Expressing Completed and Unfinished Actions
When we talk about actions, we sometimes need to show whether an action is finished or not finished. In English, we use special verb forms called tenses to do this. This lesson will teach you how to use:
- Present Perfect – to show completed actions at the present time
- Past Perfect – to show an action completed before another action in the past
- Present Perfect Continuous – to show an action that started in the past and is still happening now
We use the present perfect tense to talk about actions that have happened before now. The action is complete.
Structure
| Subject | has/have | Past Participle |
|---|---|---|
| I, You, We, They | have | verb-ed (or irregular form) |
| He, She, It | has | verb-ed (or irregular form) |
How to Form the Past Participle
- For regular verbs: add -ed (e.g., played, cleaned, watched)
- For irregular verbs: learn the special forms (e.g., have seen, have gone, have written)
Examples from the Textbook
Look at these sentences from the dialogue:
- "What has happened here?" (Police Officer asked)
- "I have seen Mashaka running away from my house with a bag."
- "We have seen Mashaka running with the bag."
- "You have made a mistake."
More Examples
Affirmative (positive) sentences:
- The boy has kicked the ball.
- The girl has finished the race.
- I have bought a good cow.
- The children have cleaned the cowshed.
- Upendo has taken the bag from the grandmother's house.
Negative sentences (add "not" after has/have):
- The boy has not held the ball.
- She has not finished her homework.
Questions (put has/have before the subject):
- Has the boy kicked the ball? Yes, he has.
- Have they climbed Mount Kilimanjaro?
We use the past perfect tense to show that one action was completed before another action in the past.
Structure
Subject + had + past participle
How to Use It
When we have two actions in the past, the action that happened first takes the past perfect. We often use the word "before" or "after" to connect them.
Examples from the Textbook
| Time | Action | Sentence |
|---|---|---|
| 10:05 am | James ate breakfast | |
| 12:10 pm | His father came home | James had eaten breakfast before his father came home. |
- The boy had cleaned the blackboard before the teacher wrote the word "English."
- James had milked the cow before he went to school.
- Mary had cleaned her room before her friend arrived.
Practice Sentences
Complete these sentences using the past perfect:
- The plane had left (leave) before I arrived at the airport.
- Naomi had finished (finish) writing before John cleaned the board.
- Baraka had left (leave) before I arrived.
- I had opened (open) the door before he entered the house.
Negative Form
To make negative, add "not" after "had":
- The Police Officer had not arrived when Mwaluko caught the thief.
- Mashaka had not finished eating when his father came home.
We use this tense when an action started in the past and is still happening now. The action is not finished.
Structure
Subject + has/have been + verb(-ing)
Key Words
We often use these time words:
- since – since 6 o'clock, since last month
- for – for 30 minutes, for a week
Examples from the Textbook
From the dialogue about Juma:
- "What has Juma been doing?"
- "Juma has been watering the garden."
- "He started at 6:00 pm, and now it is 6:30 pm."
From the conversation between Sadick and Anna:
- "I have been reading this book since last month."
- "I have been reading this book for a month."
From the story about Tausi:
- "She has been planting flowers since morning."
- "Her brother has been helping her."
- "They have been working hard."
How to Change Simple Sentences to Present Perfect Continuous
| Simple Present/Present Perfect | Present Perfect Continuous |
|---|---|
| Scola is writing her story. | Scola has been writing her story. |
| Juma and Musa are drawing pictures. | Juma and Musa have been drawing pictures. |
| She has watered the garden. | She has been watering the garden. |
| We have read the book. | We have been reading the book. |
| Tense | Use | Example |
|---|---|---|
| Present Perfect | Action completed at present | I have finished my homework. |
| Past Perfect | Action completed before another past action | I had finished my homework before he came. |
| Present Perfect Continuous | Action started in past, still happening | I have been doing my homework for an hour. |
- has/have – used in present perfect
- had – used in past perfect
- been – used in present perfect continuous
- since – shows when action started
- for – shows how long action has been happening
- before – shows one action happened earlier than another
In everyday life in Tanzania, you use these tenses without knowing it! For example:
- At the market, you might say: "I have been waiting for the dalali to lower the price of maize for thirty minutes." This shows you started waiting in the past and are still waiting now.
- When reporting something to a mwandishi: "The thief had entered the shop before the security guard arrived." This shows the order of events that happened in the past.
