1 Why this unit is really about 168 identical hours

Here is a fact worth sitting with: every student in Sri Lanka gets exactly the same 168 hours a week. Not one minute more for the nine-A student, not one minute less for the one who struggles. So why the huge gap in results? Almost never raw cleverness β€” it's what each of them does with those identical hours. This unit gives you the English to talk about time: to discuss it, apologise when you've wasted someone else's, and describe how a day is split up.

The grammar that fits is time clauses β€” when, as soon as, by the time, before, after β€” the little hinge-words that pin one action to another, plus the polite shape of an apology and the phrases for describing a pie chart. You will write an apology dialogue, a pie-chart description, and a 200-word essay on managing time.

2 Famous sayings about time

Keep one of these in your back pocket. An essay that opens with a sharp quotation sounds like it knows where it's going from the first line β€” and the examiner notices. Don't just drop it and run, though: quote it, then answer it. "Franklin called time money. He was wrong β€” it's worse than money, because you can earn money back."

SayingWho said it
"Remember that time is money."Benjamin Franklin
"Time stops for no one."β€”
"Time is what we want most, but what we use worst."William Penn
"One always has time enough, if one will apply it well."Goethe
"A man who dares to waste one hour of time has not discovered the value of life."Charles Darwin

3 Time lost β€” who would know the value of it?

This little table from the textbook does something clever: it teaches the value of time by changing who is counting it. A year is nothing to most of us β€” but to the student who just failed a final, a whole year is everything. A millisecond is invisible β€” until you're the heart surgeon whose hand slips. The lesson hiding inside the table is that time isn't measured in clocks; it's measured in what each person stands to lose.

4 Grammar β€” time clauses: when Β· as soon as Β· by the time Β· while Β· before Β· after

A time clause ties one action to another in time β€” it answers "when does the main thing happen?" "I will call you as soon as I reach home." The first half is the plan; the time clause pins it to a moment. These hinge-words β€” when, as soon as, by the time, while, before, after β€” are everywhere in everyday speech.

But here is the one rule that catches almost everyone. After a time word, the verb stays in the present even when the meaning is clearly future. We say "I will call you as soon as I reach home" β€” not "as soon as I will reach". English only lets you put one "will" in the sentence β€” it goes in the main half (the plan), and the time clause is already understood to be future, so it doesn't need its own "will".

WordUseExample
whenat the moment ofWhen the bell rings, we leave the class.
as soon asimmediately afterI will call you as soon as I reach home.
by the timeat or before that pointBy the time you arrive, lunch will be ready.
whileduring, simultaneouslyRead while you wait for the bus.
beforeearlier thanFinish your homework before you watch TV.
afterlater thanI shower after I exercise.
The slip everyone makes"I will call you as soon as I will reach home" is wrong. After as soon as / when / before / after / by the time / while, the verb stays in the present even with a future meaning. One "will" per sentence β€” and it lives in the main half.
Quick recallTime clause = hinge pinning one action to another. After the time word the verb stays present, never future: "as soon as I reach", not "will reach".

5 Grammar β€” polite apologies for being late

Saying sorry well is a skill, and the exam rewards a particular four-step shape because it's how a sincere apology actually works in real life. A mumbled "sorry sir" earns little; an apology that owns the lateness, explains it honestly, promises better, and accepts the cost sounds genuinely mature.

  1. Open with sorry β€” and mean it: "I'm very sorry sir, for being late this morning."
  2. Give an honest reason (not an excuse): "Our train was delayed by 40 minutes due to a signal failure."
  3. Promise it won't repeat: "It will not happen again."
  4. Accept the consequence: "I am ready to take any punishment you give us."

The other half of the exchange matters too, because the exam often asks for the teacher's reply. It almost always carries advice plus a warning: "You should leave home earlier from now on. Otherwise you will be marked absent." That should/otherwise pair is your signal the reply is doing its job.

Quick recallApology in four moves: sorry β†’ honest reason β†’ promise β†’ accept the consequence. Teacher's reply = advice + warning ("you should… otherwise…").

6 Grammar β€” pie-chart description: the five phrases that win marks

Describing a pie chart isn't about listing every slice β€” it's about comparing them, and the examiner is literally hunting for five comparison phrases. Think of yourself as a tour guide walking the reader round the chart: start at the biggest slice, swing down to the smallest, point out any two that are equal, and pick out a "more than / less than" pair.

Sample data: how a Grade 11 student spends the dayThe highest percentage goes to Studying at 34%. The lowest percentage goes to Relaxing at 4%. An equal amount of time is spent on Classes and Eating (8% each). More time is spent on Sleeping (29%) than on Travelling (17%). Less time is spent on Relaxing than on any other activity.

The finishing touch that lifts a description from "fine" to "very good": after the comparisons, add one line of meaning β€” "in short, almost two-thirds of the day goes to studying and sleeping." The examiner wants to see you understood the chart, not just read it.

Quick recallWalk the chart like a guide: highest β†’ lowest β†’ equal pair β†’ more-than/less-than pair, then one summary line of meaning. Compare, don't just list.

7 Writing β€” the apology dialogue and the pie-chart description

The model dialogue between Hassan, Rajan and their master-in-charge marches through the four apology moves without ever feeling like a checklist. The boys open with respect ("Good morning sir") and an immediate apology, give an honest reason specific enough to be believable (a 40-minute delay, a named station β€” Nugegoda), promise it won't repeat, and accept the teacher's authority. The master's reply does its own job perfectly: advice plus warning β€” "you should leave earlier… otherwise you will be marked absent."

The pie-chart model description on how a Grade 11 student spends the day is built exactly on the five phrases: it opens by saying what the chart is, then walks the data as a guide would β€” highest (studying 34%), the runner-up, a more-than comparison (travelling vs relaxing, "more than three times"), an equal pair (classes and eating, 8% each), and the lowest (relaxing 4%). Crucially it doesn't stop at the numbers β€” the last two sentences add meaning ("almost two-thirds… a worrying balance"), which is the line that earns the top band.

8 What the exam asks about this unit

Pie-chart and bar-graph description is a guaranteed Test 14 task β€” worth ten marks that come easily once you've drilled the five phrases. Time clauses turn up in the verb-form passages, and "time management / value of time" is a regular essay theme. The apology shape feeds the dialogue tasks.

Where students throw marks awayPutting "will" after a time word β€” "as soon as I will reach": the time clause stays present. Describing a pie chart by just listing slices β€” you must compare (highest/lowest/equal/more-than) and add a summary line. Misreading the data β€” one wrong percentage costs an accuracy mark. An apology with no honest reason or no promise. Forgetting the teacher's reply needs advice + warning, not just "okay, sit down".
Test yourself β€” say each answer out loud before reading it
Fix: "I will text you as soon as I will land." "…as soon as I land." The time clause stays present.
Why no "will" after "when / as soon as"? English allows one future marker per sentence β€” it sits in the main half; the time clause is already understood as future.
Name the four moves of a good apology. Sorry β†’ honest reason β†’ promise β†’ accept the consequence.
What two things does the teacher's reply carry? Advice + a warning ("you should… otherwise…").
Which slice do you mention first in a pie chart, and last? The highest first, then work toward the lowest.
What lifts a chart description into the top band? A final line of meaning that interprets the data, not just lists it.
