The document discusses conditionals in English. It explains that the first conditional uses the present simple with will or may/can/shall plus the infinitive to express a possible result if a present condition is met. Examples are given such as "If I study hard, I will pass my English exam." The second conditional uses the past simple with would plus the infinitive to talk about an unlikely or imaginary result in the present or future. Examples include "If I had a lot of money, I would travel around the world."

afternoon, we can play tennis.

Sometimes, we use should, could or might instead of would, for example: If I won
a million dollars, I could stop working.
