<span>El contador termina su tercer año de estudios.</span>
It all sounds good but you have to tweak a few sentences. For example in the second sentence and third sentence divide it into two because it sounds like a run on sentence. Instead write "He conocido a Miguel durante dos años. El es muy trabajador y distfruta haciendo música. Ha trabajado en IHOP desde hace casi tres años. A el le encanta ver las sonrisas en la cara de la gente cuando cocina para ellos."
I can give you help for number 2. Not that i don't know the rest but it's best that you learn by what you can do. The example they give you for part B (la obra fue larga) means, the work was long. They give you an image to show people working. For the others, they give you an idea on what to write, so they can be just about anything, so there's no right or wrong. I'll give you an example for number 2; they show you books. It could be words that are hard or HW. For example: La tarea fue dificil. If there is any other you are still stumped on, let me know so i can help.
You could say, “pardon, por favor.”
This means “pardon, please.” You may use this phrase in a crowded area, as you are trying to get through people.
Hope this helps :)
