Lesson 5: Connect past and present

Use present perfect when the past matters inside the present frame.

~45 MINUTES · PERFECT ASPECT

Reference point is now

Present perfect uses have/has + past participle. It looks backward from now: present result, life experience, change until now, or a period that still includes now.

I lost my key yesterday. finished time

I have lost my key. present result: no key now

I worked here for five years. finished employment

I have worked here for five years. continues now

Finished time blocks the frame

Do not combine present perfect with a finished past time such as yesterday, in 2022, or last week: I saw her yesterday, not I have seen her yesterday. An unfinished frame works: I have seen her twice this week when this week continues.

Simple versus continuous perfect

I have written three reports. focuses result or count. I have been writing reports all morning. focuses duration or activity, perhaps unfinished. Some state verbs prefer simple: I have known her for years.

Four-contrast drill

Create pairs for present result, life experience, unfinished duration, and recent activity with visible evidence. Add one finished-time version to every pair.

Controlled practice

  1. Choose: “I saw / have seen her yesterday.”
  2. Choose: “I worked / have worked here since 2023” if still employed.
  3. Contrast “She wrote three reports” and “She has written three reports.”
  4. Contrast result and duration with simple/continuous perfect.
  5. Use for and since correctly.
  6. Use already, yet, still, just in natural positions.
  7. Correct: “I am here since Monday.”
  8. Explain when “this week” can take past simple or present perfect.
Check controlled answers
  1. I saw her yesterday.
  2. I have worked here since 2023.
  3. Past simple locates finished event; perfect connects result/count to now.
  4. Have written focuses result; have been writing focuses activity/duration.
  5. For + duration; since + starting point.
  6. Position varies by item and focus; verify examples.
  7. I have been here since Monday.
  8. Perfect if week continues; past if speaker frames relevant period as finished.

Shortcut that works

Look for reference point, not word “past.” If now contains result or unfinished period, present perfect becomes available; finished-time adverb usually closes it.
