Third Person Singular in Present Perfect
The video begins by reviewing the third-person singular form of the present perfect tense. The structure is: Person (he, she, it) + "has" (conjugated form of "have") + Past Participle + Complement.
- Example 1: "She has danced since 2020." Here, "she" is the person, "has" is the auxiliary verb, "danced" is the past participle, and "since 2020" is the complement.
- Example 2: "He has talked with me." "He" is the person, "has" is the auxiliary verb, "talked" is the past participle, and "with me" is the complement.
- Example 3: "It has jumped the fence." "It" is the person, "has" is the auxiliary verb, "jumped" is the past participle, and "the fence" is the complement.
The video emphasizes the importance of understanding regular and irregular verbs when forming the past participle. Regular verbs form the past participle by adding "-ed," similar to the simple past tense. Irregular verbs have varying past participle forms that must be memorized.
First Person Singular and Plural, Second Person Singular and Plural, and Third Person Plural in Present Perfect
The video then transitions to the use of "have" with other pronouns (I, you, we, they). The structure remains the same: Person + "have" + Past Participle + Complement.
- Example 1: "I have worked since 2020." "I" is the person, "have" is the auxiliary verb, "worked" is the past participle, and "since 2020" is the complement.
- Example 2: "We have eaten." "We" is the person, "have" is the auxiliary verb, and "eaten" is the past participle (irregular verb).
The video provides examples of irregular past participles:
- "Eaten" (past participle of "eat")
- "Been" (past participle of "be")
- "Had" (past participle of "have")
The video concludes by reminding students to "take care" and "see you".
