For A Better Tomorrow

The polythene bag you toss into the canal on the way to school today will still be lying there when your own grandchildren sit their O/Ls. Plastic doesn't rot — it just breaks into smaller and smaller pieces and waits. That single, uncomfortable fact is what this whole unit is about: looking at the mess we are making and learning the English to argue, clearly and calmly, for a better tomorrow.

The grammar that fits is the second conditional — "if we recycled, we would save…" — the tense for imagining a better world that doesn't exist yet. You'll also nail down capitalisation (the seven small rules that quietly cost marks), and learn the shape of a TV interview and a public announcement, before writing a 200-word environment essay.

Read it again and watch the shape of the interview, because that shape is exactly what the exam asks you to reproduce. The presenter never just fires questions — he welcomes the guest ("Welcome to the programme"), the guest warms up ("It's a pleasure to be here"), then comes the first real question, and after the answer the presenter invites him to expand ("Could you tell us something about them?"). Welcome → question → invite-to-expand. Notice too how naturally the host stays polite and the expert stays clear and short. When you write your own interview script, keep that courtesy and that rhythm; markers reward the manners as much as the facts.

People mix these three up all the time, so here's the simple way to keep them straight: they go in order of how much good they do. Reduce is best because the rubbish never gets made in the first place. Reuse is next — the thing already exists, so you squeeze more life out of it before binning it. Recycle is last because it costs energy to melt something down and remake it — better than the dump, but not as good as never buying it. Reduce → Reuse → Recycle: a staircase from "best" down to "still good".

The whole spirit of this unit is "if only things were different" — and that feeling has its own tense, the second conditional. You reach for it when you imagine a world that isn't real yet but could be: "If we recycled half our waste, our dumps would shrink." Nobody is recycling half their waste today — that's the point. The second conditional is the grammar of a daydream about a better tomorrow.

Here's the analogy that makes the structure click. Think of the "if" part as taking one step back from reality into the imaginary, and English marks that step by pushing the verb into the past form — even though you're talking about now or the future. "If we recycled…" uses the past tense not because it happened, but to signal "this is pretend". Then the result half uses would, the word that means "this is what would follow, in that imagined world".

Recipe: If + past simple, ... would + bare verb.

• If we recycled half our waste, our garbage dumps would shrink in a year. (pretend condition → would-result)
• If every shopper carried a cloth bag, we would not see polythene in the canals.
• If the government banned single-use plastics tomorrow, our beaches would be cleaner by 2030.

The slip to guard against is putting "would" in both halves — "If we would recycle…". Never. The "if" half takes the plain past; only the result half gets "would". Keep would out of the if-clause and the sentence sounds right every time.

Capital letters feel too small to matter — and that's exactly why students leak marks on them. The examiner has a checklist of seven places a capital must appear, and a paragraph that misses them looks careless even when the ideas are good. The simple way to remember the list: capitals mark beginnings and names — the start of a sentence, and every kind of proper name (a person, a place, a day, a language, a title). Learn the seven and you never lose this mark again.

1. The first letter of every sentence: Scientists have not found...
2. The pronoun I, always — even in the middle of a sentence.
3. Proper nouns — names of people: Mr. Perera, Udaya.
4. Place names: Sri Lanka, Mars, Mediterranean Sea, Panadura.
5. Days, months, festivals: Saturday, August, Vesak. (But not the seasons or "today".)
6. Nationalities & languages: Chinese, Sinhalese, Tamil.
7. The main words in the title of a book / film / article: Let's Protect Our Environment — but small joining words (of, the, and) stay lower-case.

The two traps worth naming: students often forget to capitalise languages and nationalities (it's Tamil, not "tamil"), and they sometimes capitalise common nouns by mistake ("the River" when no name follows — just "the river"). Capital = a specific name; no name, no capital.
