Passive Voice (present and past)

💡 What is the Passive Voice?

We use the passive voice when the action is more important than who does it.

➡️ The focus is on the object (the thing that receives the action), not on the subject (the person who does it).

🔹 Compare:

ActivePassive
The chef cooks the meal.The meal is cooked by the chef.
Someone cleaned the classroom.The classroom was cleaned.

👉 In the active voice, the subject (“the chef”) does the action.
👉 In the passive voice, the subject (“the meal”) receives the action.

🔹 How to Form the Passive

🧱 Structure

Passive = be (am / is / are / was / were) + past participle (V3)

TenseStructureExample
Present simpleam / is / are + past participleThe house is cleaned every day.
Past simplewas / were + past participleThe house was cleaned yesterday.

🔹 1. Present Simple Passive

We use it to talk about things that happen regularly or are generally true.

StructureExampleMeaning
am / is / are + past participleEnglish is spoken in many countries.(People speak English in many countries.)
are madeCars are made in Japan.(Factories make cars in Japan.)

🧠 Tip:
Use the present passive to describe facts, routines, or processes.

🔹 2. Past Simple Passive

We use it to talk about completed actions in the past, when we don’t know or don’t want to say who did the action.

StructureExampleMeaning
was / were + past participleThe phone was invented by Alexander Graham Bell.(He invented it in the past.)
were builtThese houses were built in 1990.(Someone built them, but we don’t say who.)

🧠 Tip:
Use the past passive to talk about inventions, discoveries, or historical facts.

🔹 3. Who Did the Action? (Using “by”)

If you want to say who did the action, use by + person.

ExampleMeaning
This photo was taken by my friend.My friend took this photo.
The book was written by J.K. Rowling.J.K. Rowling wrote the book.

You can also omit “by” when it’s not important:

The window was broken. (We don’t know who did it.)

🧭 Modal Verbs: Obligation and Necessity

💡 What Are “Obligation” and “Necessity”?

We use modal verbs like must, have to, need to, and their negatives to talk about things that are necessary or not necessary. For example, rules, duties, or responsibilities.
We can also use them to talk about permission in the present or past.

🔹 1. Obligation in the Present

We use must, have to, and need to when something is necessary or important to do.

StructureExampleMeaning
must + base verbI must finish this project today.Strong personal obligation
have to + base verbI have to work on Saturday.External rule or schedule
need to + base verbYou need to wear a helmet.It’s necessary or required

🧠 Tip:

  • must = personal obligation (you feel it)
  • have to = external obligation (someone else decides it)

I must study more. (I want to)
I have to study more. (My teacher said so)

🔹 2. NO Necessity in the Present

We use don’t have to or don’t need to when something is not necessary.

StructureExampleMeaning
don’t have to + base verbYou don’t have to come if you’re busy.It’s optional
don’t need to + base verbShe doesn’t need to wear a uniform.It’s not required

🧠 Note:
They mean the same, but don’t have to is more common in everyday English.

🔹 3. Prohibition (Something Is Not Allowed)

We use mustn’t (must not) to talk about rules or strong advice — when something is not allowed.

StructureExampleMeaning
mustn’t + base verbYou mustn’t park here.It’s forbidden
be not allowed to + base formYou are not allowed to park here.No permission

🧠 Tip:
❌ Don’t confuse mustn’t (not allowed) with don’t have to (not necessary).

You mustn’t smoke here. → It’s against the rules.
You don’t have to smoke. → It’s your choice.

🔹 4. Obligation and Necessity in the Past

We can’t use must for the past. Instead, we use had to or needed to.

StructureExampleMeaning
had to + base verbI had to finish my homework last night.It was necessary in the past
needed to + base verbWe needed to buy tickets early.It was necessary

For the negative, we use didn’t have to or didn’t need to (something was not necessary).

We didn’t have to go to school yesterday.
She didn’t need to call — I was already there.

🔹 5. Permission (Present and Past)

We can use be allowed to or could to talk about permission.

