Explanations:In English grammar, verbs are used to describe actions, occurrences, or states of being. Verbs can change their form to indicate different tenses, which help to specify when the action took place. The question at hand involves the past tense of the verb "visit," which is an irregular verb. Irregular verbs do not follow the standard pattern of adding "-ed" to form the past tense; instead, they have unique forms that must be memorized.
The sentence "He _____ his grandmother last weekend" requires the past tense form of the verb "visit" because the action took place in the past, specifically "last weekend." The correct past tense form of "visit" is "visited." Therefore, the correct sentence is "He visited his grandmother last weekend."
It is important to understand the difference between regular and irregular verbs. Regular verbs form their past tense by adding "-ed" to the base form. For example, the past tense of "walk" is "walked." However, irregular verbs do not follow this pattern. Some common irregular verbs include "go" (past tense: "went"), "eat" (past tense: "ate"), and "run" (past tense: "ran").
When constructing sentences in the past tense, it is crucial to use the correct form of the verb. Using the present tense form in a sentence that requires the past tense can lead to grammatical errors. For example, "He visits his grandmother last weekend" is incorrect because "visits" is the present tense form, and the sentence is referring to an action that occurred in the past.
Additionally, it is important to avoid double negatives in sentences. A double negative occurs when two negative words are used in the same sentence, which can make the sentence confusing or incorrect. For example, "He didn't visited his grandmother last weekend" is incorrect because it uses both "didn't" and "visited," which is a double negative. The correct form would be "He didn't visit his grandmother last weekend."
In summary, the correct answer to the question is "visited" because it is the past tense form of the irregular verb "visit," and it fits the context of the sentence, which refers to an action that occurred in the past. Understanding the correct forms of irregular verbs and the rules for forming the past tense is essential for constructing grammatically correct sentences in English.
