This lesson covers the perfect tenses and the main ways of talking about the future, from will and going to to the present continuous for arrangements. It shows how each structure places an event in time.
B1 expands the future well beyond will and going to. English has at least six ways of talking about what has not yet happened, and each carries a different shade of meaning about certainty, planning and timing. Choosing among them is what separates intermediate English from elementary English.
Alongside the future, B1 adds the present perfect continuous — have been plus -ing — which emphasises the duration or the ongoing nature of an activity rather than its completion. I have written three reports counts results; I have been writing reports all morning describes the activity itself.
The most useful new form is the future perfect and future continuous pair. By next June I will have finished the course locates a completion point in the future; This time tomorrow I will be flying to Madrid locates an activity in progress. Both let you position events relative to a future moment rather than simply to now.
How to form Perfect and Future Tenses
| Form | Structure | Meaning | Example |
|---|---|---|---|
| will | will + base verb | prediction, decision now | I'll call you later. |
| going to | be going to + base | plan, evidence-based prediction | We're going to move house. |
| present continuous | be + -ing | fixed arrangement | I'm meeting her at six. |
| present simple | base verb (+s) | timetable | The train leaves at nine. |
| future continuous | will be + -ing | in progress at a future time | I'll be working at ten. |
| future perfect | will have + participle | completed before a future time | I'll have finished by Friday. |
| present perfect continuous | have been + -ing | duration of a recent activity | I've been studying all day. |
Perfect and Future Tenses: the key rules
-
The present perfect links past to present; the past perfect steps one layer further back — the past of the past.
When we arrived, the film had already started.
-
English has no single future tense — it recruits will (predictions, decisions), going to (plans, evidence) and the present continuous (fixed arrangements).
I'm meeting Lena at six — we're going to discuss the move. It'll be fine.
-
The present simple covers timetables and schedules.
The train leaves at 7:40.
-
After time conjunctions (when, until, as soon as, before), the future hides in the present simple.
I'll call you as soon as I land.
When to use Perfect and Future Tenses
-
Positioning an event before a future deadline
The future perfect is the only form that does this cleanly, and it usually appears with by.
By the end of the month we will have completed the migration.
-
Describing an activity in progress in the future
The future continuous, often with this time tomorrow or at ten o'clock.
This time next week I'll be lying on a beach.
-
Emphasising duration rather than result
The present perfect continuous focuses on how long the activity has been going on.
I've been waiting for over an hour.
-
Softening a question about plans
The future continuous can ask about arrangements without sounding like a request.
Will you be using the car tonight?
Present perfect simple vs. continuous
The simple form counts completed results; the continuous form measures the activity. Many sentences accept both, with a genuine change of emphasis.
Present perfect simple — result
How much, how many, how often. The action is complete and the outcome matters.
I've read three chapters. She has written four emails.
Present perfect continuous — duration
How long. The activity may still be going on, and its effects are visible now.
I've been reading all afternoon. She's been writing emails since nine.

Common mistakes (and how to fix them)
-
When I arrived, the meeting started. (meaning it began before I got there)
When I arrived, the meeting had started.
To show one past event happened before another, the earlier one needs the past perfect.
-
I'll text you when I will arrive.
I'll text you when I arrive.
Will cannot follow a time conjunction — the present simple carries the future there.
-

Perfect and Future Tenses: frequently asked questions
When do I use the future perfect rather than will?
Use the future perfect when you are looking back from a future point at something already completed. By next Friday I will have submitted the application places the completion before that deadline. Plain will simply predicts: I will submit the application on Friday. The future perfect almost always appears with by, by the time, or before plus a future reference.
What is the real difference between I've worked and I've been working?
The simple form emphasises the completed result or quantity, while the continuous emphasises the duration and often implies the activity is still going on or has just stopped with visible effects. I've painted the kitchen means the job is done; I've been painting the kitchen explains why you are covered in paint. With state verbs only the simple form is possible.
How many future forms do I really need?
For B1 purposes, four cover almost everything: will for predictions and instant decisions, going to for plans and evidence-based predictions, the present continuous for fixed arrangements, and the present simple for timetables. The future continuous and future perfect are worth learning because they appear in exams and in professional English, but they are less frequent in ordinary conversation.
Can I use the present perfect continuous with state verbs?
No, for the same reason state verbs avoid every continuous form. I have been knowing him for years is wrong; the correct form is I have known him for years. This catches learners out precisely because the meaning — a situation continuing over time — feels like it should demand the continuous. With know, believe, own, like and the other statives, always use the simple perfect.
