Present Continuous: building am/is/are + -ing
1. An action in progress needs two parts in English
Imagine a friend asking what you are doing at this moment. Another language may use a single verb form for waiting, but a complete English Present Continuous sentence needs both am/is/are and an -ing verb. These parts work together: am waiting, is coming, are leaving.
Be marks present tense and agrees with the subject. The -ing verb names the process itself. Waiting on its own can be a conversational fragment, but when a task asks for a complete sentence, write I am waiting or I'm waiting.
Most situations in this lesson happen now so that you can focus on building the form. Now can help express the meaning, but it does not replace am/is/are and is not compulsory in every sentence.
subject + am / is / are + -ing verb
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V-ing / -ing —
- The verb form ending in -ing: working, going. Its role depends on the construction.
I am waiting at the door.
I am waiting at the door.
Am waiting is the complete sequence; at the door only specifies the location.
The bus is coming.
The bus is coming.
The speaker sees the bus moving; is coming describes an action in progress.
2. Find the subject first, then choose be
Use am with I, is with he, she and it, and are with you, we and they. You takes are whether you address one person or several.
A name or one thing can also be the subject: Nina is…, the phone is…. Several people or things need are: Nina and Leo are…, the phones are…. Find the entire subject, not just the word nearest the verb.
When only the subject changes, the -ing form stays the same: I am working → she is working → they are working. Do not add -s to working for he or she.
I → am; he / she / it / one thing → is; you / we / they / plural → are
You are carrying a box.
You are carrying a box.
You still takes are when addressed to one person.
Nina and Leo are cleaning the table.
Nina and Leo are cleaning the table.
The two people together form a plural subject.
The phone is ringing.
The phone is ringing.
One phone can be replaced with it, so use is.
3. Build the whole sequence, not just the ending
If you know the subject and action, make two choices: select am/is/are and form the -ing verb. She + wash gives she is washing. She washing lacks the auxiliary, while she is wash lacks the required -ing form.
Do not put to between be and the -ing verb. In a simple affirmative statement, the subject comes first, then be, then the action. An object and a location follow if the meaning needs them.
Do not invent new facts when correcting the form. If someone is cooking, the correction should not suddenly specify that they are cooking dinner.
she + wash → She is washing.; we + eat → We are eating.
She is washing a plate.
She is washing a plate.
Is and washing are both required; a plate preserves the named object.
We are eating.
We are eating.
The sentence is complete without naming the food: are eating already expresses the action.
4. Some useful -ing forms
Often, simply add -ing: read → reading, wash → washing, wait → waiting. In familiar words ending in silent e, remove it: make → making, write → writing, use → using. This does not mean removing every final e: for example, see → seeing.
In the short words run, sit and swim, double the final consonant before -ing: running, sitting, swimming. Do not apply this to every word ending in a consonant. Final w, x and y are not doubled: snowing, fixing, playing.
In longer words, stress matters: open → opening, but begin → beginning. These are supporting examples, not a complete spelling course. The main aim of this practice is to build be + -ing; check an unfamiliar form in a dictionary if needed.
I am making tea.
I am making tea.
Make loses its final e, and I needs am.
Two men are running.
Two men are running.
The plural subject takes are, and run becomes running with two n letters.
She is opening the window.
She is opening the window.
Opening has no doubled n; check the form of be separately.
5. A contraction does not remove be
In ordinary messages, I am can contract to I'm; you are to you're; we are to we're; and they are to they're. He is, she is and it is become he's, she's and it's. Be does not disappear: part of it remains after the apostrophe.
Full and contracted forms convey the same meaning. Contractions are common in conversation and informal messages; full forms are also correct. If an exercise specifically asks you to contract or expand a form, make that particular change.
The apostrophe matters: we're means we are. Write it inside the contraction without spaces. In She's working, 's means is, but not every 's in English has this meaning.
I'm looking for my bag.
I'm looking for my bag.
I'm looking contains the same two parts as I am looking.
She's taking a photo.
She's taking a photo.
She's expands to she is here; taking stays unchanged.