TimeStructureExampleMeaning
Presentam / is / are allowed to/canStudents are allowed to use phones at break.
Students can use their phones at break.
It’s permitted now
Pastwas / were allowed toWe were allowed to stay up late.It was permitted
Past (general ability)couldWhen I was a child, I could go out alone.I had permission

🕐 Past Continuous

💡 What Is the Past Continuous?

We use the past continuous to describe actions that were in progress at a specific time in the past.
It helps us talk about what was happening around a moment, or when another action interrupted it.

🔹 FORM

We make the past continuous with was / were + verb-ing.

Subjectwas / wereVerb + -ingExample
I / he / she / itwasverb + -ingI was watching TV.
you / we / theywereverb + -ingThey were studying English.

🧠 Tip: Add -ing to the base verb.
✅ play → playing
✅ write → writing
✅ dance → dancing

🔹 USE 1: Action in Progress in the Past

We use the past continuous for something that was happening at a specific time in the past.

I was working abroad in 2016.
We were visiting friends last night.

🕓 The action was not finished at that moment, it was continuing.

🔹 USE 2: Interrupted Action

We often use the past continuous and past simple together.

🧩 The past continuous = longer action (in progress)
🧩 The past simple = shorter action (interrupted it)

Past Continuous (long)+ when +Past Simple (short)
I was cooking dinnerwhenmy friend called.
They were watching TVwhenthe phone rang.

🧠 Tip: Use when before the short action (past simple).

🔹 USE 3: Two Actions Happening at the Same Time

We use while when two long actions were happening at the same time in the past.

while + Past Continuous,Past Continuous
We were studyingwhileour parents were watching TV.
She was cookingwhilehe was cleaning the kitchen.

🧠 Tip:
Use while to show parallel actions, both were in progress at the same time.

Example: While I was reading, my sister was listening to music.

🔹 USE 4: When vs. While

WordUsed beforeExample
whenpast simple (short action)I was driving when it started to rain.
whilepast continuous (long action)She was singing while I was playing the guitar.

🧩 Compare: Past Simple vs. Past Continuous

MeaningPast SimplePast Continuous
Completed actionI watched TV yesterday.
Action in progress (background)I was watching TV when the phone rang.
Two simultaneous actionsI was reading while she was cooking.

Past Continuous is also known as Past Progressive

Linking Ideas: Because, So, and To

We often need to explain reasons and results in English.
Let’s learn how to use because, so, and to to connect ideas clearly.

1. BECAUSE — to give a reason

We use because to explain why something happens.
It connects a result and a reason in one sentence.

StructureExample
result + because + reasonI stayed home because I was tired.
result + because + subject + verbShe’s happy because she passed her exam.

🧠 Tip:
Use because to answer “Why?”

❓ Why did you stay home?
💬 I stayed home because I was tired.

2. SO — to show a result

We use so to talk about what happened as a result of something.

StructureExample
reason + so + resultIt was cold, so we stayed inside.
subject + verb + so + subject + verbI was hungry, so I made a sandwich.

🧠 Tip:
Use so to answer “What happened?”

❓ It was raining. What did you do?
💬 It was raining, so we stayed home.

3. TO — to talk about purpose (why we do something)

We use to + base verb to say why someone does something — their goal or purpose.

StructureExample
verb + to + base verbI went to the shop to buy some bread.
verb + to + base verbShe’s studying English to travel abroad.

🧠 Tip:
Use to when the second action shows the reason for the first.

❓ Why did you go to the shop?
💬 I went to the shop to buy milk.

🎯 Expressing Purpose

We often want to say why we do something, our goal or reason.
There are several ways to express purpose in English.
Let’s learn and compare them!

1. TO + Base Form

We use to + base verb to show purpose, the reason for an action.

StructureExampleMeaning
verb + to + base verbI study hard to pass the exam.I study for this reason.
verb + to + base verbShe went to the gym to get stronger.She went there with a goal.

🧠 Tip: Use this for short, direct purposes.

I’m calling to ask a question.
He moved to Canada to find a job.

2. IN ORDER TO + Base Form

We use in order to when we want to sound more formal or emphasize the purpose.
It means the same as to, but it’s a bit stronger.

