So/ Such… that , too/ (not) enough … to

Understanding how to connect ideas is an important part of speaking and writing in English. In this lesson, we look at two very useful structures: so/such… that and too… to / (not) enough… to. These help you explain reasons, results, and limits in a clear way.

1. SO / SUCH … THAT

We use so and such to talk about a cause, and that to show the result.

👉 Grammar

  • so + adjective + that
    • I’m so tired that I want to sleep right now.
  • such + a/an + adjective + noun + that
    • It was such a good movie that I watched it twice.

👉 When to use SO

Use so before an adjective or adverb.
The people were so friendly that I felt relaxed.

👉 When to use SUCH

Use such before an adjective + noun.
It’s such a beautiful day that I want to go outside.

Examples

  • The problem was so big that I needed help.
  • She has such long hair that everyone notices her.

2. TOO … TO / (NOT) ENOUGH … TO

These structures explain that something is more or less than we want or need.

👉 TOO … TO

Use too + adjective + to + verb
→ shows something is more than you want or a negative result.

It’s too cold to go for a walk.
He was too nervous to speak.

👉 (NOT) ENOUGH … TO

Use:

  • not enough + noun
    There isn’t enough time to finish.
  • adjective + enough
    She isn’t strong enough to lift it.

→ means you don’t have as much as you want.

Third Conditional

For lower levels

1. What is the Third Conditional?

We use the third conditional to talk about imaginary past situations.

Imaginary past situations are things that did NOT happen, but we imagine a different result.

👉 We use it to express regret, relief, or “what could have happened.”

2. Form

If-clauseif + had + past participleif he had studied
Result clausewould have + past participlehe would have passed

Grammar structure:

If + had + past participle, would have + past participle.

*had + past participle = past perfect

Positive Forms

What happened (real past)Imaginary result (third conditional)
She didn’t set an alarm, so she woke up late.If she had set an alarm, she would have woken up on time.
They didn’t bring a map, so they got lost.If they had brought a map, they wouldn’t have gotten lost.
I didn’t study, so I didn’t pass the test.If I had studied, I would have passed the test.

Make Excuses

In everyday life, we sometimes arrive late, forget to do something, or make a small mistake. When this happens, we need to give a clear and polite excuse.
Making excuses helps people understand what happened and why.

This lesson will help you learn useful English expressions to explain situations politely and naturally. 😊

What Does “Make an Excuse” Mean?

To make an excuse means to give a reason for something you didn’t do or for something that went wrong.

Sometimes excuses are real.
Sometimes they are not.
But in English, we often use excuses to explain situations politely.

Examples:

  • “I made an excuse for being late.”
  • “She always makes excuses for not finishing her homework.”

Making excuses is useful in daily life, at school, at work, and with friends.

Here’s a table of useful phrases to help you get started:

Useful Phrases Table

Making ExcusesApologisingAccepting / Rejecting Excuses
Well, you see…I’m really sorry… 😔OK / Never mind. I understand. 😊
I meant to, but…It was very stupid of me. 😣These things happen. 🤷
I had to…I won’t do it again, I promise! 🤞That’s no excuse. ❌

You can combine these sentence starters with a reason.

For example if you are late you can make the following excuses:

Starter PhraseReason (Complete the sentence)
Well, you see……the traffic was terrible. 🚗💨
I meant to, but……I overslept. 😴
I had to……help my sister before leaving. 👧
I had to……go back home to get something. 🏠

Conversation 1 — Being Late

A: You’re late again!
B: Well, you see… the bus was really slow today.
A: You should leave earlier.
B: I know. I meant to, but I couldn’t find my keys.

Conversation 2 — Forgetting Something

A: Did you bring the book I lent you?
B: I meant to, but I left it on my desk at home.
A: You always forget things!
B: I know… I’ll bring it tomorrow.

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.)

🧠 Summary Table

Present Simple Passiveam / is / are + past participleThe room is cleaned every day.Routine / fact

🧭 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

🎯 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.

I use this blog for learning English.

5. FOR + Noun

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:
Use for + noun when you’re not using a verb.

This room is for meetings.
These lessons are for students.

🧠 Summary Table

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.

🧠 Quick Grammar Guide

Time / SituationFormExampleMeaning / Note
Present Abilitycan / can’t + base verbI can cook Italian food.General ability now
am / is / are able to + base verbShe is able to speak three languages.Same meaning as can, more formal
Past Ability (general skill over time)could / couldn’t + base verbI could swim when I was 6.Ability you had in the past
Past Ability (one successful event)was / were able to + base verbI was able to fix my computer yesterday.You actually succeeded in that moment
Future Abilitywill be able to + base verbI will be able to drive next year.Use instead of can for future actions
Ability up to now / Experiencehave / has been able to + base verbI’ve never been able to sing well.Ability from the past until now

✅ Important Notes / Common Mistakes

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

Zero Conditional & First Conditional

Conditional sentences are used to talk about situations and their consequences. In English, different types of conditionals are used depending on whether we are talking about facts that are always true or possible events in the future.

✅ Zero Conditional: Facts and Things That Always Happen

The zero conditional is used for situations that are always true. It shows a cause and effect relationship that does not change.

Examples:

  • If you heat water to 100°C, it boils. 💧
  • If it rains, the ground gets wet. 🌧️
  • If I am tired, I go to bed early. 🛏️

Key points:

  • Used for facts, routines, or general truths.
  • Both parts use the present simple tense.

✅ First Conditional: Real Possibilities in the Future

The first conditional is used for possible events in the future and their likely results. It is often used for predictions, warnings, promises, or advice.

Examples:

  • If it rains tomorrow, we will stay at home. 🌧️🏠
  • If I study hard, I will pass my exam. 📚
  • If she doesn’t hurry, she will miss the bus. 🚌

Key points:

  • Talks about possible future situations.
  • The if-part uses present simple, and the result uses will + base verb.

🔹 Comparing Zero and First Conditional

FeatureZero ConditionalFirst Conditional
MeaningFacts, general truths, things that always happenPossible situations in the future
Tense in if-partPresent simplePresent simple
Tense in result-partPresent simpleWill + base verb
ExampleIf you mix red and blue, you get purple.If it rains tomorrow, we will stay home.

  • Zero conditional = “always true”
  • First conditional = “might happen in the future”

Defining Relative Clauses

When we speak or write in English, we often need to give extra information about a person, a place, or a thing.
For example:

  • I met a woman. She works at the museum.
    I met a woman who works at the museum.

We combine the two sentences using a relative clause.

Defining relative clauses help us identify exactly who or what we are talking about — they define the noun. Without this information, the sentence would be unclear.

What Is a Defining Relative Clause?

A defining relative clause gives essential information about a noun.
It tells us which person, thing, or place we mean.

Without relative clauseWith defining relative clause
The man is my teacher.The man who is wearing a blue jacket is my teacher.
I read the book.I read the book that you recommended.
The café is closed.The café where we had breakfast is closed.

🟢 The information in the relative clause is necessary to understand the sentence.
If we remove it, the meaning changes.

Relative Pronouns

We use relative pronouns to connect the main clause and the relative clause.

Relative PronounRefers toExample
whopeopleShe’s the student who won the prize.
thatpeople / thingsThis is the song that I like.
whichthingsThat’s the laptop which I bought yesterday.
whereplacesThis is the park where I go running.
whosepossession/ relationshipI met a man whose car was stolen.
I met a woman whose husband is an actor.
whentimeDo you remember the day when we met?

🟡 Tip: In defining relative clauses, we don’t use commas because the information is essential.

When Can We Omit the Relative Pronoun?

We can leave out “who,” “which,” or “that” when it’s the object of the clause (not the subject).

The book that I read was interesting.The book I read was interesting.
The teacher teaches English is great. → (cannot omit — “who” is the subject)

We can omitWe cannot omit
The film (that I watched) was amazing.The film that won the award was amazing.
The man (who I met) is from Spain.The man who lives next door is from Spain.

Examples in Context

  • She’s the woman who teaches our English class.
  • That’s the shop where I bought my shoes.
  • He’s the actor whose movies are very popular in Asia.
  • This is the place where we met for the first time.

Each clause gives key information that helps the listener understand exactly who or what we’re talking about.
