1. Two English perspectives on an action
An activity such as reading can be a habit or an action happening right now. English makes this perspective explicit through the verb form: I read or I am reading. Before choosing, ask yourself: am I describing what I usually do, or what is in progress?
The tenses do not divide actions into important and unimportant, or long and short. The same verb can take either form when the message we want to convey changes.
I read on the train.
I read on the train.
Present Simple describes habitual behaviour. The sentence does not say whether I am holding a book now.
Please wait. I am reading your message.
Please wait. I am reading your message.
Present Continuous presents reading as ongoing: the reply is still to come, but this is not a statement about a habit.
2. Present Simple: a habit or general characteristic
Use Present Simple for a usual routine, repeated action, or general fact. Usually, often, and every Monday can specify frequency, but the habitual perspective is sometimes clear without them.
A general fact about work or where someone lives is not a promise that nothing will ever change. The simple tense merely presents the situation as a fact of life without specifically emphasising its temporary nature.
My sister fixes phones.
My sister fixes phones.
This is a general statement about her work. She is not necessarily fixing a phone at the moment of speaking.
We buy bread on Fridays.
We buy bread on Fridays.
The recurring day describes our usual practice, not a single purchase in progress.
He lives near the park.
He lives near the park.
We state where he lives. This does not imply that he will stay there forever.
3. Present Continuous: a process and a temporary period
Present Continuous can describe an action observable right now. But “now” can be broader: the current week, month, or a temporary job. The action does not have to happen continuously during every second of that period.
A temporary action can be repeated daily. Every day therefore does not rule out Continuous: what matters is whether we present an established habit or a limited current routine.
The children are drawing at the table.
The children are drawing at the table.
We describe a scene in which drawing is in progress.
I am staying with my aunt this week.
I am staying with my aunt this week.
This concerns the current period of accommodation. You can say it while out walking, when you are not physically in your aunt's home.
Only this month, we are practising English every day.
Only this month, we are practising English every day.
Daily repetition is compatible with Continuous because the temporary routine for this month is emphasised.
4. Two constructions: do not mix their parts
In an affirmative Present Simple statement, use the base form, or the -s/-es form after he, she, or it. Present Continuous requires am/is/are and an -ing verb.
In negatives and questions with ordinary verbs, Present Simple uses do/does; the main verb after them has no -s. Present Continuous uses its own am/is/are: do not add do or does. Here, these forms help express the chosen meaning correctly, rather than serving as separate practice of every form.
Habitual: she works / she does not work / does she work? · In progress: she is working / she is not working / is she working?
He does not drive to work. He is not driving now, either.
He does not drive to work. He is not driving now, either.
Does not drive negates the habitual action; is not driving negates the action at the current moment. Preserve both negatives.
Do you work here? Are you working now?
Do you work here? Are you working now?
The first question can concern someone's usual employment; the second concerns their current activity. Do and are belong to different constructions.
5. A present state can still require Simple
In their usual meanings, know, need, and like describe states rather than actions in progress. For these basic statements, we normally use Present Simple even when the state concerns the present moment.
This is neither a rule that every state lasts forever nor a ban on every possible Continuous use of these words. At this level, we practise neutral, ordinary meanings; special meanings and stylistic effects belong to other topics.
I need two pens now.
I need two pens now.
Now specifies the time of the need, but need naturally takes Simple here.
She likes music, but she is reading in silence now.
She likes music, but she is reading in silence now.
Likes expresses a preference; is reading expresses the current action. Liking music does not mean listening to it every moment.
6. Clue words do not replace context
Today, this week, and now help identify the time, but they do not determine the form by themselves. First establish whether the message concerns a habitual fact, a process, a temporary routine, or a state. For example, I know the answer now remains in Simple.
Simple with an action verb can be possible in commentary or a narrative of events. Continuous is natural for an ordinary description of a scene before your eyes; a different genre should not be declared ungrammatical. Similarly, Continuous can refer to a future arrangement, but here we practise present situations.
Look at the window. A bird is sitting there.
Look at the window. A bird is sitting there.
This is an ordinary description of an observed scene, so the speaker chooses Continuous.
The player runs, turns and scores.
The player runs, turns and scores.
In sports commentary, Simple can report actions as they unfold. This marks a limit to the explanation, not a model for the main A1 exercises.
I work at home. / I am working at home this week.
I work at home. / I am working at home this week.
Both sentences are grammatical. The first presents a general fact; the second emphasises the current temporary routine.
7. Combining a habit with a current change
In a short message, you can connect a habit and a current situation with but or state them in separate sentences. If a contrast is required, check not only the verb form but also that both facts are preserved.
Do not invent a reason or outcome. The fact that someone usually walks and it is raining now does not establish that they are taking the bus. Similarly, another person's habit does not give a definite answer about what they are doing right now.
I usually eat in the kitchen, but I am eating on the balcony now.
I usually eat in the kitchen, but I am eating on the balcony now.
There are two known facts: the usual location and the location of the current action. No reason for the change is added.
I do not know what Eva is doing now. She usually studies in the evening.
I do not know what Eva is doing now. She usually studies in the evening.
Knowing a habit does not become knowledge of the current action. Do not know honestly preserves the uncertainty.
Common mistakes
Incorrect:I is carrying a bag.
Correct:I am carrying a bag.
I requires am. Choosing the ongoing perspective correctly does not remove the need for subject–auxiliary agreement.
Incorrect:They are watch a film.
Correct:They are watching a film.
For an action in progress, are must be followed by an -ing form, not the base form watch.
Incorrect:Does she works here?
Correct:Does she work here?
In a Present Simple question, does already marks the third person; do not add a second -s.
Incorrect:He does not wears glasses.
Correct:He does not wear glasses.
After does not, the main verb takes the base form wear.
Incorrect:Are you walk to the station?
Correct:Are you walking to the station?
A question about a current action requires are you walking. Are you walk mixes the Continuous auxiliary with a Simple form.
