Review and master advanced English grammar structures.
Mastering English Grammar
Have you ever wondered why some people sound more polished and professional when they speak or write in English? The secret often lies in their command of grammar. At VG1 level, you have already learned the basics, but now it is time to refine your understanding and tackle more complex structures that will elevate your English to the next level.
Grammar is not just about following rules - it is about having the tools to express exactly what you mean. When you master advanced grammar, you can communicate subtle differences in meaning, time, and possibility. You can express hypothetical situations, report what others have said, and structure your ideas in sophisticated ways.

One of the most challenging distinctions for Norwegian speakers learning English is the difference between Present Perfect and Past Simple. In Norwegian, we often use the same form for both, but in English, these tenses communicate different meanings.
Present Perfect (have/has + past participle)
The Present Perfect connects the past to the present. Use it when:
1. The action has a connection to now:
- "I have lived here for 5 years" (I still live here now)
- "She has worked at the company since 2020" (She still works there)
2. The time is unspecified or unimportant:
- "I have been to London" (sometime in my life, doesn't matter when)
- "Have you ever tried sushi?" (at any point in your life)
3. Recent events with current relevance:
- "She has broken her leg" (it's still broken now)
- "I have just finished my homework" (I finished moments ago)
4. Actions that may happen again:
- "I have visited Paris three times" (and might visit again)
- "He has won several awards" (and might win more)
Past Simple
The Past Simple describes completed actions with no connection to the present. Use it when:
1. The action is finished at a specific time:
- "I lived in Oslo in 2019" (I don't live there now)
- "She graduated in June" (a completed event)
2. The time is specified:
- "I went to London last year" (specific time mentioned)
- "When did you arrive?" (asking about a specific time)
3. Telling stories or sequences of events:
- "She broke her leg, went to hospital, and got a cast"
- "I woke up, had breakfast, and left for school"
4. Historical facts:
- "Shakespeare wrote Hamlet in 1600"
- "The Vikings invaded England in 793"
Key Signal Words:
| Present Perfect | Past Simple |
|---|---|
| already, yet | yesterday |
| ever, never | last week/month/year |
| recently, lately | in 2020, in June |
| so far, up to now | ago (two days ago) |
| since, for | when I was young |
| just | at that time |
| this week/month/year | that day |
Complete these sentences with the correct tense and explain your choice:
1. I ______ (work) at this company for ten years.
2. I _____ (work) at that company for ten years, but then I left.
3. _____ you ever _____ (try) Norwegian brown cheese?
4. I ______ (try) it when I visited Oslo last summer.
1. I have worked at this company for ten years.
- Present Perfect because the action started in the past and continues to the present
- The person still works there now
- "For ten years" indicates duration up to now
2. I worked at that company for ten years, but then I left.
- Past Simple because the action is completely finished
- "But then I left" shows the situation ended
- The person no longer works there
3. Have you ever tried Norwegian brown cheese?
- Present Perfect because "ever" asks about experience at any time in life
- The specific time doesn't matter
- We're interested in the experience itself, not when it happened
4. I tried it when I visited Oslo last summer.
- Past Simple because we have a specific time: "last summer"
- The action is complete and finished
- Both "tried" and "visited" are in Past Simple because they happened at the same specific time
Common Mistakes to Avoid:
- ❌ "I have seen him yesterday" (specific time = Past Simple)
- ✓ "I saw him yesterday"
- ❌ "Did you ever visit Paris?" (unspecified time = Present Perfect)
- ✓ "Have you ever visited Paris?"
Choose the correct tense (Present Perfect or Past Simple) and explain why:
I (have visited / visited) Paris three times in my life.
She (has moved / moved) to Bergen last month.
We (have not finished / did not finish) the project yet.
The Vikings (have invaded / invaded) England in 793.
I (have known / knew) Maria since we were children.
When (have you arrived / did you arrive)?
Write five sentences about your own life experiences. Use Present Perfect for three sentences and Past Simple for two. Make sure each sentence demonstrates correct usage.
Conditional sentences express what happens (or would happen) under certain conditions. English has several types of conditionals, each expressing different degrees of possibility or reality.
Zero Conditional (General Truths and Facts)
Structure: If + present simple, present simple
Used for: Scientific facts, general truths, things that always happen
Examples:
- "If water reaches 100°C, it boils." (scientific fact)
- "If you mix blue and yellow, you get green." (always true)
- "If I eat too much, I feel sick." (personal general truth)
Note: You can use "when" instead of "if" with no change in meaning for zero conditionals.
First Conditional (Real/Likely Future)
Structure: If + present simple, will + infinitive
Used for: Possible future situations, predictions, promises, threats
Examples:
- "If it rains tomorrow, we will cancel the picnic." (possible situation)
- "If you study hard, you will pass the exam." (prediction/promise)
- "If you touch that, I will tell your mother." (threat/warning)
The condition is possible or likely to happen.
Second Conditional (Unreal/Hypothetical Present or Future)
Structure: If + past simple, would + infinitive
Used for: Imaginary situations, unlikely events, giving advice
Examples:
- "If I won the lottery, I would travel the world." (imaginary - I haven't won)
- "If I were you, I would study harder." (giving advice)
- "If I had more time, I would learn Japanese." (hypothetical - I don't have more time)
Note: Use "were" for all persons in formal English (If I were, If he were, If she were). "Was" is acceptable in informal speech.
