present simple
The present tense is the base form of the verb: I work in London.
But the third person (she/he/it) adds an -s: She works in London.
We use the present tense to talk about:
• something that is true in the present:
I’m nineteen years old.
He lives in London.
I’m a student.
• something that happens again and again in the present:
I play football every weekend.
We use wordslike sometimes, often. always, and never (adverbs of frequency) with the present tense:
I sometimes go to the cinema.
She never plays football.
• something that is always true:
The adult human body contains 206 bones.
Light travels at almost 300,000 kilometres per second.

• something that is fixed in the future.
The school term starts next week.
The train leaves at 1945 this evening.We fly to Paris next week.




Questions and negatives

• With the present tense, we use do and does to make questions. We use does for the third person (she/he/it) and we use do for the others.
We use do anddoes with question words like where, what and why:
