Travel

Think about the last time you got somewhere — the walk to school, a bus to town, a train up the hill. Now stretch that idea out: the same human itch to move took us from a stone roller dragged through mud in 3500 BC all the way to a Boeing slicing through clouds at 900 km/h. Travel is one long story, and this unit puts you inside it.

Here's the thing, though — under all the talk of trains and trams, this unit is quietly teaching you two of the most-tested pieces of grammar on the O/L paper. When you narrate a journey ("we caught the train, we climbed the rock"), you're practising the past simple. When you describe an event in progress ("the food is being served, the hall is being decorated"), you're practising the passive voice. Learn to travel in words and you've learned the grammar by accident.

By the end you'll name almost any kind of transport, write a clear itinerary, narrate a trip in clean past simple, describe a busy event in the passive, build new words with suffixes (happy → happiness), and untangle the three different sounds the letters ch can make.

Notice the neat trick the friends use to explain a hard word: they break it apart. "Mono means single" — so a monorail is a train on a single rail. That's a habit worth stealing in the exam. When you meet a long word you half-know, look for the small piece inside it (mono-, bi-, tele-, auto-) and you can often guess the meaning. The same dialogue also does what good explainers do: it gives a definition and an everyday picture ("a vehicle that runs on electricity… on rails built on roads").

Don't try to swallow this list flat. The easy way to hold it in your head is to ask one question of every vehicle: where does it move — on land, in the air, or on water? Sort it into that drawer and the word stays put. A drone and a hot-air balloon feel unrelated until you notice they share the sky; a ferry and a submarine feel different until you notice they share the water. Group by where it travels, and a long list becomes four short ones.

When you tell someone what you did on a trip, every verb has to step back in time. "We wake up early" becomes "we woke up early"; "we catch the train" becomes "we caught the train". That backward step is the past simple, and it is the natural tense of every story you tell about yesterday.

Most verbs make the step the easy way — they just slip on an -ed coat (walk → walked, travel → travelled, visit → visited). But a stubborn handful refuse the coat and change shape entirely, and these are exactly the ones the exam loves to catch you on: go → went, see → saw, take → took, buy → bought, eat → ate, fly → flew, drive → drove, ride → rode, leave → left, come → came. There's no rule for these — they just have to be learned, like faces.

A good travel story isn't just past-tense verbs, though; it's past-tense verbs in order. Sequencing words are the thread that beads them together:

• First, we woke up early and packed our bags.
• Then, we drove to the railway station.
• After that, we caught the 6.30 train to Kandy.
• Later, we walked up to the Temple of the Tooth.
• Finally, we returned home tired but very happy.

Now the slip that quietly costs students marks every year. Once "did" or "didn't" enters a sentence, it has already carried the past tense — so the next verb must relax back to its plain form. A student writes "I didn't went" and feels it's extra-past, extra-correct; it's actually double-tensed and wrong. The "did" already did the job.

Walk into a hotel an hour before a wedding and listen to how staff talk: "the food is being served", "the hall is being decorated", "the chairs are being arranged". Notice what's missing — nobody says who is doing it. That's the passive voice: it spins the sentence around so the spotlight falls on the thing being done, not the person doing it.

Why would you ever hide the doer? Because often the doer doesn't matter — the guest cares that the food is arriving, not which waiter carried it. Think of the passive as a camera that turns away from the worker and zooms in on the work. Compare the two angles:

• Active: Workers are unloading the goods.
  Passive: The goods are being unloaded (by the workers).
• Active: The waiter is serving the food.
  Passive: The food is being served.
• Active: The staff is decorating the hall.
  Passive: The hall is being decorated.

The build is always the same three blocks: take is or are, add being, then the past participle (the V3 form — served, cleaned, arranged). One thing → is being; many things → are being. To ask a question, just lift the is/are to the front: "Is the food being served?"

A suffix is a small tail you bolt onto the end of a word, and that little tail can completely change the word's job. "Kind" is a quality you have; bolt on -ness and "kindness" becomes a thing you can give. The word didn't change its meaning — it changed its role in the sentence, the way the same person can be a player in one game and a referee in another.

This matters in the exam for a sneaky reason. A comprehension passage will use "kindness" when the only word you studied was "kind", or "development" when you knew "develop" — and if you can spot the base word under the tail, you understand the whole sentence. Learn the common tails and you read a third more vocabulary than you "know".

"ch" looks like one sound, but English actually hides three behind it, and the reason is history — words arrived in English from different languages and kept their old pronunciation. So "ch" can hiss like chair, soften to a "sh" like chef, or harden to a "k" like character. The good news: the word\'s origin usually tells you which.