We're walking home.
We're walking home.
We're retains the auxiliary are required with we.
6. Negatives keep both parts
To say an action is not happening, put not after am/is/are. The verb keeps -ing: I am not driving, she is not driving, they are not driving.
Contractions are possible: I'm not…, she isn't… or she's not…, they aren't… or they're not…. For the neutral pattern taught here, use I'm not with I; amn't occurs in certain regional varieties, but is not practised here. Do and does are unnecessary because auxiliary be is already present.
subject + am / is / are + not + -ing verb
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V-ing / -ing —
- The verb form ending in -ing: working, going. Its role depends on the construction.
I am not driving.
I am not driving at the moment.
Not follows am; driving keeps -ing.
The dog isn't sleeping.
The dog isn't sleeping.
Isn't sleeping = is not sleeping. Negation does not remove is.
They're not leaving.
They're not leaving.
They're not leaving and they aren't leaving are two correct contracted versions.
7. A simple question and short answer
In a neutral direct yes/no question, move am/is/are before the subject. The -ing form stays after the subject: you are listening → Are you listening? Do not add do/does.
To ask what someone is doing, put What before be: What are you doing? You is the subject, are the auxiliary and doing the action.
In a standard short answer, you can omit the -ing verb: Are you listening? — Yes, I am. Do not contract I am to I'm in this positive short answer. No, I'm not allows the contraction because not follows it. The full statement I'm listening is also correct, but is not a short answer in this pattern.
Am / Is / Are + subject + -ing verb?; What + am / is / are + subject + doing?
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V-ing / -ing —
- The verb form ending in -ing: working, going. Its role depends on the construction.
Is your sister working?
Is your sister working now?
Is comes before the subject your sister.
What are they carrying?
What are they carrying?
What asks about the object; they remains the subject after are.
Are you waiting? — Yes, I am.
Are you waiting? — Yes, I am.
When answering about yourself, change you to I and are to am; do not contract final am in the positive short answer.
8. Boundaries and self-checking
Am/is/are alone does not mean Present Continuous. She is a teacher says who she is; she is teaching describes her action. Both are correct, but only the second has be + -ing verb.
Not every thought about the present should become a process. For ordinary meanings of know, need and like, we usually use the Present Simple: I know, I need, I like. This is not an absolute ban on -ing for every meaning of a word: I think expresses an opinion, whereas I'm thinking can describe the process of considering. Likewise, I have a bike expresses possession, while I'm having lunch describes an action happening now.
The Present Continuous can also describe temporary activity during the current period or an arranged future plan. Those uses are not separate targets here. First learn to build the form reliably for a clear current action.
Before answering, check who performs the action, whether am/is/are fits, whether -ing is present, and whether not or question order is needed. In open tasks, the model is just one possible version. Compare your answer with the meaning and criteria, allowing other natural wording.
She is a teacher. She is teaching a class.
She is a teacher. She is teaching a class.
The first is links the person to a profession; the second is forms part of is teaching.
I know the answer. I am writing it down.
I know the answer. I am writing it down.
Knowing is a state, and writing is a current action; there is no need to force both into the same form.
I'm thinking about your question.
I'm thinking about your question.
Thinking names a process here, not simply the presence of an opinion.
Common mistakes
Incorrect:I is cleaning my shoes.
Correct:I am cleaning my shoes.
I needs am. Change only be, not the action or object.
Incorrect:They waiting for the bus.
Correct:They are waiting for the bus.
The complete standard sentence lacks are before waiting.
Incorrect:She is wash a cup.
Correct:She is washing a cup.
After is in this construction, use the -ing form washing, not the base form wash.
Incorrect:She are cooking.
Correct:She is cooking.
She needs is. Do not add a type of food that is absent from the original sentence.
Incorrect:We are not clean the kitchen.
Correct:We are not cleaning the kitchen.
Not negates the action but does not change the requirement for an -ing verb.
Incorrect:Does he is carrying a bag?
Correct:Is he carrying a bag?
For the direct question, move is before he; does is unnecessary.