Third Conditional (Unreal Past)
Structure: If + past perfect, would have + past participle
Used for: Imagining different past outcomes, expressing regret
Examples:
- "If I had studied harder, I would have passed the exam." (I didn't study hard, so I didn't pass)
- "If she had left earlier, she would have caught the train." (She didn't leave early, so she missed it)
- "If they had known, they would have helped." (They didn't know, so they didn't help)
These sentences describe situations that did NOT happen.
Mixed Conditional (Past Condition, Present Result)
Structure: If + past perfect, would + infinitive
Used for: When a past condition affects a present situation
Examples:
- "If I had learned English as a child, I would speak it fluently now." (I didn't learn it as a child, so I don't speak it fluently now)
- "If she had taken that job, she would be living in London now." (She didn't take the job, so she doesn't live in London)
Summary Table:
| Type | If-clause | Main clause | Use |
|---|---|---|---|
| Zero | present | present | facts, always true |
| First | present | will + inf | likely future |
| Second | past | would + inf | unreal present/future |
| Third | past perfect | would have + pp | unreal past |
| Mixed | past perfect | would + inf | past cause, present effect |
Identify the type of conditional in each sentence and explain the situation:
1. If I had a million dollars, I would buy a house.
2. If you heat water to 100°C, it boils.
3. If she had told me earlier, I would have helped her.
4. If it rains, we will stay inside.
5. If I had studied medicine, I would be a doctor now.
1. "If I had a million dollars, I would buy a house."
- Type: Second Conditional
- Structure: If + past simple (had), would + infinitive (buy)
- Situation: Hypothetical present - I don't have a million dollars, so I'm imagining what I would do if I did. This is an unreal present situation.
2. "If you heat water to 100°C, it boils."
- Type: Zero Conditional
- Structure: If + present simple (heat), present simple (boils)
- Situation: Scientific fact - this always happens. It's a general truth about how the physical world works.
3. "If she had told me earlier, I would have helped her."
- Type: Third Conditional
- Structure: If + past perfect (had told), would have + past participle (helped)
- Situation: Unreal past - She didn't tell me earlier (past), so I didn't help her (past). We're imagining a different past outcome.
4. "If it rains, we will stay inside."
- Type: First Conditional
- Structure: If + present simple (rains), will + infinitive (stay)
- Situation: Real/possible future - It might rain tomorrow, and if it does, we have a plan. The rain is a genuine possibility.
5. "If I had studied medicine, I would be a doctor now."
- Type: Mixed Conditional
- Structure: If + past perfect (had studied), would + infinitive (be)
- Situation: Past decision affecting present - I didn't study medicine in the past, so I'm not a doctor in the present. The past condition has a present result.
Key Recognition Tips:
- Look at the verb forms in both clauses
- Consider whether the situation is real, possible, or imaginary
- Think about the time frame: present, future, or past
Complete these conditional sentences with the correct verb form. Identify which type of conditional each sentence is.
If I (be) _______ you, I would apologize immediately.
If it rains this afternoon, we (cancel) _______ the outdoor event.
If she (study) _______ harder last semester, she would have passed the final exam.
If you heat ice, it (melt) _______.
If I (know) _______ about the meeting, I would have attended.
If he (take) _______ that job in 2020, he would be living in New York now.
Write your own conditional sentences for each situation described:
A scientific fact about what happens when you combine certain chemicals or elements.
A likely plan for if the weather is good this weekend.
Advice to a friend using "If I were you..."
A regret about something you didn't do in the past.
Summary: Key Points from This Chapter
Present Perfect vs Past Simple
- Present Perfect connects past to present: "I have lived here for 5 years"
- Past Simple is for completed past actions: "I lived there in 2019"
- Watch for signal words: "yet," "ever," "since" (Present Perfect) vs "yesterday," "last week," "ago" (Past Simple)
Conditional Sentences
- Zero Conditional: Facts and general truths (If + present, present)
- First Conditional: Real future possibilities (If + present, will + infinitive)
- Second Conditional: Hypothetical present/future (If + past, would + infinitive)
- Third Conditional: Unreal past (If + past perfect, would have + past participle)
- Mixed Conditional: Past condition with present result (If + past perfect, would + infinitive)
Common Errors to Avoid:
- Using Past Simple with unspecified time: ❌ "I visited Paris many times" ✓ "I have visited Paris many times"
- Using Present Perfect with specific past time: ❌ "I have seen him yesterday" ✓ "I saw him yesterday"
- Using "would" in the if-clause: ❌ "If I would have money" ✓ "If I had money"
- Mixing conditional types incorrectly: Be consistent with your time frame
Tips for Mastery:
1. Practice identifying signal words in texts
2. When unsure, ask: "Is this connected to now, or is it finished?"
3. For conditionals, identify whether the situation is real or imaginary first
4. Read extensively to internalize correct patterns
5. Check your own writing specifically for these structures
Comprehensive Exercise: Read this short text and correct all the grammar errors related to tenses and conditionals.
"I have visited my grandmother last weekend. She told me that she has lived in that house since 50 years. If I would have known she was sick, I would visited her earlier. I have promised that if I will have time next month, I will come again. If I was her, I will move to a smaller apartment. She said that she has already considered it when she retired, but she has decided to stay."
Creative Writing Task: Write a short paragraph (100-150 words) about "What would be different if you had made a different choice in the past?" Use at least one example of each: Present Perfect, Past Simple, Second Conditional, Third Conditional, and Mixed Conditional.
