Today’s central idea: Tense locates a viewpoint in time. Aspect shows how the speaker chooses to view the situation from that point: as a whole, as unfolding, as prior and relevant, or as prior activity with duration. At C1, accuracy includes choosing the view that serves the message.
Retrieval bridge
Say each answer before revealing it. The goal is to reactivate language that today’s lesson will extend.
Connect to what you already know
Contrast a completed result with an activity still in progress: write the report / since Monday.
I’ve written the report shows a completed result. I’ve been writing the report since Monday foregrounds the continuing activity.
Look back from a past deadline: the team / test the system / for six weeks.
The team had been testing the system for six weeks before the deadline.
Project completion forward from now: by next Friday / we / interview / all candidates.
By next Friday, we will have interviewed all the candidates.
Notice before the rule
One project, three viewpoints
A program director updates a funding partner. The dates are the same, but each verb choice directs attention differently.
We launched the mentoring program in 2021, and we have supported more than 600 participants since then.
We have been tracking long-term outcomes for the past eighteen months, so the evidence is becoming more reliable.
By next June, we will have been running the program for ten years.
Which verb presents a finished event at a finished past time?
Which perfect form foregrounds a result that matters now, and which foregrounds an activity developing through time?
Why does the final sentence use a future perfect progressive rather than a simple future form?
Noticing check
Why does the director say “have been tracking” rather than “tracked”?

Speaker’s choice
Use it when…
Example
simple
you present a situation as a whole, a fact, a completed event, or a repeated pattern
She consults for several nonprofits.
progressive
you foreground an unfolding, temporary, changing, or limited situation
She is consulting for a health nonprofit this year.
perfect
you connect an earlier situation to a later viewpoint through result, experience, or sequence
She has advised the organization on three major projects.
perfect progressive
you connect earlier activity to a later viewpoint while foregrounding duration, repetition, or evidence
She has been advising the organization since January.
Sound natural: Auxiliaries are usually reduced in fluent speech: “we’ve been TRACKing,” “they’d already LEFT,” and “we’ll have FINished.” Stress the information that updates the timeline. Keep an auxiliary strong only when correcting or contrasting: “I HAVE finished it.”

A delayed research partnership
Read the project lead’s account. Notice how each tense choice organizes evidence around now, an earlier meeting, and a future deadline.
Our university began discussing the partnership last fall. By the time the two teams met in February, we had already exchanged three draft agreements and had been negotiating data access for four months.
Since that meeting, both sides have revised their security procedures. We have been testing the new system with a small group, and the initial results are encouraging.
The full study starts in September. By then, the technical team will have completed the migration, and the researchers will have been working together for almost a year.

Reusable practice routes
Choose today’s practice set
Choose the set that fits today’s learner. Each set contains different examples.
Core: Secure the central form-and-meaning decisions before increasing the pressure.
The laboratory started the trial in January. It is still collecting data. Which update fits both facts?
The audit is tomorrow. All twelve departments are already finished. Which sentence foregrounds the completed result?
A director explains a temporary arrangement for this quarter, not her permanent role. Which sentence is most precise?
At 4:00 yesterday, the analysts discovered the cause. Their investigation had started at 9:00. Which sentence highlights the earlier duration?
Contrast: Use the reading context to distinguish nearby meanings and prevent overgeneralization.
Which completed activity happened before the February meeting?
Why is “have been testing” appropriate in the second paragraph?
What will be complete by September?
Why does the account use “will have been working” for the researchers?
Challenge: Apply the same system to less predictable contexts without repeating the Core examples.
The program’s tenth anniversary is next June. Which sentence measures the activity up to that future point?
A consultant normally works in Boston but is spending six weeks in Denver. Which sentence frames the Denver role as temporary?
The team finished four reports, and the exact completed quantity matters now. Which update is most precise?
At the time of the merger, negotiations had continued for eight months. Which form foregrounds that earlier duration?
Core set selected.
Build the future duration
Measure the program’s duration from its next anniversary.
Diagnose and repair
Find the precise problem. A useful correction includes the reason, not only the repaired sentence.
Connect the starting point to now
I work here since the office opened.
View completion from the deadline
By Friday, we complete the final interviews.
Show the earlier duration
When the report arrived, they reviewed the data for three weeks.
Separate a finished result from an unfinished process
We have been completing all twelve interviews, so the task is finished.
Fluency drill
Respond aloud first. Reveal the model only after you have committed to an answer; your wording can differ if the meaning and form are right.
Transform and expand
Your organization started a project two years ago. It continues now. Give one result and one continuing process.
We have reached 2,000 users, and we have been improving the service for two years.
Look back from a past turning point. Explain what had finished and what had been continuing.
By the time the policy changed, we had completed the pilot and had been collecting feedback for six months.
Look forward to a deadline. State one completed result and one measured duration.
By December, we will have opened three offices and will have been operating in the region for five years.
Correct yourself aloud after choosing an aspect that hides the meaning you need.
We have been finishing six reports. More precisely, we have finished six reports, so the completed quantity is the point.

A year of evening tutoring
Read once for meaning. Then read again and do the tasks below.
Coordinator’s update254 wordsAbout 2 min
When the Riverside Library launched its evening tutoring program last September, we expected about thirty adult learners, most of them looking for help with job applications or English for work. By the time the first term ended in December, we had registered ninety-two, and volunteers had been working two extra shifts a week to keep up. Maria Chen, who had been teaching English in Lima before she moved here, offered to lead a second group.
Since January, we have recruited fourteen new tutors and opened a second room on Thursdays. We have been testing a short placement interview for new learners, and the early results are encouraging: fewer people are changing groups after the first month. Attendance at the Thursday sessions has grown steadily since February.
Not everything has gone smoothly. Several tutors have been asking for more training in teaching writing, and some learners have been waiting for a place since March. Their names are on a list, and we contact them as soon as a seat opens. We are currently looking for a third room, ideally one with space for small-group work.
Our partner college is designing a workshop for tutors, which will take place in October and will focus on giving clear feedback on writing. We will share the dates in our next update. By the end of next year, we will have trained every volunteer, and the program will have been running for more than two years. Thank you to everyone who has given an evening to make this happen.

The timeline briefing
Give a two-minute briefing on a real project, career change, research task, or long-term goal. Move from its origin to the present and then to a future milestone. Your listener should be able to reconstruct the timeline without seeing your notes.
Role 1Speaker: establish three reference points, distinguish results from processes, and make at least one deliberate contrast between two possible aspect choices.
Role 2Listener: draw the timeline, ask what was complete or still developing at each point, and request clarification if a verb choice creates an unclear sequence.

Our team began redesigning the service last September. By the time the board approved the budget in January, we had interviewed forty users and had been testing two early prototypes for three months. Since approval, we have completed the core design, and we have been refining the booking process with a smaller user group. The evidence is becoming more reliable, although we have not resolved every accessibility issue. By October, we will have launched the new service in three regions, and the research team will have been tracking user behavior for a full year.
Reflect and transfer
Can you do this without the page?
Choose simple, progressive, perfect, and perfect progressive forms for a communicative reason.
Maintain a clear timeline across several reference points.
Explain how a different aspect choice would change the listener’s interpretation.
Your next use: Record a ninety-second update about a long-term project. Listen again and identify the viewpoint and aspect purpose of every verb phrase. Return to the retrieval bridge next lesson.
