Объяснение:

"When she has dinner, she watches TV."

This sentence is describing a habitual action that occurs regularly. The subject of the sentence, "she," is someone who consistently watches TV while having dinner.

Now, let's break down the sentence and understand why the verb forms "has" and "watches" are used.

First, let's focus on the verb "have." In the given sentence, "have" is used in the third person singular form, which is "has." We use "has" instead of "have" because the subject of the sentence is "she," which is a singular pronoun. The third person singular form of the verb "have" is used when the subject is he, she, or it. For example, we say "he has," "she has," or "it has." In this case, the subject "she" is having dinner, so we use "has."

Next, let's analyze the verb "watch." In the given sentence, "watch" is used in the base form without any changes. We do not add an "s" or "es" to the verb because it follows the subject "she." When a subject is in the third person singular form (he, she, it), we do not add an "s" or "es" to the verb. For example, we say "he watches," "she watches," or "it watches." In this case, the subject "she" is watching TV, so we use "watches."

Remember, it is important to clarify that this sentence describes a habitual action, indicating that she watches TV every time she has dinner.
