El Verbo "To Be" - Tu Herramienta Básica en Inglés

¿Sabías que el verbo "to be" aparece en casi todas las conversaciones en inglés? Es como el martillo en una caja de herramientas: simple pero indispensable.

En presente simple, este verbo tiene tres formas principales: am (solo para "I"), is (para he, she, it) y are (para we, you, they). Por ejemplo: "I am happy", "She is hungry", "They are students".

Para las oraciones negativas, simplemente agregas "not": "I am not sad", "He is not at home", "We are not late". También puedes usar contracciones como isn't, aren't o 'm not para sonar más natural.

Las preguntas se forman invirtiendo el orden: "Are they happy?", "Is she rich?". Las respuestas cortas son súper útiles: "Yes, they are" o "No, she isn't".

Tip clave: Memoriza las contracciones porque los hablantes nativos las usan todo el tiempo en conversaciones casuales.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
