Hola Enyer La primera pregunta... "Are you working?" Significa "Estas trabajando?" Pero el otro "Do you working?" no hace sentido en inglés. Sin embargo, "Do you work" significa "tienes un trabajo?" Espero que esta contesta te ayuda.

correction: "Do you work?" "Do you work?" is a question which has a "yes" or "no" answer. If the person has a job or occupation, the answer is "yes". Otherwise, the answer is "no". It is present tense, so it asks about the present moment. The meaning of "are you working?" is less precise. It can mean many different things depending on context. That's because present participles, like "working", are imprecise words. They work like photographs, like images. They exist outside of time. They move freely between parts of speech: "working" can be a noun, an adjective, or even an adverb. They are one of the most difficult things to master when you are learning English. The most common interpretations of "are you working?" are a) "Do you have a job or occupation?" (the same as "do you work?") b) "Are you working at this very moment (rather than, say, sleeping or eating)?" A less common meaning would be c) "Does your body function normally?" This is a strange thing to say, but quite normal to say if you are talking about, say, your automobile: "Is your car working?" Also, "are you working", in the proper context, can also refer to the future or the past. For example, d) "Are you working tomorrow?" asks if you will be doing your job tomorrow. It means exactly the same as "Will you be working tomorrow?" The future tense is not needed because the word "tomorrow" places the action in the future and the present participle all by itself is timeless. The present participle can even refer to the past. For example, you can say e) "Yesterday, I saw Bill working on his car." Again I emphasize: the participle, all by itself, is timeless.

4) Does it equivalent? also does not mean anything. 'Does' is not a substitute for 'is / are' or any other verb. Notice that 'does' is the only verb in the sentence. But 'does' is an auxiliary verb, not to be used by itself. If you use it by itself, it means 'hacer.'
