There are spaces also in japanese, but it's hard for me to know where, because in my school they taught me to write without spaces. In computer you should use them, because if you don't, people won't understand you. (happened to me twice with the same person u.u)

(1) Is the sentence"Le pregunto a la muchacha alta:¿Conoce usted a Luisa?" right??But shouldn't it be "Pregunto a la muchacha alta:¿Conoce usted a Luisa?" The translation is: To the tall girl I asked: ¿Do you know Luisa? I asked the tall girl: ¿Do you know Luisa? It's kind of the same, but with "le" you emphasize. (2) What is the meaning of"voy a" in the sentence"Le voy a dar una tarjeta",why not just say"Le doy una tarjeta" "Voy a dar" it's "going to give", and that's future. That means you are planning to do something. I you say "le doy" it means "i give" and that's present. (3) I feel really confused with the"Le".There are there sentences: ①Me gusta nadar ②Te gusta cantar ③A María le gusta bailar. I feel completely confused.Why does the third one has"Le"??Can I try to understand in this way:The dance makes Mary love itself.But then why don't the ① and ② have "Le"??? ①Me gusta nadar: I like to swim. ②Te gusta cantar: You like to dance. ③A María le gusta bailar: María likes to dance. You can change it to she, so it's easier. "She likes to dance" "A ella le gusta bailar". So, "she" is third person. Kind of the "s" at the end of "likes" for "he, she, it". Another thing; you always use "le" before the verb.
