Discussion Overview
The discussion centers on the adequacy of the criteria for the present perfect tense as defined in John Warriner's textbook, "Warriner's English Grammar and Composition." Participants explore the definitions of the past tense and present perfect tense, questioning whether Warriner's criteria sufficiently encompass all usages of the present perfect tense, particularly in relation to modal verbs and specific examples.
Discussion Character
- Debate/contested
- Technical explanation
- Conceptual clarification
Main Points Raised
- Some participants argue that Warriner's definitions of the present perfect tense are inadequate, citing examples that do not fit the provided criteria but seem to require the present perfect tense.
- One participant states that "should have" is a modal verb construction and does not represent the present perfect tense, suggesting that "I should have written the research paper yesterday" is grammatically correct but not in the present perfect tense.
- Another participant questions the absence of modal verbs in Warriner's textbook, noting that it does not adequately cover this aspect of English grammar.
- Some participants express skepticism about the comprehensiveness of Warriner's textbook, suggesting it may not serve as a complete guide to grammar.
- There is a discussion about the implications of using relative terms like "yesterday" in the context of tense, with one participant arguing that it complicates the validity of examples.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the adequacy of Warriner's criteria for the present perfect tense. There are competing views regarding the definitions and examples provided, particularly concerning modal verbs and their relation to the present perfect tense.
Contextual Notes
