Before and After: Connecting Past Events
In this lesson, you can join two past events with before and after.

Try the activities, then check your answers.
Choose a short recording.
Before you start
Name two things you did yesterday in order.
See one possible response
I bought a ticket. Then I joined the queue.
You describe a short day trip and explain how your group coordinated arrival and tickets.
What you will practise
- Join two past events with before and after.
- Change sentence order without changing the story.
- Keep clear who did each action.
Answer first. Then check one model. Keep the meaning and the target pattern.
Two complete clauses
Before or after can connect two clauses, each with its own subject and verb. I checked the route before we left. The people checking and leaving can be different. In this lesson, ordinary past-simple clauses give the sequence clearly.
I packed the tickets before we left.
We ate after the guide arrived.

The order on the page can change
A time clause can come first or last. After the guide arrived, we ate means the same sequence as We ate after the guide arrived. Moving the clause does not change the meaning of after. In writing, a comma usually follows an initial time clause.
Before the bus arrived, Maya bought water.
Maya bought water before the bus arrived.
Keep both people clear
Name a new subject when the actor changes. I left after Sam called has two actors. Do not remove Sam and assume every action belongs to I. Before and after already express order; do not add unnecessary tense changes just to make the sentence longer.
The driver waited before we boarded.
After I paid, the assistant gave me the tickets.
Two clauses can have two different actors
The time clause names the customer.
The main clause names the assistant.

Guided practice
Say or write your answer first. Then compare the meaning and grammar with the model.
1. We checked the map. Then we walked to the station. Use before.
Compare a model and explanation
We checked the map before we walked to the station.
Checking comes first.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
2. The rain stopped. Then they went outside. Use after.
Compare a model and explanation
They went outside after the rain stopped.
Going outside follows the rain stopping.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
3. We sat down after the host arrived. Start with After.
Compare a model and explanation
After the host arrived, we sat down.
The same event order remains.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
4. Before Eva arrived, Tom made tea. Who acted first?
Compare a model and explanation
Tom made tea first.
Before Eva arrived places the tea-making earlier.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
5. You ate first and called later. Repair I ate after I called.
Compare a model and explanation
I ate before I called.
Before restores the supplied order.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
6. After I opened the door, Nina carried the box inside. Who carried the box?
Compare a model and explanation
Nina.
The second clause explicitly names her.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
7. After the class finished we cleaned the room.
Compare a model and explanation
After the class finished, we cleaned the room.
A comma normally follows the initial time clause.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
8. Lee arrived at ten; you showed the room at ten five; the group sat down at ten ten. Use two linked sentences.
Compare a model and explanation
After Lee arrived, I showed him the room. The group sat down after I showed it to him.
Preserve order and name the different actors.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
A short conversation
Listen to the exchange, then take one role. The speaker labels identify roles; do not narrate them.
Open the conversation transcript
Traveller: Did you buy the tickets before the bus arrived?
Friend: Yes. I bought them after the office opened.
Traveller: Good. What did you do next?
Friend: After I bought them, I called you.

Compare all choices
- After the host arrived, we ate.: Only clause position changes.
- We arrived after the host ate.: This changes both actions and participants.

Complete a full clause: before ___.
the bus arrived: It contains a subject and a past verb.
Compare all choices
- the arrived bus we: The words do not form the intended clause.

- bus arrive to: This is not a complete past clause.
After I paid, the assistant gave me the receipt. Who paid?
The speaker.: I is the subject of paid.

The rain stopped first; we left later. Choose the accurate sentence.
We left after the rain stopped.: This preserves the sequence.
Compare all choices

- We left before the rain stopped.: This reverses it.
- The rain stopped after we left.: This also reverses it.
Choose the usual written punctuation.
Before the talk began, we found our seats.: The initial time clause is followed by a comma.
Compare all choices
- Before the talk, began we found our seats.: The comma splits the clause internally.
- Before the talk began, we found our seats.: The initial time clause is followed by a comma.
- Before, the talk began we found our seats.: The comma separates before from its clause.
Does moving an after clause to the start automatically reverse the event order?
No.: After keeps the same temporal relationship.
Compare all choices
- Yes, always.: Position alone does not reverse its meaning.
- Only when the verb is regular.: Verb regularity is irrelevant.
- No.: After keeps the same temporal relationship.
Choose the sentence preserving different actors: Sam called first; I left later.
I left after Sam called.: Both actors and the sequence remain explicit.
Compare all choices
- I left after Sam called.: Both actors and the sequence remain explicit.
- Sam left after I called.: Both roles have changed.

Use it in your own words
Two past events
Connect two ordinary events with before, then express the same order with after.
Reveal a possible response
I locked the door before I left. I left after I locked the door.
- Preserve the event order
- Use full clauses
Other real or invented events are fine.
Different people
Describe two linked actions by different people.
Reveal a possible response
After my friend arrived, I made tea.
- Name both actors
- Keep the chronology clear
Use a different pair of people if preferred.
Put it all together
Explain a small problem during a day trip and how people solved it. Use before and after, at least two actors, and one time expression from an earlier lesson.
Reveal a possible response
The bus arrived ten minutes late. Before we boarded, the driver checked our tickets. After we sat down, my friend called the museum. We arrived half an hour later.
- Use both connectors
- Keep actors distinct
- Retrieve a relative time phrase
The situation is fictional; a different coherent sequence is acceptable.
Take it with you
Use complete clauses after before and after. Changing clause order does not reverse the time relationship. Keep different actors explicit.