StructureExampleMeaning
verb + in order to + base verbShe left early in order to catch the train.She left early so she could catch it.
verb + in order not to + base verbHe spoke quietly in order not to wake the baby.He didn’t want to wake the baby.

🧠 Tip: Use in order to in writing or formal speech.

I’m taking this course in order to improve my skills.

3. SO (THAT) + Subject + Modal + Verb

We use so (that) to explain the purpose of an action, especially when there is a different subject.
It’s often followed by can / could / will / would / may / might / should.

StructureExampleMeaning
so (that) + subject + modal + verbI’m studying so (that) I can pass my exam.My goal is to pass.
so (that) + subject + modal + verbShe left early so that she could catch the bus.She left early to catch it.

🧠 Tip:
You can say so that or just so in informal English.

4. FOR + Gerund (-ing)

We use for + -ing to say the general use or purpose of something.
It answers “What is this used for?”

StructureExampleMeaning
for + verb-ingThis brush is for painting.The brush is used to paint.
for + verb-ingThese shoes are for running.They’re made for that.

🧠 Tip:
Don’t say ❌ for to — just for + -ing.

We also use for + noun to show purpose, especially with things.

StructureExampleMeaning
for + nounThis medicine is for headaches.You take it when you have a headache.
for + nounThe bag is for my laptop.The bag’s purpose is to carry it.

🧠 Tip:

Be able to

In English, we use different grammar forms to talk about ability.

Ability means what someone can do.
It shows a person’s skill, power, or possibility to do something.

Many students are familiar with can and could to talk about ability, but these two forms are not always enough. For example:

  • We don’t use can to talk about the future.
  • We don’t use could for a single successful action in the past.
  • Sometimes we need a form that shows ability over a longer period of time.

In this lesson, you’ll learn different alternatives and practice choosing the correct one depending on the time (present, past, future) and the situation.

Let’s see the difference 👇

1. Present Ability

FormStructureExampleMeaning
General ability nowcan / can’t + base verbI can cook Italian food.I have this ability now.
More formal / less commonam / is / are able to + base verbShe is able to speak three languages.Same meaning as can, more formal.

2. Past Ability

General ability in the past

FormStructureExampleMeaning
Past ability over timecould / couldn’t + base verbI could swim when I was 6.A skill you had in the past, not just one moment.

Ability in one specific past situation (successful action)

FormStructureExampleMeaning
One event in the pastwas / were able to + base verbI was able to fix my computer yesterday.You succeeded in that moment.

Important:
We use was/were able to (not could) for one completed event in the past.

I was able to call her before the meeting.
I could call her before the meeting. (not clear if I really did it)

3. Future Ability

FormStructureExample
Future abilitywill be able to + base verbI will be able to drive next year.

Common error:
Next year I can speak Japanese.
Next year I will be able to speak Japanese.

4. Ability in Your Life (up to now)

FormStructureExample
Experiencehave / has been able to + base verbI’ve never been able to sing well.

Used to talk about ability from the past until now.

📅 Present Continuous for Future Arrangements

Many students know the present continuous for actions happening now:

I’m studying English right now.

But we also use it to talk about future plans, when something is already decided or arranged.

Let’s see the difference 👇

Present Continuous – Actions Happening Now

We use the present continuous to talk about things that are in progress at this moment.

Structure:
Subject + be (am / is / are) + verb-ing

Examples:

  • I’m reading this blog right now.
  • She’s studying for her test at the moment.
  • They’re having lunch today.

Think:

“It’s happening right now. I can see it or it’s in progress.”

Time words: now, right now, at the moment, today

Present Continuous – Future Arrangements

We also use the present continuous to talk about the future, but only for fixed plans.
These are things that are already organized with a time, place, or person.

Structure:
Subject + be (am / is / are) + verb-ing

Examples:

  • I’m meeting my friend tomorrow.
  • She’s seeing the dentist on Friday.
  • We’re flying to Toronto next week.

Think:

“It’s in my calendar = it’s arranged.”

