👋 What this unit is really about

Here's 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 — 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 clauseswhen, as soon as, by the time, before, after — 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'll write an apology dialogue, a pie-chart description, and a 200-word essay on managing time.

📜 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 — and the examiner notices. Don't just drop it and run, though: quote it, then answer it. "Franklin called time money. He was wrong — it's worse than money, because you can earn money back."

  • "Remember that time is money." — Benjamin Franklin
  • "Time stops for no one."
  • "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

📝 Time lost — 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 — but to the student who just failed a final, a whole year is everything. A millisecond is invisible — 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. Read it slowly and feel each one.

📐 Grammar — Time clauses — when · as soon as · by the time · while · before · after கால ஒட்டுச் சொற்கள்

A time clause ties one action to another in time — 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 little hinge-words — when, as soon as, by the time, while, before, after — are everywhere in everyday speech.

But here is the one rule that catches almost everyone, so let it sink in. 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" — not "as soon as I will reach". Think of it this way: English only lets you put one "will" in the sentence — 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". One future marker per sentence; the time clause travels in the present.

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" ✗. 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 — and it lives in the main half.
📋 Quick recall Time clause = hinge pinning one action to another (when, as soon as, by the time, while, before, after). After the time word the verb stays present, never future: "as soon as I reach", not "will reach".

📐 Grammar — Polite apologies for being late மன்னிப்புக் கேட்கல்

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. Picture walking in late to your master-in-charge — the four moves carry you through it without fumbling.

  1. Open with sorry — 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."

And notice the other half of the exchange, because the exam often asks for the teacher's reply too. 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 recall Apology in four moves: sorry → honest reason → promise → accept the consequence. Teacher's reply = advice + warning ("you should… · otherwise…").

📐 Grammar — Pie-chart description — the five phrases that win marks பை வரைபடம்

Describing a pie chart isn't about listing every slice — 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. Hit those phrases and the marks are yours; just reciting numbers without comparing them is what loses them.

  • The highest percentage goes to Studying at 34%. (start big)
  • The lowest percentage goes to Relaxing at 4%. (then smallest)
  • 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 — "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 recall Walk the chart like a guide: highest → lowest → equal pair → more-than/less- than pair, then one summary line of meaning. Compare, don't just list.

✍️ Writing — Dialogue of apology (~80 words)

⭐ What the exam asks about this unit

Glance over this before you revise. Pie-chart and bar-graph description is a guaranteed Test 14 task — 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 away
  • Putting "will" after a time word — "as soon as I will reach". The time clause stays present.
  • Describing a pie chart by just listing slices — you must compare (highest/lowest/equal/more-than) and add a summary line.
  • Misreading the data — one wrong percentage costs an accuracy mark; copy the figures carefully.
  • An apology with no honest reason or no promise — markers want the full four-part shape.
  • Forgetting the teacher's reply needs advice + warning, not just "okay, sit down".

🎯 Test yourself before you move on

Cover the answers — say each one out loud first
  • 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 — it sits in the main half; the time clause is already understood as future.
  • Name the four moves of a good apology. → Sorry → honest reason → promise → 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.

Kavindi was the kind of student who always meant to start early but never

freshly opened past papers and one fresh cup of tea — and a notification
from her best friend. "Just five minutes," she promised herself, and tapped
the screen.

Three hours later, she looked up. The tea had gone cold; the papers had not
been touched. Her mother knocked. "Aren't you starting?" Kavindi nodded
bravely and reached for the past paper. Now, in three hours, she had to do
what should have taken eight.

That night, after the exam, she walked the long way home so her mother
wouldn't see her cry. She had not failed — but she knew, exactly, what nine As
felt like and what eight As felt like, and the difference, she realised, was
three wasted hours on a Monday morning.
