Units 9-10: Present Perfect Continuous vs Simple — English Grammar in Use
Discover the Present Perfect Continuous tense and learn to distinguish it from the Present Perfect Simple.
1. Introduction
Building on our knowledge of the Present Perfect, Units 9 and 10 introduce the Present Perfect Continuous and compare it directly with the Present Perfect Simple. These units are critical for expressing how long something has been happening versus how much has been accomplished, giving you the tools to speak with greater precision.
2. Unit 9: Present Perfect Continuous (I have been doing)
Grammar Rule
The Present Perfect Continuous focuses on the activity itself and how long it has been going on. We use it for an activity that has recently stopped or just stopped, where there is a clear physical connection to now. Or, we use it for an activity that began in the past and is still going on now. It also measures duration using the time markers for and since.
- We form the Present Perfect Continuous using have/has been followed by the -ing form of the verb.
- Use for + a period of time (e.g., for two hours).
- Use since + a starting point in time (e.g., since Monday).
Form Table
| Subject | Positive | Negative | Question |
|---|---|---|---|
| I / We / You / They | have been working | have not been working | Have you been working? |
| He / She / It | has been working | has not been working | Has he been working? |
Key Examples
Positive
- Paul is very tired. He has been working very hard.
- It has been raining for two hours.
- We have been standing here since noon.
Negative
- I haven’t been feeling well lately.
- She hasn’t been sleeping much recently.
- They haven’t been practicing the piano.
Question
- You’re out of breath. Have you been running?
- How long have you been learning English?
- What have you been doing all morning?
When to Use

3. Unit 10: Present Perfect Continuous vs Simple
Grammar Rule
Unit 10 focuses on the vital distinction between the Continuous form and the Simple form.
- Present Perfect Continuous emphasizes the activity and duration (How long?). The activity might be unfinished.
- Present Perfect Simple emphasizes the completed result or achievement (How much? How many? How many times?). The activity is finished.
Remember that State Verbs (like know, like, believe) cannot be used in continuous tenses.
Form Table
| Feature | Present Perfect Continuous | Present Perfect Simple |
|---|---|---|
| Focus | The activity itself | The result / completion |
| Key Question | How long? | How much/many times? |
| Example | I have been reading the book. | I have read the book. |
Key Examples
Positive
- My hands are dirty. I have been repairing the bike. (Continuous)
- The bike is fixed now. I have repaired it. (Simple)
- She has been playing tennis since she was 8. (Continuous)
- She has played tennis three times this week. (Simple)
Negative
- I haven’t been working much. (Continuous)
- I haven’t finished my work. (Simple)
- He hasn’t been feeling well. (Continuous)
Question
- How long have you been reading? (Continuous)
- How many pages have you read? (Simple)
When to Use
| Situation | Example |
|---|---|
| Focus is on the activity (whether finished or not) | I have been writing emails all morning. |
| Focus is on the completed achievement | I have written ten emails this morning. |

Comparison
- Continuous: It has been raining for two hours. (We are interested in the activity of rain)
- Simple State Verb: I have known about it for a long time. (Not have been knowing. State verbs MUST use the Simple tense, even for duration.)
📝 Quick Summary
Unit 9:
- Use the Present Perfect Continuous for an activity that has recently stopped or is still going on, with an emphasis on the activity itself.
- Don’t forget: Use since for a starting point and for for a length of time, to explain exactly how long an activity has been happening.
Unit 10:
- Use the Continuous tense for the activity itself (How long?); use the Simple tense for the result (How much/How many amounts?).
- Don’t forget: State verbs (e.g., know, believe) must use Present Perfect Simple, never Continuous.
