🔗 Synthesis & Transformation
Synthesis & Transformation is one of the most predictable and scoreable components in PSLE English. It tests your ability to combine two sentences into one or transform a sentence by changing its structure. Found in Paper 2, Booklet B, it is worth 10 marks (5 questions x 2 marks each).
Unlike comprehension or composition, where answers can vary, Synthesis & Transformation has fixed patterns— there is usually only one correct answer. This means that once you memorise the patterns and practise regularly, you can score full marks every time. Many top PSLE scorers consider this section their "guaranteed 10 marks."
This chapter covers all 28 patterns that have appeared in past PSLE papers, with detailed explanations of the three hardest transformations: reported speech, active/passive voice, and relative clauses. You will also find common mistakes to avoid and practice questions at the end.
🔗How Synthesis & Transformation Works
In each question, you will be given either two sentences to combine into one (synthesis) or one sentence to rewrite in a different form (transformation). The question will always specify the connector or structure you must use. For example: "Combine the sentences using 'Although'."
5-Step Approach to Synthesis & Transformation
Read Both Sentences Carefully
Understand the meaning of both sentences. Identify which sentence contains the main idea and which contains the secondary information (contrast, reason, condition, etc.).
Identify the Required Pattern
Look at the instruction word (Although, Unless, so...that, who, etc.). This tells you exactly which pattern to use. If you have memorised the patterns, this step takes seconds.
Apply the Pattern
Place the connector in the correct position. Remember: some connectors go at the start (Although, Unless, As soon as), some go in the middle (who, which, so...that), and some replace words (too...to replaces "very...could not").
Check for Necessary Changes
After combining, you may need to: remove repeated words, change pronouns (he/she/they), adjust verb tenses, or add/remove punctuation. Read your combined sentence aloud to check it sounds natural.
Verify Meaning is Preserved
The combined sentence MUST mean the same as the original two sentences. If the meaning has changed, you have made an error. Go back and check your connector placement and word changes.
