Hola :) Hace mucho tiempo que me había introducido. Perdón por mi ausencia después de iniciando aquel "thread". Esto es mi primero de real. Por supuesto, quiero que me corrijan para cualquier error. ¡Indíquenlos!

En fin, tengo alguna tarea. Tengo que escoger una tema en otra clase que estamos estudiando y resumirla en español. Escogí la biología, sobre "aquatic life and marine biology". Aquí lo es...

--Temas acerca de los varios sistemas acuáticos y la vida que los habitan--

El contenido es bueno, como quiero decir "Topics concerning the various aquatic systems and the life that inhabits them". Solicito que comprueben el vocabulario y la gramática.

Lo siento si parece que estoy hablando demasiado, pero siento como necesito practicar más este idioma. En fin, gracias por adelantado.

I've marked what needs fixed in red, but didn't give any hints about what is wrong. If this is needed, please ask.
There are better ways to say some of the things you wrote, and I didn't know what you were trying to say in one part.

Thanks a lot, Rusty. Here's my attempt at corrections (blue for what I had changed, and red for what I was still unsure of and left alone):

I may have removed a couple of words that seemed unnecessary, and I reworded some of my phrasing in two parts. I'd love to get your feedback.

Better!

The verb introducirse doesn't mean 'introduce oneself'. Use presentarse instead.

actual = today, now
Your original choice real means 'royal'. Both choices, as you can see, are false friends. Use 'de verdad' instead. That means 'real'.

The relative pronoun este is stressed on the first syllable, so needs no accent mark. ;) There was a time when an accent mark was included, but this was only to distinguish the pronoun 'éste' from the determiner 'este', both pronounced exactly the same. What you wrote is the present subjunctive form of 'estar'.

Instead of writing 'En fin, tengo una tarea' and the next sentence, it might be just as good to write 'Como tarea, tengo que escoger ...'. Just my :twocents:.

I marked 'estamos estudiando' wrong for two reasons. Since you are talking about your homework assignment, which pertains to only you, you should probably not say 'we' in this spot. In other words, don't change subjects. It's another class that you alone are taking. The other reason is because the present continuous tense should probably not be used here. That tense is overused by English speakers (but only because the textbooks don't teach correct principles). Use the present indicative tense instead.

¡Gracias otra vez!

Okay. Hace mucho tiempo que me había presentado.

Yeah, I mistyped the accent over the second vowel instead of the first. I meant to start with "Éste...". But are you saying I no longer have to distinguish in my writing between éste the pronoun and este the adjective?

Understandable. However, 'como tarea' sounds a bit strange to my ear. I guess it's just Spanish having that different feel to it in regards to how it conveys the message. I still somewhat translate directly from English in my head.

Both reasons make sense. Again, I guess I'm translating from English when I try to express myself. So changing it: '...un tema de otra clase que estudiamos...".

'Estudio' instead of 'estudiamos'. ;)

Haha, of course. Thanks a million :D
