Help please it's really important

So for school I have to make a text, please correct my mistakes thx :) Please it's really important.

1/ A Mobile
A long time ago it was only used to call, it was unmoving.
Nowadays it is used to call, send text messages and do many other things.  It's portable.
In the future, it may change shape according to the situation. It might become a watch or a bulb. it will depend.

2/ A TV
In the old days it was a simple tv which projected images.
Now we have 3D TV. With it, we can have the feeling of being in the movie, while just being passive.
In the future, we could have the feeling of really be a part of the movie. We'll feel the actions and everything.

3/ An Mp3 player
Back in the past it was a record player which needed a CD, it was massive.
Then the mp3 player taken place, it has the same role but it's more little and it doesn't need a CD, but it needs a headphone.

4/ A GPS
A few years ago it was a map
Now it's digital
Later, it could bring the car directly to the desired place. 

Thanks a lottttt

Votre information au sujet des MP3 Players n'a pas raison. <<http://www.recovercamcorder.com/images/recover-deleted-files-from-mp3-music-player.jpg>> est un photo d'un MP3.  Au present, beacoup de gens n'utilisent pas les MP3.  Les iPods sont plus populaires.

Vos phrases sont tres longues.  En anglais, on n'utilise pas les phrases si longues.  Cela n'a pas d'importance quand on parle, mais en ecrivant, c'est tres important.  Votre vocabulaire est tres impressionant.  Bon travail!

(Je suis desolee si le francais n'est pas bon)

First part: text about literature

Hello! Here is a text I wrote about literature! I hope there aren’t too many mistakes!
We have to wonder about the following question: why and how can we say that an author is present in his texts as an “I” and that he has an “eye” for writing?
First of all, the poet uses his writing skills to speak about himself and his story. He uses stylistic devices such as metaphors, meaning that he removes a thing from its first identity by using another name to speak about it, in order to create a picture. The author can use it to speak about himself without clearly saying that he is the character (by because of bashfulness, maybe) or it’s even a way to give his text a poetic quality. In the case of William Butler Yeats’ poem “The Cat and the Moon” for example, the author tells the story of a cat connected to the moon, which is actually being the metaphor for of his relationship with the women he loves. In that case, the metaphor is even a personification. This use of the stylistic devices allows him to speak about his feelings.
There’s something else about the author talking about himself: he actually tells us who he is in the way he tells the story: For example Arthur C. Clarke uses a very precise scientific vocabulary in his science fiction stories: he was himself very fond of sciences and was a part of a scientific review for example, also he helped some scientific projects such as the invention of the satellites and others...

Très bon travail!  Votre phrases sont très longues; en anglais, on n'utilise pas souvent des phrases longues.  Mais vous écrivent plus bien que beaucoup des étudiants américains (je suis étudiante dans les États-Unis, et il y a des étudiants de ma classe d'anglais qui ne peuvent pas écrire aussi bien que vous).  

My dream house

For those who are wealthy, buying a sophisticated house is not an issue. However, most people must deal with their own shabby flats in the city. But have you ever considered a little cottage surrounded by nature? Actually, that is my only dream house.

To begin with, I cannot abide disturbing noises from the city. All I need is to look through a window and gape at a breath-taking landscape ablaze with greenness and serenity. Moreover, it must be small, for a gargantuan house can fill my mind with confusion. Besides, I would not like to be troubled with any neighbors. The only person I want to remain beside me is my lover since any house in her company becomes wonderful.

I would decorate it with my paintings as it is to contain every single piece of my essence. Furthermore, the ceiling and the walls must be painted with a cerulean blue combined with pure white color. Any other color can shake my emotions with alacrity because of my extreme sensibility. Lastly, since I love animals, I would like to be welcomed when entering into the house by hundreds of birds flying freely over the furniture and above my head.

To sum up, what I need is a small house away from any city so as to devote my entire life in love, serenity and devotion. As John Lennon said: “All you need is love”, and you are allowed to say I am too romantic and idealistic, but leave me alone with my house.

It's very good! Your vocabulary is great.  I know native English speakers who don't know all those words.
