, the other is singular, the verb must correspond to the positive subject. Indefinite pronouns SubjectsAn indefinite pronoun is always singular, and some are always plural.
(Some can go both ways; for more information about indeterminate pronouns, check out the tip Sheets pronouns and reference pronouns or in an author`s manual like SF Writer.) Third person Choosing SingularVerben to match the themes of the first and second person is usually not a major problem, but a peculiarity of the singulate obscedity of the third person causes in some students, especially ESL students, some confusion in the work with the singular subjects of the third person. Sometimes modifiers will find themselves between a subject and its verb, but these modifiers should not confuse the match between the subject and its verb. Some indefinite pronouns are particularly annoying Everyone (even listed above) certainly feels like more than one person and therefore students are sometimes tempted to use a bural with them. But they are always singular. Each is often followed by a prepositional sentence that ends with a plural word (each of the cars), which disrupts the choice of verb….
