Aulease -- if you want to pass this class, you must follow your instructor's directions. If you post your questions on this board, you'll get additional help by heeding the advice we give.
Subject-verb agreement:
To determine whether to use "have" or "has," you need to consider the subject of the sentence. "Have" is used with plural subjects, and "has" is used with singular subjects. For example, "They have three dogs" (plural subject) and "She has a cat" (singular subject).
Regular and irregular verbs:
To determine whether to use regular or irregular verbs, you need to familiarize yourself with the conjugation patterns of common verbs. Regular verbs follow a consistent pattern when forming their past tense or past participle forms, while irregular verbs do not. For example, "become" is an irregular verb, and its past tense form is "became." "Take" is a regular verb, and its past tense form is "took." "Lay" is an irregular verb, and its past tense form is "laid."
Correct form of "be" and "have" in the present tense:
The correct form of "be" and "have" in the present tense depends on the subject of the sentence. Use "am" with the pronouns "I" and "we" (e.g., "I am happy," "We am going"). Use "is" with the pronouns "he," "she," "it," or a singular noun (e.g., "She is singing," "The dog is barking"). Use "are" with the pronouns "you," "they," or plural nouns (e.g., "You are funny," "The cars are fast").
Verb form and verb tense:
To determine whether to use "have" or "appeared" and "built" or "have," it depends on the context and the tense of the sentence. "Have" is the base form of the verb, while "had" is the past tense. "Appeared" is the past tense of "appear," and "built" is the past tense of "build." Consider the timing of the action being described in the sentence to make the correct choice.
Identifying antecedents:
To identify the antecedent of a pronoun, look for the noun or pronoun that the pronoun replaces. For example, if you have the sentence "The students are studying. They are working hard," the antecedent of "they" is "students." Similarly, if you have the sentence "The doctors are treating their patients," the antecedent of "their" is "doctors."
Pronoun antecedent agreement:
To ensure pronoun antecedent agreement, the pronoun must agree with its antecedent in number, gender, and person. For example, if the antecedent is singular and feminine, the pronoun should be "she" or "her." If the antecedent is plural and gender-neutral, the pronoun should be "they" or "them."
Pronoun case:
To determine whether to use "me" or "I," "she" or "her," you need to consider the role of the pronoun in the sentence and whether it functions as the subject or object. "I" is used as the subject, and "me" is used as the object. Similarly, "she" is used as the subject, and "her" is used as the object.
Pronoun case for "who" and "whom":
To determine whether to use "who" or "whom," you need to distinguish between the subject (who) and the object (whom) of the sentence. "Who" is used when referring to the subject, and "whom" is used when referring to the object. For example, "Who is going to the party?" (subject) and "Whom did you invite?" (object).
Vague pronouns:
To avoid vague pronouns, ensure that the pronoun clearly refers to a specific noun or noun phrase. In the sentence "When the car hit a tree, it crashed into a tree," the pronoun "it" is vague because it is not clear what it refers to. To make it clear, you could say, "When the car hit a tree, the car crashed into it."
Vague pronoun:
Regarding the example sentence "This increasing pollution is a big problem for many cities," it is vague because it does not specify what "this" refers to. To make it clear, you could say, "The increasing pollution is a big problem for many cities."
