Warm-up

Let's see what comes to mind — no notes, and don't worry about mistakes.

You already know one of today's words. Complete this sentence:

"I have a brother a sister."

SPEAK

Have a go out loud: say two true things about your family or your home, joined with the same little word.

Listen in on this conversation

Ana: Are you coming to the party tonight?

Sam: I want to, but I have to work.

Ana: That's a shame! Maybe next time.

Sam: Yeah — I'm tired anyway, so an early night sounds good.

Look again at what Sam says. Two tiny words join his ideas together: "but" and "so". Before you check: what job do you think each one does?

Check your idea CLICK
"But" joins two ideas that don't match — Sam wants to come, but he can't. It's a small surprise or contrast.
"So" joins a reason to its result — Sam is tired, so he wants an early night. These tiny words are everywhere in everyday talk: they turn short, choppy sentences into one clear idea.
Today: four small words — and, but, because, so — so you can join two ideas and tell longer, clearer stories.

Adding & Surprising: and / but

"And" adds a matching idea. "But" shows a surprise — the opposite of what you expected.

Spot the pattern — adding ideas

Three everyday sentences:

Before you check: do the two ideas in each sentence agree, or disagree?

Check the pattern CLICK
They agree — both ideas fit together with no surprise. And simply adds one more true thing.

Spot the pattern — a surprise

Three more sentences:

What's different about these ones?

Check the pattern CLICK
The two ideas don't match — there's a small surprise or problem. But shows that contrast.
idea 1 + and + idea 2 (the ideas agree)
idea 1 + but + idea 2 (the ideas don't agree — a surprise)

Your turn

1. You finished your homework. You also cleaned your room. Both are true, and there's no surprise.

Tell a friend: "I finished my homework, I cleaned my room."

2. You ordered a pizza. They brought you a burger by mistake — not what you expected.

Tell a friend: "I ordered a pizza, they brought me a burger by mistake."

3. Choose the right word. "She studied all night, ___ she still failed the test."

SPEAK

Say two true things about yourself joined with and (they should match), then two true things joined with but (a surprise or a contrast).

Why? Because!

"Because" gives a reason. It answers the question "Why?"

Spot the pattern

Three everyday reasons:

Before you check: does the reason come before "because" or after it?

Check the pattern CLICK
The reason comes after "because". First you say what happened, then "because" + the reason. "Because" always sits right in front of the reason.
[what happened] + because + [the reason]
"Because" doesn't show surprise, and it doesn't add matching facts — it only ever answers "Why?"

Your turn

1. Someone asks why you called the doctor. The reason: you felt sick.

Answer: "I called the doctor I felt sick."

2. Someone asks why the shop is closed today. The reason: it's a public holiday.

Answer: "The shop is closed today it's a public holiday."

3. Choose the right word. "I'm learning English ___ I want to work abroad."

SPEAK

Say three real reasons for things you did this week: "I ... because ..."

So What Happened? because vs. so

"So" gives a result. It's "because" in the opposite order.

Spot the pattern

Three everyday results:

Compare these with the "because" sentences on the last tab. What changed — the words, or the order?

Check the pattern CLICK
The order flipped. With so, the reason comes first and the result comes after. With because, it's the opposite: the result comes first and the reason comes after.
[the reason] + so + [the result]
[the result] + because + [the reason]
Same meaning, opposite order: "I stayed home because I was tired." = "I was tired, so I stayed home."

Your turn

1. Your alarm didn't ring this morning. Because of that, you were late for work.

Tell a colleague: "My alarm didn't ring this morning, I was late for work."

2. It started to rain. Because of that, you all went inside.

Tell a friend: "It started to rain, we went inside."

3. Which sentence means the same as "The trains were cancelled, so I walked to work"?

SPEAK

Tell a partner about something that happened to you recently (a mistake, a lucky moment, a change of plan). Use so at least once to explain the result.

Your Turn to Talk

Time to use all four words in one real story. You do the talking.

The situation

Think about your day or your weekend — real or invented, it doesn't matter.

Tell the story out loud for one minute. Try to use:

01:00

Now put it in writing

Write a short paragraph (3–5 sentences) about the same day or weekend. Try to use at least three of the four words — the checker will tell you which ones it finds.

Mix It Up

Real life doesn't tell you which word to use. Here everything is mixed — you decide.

Fix the mistakes

Each sentence has the wrong joining word. Rewrite the whole sentence correctly.

1. "I was hungry, but I ate a sandwich."

2. "It was cold, because I wore a coat."

3. "She likes pizza, so she doesn't like mushrooms on it."

4. "He was late and he missed the bus."

Which word fits?

5. "I love animals, ___ I have three cats and a dog."

6. "The bus was full, ___ I decided to walk."

SPEAK

One-minute challenge: describe a small problem from this week (something broke, you missed something, a plan changed) and explain what happened next. Try to use all four words: and, but, because, so.

What Do You Remember?

First, a quick check from before

1. Make this negative: "She like spicy food."

2. Say it out loud: how do you make a question about the past, like asking a friend about their weekend? Give one example question.

Compare with a possible answer CLICK
One possible answer: did + person + the base verb — "Did you go anywhere nice?" or "Did you have a good weekend?"

Now, today's words — fresh sentences, no looking back

3. You tidied the kitchen. You also did the washing. Both true, no surprise.

"I tidied the kitchen I did the washing."

4. You planned a picnic. Then it started to rain — not what you wanted.

"We planned a picnic, it started to rain."

5. Someone asks why you left the party early. The reason: you had a headache.

"I left the party early I had a headache."

6. The shop was closed. Because of that, you all went home.

"The shop was closed, we went home."

Think back

Which practice helped you most today — fixing the mistakes, choosing the right word, or the speaking tasks? Say why you think that one worked for you.

Can you now...?

At the start we said: four small words so you can join two ideas and tell longer, clearer stories. Tick what's true:

Anything you didn't tick — go back to that tab and try the exercises once more. They'll still check your answers.
