Hi. I have been looking for a partner. I'm a native US English speaker.

Today is the day to do the assignment. Specifically/In particular, recording my speaking in English and reading English sentences. Also, I have an English test next week, so I need to study for it. Moreover, I'll study TOEIC. I have a lot to do*.

Is this really that efficacious? Then I'll try it. Because I had experienced hunger, I played up the feeling of hunger in the story. He is still unable to handle very complex situations. Then that would be bad. Since there is a national standard for textbooks, there ought to be a standard for the way to teach them to. I got this nickname because I was thin. New information is defined in relation to the hearer, not to the speaker. This may be illustrated by conversations like the following: A: Have you been able to solve* this chess game? B: Not yet. A: Then why should I be your disciple? To A, the fact that B has never been able to solve this game is clearly new information, since A has just asked whether or not B has ever been able to do so. To B, however, this is old information.

Also, "Viva la Vida" by Coldplay, which is in English despite the title.

I'm not saying it's my favorite song or anything, but "How to Save a Life" by The Fray fits your criteria.

In your sentence, "such" acts as an intensifier, and it's optional. One could have written, "You're asking me to do an impossible thing." That means almost if not exactly the same thing as, "You're asking me to do the impossible." However, I think the latter is what a native speaker would more likely say. That is, a native speaker would more likely say, "You're asking me to do the impossible." However, your sentence is not unnatural. If you choose to phrase it your way, that is acceptable.
