Primary 4 English Quiz - Synthesis Transformation: Answer Key

Total Marks: 20


Section A: Combining Sentences (Questions 1 - 5)

1. The children continued playing in the park although they were tired. (Accept: Although the children were tired, they continued playing in the park.) Marks: 1 Teaching Note: 'Although' is used to show a contrast between two ideas. The first idea (being tired) does not stop the second idea (continuing to play). When 'although' starts the sentence, a comma is needed after the first clause. Common Mistake: Forgetting the comma when starting with 'Although'.

2. We missed the beginning of the movie because the bus was late. (Accept: Because the bus was late, we missed the beginning of the movie.) Marks: 1 Teaching Note: 'Because' is used to show a cause-and-effect relationship. The bus being late is the reason (cause) for missing the movie (effect). When 'because' starts the sentence, a comma is needed after the first clause.

3. You must finish your homework before you can watch television. Marks: 1 Teaching Note: 'Before' is used to show the order of events. Finishing homework happens first, then watching television. The verb after 'before' is often in the present tense when talking about a general rule.

4. The little girl was hungry, but she did not want to eat the vegetables. Marks: 1 Teaching Note: 'But' is used to show a contrast. The girl's hunger (one idea) is contrasted with her refusal to eat vegetables (another idea). A comma is placed before 'but' when joining two complete sentences.

5. We went out to play after the rain stopped. (Accept: After the rain stopped, we went out to play.) Marks: 1 Teaching Note: 'After' shows the order of events. The rain stopping happens first, then going out to play. When 'after' starts the sentence, a comma is needed after the first clause.


Section B: Using the Given Word (Questions 6 - 10)

6. The bag is so heavy that I cannot carry it. Marks: 1 Teaching Note: The structure 'so...that' is used to show a result. The pattern is: 'so' + adjective + 'that' + result clause. Here, the bag's heaviness (adjective) results in the speaker not being able to carry it.

7. Mrs Lim told John that she would help him with his project. Marks: 1 Teaching Note: This is a reported speech transformation. When changing direct speech to reported speech, the tense shifts back (will → would), and pronouns change (I → she, you → him, your → his). The word 'that' is used to connect the reporting verb to the reported clause.

8. It was such a boring movie that we left the cinema early. Marks: 1 Teaching Note: The structure 'such...that' is used to show a result. The pattern is: 'such' + (a/an) + adjective + noun + 'that' + result clause. Here, the boring movie (adjective + noun) results in leaving the cinema early.

9. The boys were punished for being late for class. Marks: 1 Teaching Note: 'For' is used to show the reason for an action. The reason for the punishment is being late. The verb 'were late' changes to the gerund form 'being late' after the preposition 'for'.

10. This is the book which I borrowed from the library. Marks: 1 Teaching Note: 'Which' is a relative pronoun used to connect two sentences about a thing. It replaces the noun 'book' in the second sentence. The pattern is: noun + 'which' + relative clause.


Section C: Changing Sentence Structure (Questions 11 - 15)

11. The teacher told the pupils to keep quiet. Marks: 1 Teaching Note: This is a reported speech transformation for a command. The pattern for commands is: reporting verb (told) + object (the pupils) + 'to' + base verb (keep). The word 'please' is removed in reported commands.

12. The children were too excited to sleep. Marks: 1 Teaching Note: The structure 'too...to' is used to show that something is excessive and prevents an action. The pattern is: 'too' + adjective + 'to' + base verb. Here, being too excited prevents sleeping.

13. The car is too expensive for anybody to afford. (Accept: The car is too expensive for anyone to afford.) Marks: 1 Teaching Note: The structure 'too...to' can be extended with 'for' + person to show who is affected. The pattern is: 'too' + adjective + 'for' + person + 'to' + base verb. Here, the car's high price prevents anyone from affording it.

14. The boy who is playing in the garden is my neighbour. Marks: 1 Teaching Note: 'Who' is a relative pronoun used to connect two sentences about a person. It replaces the noun 'boy' in the second sentence. The relative clause 'who is playing in the garden' comes immediately after the noun it describes.

15. The food was too delicious for us to leave any. (Accept: The food was too delicious for us not to eat everything.) Marks: 1 Teaching Note: The structure 'too...to' can replace 'so...that' when the result is negative. The pattern is: 'too' + adjective + 'for' + person + 'to' + base verb. Here, the food's deliciousness prevents leaving any uneaten.


Section D: Synthesis with Connectors (Questions 16 - 20)

16. The team practised hard, so they won the championship. Marks: 1 Teaching Note: 'So' is used to show a result. The first clause (practising hard) is the cause, and the second clause (winning) is the result. A comma is placed before 'so' when joining two complete sentences.

17. You can have either the cake or the ice cream. Marks: 1 Teaching Note: 'Either...or' is used to present two choices. The pattern is: 'either' + option 1 + 'or' + option 2. Both options are placed after the verb 'have'.

18. Even though the boy was tired, he still finished his homework. (Accept: The boy still finished his homework even though he was tired.) Marks: 1 Teaching Note: 'Even though' is a stronger version of 'although' and shows a strong contrast. The tiredness does not stop the boy from finishing his homework. When 'even though' starts the sentence, a comma is needed after the first clause.

19. The girl studied hard so that she could pass the exam. Marks: 1 Teaching Note: 'So that' is used to show purpose or intention. The pattern is: action + 'so that' + purpose clause. Here, studying hard is the action, and passing the exam is the purpose. The modal 'could' is often used after 'so that'.

20. Despite being very rich, the man is not happy. (Accept: The man is not happy despite being very rich.) Marks: 1 Teaching Note: 'Despite' is used to show contrast and is followed by a noun or gerund (-ing form), not a full clause. The pattern is: 'Despite' + noun/gerund + comma + main clause. Here, 'being very rich' is the gerund phrase that contrasts with not being happy. Common Mistake: Using 'despite of' instead of 'despite', or using a full clause after 'despite' (e.g., 'Despite he is rich').
