Hola, Richard: 1 it is necessary for him to come and see me at once es necesario que venga a verme enseguida or es necesario que venga y me vea enseguida Both are correct but the first one sounds better. By the way, "enseguida" is just one word You could add "él"= "que él venga..." if it is not clear who the subject is or if it is out of context. 2 I am looking for somebody who can tell me about that business concerning the train Estoy buscando a alguien que pueda contarme sobre el negocio acerca del tren ¡Perfecto! 3 Do you want me to ask the dentist to see you Quieres que yo le pida al dentista que te vea. "yo" is not mandatory in that sentence, only if you want to emphasize it, like do you want ME to ask the dentist... so it would be better just "¿quieres que le pida al dentista que te vea?". Your subjunctive use is flawless :)

Anoche (por favor, corrige)

Anoche, salí con mi amiga. Fue muy divertido. Primero, fuimos a un espectáculo. Luego, fuimos a un bar. Comimos. Hablamos sobre la noche, nuestra trabajo y bebés (madre sustitutas en particular). Regresé a casa a las 2:30am.

Hola Amanda, en español no se separan tanto las frases con puntos (.) muchas veces es mejor hacerlo con comas si estás hablando del mismo tema. 

"madre sustitutas en particular"= ¿Querías decir "en particular, sobre madres subtitutas"?

Agregué "finalmente" al final para conectar mejor el texto.

Hi Javi, "Some", "all" and "most" are called determiners. It's hard to explain them in percentages because it's relative, but for "all of the people" and "all of them" you can say it is a 100%; for "most of them" and "most of the people" you could say it is from 51% to 99%. Finally, when you say "some of the people" or "some of them" it would be just an amount of the total so it could be anything , probably less than 50%. Remember, when you say "most/all/some of the people" you are talking about (a) general population and you say "most/all/some of them" you are talking about a specific group. I hope this helps you :)

No problem! It means "at that moment", in the past, the speaker thinks a woman is living with a movie producer because in the past she was planning on living with an artist, so he thinks it's the same person. "was then" means she was living with a movie producer in the past. Hope it helps!

Hi Yousef, Since it's a metaphor you could interpret it very differently. It means that a man was looking at another person and the latter could tell there was something meschivious or evil in his look. "The laughter was shining dark": something can not shine dark, it's a contradition, that's why is figurative, you shouldn't take it literally, but it makes you think there's something misterious or even wicked with that man.
