9.3 Grammar in Use — Notes for learners (Age 15, Kenya)

Subtopics: 9.3.1 Sentences • 9.3.2 Subject–Verb Agreement


Specific Learning Outcomes

  • (a) Explain basic rules of subject–verb agreement in sentences.
  • (b) Apply agreement rules when using count and non‑count nouns.
  • (c) Construct active and passive sentences in oral and written texts.
  • (d) Use count and non‑count nouns correctly in sentences.
  • (e) Advocate for the use of varied sentences in communication.
  • (f) Identify active voice, passive voice, count nouns and non‑count nouns.

1. What is a sentence?

A sentence is a group of words that gives a complete thought. Every sentence has a subject (who or what) and a predicate (the verb and information about the subject).

Simple example:

The farmer harvests maize. (Subject = The farmer. Verb = harvests. Object = maize.)

2. Subject–Verb Agreement — basic rules

  • Singular subject → singular verb. Example: He walks, The teacher explains.
  • Plural subject → plural verb. Example: They walk, The students explain.
  • For most verbs in present simple add -s or -es for third person singular: she runs, it watches.
  • Use the correct form of ā€œbeā€ and auxiliary verbs: is/are, has/have, does/do.
  • With compound subjects joined by and, use a plural verb: The mother and father are at the market.
  • With subjects joined by or / nor, the verb agrees with the nearest subject: Neither the students nor the teacher is ready. vs Neither the teacher nor the students are ready.
  • Collective nouns (team, family, committee) are usually treated as singular: The team is winning (British and Kenyan English often treat as singular).

3. Count and non‑count nouns — effect on agreement

Count nouns (can be counted) have singular and plural forms: mango / mangoes, student / students. Non‑count nouns (mass nouns) do not take plural forms and use singular verbs: rice, water, tea, maize, advice.

  • Count noun example: One mango is ripe. Five mangoes are on the tree.
  • Non‑count example: The maize is wet. Sugar is sweet.
  • Quantifiers: some, all, most, a lot of — verb depends on whether the noun is count or non‑count:
    • Some students are absent. (students = plural)
    • Some rice is left. (rice = non‑count → singular verb)
  • Amounts used as a single unit take singular verbs: Ten litres of water is enough.

4. Active and passive voice — how to form and when to use

Active: subject performs the action. Passive: subject receives the action.

Make passive in 3 steps:
  1. Make the object of the active sentence the subject of the passive sentence.
  2. Use the correct form of be + past participle (match the tense).
  3. Optionally add by + agent to show who performed the action.

Examples (present simple):

Active: The teacher explains the exam.

Passive: The exam is explained by the teacher.

Examples with Kenyan context:

  • Active: The farmer waters the tea plants. → Passive: The tea plants are watered by the farmer.
  • Active: Students read the notice. → Passive: The notice is read by students.

5. How this fits the learning outcomes (short mapping)

  • (a) & (b) Rules in sections 2–3 explain and show count vs non‑count agreement.
  • (c) Section 4 shows how to construct active and passive sentences.
  • (d) Count / non‑count examples in section 3 help use nouns correctly.
  • (e) Section 6 gives ways to vary sentences for better communication.
  • (f) Exercises below ask learners to identify active/passive and noun types.

6. Tips for writing and speaking (advocate varied sentences)

  • Mix short and long sentences: short for emphasis, longer for detail.
  • Prefer active voice when you want clear, direct sentences. Use passive when the action or result is more important than the actor.
  • Use a variety of sentence types (simple, compound, complex) to hold the reader's interest.
  • Check noun types: if unsure whether a noun is count or non‑count, try to add numbers — if numbers work (one mango, two mangoes) it is count; if not (one rice āŒ) it is non‑count.

7. Practice exercises (do these in class or at home)

  1. Choose the correct verb:
    1. The teacher (is / are) ready.
    2. Some of the maize (was / were) eaten by goats.
    3. My sister and I (visit / visits) the market on Saturdays.
    4. Either the driver or the conductors (is / are) responsible.
    5. A lot of sugar (is / are) used in the tea.
  2. Identify whether the underlined noun is count or non‑count (write Count or Non‑count):
    1. rice
    2. students
    3. advice
    4. mango
  3. Change these active sentences to passive:
    1. The school organised the football match.
    2. Farmers harvest tea leaves early in the morning.
  4. Identify voice and noun type (example answer format: Active; Count):
    1. The maize is stored in the granary.
    2. Two students have completed the project.

Answers

  1. a) is; b) were (if maize counted as separate small units eaten; more common: was eaten — accept both if explained); c) visit; d) are (nearest subject 'conductors' plural); e) is
  2. a) Non‑count; b) Count (plural); c) Non‑count; d) Count
  3. a) The football match was organised by the school. b) Tea leaves are harvested early in the morning by farmers.
  4. a) Passive; Non‑count. (The sentence is passive: "is stored"; maize = non‑count.) b) Active; Count. (Two students = plural count; verb 'have' plural.)

8. Classroom activities (10–20 minutes each)

  • Pair activity: Give each pair 6 sentences. One student changes active → passive, the other checks subject–verb agreement and noun type.
  • Group editing: Provide a short paragraph (Kenyan context — e.g., school harvest day). Students rewrite to use varied sentences and correct agreement.
  • Role play: One student reads a short report in active voice; another rewrites it for radio (use passive where needed), then present.

9. Assessment checklist for teachers

  • Can the learner identify subject and verb in a sentence?
  • Can the learner choose correct verb forms for singular/plural and for count/non‑count nouns?
  • Can the learner convert sentences between active and passive with correct tense and agreement?
  • Does the learner use a variety of sentence structures in a short writing task?

Note: Use local examples (maize, tea, matatu, market, harvest) when practising. Encourage learners to explain why a verb form is correct — this builds understanding, not just memorisation.
