• A simple sentence makes a single statement - for example, I turned the corner.
• Compound sentences are simple sentences linked by conjunctions or joining words - for example, The sun dazzled me, so I couldn't see anything.
• Complex sentences are those with a main statement and additional statements (called 'clauses') - for example: I crashed into the Mini, which was parked on the street just beyond the junction.

Tips for writing:

• You do not always have to use complex sentences. Use a balance of different sentence types to make your writing clear and so that it flows well and reads easily.
• Do not allow your sentences to get so long that they are hard to read.

Tips for answering test questions:

• Some test questions ask you to complete or create complex sentences by choosing the best words to fill a gap. Always read the whole paragraph carefully to see which answer makes most sense in the text.
