Future

Nobody can see the future, but English gives you several ways to talk about it — and each one carries a slightly different feeling. "I will help you" is a promise made on the spot; "I am going to study medicine" is a plan you decided long ago; "By 2030 I will have built my own house" is a finish line set in the years ahead. Pick the wrong one and a sentence sounds off, even when every word is spelled right.

The bigger idea in this unit is the "if" sentence — and there are three shapes of it, sorted by how likely the dream is. One for things that might really happen, one for daydreams about now, and one for regrets about the past that can never be undone. Get those three apart and you can say exactly how possible something is. Along the way you'll meet Earth Hour, predict your own life, and write a "What if…" essay.

Earth Hour is really a single switch flicked off by hundreds of millions of people at once — a tiny act made huge by everyone doing it together. The passage is worth copying for its structure: the first paragraph tells you the plain facts (what, when, who), and the second tells you the purpose (why it matters, what it hopes to change). Whenever you write about an event or a campaign, split it the same way — facts first, then the point of it — and the reader is never confused about either.

Think of the future forms as different strengths of certainty and planning. Will is the spur-of-the-moment future — you decide as you speak ("the phone's ringing — I'll get it"), or you predict ("it will rain tomorrow"). Going to is the already-decided future — the plan was in your head before you opened your mouth ("I am going to study medicine"), or there's evidence right in front of you ("look at those black clouds, it's going to rain"). And the present continuous is for a fixed arrangement with a time already pinned to it ("I am meeting the principal at 3 p.m.").

So the quick test is: did I plan this before now? If yes → "going to"; if I'm deciding right now → "will"; if it's booked with a time → present continuous.

The future perfect deserves a special note because it's the one the exam loves: it says an action will be already complete by a future moment. Its tell-tale signal is the little word by — "by 2030", "by the time you arrive". Whenever you see "by + a future time", reach for will have + V3.

The Type 1 conditional is for a future that could really happen — there's a genuine chance, so you speak about it almost as fact. "If it rains, the match will be postponed" — rain is perfectly possible, so the consequence is spoken of plainly. The recipe is If + present simple, will + bare verb.

Here's the rule that trips everyone: even though both halves point to the future, the if-half stays in the present. English never wants two "wills" in one conditional — the "will" lives only in the result half. Think of "if" as a doorway: you step through it in the present tense, and the future waits on the other side.

• If I give you some grains, will you give me some apples?
• If it rains, the match will be postponed.
• If you study every day, you will pass your O/Ls.

You can flip the two halves around — just drop the comma when "if" comes second: "The match will be postponed if it rains."

Type 2 is the daydream conditional — for things that aren't true now and probably never will be. "If I had a million rupees, I would build a hospital" — but I don't have it, so this is pure imagination. To signal "this is only a dream", English does something clever: it pushes the verb one step into the past, even though we're talking about now. That backward step is the grammar's way of saying "not real". Recipe: If + past simple, would + bare verb.

So the past tense here isn't about time at all — it's about distance from reality. The further back the verb steps, the less real the situation. That's the single idea that separates Type 2 from Type 1.

• If I had a million rupees, I would build a hospital. (I don't have it.)
• If she worked harder, she would pass. (She doesn't work hard.)
• If I were the president, I would plant a million trees.

One oddity to memorise: in Type 2 we use were for everybody — "if I were you", "if he were here" — not "was". "If I were you…" is the fixed polite shape for giving advice.

Type 3 is the conditional of regret. It's for things that are now impossible because the moment has gone — what didn't happen, but you wish it had. "If she had studied harder, she would have passed" — but she didn't, and the exam is over; nothing can change it. If Type 2 stepped one pace back from reality, Type 3 steps two paces back, all the way into the past, because the door is now shut. Recipe: If + past perfect, would have + V3.

The feeling is always "too late": if only this had happened, that would have followed. The textbook's own example (page 134) is a trader's regret — "if I had got something smaller, I would have exchanged it for honey" — said after the chance was already lost.

• If I had got something smaller, I would have exchanged it for honey. (I didn't — too late.)
• If she had studied harder, she would have passed.
• If the bus had arrived on time, we would not have missed the train.
