📝 Tips para entender el primer condicional: Forma afirmativa y negativa

1. En la forma afirmativa, el primer condicional se forma utilizando el presente simple en la cláusula principal y el futuro simple en la subordinada. Por ejemplo: «If it rains, I will stay at home» (Si llueve, me quedaré en casa).

2. Para formar la negativa en el primer condicional, simplemente añade «not» después del auxiliar «will». Por ejemplo: «If he doesn’t study, he won’t pass the exam» (Si no estudia, no aprobará el examen).

3. Recuerda que en la cláusula principal puedes utilizar diferentes pronombres y sustantivos, siempre seguidos del verbo en presente simple. Por ejemplo: «If she leaves early, she misses the bus» (Si se va temprano, pierde el autobús).

4. En la cláusula subordinada, puedes utilizar diferentes verbos en futuro simple, como «will», «shall», «going to», entre otros. Por ejemplo: «If we win the game, we will celebrate» (Si ganamos el partido, celebraremos).

5. Practica utilizando ejemplos, tanto en forma afirmativa como negativa, para familiarizarte con la estructura y el uso del primer condicional. Por ejemplo: «If you don’t eat breakfast, you will feel hungry» (Si no desayunas, tendrás hambre).
