Present perfect simple and past simple

💡 A stated finished time such as last June requires the past simple.

💡 The form rule is subject + have/has + past participle.

💡 Never goes between has and the past participle to describe no experience up to now.

💡 Just goes between have/has and the past participle.

💡 These adverbs express life experience, absence of experience, recent completion or expected completion.

💡 A specific detail at the finished time last weekend takes the past simple.

💡 Already normally comes between has and the past participle.

💡 Begin with present perfect for experience, then use past simple for a dated detail.

💡 Never already supplies negative meaning, so the no-double-negative rule applies.

💡 A present perfect experience question begins with Have before the subject.

💡 Yet normally goes at the end of a present-perfect negative.

💡 Present perfect covers unspecified experience and current relevance; past simple gives a dated detail.

💡 Yet at the end calls for a present-perfect negative; the requested contracted form is hasn't finished.

💡 Sentence-final position is the rule taught for yet.

💡 Write is irregular: wrote is past simple, but written is the past participle.

💡 Just goes after have and before the past participle.

💡 An experience with no known or important exact time uses the present perfect.

💡 Been to describes a visit followed by a return; gone to normally suggests the person is still away.

💡 The central tense contrast reserves present perfect for unspecified or unimportant time.

💡 After has, use the irregular past participle taken rather than the past simple took.
