Worksheets for practicing time conjunctions in context.

Problem Description:

The task involves filling in the blanks of a story titled "Emma's Journey" using appropriate time conjunctions: when, before, until, after, while. The goal is to make the sentences logically coherent and grammatically correct.

Story Text:

```
Everything seemed OK ______ Emma arrived at the train station to find out her train was late.
______ she had waited on the platform for a long time, the train finally arrived.
______ the train doors opened, lots and lots of passengers rushed off to start their busy day.
Emma waited for the rush to people pass her ______ she boarded herself.
Eventually, she was able to get on the train. She put her bags down ______ the train began to move away from the station.
```

Solution:

We will analyze each blank and choose the most suitable time conjunction based on the context.

1. Everything seemed OK ______ Emma arrived at the train station to find out her train was late.
- This sentence describes a situation that occurred before Emma arrived at the station. The word before fits here because it indicates the state of things prior to her arrival.
- Answer: before

2. ______ she had waited on the platform for a long time, the train finally arrived.
- This sentence describes an event that happened after Emma had waited for a long time. The word after fits here because it connects the waiting period to the arrival of the train.
- Answer: after

3. ______ the train doors opened, lots and lots of passengers rushed off to start their busy day.
- This sentence describes an action that occurred when the train doors opened. The word when fits here because it indicates the exact moment the doors opened, triggering the rush of passengers.
- Answer: when

4. Emma waited for the rush to people pass her ______ she boarded herself.
- This sentence describes an action that Emma performed until the rush of passengers passed. The word until fits here because it indicates that she waited up to the point when the rush ended.
- Answer: until

5. Eventually, she was able to get on the train. She put her bags down ______ the train began to move away from the station.
- This sentence describes an action that Emma performed while the train was beginning to move. The word while fits here because it indicates simultaneous actions (putting her bags down and the train moving).
- Answer: while
