This type of error is called error of agreement. Each normal sentence has a subject (in this case Mary) and a verb (like). The form of the verb depends on who or what the subject is. First of all, you have to ask yourself whether the theme is singular or plural: not all verbs follow a predictable pattern. These verbs are called irregular verbs. Some of the most common irregular verbs are, have and do. Learn the forms of these verbs in contemporary form to avoid errors in the subject-verb chord. In this case, if you can identify the list as the object of the sentence, then it will be easy for you to choose the singular «is» as a verb. Previous sentences refer to unspecified pronouns. In these cases, it is good to remember that everyone, everyone, no one, no one and no one is always considered singular and that they must be accompanied by singular verbs. It is always tempting to think that everyone is a plural theme. However, it refers to the singulars, because it refers to each person in a crowd. So it`s unique.
On the other hand, indeterminate pronouns like all, or some may be either singular or plural. These are verbs that are used to display certain actions. In most cases, they are applied when they discuss what someone is doing or to show actions. For example, do, walk, run the reader The trick to agree your subject and the verb is to identify the amount of your subject and the verb corresponding to it. However, there are sentences that are not easy to calculate. For example, this rule can sometimes be difficult, especially when it comes to more topics, as it can lead to unpleasant phrases. In these sentences, the verb remains the singular of the second person and the second in the plural. In the singular form, the pronoun refers to a person. In plural form, the pronoun you refer to a group of people, such as a team.B. The basic rule in the convention of reference is that a singular subject takes a singular verb and a plural subject a plural verb.
The use of these conventions is important for good English writing. In the academic letter, the neglect of verbal agreements has serious consequences. This means that your message is not being conveyed, that your readers are confused and that your credibility is diminished.
