1) For a singular third person (he/she) in the present tense, the verb must have an extension of -s: some languages do not use a verb in some sentences: for example, Russian rarely uses the verb “to be” in the present tense. Chinese languages seem to have adjectives that act as verbs. It`s worth being aware of how your language differs from English. Verbs are words of action. For example: eating, sleeping, talking, walking, doing, buying are all verbs. In your example, the verb was influenced by the singular “a firefighter”: this is, I suppose, a “native speaker error”, although I`m not sure what an examiner would think if the BBC could. However, for some quantity sentences, you must refer to the name of the prepositional sentence to decide whether the verb is singular or plural: therefore, if we create sentences, we must think about the type of subject we have in terms of person and number to be able to choose the appropriate verb. For example, when you were a beginner student and you studied the verb – you learned that you had to use the following forms with the different subjects: in each of these examples, you only have to look at the first noun to decide whether the theme is singular or plural – you can ignore them afterwards. The parking lot (subsequent singular) was full (verb).
The parking spaces (plural subject) were full (verb). The verb in an or, or, or, or not, or ni/or sentence corresponds to the noun or pronoun closest to it. Another common mistake is when the subject is separated from the verb by a prepositional sentence, a relative set, or a relatively small set. I suspected that this is a team that includes a firefighter and a sedative. The verb must therefore have a singular form. Subject concordance simply means that the subject and verb must match in number. This means that both must be singular or both plural. Well, it all sounds a bit chic, but in fact, you learned it at the beginner level and have been using it ever since (even if you didn`t know it, 🤣). Here is a table with the different subject pronouns in English, divided by person (to whom we talk /on) and number (how many people we talk/about): Modal verbs are always followed by the infinitive, so that in this case, the third person singular no longer takes a singular verb: confusing, isn`t it? And this is just one example of subjects that look plural, but are actually singular. As we will see in a moment, there are many others! In these sentences, each of the verbs corresponds to its subject. Therefore, you need to look at this word to decide whether the verb is singular or plural.
In English, sentence subjects are either SINGULAR (= UN) or PLURAL (= MORE THAN ONE), which also affects the type of verb you need in a sentence. Well, in many cases, it`s very easy to tell if the theme of your sentence is singular or plural. For example, I don`t think any of you would have a hard time choosing the right verb form for these sentences: Well, problems come with topics that aren`t obviously singular or plural. 🤔 So if you started a sentence — children — although children are followed by what they have, our verb must be singular! The fact that each sentence must have a verb and that the verb corresponds to the subject is the simplest part. However, when it comes to the subject-compliment agreement, it can sometimes get quite confusing, as is the case in the following sentence; When young people start earning money after school, they can afford their own home or start a family. The other question is whether “the team” takes a singular or plural message. As the graph shows, both are possible, with the singular being more common, especially in the United States. A topic will come before a sentence that will begin with. Exercise: The expressions in the first column are subject, and the expressions in the second column are verbs plus objects or prepositional sentences. . . .
