How to use past tense and past participle How to use past tense and past participle

Past tense: The simple past tense means something that happened at a specific time in the past, or it can also mean a habitual and regular action in the past. Generally, the impact of actions is not emphasized, only things are explained. Sentence structure: subject, past tense of verb, object, others. Past participle: 1. Use as a predicative. 2. The past participle used as an attributive is equivalent to an adjective. The past participle of a transitive verb is used as an attributive, indicating both passiveness and completion; the past participle of an intransitive verb is used as an attributive, indicating completion only. 3. As an adverbial, the past participle is used as an adverbial to express passive and completed actions.

Example: 　　Ihada word with Julia this morning. This morning, I said a few words to Julia. Hesmokedmanycigarettesadayuntilhegaveup. When he didn't quit smoking, he smoked very hard. The past tense is often used with adverbials or clauses expressing past time, such as: yesterday, lastweek, inthepast, in1993, atthattime, once, duringthewar, before, afewdaysago, when, etc.

Four rules for changing past participles: (1) For general verbs, add "-ed" directly to the end of the word. (However, it should be noted that the past participle is not the past tense) work---worked---worked, visit---visited---visited (2) Verbs ending with a silent "e" are only at the end of the word Add "d". live---lived---lived

(3) For verbs ending with "consonant letter y", change "y" to "i" and add "-ed". study—studied—studied, cry—cried—cried, try—tried—tried, fry—fried—fried. (4) Stress the end of a closed syllable, with only one consonant at the end (except r, y, x, w), double first Write the consonant letter and add "-ed". stop—stopped—stopped, drop—dropped—dropped
