Present simple or present continuous?
Use the present simple for habits and general facts, and am, is or are + verb-ing for an action happening now. Compare: Youssef walks to school every day. Today he is taking the bus. This English 2AC lesson helps you choose a tense from the meaning, build questions and avoid the mistakes that often appear in School day exercises.

Start with the situation
Choose a tense from the situation. Make affirmative, negative and question forms. Explain a correction instead of guessing from one keyword.

What changes between a habit and an action now?
A habit repeats. Every morning, on Mondays and usually can help you recognise it: I read before school. A general fact also uses the simple form: A school library lends books. An action in progress is happening around the moment of speaking: I am reading the last page now. A temporary change can use the continuous too: This week we are studying in another room. The important difference is the situation, rather than how long the action lasts.
Picture a pupil describing two journeys. He usually walks with his cousin, so he says We walk to school. This morning it is raining and they are on a bus, so he says We are taking the bus today. Both statements can be true. The first describes their normal routine; the second describes this particular morning.

How do you build the two tenses?
With I, you, we and they, use the base verb in a simple statement. With he, she or it, add s or the appropriate spelling ending: plays, watches, studies. For negatives and questions, use do or does + the base verb: He does not study art. Does he study English? The s belongs to does, so the following verb stays study.
For the continuous, choose am, is or are from the subject, then add the ing form: I am writing; he is reading; they are sitting. Make a negative by adding not after be. Make a question by moving be before the subject: Are they sitting? Drop the final silent e in writing, and double the last consonant in running. Do not leave out be: He reading is incomplete.
| Purpose | Present simple | Present continuous |
|---|---|---|
| Statement | He reads every day. | He is reading now. |
| Negative | He does not read at break. | He is not reading now. |
| Question | Does he read at break? | Is he reading now? |
A normal day and a change
I usually study in the library. Today the library is closed, so I am studying at home. My brother studies maths on Tuesdays. At the moment he is drawing a map.
- Usually study and studies describe routines. Am studying and is drawing describe the current situations.
Can a time word always tell you the answer?
A time expression is a useful clue, but read the whole sentence. I know the answer now uses the simple because know describes a state here. I like English is natural; I am liking English is not the form to use for an ordinary preference in this exercise. Likewise, every day tells you about repetition, but you must still choose the correct subject and verb form.
When you check your answer, ask three questions. Is this a habit, a state or an action in progress? Which subject controls the verb? Does my question or negative already contain an auxiliary? This small routine prevents both She does not walks and Is she walks. Read the corrected sentence aloud to notice whether it has a complete verb group.
A method you can reuse
Step by step
Work step by step
- Decide whether the situation repeats or is happening now.
- Choose the simple form or be + ing.
- Check the subject and any auxiliary.
- Read the complete sentence to check its meaning.

Remember
After does or does not, use the base verb. For the continuous, keep am, is or are. The forms Does he plays? and He playing are incomplete or incorrect.
