GRAMMAR IN USE: VERBS AND TENSES

Subject: English — Topic: Consumer Roles and Responsibilities
Audience: Kenyan learners, age 13. Examples use local contexts (market, matatu, shop, warranty).

1. What is a verb?

A verb is a word that shows an action or a state. In consumer contexts, verbs tell us what buyers and sellers do.

Examples: buy, pay, complain, return, check, read.

E.g. "I buy maize at the market." 🛒 "We check the expiry date." ✅

2. Important tenses and verbs

Present Simple

Form: base verb (he/she/it + s). Use: regular habits, facts, and rights.

Examples (consumer):

  • "Shops open at 8:00." (fact)
  • "A consumer has the right to a receipt." (general truth)
  • "He pays for maize every Saturday." (habit)

Signal words: usually, always, every, often

Present Continuous

Form: am/is/are + verb+ing. Use: actions happening now or temporary actions.

Examples:

  • "I am checking the prices now." 🧐
  • "They are opening a new shop on the corner." (temporary or in progress)

Signal words: now, at the moment, currently

Past Simple

Form: verb + ed (regular) or irregular forms. Use: completed actions in the past.

Examples:

  • "I bought sugar yesterday." 🛍️
  • "She complained to the manager last week." (completed)

Signal words: yesterday, last week, in 2023

Present Perfect

Form: have/has + past participle. Use: actions that connect past to now (experience, changes, unfinished time).

Examples:

  • "I have paid for the bus fare." 🚌
  • "We have bought fresh tomatoes today." (experience or result now)
  • "They have complained about the poor service." (result matters now)

Signal words: already, yet, just, ever, never

Future (will / going to)

Use: predictions, intentions, plans.

  • "I will ask for a receipt." (decision)
  • "We are going to buy a new phone next month." (plan)

Signal words: tomorrow, next week, soon, going to

Modal verbs for duties and permissions

Use modals to show obligation, permission, or advice.

  • "must / have to" = strong obligation: "You must keep the receipt."
  • "should" = advice: "You should check expiry dates."
  • "can" = permission/ability: "You can exchange faulty items."
  • "may" = polite permission (less common in spoken Kenyan English): "You may speak to the manager."

Passive voice (useful for consumer information)

Form: be + past participle. Use when the action is more important than who did it.

Examples:

  • "The goods were delivered yesterday." (who delivered is not important)
  • "A refund is given when the product is faulty."

Imperative (giving instructions)

Use the base verb to give instructions or commands.

Examples:

  • "Show your receipt." ✔️
  • "Read the label before you buy." 📋

3. Quick grammar guide (at a glance)

4. Practice exercises

  1. Fill in the correct tense or modal:
    1. "I ______ (buy) maembe every Friday." (habit)
    2. "She ______ (check) the expiry date now." (happening now)
    3. "They ______ (complain) to the manager yesterday." (past)
    4. "We ______ (have) the receipt, so we can get a refund." (present perfect)
    5. "You ______ (must/should) keep your receipt when you pay." (strong obligation)
    6. "This phone ______ (be) sold yesterday." (passive — past)
  2. Change to negative or question:
    1. Positive: "He pays for the bus." → Negative: __________________
    2. Positive: "You will ask for a receipt." → Question: __________________
  3. Choose the best modal (must / should / can) to complete:
    1. "You ______ return the faulty kettle for a replacement." (advice or obligation)
    2. "Customers ______ bring identity when collecting goods on credit." (rule)

5. Quick tips for exams and daily life

  • Match the tense with the time words: "yesterday" → past; "now" → present continuous; "already/just" → present perfect.
  • Use modals when talking about rights and duties: "must" for rules, "should" for advice.
  • In receipts and notices you often see passive: "refunds are given" — read carefully!
  • Practice by writing a short diary: "Today I bought..." (past) and "I am going to..." (future plan).
