How to Write a Past Story from a Given Sentence - B1 English Writing — Explanation

How to Write a Past Story from a Given Sentence

In many B1 English writing tasks, you are given the first sentence of a story and asked to continue it. The opening line is not only a title or an idea: it must be the exact beginning of your narrative. A successful answer connects naturally to that sentence, develops one clear problem, and finishes with a satisfying ending.

Writing task example

Use this sentence to begin your story: “As soon as Mia opened the old notebook, a photograph fell onto the floor.”

Model B1 story

As soon as Mia opened the old notebook, a photograph fell onto the floor. She had found the notebook in a box while she was helping her grandfather clear his attic. The photograph showed two children standing beside a huge oak tree, and one of them looked exactly like her grandfather. Curious, Mia turned the picture over. On the back, someone had written, “The secret is still under the roots.”

Mia asked her grandfather about the message, but he only smiled and said that she would understand soon. Later that afternoon, they walked to the park where the old oak tree still stood. While her grandfather was watching from a bench, Mia searched around its roots. After a few minutes, her hand touched a small metal box that had been buried beneath the leaves.

Excited, she opened it and found a toy train, three coins and a letter. Her grandfather explained that he and his sister had hidden the box fifty years earlier, before she moved abroad. He had believed that it was lost forever. If Mia had not discovered the notebook, they would never have found it.

That evening, they called his sister and showed her the objects on a video call. Surprised and delighted, she began telling stories that Mia had never heard before. Mia had expected to find an ordinary family photograph, but instead she uncovered a piece of her family’s history.

1. Build your story from the opening line

Read the given sentence carefully before you plan. Identify the person, place, object or event that must appear in your story. Ask yourself three simple questions:

• What happened immediately before or after this sentence?
• What problem, surprise or discovery could develop?
• How will the situation change by the final paragraph?

Do not replace the opening sentence or add a different introduction before it. Continue directly from it. In the model, the photograph creates a mystery, the message leads Mia to the tree, and the box provides a logical ending.

2. Plan a clear beginning, middle and ending

Beginning

Introduce the setting and connect the supplied sentence to the main event. Give only the background information that readers need. One or two details are usually enough.

Middle

Develop a problem, journey, misunderstanding or discovery. This is where tension should grow. Use actions and reactions rather than explaining everything at once.

Ending

Resolve the main situation. You can include a surprise, but it must make sense with the clues already in the story. A final sentence can show what the character learned, felt or discovered.

3. Use narrative tenses accurately

A B1 story normally combines several past tenses. Each tense has a different job.

Past simple for the main events

Use the past simple for completed actions that move the story forward in chronological order.

• Mia turned the photograph over.
• They walked to the park and found the tree.
• She opened the box and read the letter.

Past continuous for background actions

Use the past continuous for an action already in progress when another event happened. It also helps you describe the scene.

• She was helping her grandfather when she found the notebook.
• While her grandfather was watching, Mia searched near the roots.

Past perfect for an earlier event

Use the past perfect when you look back from one past moment to an even earlier event. This makes the order of events clear.

• Her grandfather and his sister had hidden the box fifty years earlier.
• Mia heard stories that she had never heard before.

A common mistake is to use the past perfect for every action. Once the earlier time is clear, return to the past simple for the main storyline.

Would for the future viewed from the past

When a character thinks or predicts something that is still in the future at that point in the story, use would.

• He said that she would understand soon.
• Mia hoped the box would contain an answer.

4. Link events and control the pace

Time expressions help readers follow the action: at first, while, as soon as, a few minutes later, after that, eventually and that evening. Use them where they clarify the order, but avoid beginning every sentence with “Then”.

Use and to add information, but for contrast, because for a reason and so for a result. Words such as when, while, before and after create complex sentences and show how two events are related.

5. Show feelings through reactions

Stories become more engaging when readers understand how the characters feel. You can place an adjective at the beginning of a sentence, followed by a comma:

• Curious, Mia turned the photograph over.
• Excited, she opened the metal box.
• Relieved, her grandfather recognised the missing letter.

Choose an adjective that truly matches the situation. For example, a person who receives good news may be delighted or relieved, while a person who makes a public mistake may feel embarrassed.

6. Add variety without making the story difficult to follow

At B1 level, accuracy and clarity matter more than extremely complicated language. However, a small range of structures can make your writing stronger. You might include a passive form, a relative clause or a conditional sentence.

• The box had been buried beneath the leaves.
• The photograph showed a girl who looked like Mia.
• If Mia had not found the notebook, they would never have discovered the box.

Use these structures only when they fit the story naturally. Do not add an advanced sentence if you are unsure that it is correct.

7. Keep the reader interested

Specific details are usually more effective than long descriptions. A “small metal box beneath the leaves” creates a clearer picture than “something interesting”. You can also use short dialogue, a question, or a clue to build suspense. Every detail should support the main event.

Common mistakes to avoid

• Changing or ignoring the given first sentence.
• Moving between past and present tenses without a reason.
• Introducing too many characters or unrelated events.
• Using then in almost every sentence.
• Writing a surprising ending that has no connection to the story.
• Forgetting paragraphs, capital letters or past-tense verb forms.

Final checklist for a B1 past story

• Did I use the exact given sentence as my opening?
• Does my story have a clear beginning, middle and ending?
• Did I use the past simple for the main events?
• Did I include the past continuous or past perfect where useful?
• Are my linking words accurate and varied?
• Do the characters’ feelings match the events?
• Did I check irregular verbs, punctuation and spelling?

Plan briefly, tell one focused story, and leave a few minutes to edit. A simple narrative with accurate tenses and a meaningful ending is more effective than a complicated story that readers cannot follow.
