Transcript
Unit 24: PRESENT PERFECT — FORMATION We use the present tense of the auxiliary verb have (Unit 17) before the past participle form (Unit 14). In the simple formation, the participle is the lexical verb (Unit 3); in the continuous formation, the participle is been, with the –ing form of the lexical verb after it. 1 Simple (have + past participle) a STATEMENTS EXAMPLES: He has worked very hard this term. The meeting has not started yet. I have rented a car for two weeks. They haven’t fixed the car yet. b QUESTIONS EXAMPLES: Have you finished yet? What has she decided to do? Why have they left? NOTICE: For spelling problems with the –ing form of the verb, look at Appendix 6. 2 Continuous (have been –ing form) a STATEMENTS EXAMPLES: I have been learning English for four years. He has not been feeling very well lately. It’s been raining non-stop for days. b QUESTIONS EXAMPLES: Have you been working hard recently? What’s she been doing? Why has it been raining so much? 3 Notes on past participles a Many verbs do not have an –ed participle (Appendices 10 and 11). b Have can be an AUXILIARY and a LEXICAL verb (Unit 3). EXAMPLES: Have the girls had lunch yet? We have been having a good time. c Go has two past participles EXAMPLES: He has gone to Rome. He has been to Rome. NOTICE: Unit 25 tells you about the use of present perfect. [not here now] [went and returned]
