Primary 4 English Quiz — Grammar

Answer Key and Marking Notes

Section A: Subject-Verb Agreement (5 × 1 mark = 5 marks)

Question 1
Answer: (2) are
Explanation: "The cat and the dog" is a compound subject joined by "and," which requires a plural verb. "Are" agrees with the plural subject in the present continuous tense ("playing").
Common mistake: Students may choose (1) "is" if they focus only on the first noun ("cat") and ignore the compound subject.

Question 2
Answer: (2) brings
Explanation: "Every" before a singular noun ("pupil") makes the subject singular, so the verb must be singular ("brings").
Common mistake: Students may pick (1) "bring" because they associate "pupil" with a group, but "every" forces singular agreement.

Question 3
Answer: (3) went
Explanation: "Last Saturday" signals past tense. "My mother and I" is a plural subject, and the past tense of "go" is "went."
Common mistake: Students may choose (4) "gone" without a helping verb; "gone" cannot stand alone as the main verb.

Question 4
Answer: (3) sing
Explanation: The relative clause "who ____ in the choir" modifies "children" (plural), so the verb must be plural ("sing").
Common mistake: Students may select (1) "sings" if they mistakenly treat "who" as singular.

Question 5
Answer: (2) knows
Explanation: With "neither…nor," the verb agrees with the subject closest to it. "The girl" is singular, so the verb is "knows."
Common mistake: Students may choose (1) "know" by treating both subjects as a compound plural.

Section B: Tenses (5 × 1 mark = 5 marks)

Question 6
Answer: cycled
Explanation: "Last Saturday" indicates simple past tense. The past tense of "cycle" is "cycled."
Marking note: Accept "cycled" only. Do not accept "was cycling" (past continuous changes the meaning slightly and does not match the simple past context).

Question 7
Answer: are preparing
Explanation: "At this very moment" signals the present continuous tense. The plural subject "students" takes "are preparing."
Common mistake: Students may write "prepare" (simple present) if they overlook the time marker.

Question 8
Answer: will have cooked
Explanation: "By the time we arrive" refers to a future completion point. The future perfect tense ("will have cooked") is used for an action that will be completed before a specified future time.
Common mistake: Students may write "will cook" (simple future), which does not convey completion before the arrival.

Question 9
Answer: boils
Explanation: A general truth or scientific fact uses the simple present tense. "Water" is singular, so the verb is "boils."
Common mistake: Students may write "is boiling" (present continuous), which describes an ongoing action rather than a universal fact.

Question 10
Answer: rains
Explanation: In a first conditional sentence (real/likely future condition), the "if" clause uses the simple present ("rains") and the main clause uses "will."
Common mistake: Students may write "will rain" in the "if" clause, which is grammatically incorrect in standard first conditional structures.

Section C: Pronouns and Articles (5 × 1 mark = 5 marks)

Question 11
Answer: (1) herself
Explanation: The reflexive pronoun must agree with the subject "Mei Ling" (singular, female). "Herself" is the correct singular feminine reflexive pronoun.
Common mistake: Students may choose (3) "themselves" if they confuse the subject with a plural group.

Question 12
Answer: (2) us
Explanation: "Asked" is a transitive verb requiring an object pronoun. "Us" is the objective case of "we."
Common mistake: Students may select (1) "we," which is a subject pronoun and cannot function as the object of a verb.

Question 13
Answer: (3) The
Explanation: The superlative adjective "tallest" requires the definite article "the."
Common mistake: Students may choose (1) "A," but "a tallest" is grammatically incorrect with superlatives.

Question 14
Answer: (2) an
Explanation: "Engineer" begins with a vowel sound (/ɛ/), so the indefinite article "an" is used instead of "a."
Common mistake: Students may pick (1) "a" if they apply the rule based on spelling rather than sound.

Question 15
Answer: (1) another
Explanation: "One another" is a reciprocal pronoun used for actions involving more than two people. It fits the context of pupils sharing in a group.
Common mistake: Students may choose (2) "other," but "one other" is not a standard reciprocal expression in this context.

Section D: Sentence Transformation (3 × 2 marks = 6 marks)

Question 16
Answer: Although the weather was hot, the boys continued playing football.
Marking scheme:

• 1 mark for correct use of "although" as a subordinating conjunction.
• 1 mark for correct sentence structure (no grammatical errors, both clauses preserved).
  Acceptable variation: "The boys continued playing football although the weather was hot."
  Common mistake: Writing "but" instead of "although" — "but" is a coordinating conjunction and does not fulfil the transformation requirement.

Question 17
Answer: The plants were watered by the gardener every morning.
Marking scheme:

• 1 mark for correct passive construction ("were watered").
• 1 mark for correct agent placement ("by the gardener") and retention of the time phrase ("every morning").
  Working:
• Active: Subject (The gardener) + Verb (watered) + Object (the plants) + Adverbial (every morning).
• Passive: Object becomes subject (The plants) + "be" in correct tense (were) + past participle (watered) + by + original subject (the gardener) + adverbial (every morning).
  Common mistake: Omitting "by the gardener" — while sometimes acceptable in passive voice, the full transformation at P4 level should retain the agent for clarity.

Question 18
Answer: The teacher told the pupils to complete their homework by the next day.
Marking scheme:

• 1 mark for correct reporting verb change ("said" → "told the pupils" or "asked the pupils").
• 1 mark for correct tense and pronoun shift ("your" → "their"; "tomorrow" → "the next day"; "please complete" → "to complete").
  Acceptable variation: "The teacher asked the pupils to complete their homework by the following day."
  Common mistake: Keeping "tomorrow" instead of changing it to "the next day" or "the following day" — reported speech requires time reference adjustment.

Section E: Editing — Grammar Errors (2 × 2 marks = 4 marks)

Question 19
Error: "was" (incorrect verb — subject-verb agreement error)
Corrected sentence: The children were excited to visit the Singapore Zoo last weekend.
Marking scheme:

• 1 mark for correctly identifying the error ("was" should be "were").
• 1 mark for writing the full corrected sentence with the right verb.
  Explanation: "Children" is a plural noun and requires the plural verb "were," not the singular "was."

Question 20
Error: "have" (incorrect verb — subject-verb agreement error)
Corrected sentence: Each of the students has submitted their project on time.
Marking scheme:

• 1 mark for correctly identifying the error ("have" should be "has").
• 1 mark for writing the full corrected sentence with the right verb.
  Explanation: "Each" is a singular determiner, so the subject "each of the students" is singular and requires the singular verb "has."
  Note: Some modern usage accepts "their" with "each" to avoid gendered language; at P4 level, do not penalise "their" in the corrected sentence.
