YEAR 8 · 10-MINUTE BOOSTER

Give sentences clear boundaries

Recognise when two complete ideas need a full stop or a suitable conjunction.

Before you try

A main clause can stand as a sentence: 'The doors opened.' Two main clauses cannot normally be joined by a comma alone in standard written English.

You can separate them with a full stop, or join them with a suitable conjunction such as 'but' or 'so'. Choose according to the relationship between the ideas, not simply to make the sentence longer.

Read this

11. The bus stopped, the doors opened.

22. Amira wanted to ask a question, she kept her hand under the desk.

33. The path was flooded, we took the longer route.

44. Although the hall was noisy.

Original practice text created for The English Practice. People and situations are fictional.

Your turn

  1. Repair sentence 1 using two sentences. Repair sentence 2 using 'but' and sentence 3 using 'so'. Keep the original meaning.
  2. Explain why sentence 4 is incomplete as it stands. Add a main clause to finish it.
  3. Write your own sentence using 'but' to join two complete, contrasting ideas. Check that each side could stand alone.

Make your own attempt before opening the model below. If you are stuck, revisit the explanation; you can use a model to help, then try again in your own words.

Suggested answers and explanation

1. The bus stopped. The doors opened.

2. Amira wanted to ask a question, but she kept her hand under the desk.

3. The path was flooded, so we took the longer route.

4. 'Although' makes us expect another idea: despite the noise, what happened? One possible completion is: Although the hall was noisy, I heard my name.

My own example: The box looked light, but I could barely lift it.

Why it works

  • The full stop separates two complete statements without changing their meaning.
  • 'But' signals contrast; 'so' signals a result. They do different jobs.
  • The added main clause completes the thought begun by 'Although'.

A model illustrates the thinking, not a script to memorise. Different wording or an alternative interpretation can work when it answers the task and is properly supported.

Check your work

Tick a check only when you can point to it in your answer. These ticks are not sent to us or recorded as a progress score.

Make one improvement

Choose your own 'but' sentence. Read each main clause aloud separately, then check that the contrast between them makes sense.

Want a further challenge? Optional stretch

Try joining the two clauses in sentence 1 with a semicolon. Explain why a semicolon can work there but cannot, on its own, complete sentence 4.

Allow extra time for this. It is not part of the 10-minute booster.

Before moving on, explain one choice you improved. Finishing an activity is practice, not proof that a skill is secure; try applying it again in fresh work.