Time words: tomorrow, next week, on Friday, this weekend

Compare: “Now” vs. “Future Plan”

SituationExampleFormMeaning
Action happening nowI’m studying English right now.am / is / are + verb-ingIn progress at this moment
Future arrangementI’m studying English tomorrow morning.am / is / are + verb-ingFixed plan (already decided)

Tip:
If you use a future time word, people know you’re talking about a plan, not something happening now.

Remember

UseTime WordsExampleMeaning
Action happening nownow, at the moment, todayI’m watching TV right now.Current action
Future arrangementtomorrow, next week, on FridayI’m watching a movie tomorrow.Fixed plan

If you can put it on your calendar 📅 → use present continuous for arrangements.
If you can see it happening right now 👀 → it’s present continuous for actions.

Second Conditional: Grammar Review

What You MUST Know Before Using the Second Conditional

To use the second conditional correctly and confidently, you need to be comfortable with past simple form. The if-clause always uses the past simple, even though we’re talking about an unreal present or future situation.

Here’s a quick review of the essential conjugations:

1. Past Simple – Regular Verbs

Base VerbPast SimpleExample
workworkedIf I worked from home, I’d be happier.
playplayedIf she played an instrument, she’d join a band.
wantwantedIf they wanted a pet, they would adopt one.

📌 Rule: + –ed (or –d after e)

2. Past Simple – Irregular Verbs

(These forms must be memorized—no “–ed” rule!)

Base VerbPast SimpleExample
gowentIf I went to Japan, I’d eat sushi every day.
havehadIf he had more time, he’d read more books.
seesawIf we saw a ghost, we’d run away.
taketookIf she took the job, she’d move to Toronto.

📌 Tip: Students should review the Top 20–30 irregular verbs to feel confident.

3. Past Simple – Negative Form

StructureExample
didn’t + base verbIf I didn’t have online classes, I’d sleep longer.
If he didn’t live in a busy city, he’d have less stress.

📌 Use didn’t + base verb (NOT “didn’t went / didn’t saw”).

4. Verb BE in Unreal Conditionals

“were” for ALL subjects

❗️Verb Be
Simple past REAL
✅ Verb Be
Preferred in Second Conditional
I was If I were
He/ She/ It wasIf he/she/ it were*
You/ We/ They wereIf you/ we/ they were

📌 In second conditional, “were” is used with I / he / she / it (not just “you / we / they”).
“If I were…” is more natural in written and formal English.

*NOTE: with he, she and it we can use was (instead of were) in informal speaking.

Example: If she was here, she’d know what to do

🔮Future with I think… will

We use will to talk about what we believe or expect will happen in the future.
Predictions are our ideas or opinions about the future, not facts.

How to Make Predictions

Use: will + base form of the verb

Examples:

  • It’ll be more difficult to find a good job.
  • We’ll travel more in the future.

We often add I think to show it’s our personal opinion:

  • I think we’ll be healthier.
  • I think people will live longer.

🗣️ In spoken English, will is usually shortened to ’ll.

I think we’ll have robots at home.

❌ How to Make Negative Predictions

To say something won’t happen, use won’t (= will not).

  • In the future, we won’t have so many problems.

You can also say I don’t think + will:

  • I don’t think we’ll work as much.
  • I don’t think it’ll rain tomorrow.

🧠 Quick Grammar Guide

Structure / QuestionExampleUse / Meaning
will + base verbWe’ll study online.To say something will happen in the future
won’t + base verbWe won’t drive petrol cars.To say something won’t happen in the future
I think + will + base verbI think people will live longer.To give your opinion about the future
I don’t think + will + base verbI don’t think it’ll rain.To give a negative opinion about the future
Do you think …? → Short answersDo you think it will rain tomorrow?✅ Positive: I think so. / I hope so.
❌ Negative: I don’t think so. / I hope not.
Meaning of short answersI think so → I believe it will happen
I don’t think so → I believe it won’t happen
I hope so → I want it to happen
I hope not → I don’t want it to happen

💡 Tip:

  • Use “I think so” / “I don’t think so” to give your opinion.
  • Use “I hope so” / “I hope not” to express your wish.
  • These short answers are easy to use with any question starting with Do you think …?
