Units 1-3: Present Continuous and Present Simple — English Grammar in Use

English Grammar in Use — Unit Summary

1. Introduction

Welcome to your journey towards mastering English grammar! In this comprehensive summary, we will dive deep into three foundational units from the renowned English Grammar in Use by Raymond Murphy. These combined units cover two of the most essential tenses in the English language: the Present Continuous and the Present Simple.

Understanding when to describe actions happening right now, compared to things that are generally true, forms the bedrock of clear communication. Whether you are holding a conversation, writing an email, or telling a story, mastering these tenses will make your English sound natural, precise, and polite.

In this guide, we will explore:

• Unit 1: The Present Continuous (I am doing)
• Unit 2: The Present Simple (I do)
• Unit 3: Comparing the Present Continuous and Present Simple

Let’s break down the rules, look at practical examples, and learn how to avoid common mistakes so you can use these tenses with confidence!

2. Unit 1: Present Continuous

Grammar Rule

The Present Continuous (also known as the Present Progressive) is the tense we use to talk about actions and things that are happening right now, at the exact moment of speaking. The action has started, but it has not finished yet. It is currently in progress.

To form the Present Continuous, you need two parts: the present tense of the helping verb “to be” (am, is, or are) followed by the main verb ending in “-ing”.

It is important to note that the Present Continuous is used for temporary situations or things that are changing over time. It gives the feeling that something is happening temporarily, not permanently.

Spelling Rules for the “-ing” Form:

• General Rule: Just add -ing to the base verb (e.g., work → working, play → playing).
• Verbs ending in -e: Drop the -e and add -ing (e.g., make → making, write → writing).
• Verbs ending in a short vowel + consonant: Double the final consonant and add -ing (e.g., sit → sitting, run → running, swim → swimming).
• Verbs ending in -ie: Change the -ie to -y and add -ing (e.g., lie → lying, die → dying).

Form Table

Here is how you form positive sentences, negative sentences, and questions in the Present Continuous tense:

Subject	Positive	Negative	Question
I	am working (‘m working)	am not working (‘m not working)	Am I working?
He / She / It	is working (‘s working)	is not working (isn’t working)	Is she working?
You / We / They	are working (‘re working)	are not working (aren’t working)	Are they working?

Key Examples

Here are some real-life examples illustrating exactly how the Present Continuous is used. Notice how the actions are ongoing at the time of speaking.

Positive Sentences:

• Please be quiet. I am working. (I am in the middle of working right now.)
• Look at Sarah! She is wearing her new brown coat.
• We are building a new house on the edge of town.
• The population of the world is increasing very fast.

Negative Sentences:

• You can turn off the television. I am not watching it.
• The weather is beautiful today. It isn’t raining.
• They aren’t listening to the teacher during the lesson.

Questions:

• Are you enjoying the party?
• Why are you looking at me like that? Is there something on my face?
• What is John doing under the car? Is he fixing it?

When to Use

The Present Continuous is highly versatile. Here are the specific situations where it applies:

Use Case	Example
Actions happening exactly now	I’m reading a really good book at the moment.
Temporary situations	I’m living with some friends until I find my own place.
Changes, trends, and developments	Is your English getting better?
Ongoing projects around the present time	He is studying at university this year.

Common Mistakes

Learners often try to use the Present Simple for things happening right now. Remember to always use the “-ing” form for immediate actions.

❌ I read my book right now. Can I call you back?
✅ I'm reading my book right now. Can I call you back?

❌ Watch out! The car comes!
✅ Watch out! The car is coming!

3. Unit 2: Present Simple

Grammar Rule

The Present Simple is used to talk about things in general. We use it to describe facts, universal truths, habits, and routines. Unlike the Present Continuous, the Present Simple describes actions that happen repeatedly or states that are permanent.

The basic form of the Present Simple is just the base verb (like work, play, eat). However, there is a crucial rule: when the subject is third-person singular (he, she, or it), you must add an ”s” or “es” to the end of the verb.

To form negative sentences and questions, we use the helping verbs “do” and “does”.

Spelling Rules for Third-Person Singular (He/She/It):

• General Rule: Add -s to the base verb (e.g., work → works, read → reads).
• Verbs ending in -s, -sh, -ch, -x, or -o: Add -es (e.g., pass → passes, wash → washes, watch → watches, go → goes, do → does).
• Verbs ending in a consonant + -y: Change the -y to -i and add -es (e.g., study → studies, fly → flies).
• Verbs ending in a vowel + -y: Just add -s (e.g., play → plays, buy → buys).
• Irregular Verbs: The verb have becomes has.

Form Table

Here is the basic grammatical structure for the Present Simple tense:

Subject	Positive	Negative	Question
I / You / We / They	work	do not work (don’t work)	Do you work?
He / She / It	works	does not work (doesn’t work)	Does she work?

Key Examples

Take a look at these examples. They all describe things that are facts, routines, or permanent situations.

