Before you begin this lesson, you need to understand what a topic is. Each complete sentence has a subject (person or thing) and a verb (action). The subject is the person or thing that makes the action in a sentence. Whether you`re writing or talking, it`s important to use the verb form that matches the theme of a sentence. This is called the verb-subject agreement. In contemporary form, for example, singular nouns and plural nouns need a different form of verb. Contractions can throw people away when it comes to a verb-subject chord, so let`s break one of them. That`s all you need to know about this lesson, but if you want to learn more, you can attend Lesson 1 of Module 5. Keep in mind that the subject verb chord is usually only in periods that use the present, such as the simple present, to present perfectly, and present progressive. This is because the present has two forms, whereas most other periods have only one. Let`s compare the simple times of the present and the past. Kelly is the subject. He`s the one with the driver`s license.
You can see that the execution has two forms that are present, but only a form of the past. It`s the same for most other verbs. Sandra is the subject. That`s the person who ran the race. You`ve probably noticed in the meantime that the verb that`s supposed to be is often the exception to the rule, and this case is no different. It`s the only verb that has two past forms, so you have to be especially careful.
