English is a crazy language. Let’s talk about the grammar rule of articling. It does not make sense whatsoever. Assuming someone asks you to got on car. You already know which car it is. You will not get on wrong car. Thus, the proper English would be in the car.
What if someone asks you to eat apple. You would not begin to finish bowl of apple. Now, let’s not make people confuse. Please have an apple from the bowl. The whole sentence is funny for me. English speaking people get confused easily.
Now, this is the part which does not make sense. The alarm went off; it is not same as saying turn off the light. Saying the alarm went off, it means the alarm is on. Now, let’s work on the “on.” If you are on it, it means you are on top of it. You get on the bus. It does not say that you are on the roof of the bus, it means you are actually in the bus. Now, you sit in the chair.
Good luck learning the English language, you got my point. The English language developed by people who had no clue about language.