Positive Sentences:

• Nurses look after patients in hospitals.
• I usually go away at the weekends.
• The earth goes round the sun.
• My brother works in a large bank in London.

Negative Sentences:

• I don’t like very hot weather. I prefer the cold.
• Rice doesn’t grow in cold climates.
• They don’t travel very often because they are so busy.

Questions:

• What does this word mean?
• Do you play the piano?
• Where do your parents live?

When to Use

Use the Present Simple when you want to convey permanence, frequency, or certainty.

Use Case	Example
General facts and absolute truths	Water boils at 100 degrees Celsius.
Habits and daily routines	I get up at 8 o’clock every morning.
Permanent situations	My parents live in London. They have lived there all their lives.
Making promises or apologizing	I promise I won’t be late. / I apologize for the delay.

Common Mistakes

One of the most frequent errors in English is forgetting the “s” for third-person singular subjects, or using the wrong helping verb for negatives and questions.

❌ He work in a bank.
✅ He works in a bank.

❌ She don't like coffee.
✅ She doesn't like coffee.

❌ Do your father play golf?
✅ Does your father play golf?

4. Unit 3: Comparing Present Continuous and Present Simple

Grammar Rule

Now that we understand both tenses individually, Unit 3 focuses on knowing exactly which one to choose. The primary difference is time and permanence:

• Present Continuous (I am doing): Used for temporary actions that are in progress at the time of speaking. The action is incomplete.
• Present Simple (I do): Used for facts, habits, and permanent situations. Things that happen generally or repeatedly.

The Golden Rule of State Verbs (Stative Verbs): There are certain verbs in English that are almost never used in the continuous form (with “-ing”). These are called state verbs. They describe states of being, thoughts, opinions, senses, and emotions rather than physical actions. Even if the feeling or thought is happening right now, you must use the Present Simple.

For example, you say “I like”, not “I am liking”.

Comparison and Form Table

Here is a side-by-side comparison of the two tenses, along with a list of common state verbs.

Aspect	Present Continuous (am/is/are + -ing)	Present Simple (verb / verb + -s)
Time of Action	Happening at or around the exact time of speaking	In general, all the time, or frequently
Complete/Incomplete	Temporary (the action is incomplete)	Permanent or factual
Example Situation	The water is boiling. Can you turn it off?	Water boils at 100 degrees Celsius.

State Verbs (Do not use in the Continuous Form):

Category	Examples
Opinion & Thought	know, believe, understand, think (opinion), realize, suppose
Emotion & Desire	want, like, love, hate, prefer, need
Senses & Perception	see, hear, smell, taste, seem, sound
Possession & Being	have (possession), belong, consist, contain, depend

Key Examples

Notice the contrast between the temporary continuous actions and the permanent simple actions.

Temporary vs. Permanent Contexts:

• Let’s go out. It isn’t raining now. (Temporary action)
• It doesn’t rain very much in summer here. (General fact)
• I am living with some friends until I find my own place. (Temporary)
• My parents live in London. They have always lived there. (Permanent)

Using State Verbs Properly:

• I’m hungry. I want something to eat. (Even though I want it now, we don’t say “I am wanting”.)
• Do you understand what I mean? (Not “Are you understanding”)
• Anna doesn’t seem very happy right now. (Not “Anna isn’t seeming”)

When to Use

Deciding between these two tenses comes down to analyzing the nature of the action and resolving dual-meaning verbs.

Sometimes verbs have two meanings: one an action, one a state.

Verb	State Meaning (Present Simple)	Action Meaning (Present Continuous)
think	I think it’s a good idea. (Opinion)	I am thinking about what happened. (Considering)
have	We have a large house. (Possession)	We are having dinner right now. (Experiencing/Eating)
see	I see what you mean. (Understand)	I am seeing the doctor tomorrow. (Meeting)
taste/smell	The soup tastes good. (Quality)	The chef is tasting the soup. (Action of trying)

Common Mistakes

When learners confuse the two tenses or use state verbs incorrectly, it often leads to sentences that sound unnatural.

❌ I am knowing the answer.
✅ I know the answer.

❌ Are you believing in ghosts?
✅ Do you believe in ghosts?

❌ My brother is living in Paris, he was born there. 
✅ My brother lives in Paris, he was born there.

📝 Quick Summary

Unit 1: Present Continuous

• Use the Present Continuous (am/is/are + -ing) to discuss actions happening exactly right now or temporary situations.
• Don’t forget: The action is currently in progress and is not finished yet.

Unit 2: Present Simple

• Use the Present Simple for habits, facts, daily routines, and permanent situations.
• Don’t forget: Always add an ‘s’ or ‘es’ to the verb for third-person singular subjects (he, she, it).

Unit 3: Present Continuous vs. Present Simple

• Use the Continuous for temporary actions and the Simple for facts and permanent ones.
• Don’t forget: Avoid using state verbs like ‘know’, ‘want’, ‘like’, and ‘understand’ in the continuous form. Remember to check if a verb has a dual meaning!
