Correct my mistakes please.

There is a plan which will be of spending 760 billions dollars/yuan/euros on pollution control in Beijing.

In next 3 years, starting from reduce the release of PM2.5.

(I dont understand, here are differents corrections) 

The plan will start off in 3 years from now and its aim is to reduce the release of PM2.5.

Within the next the 3 years the release of PM2.5 will have started to redeace.

This new plan's aim is to reduce 4 major 4 types of pollution sources, including this includes exhaust release from approximately 5 millions motor vehicles, nearby fuel-burning, sand storm and local construction dust.

There are 85 billions dollars/yuan that will be spend spent on the updating and building of sewage and rubbish equipment.

Besides, the government has invested 30 billions yuan to on reforestation in for the next 3 years.

To improve the environment, the city government (still == do you mean also?) plans to build a number of water-cycle factoryies, and forbid construction illegally  illegal constructions / building illegaly.

In addition to, there is are more severe punishments to for toxic emission.

======================

This is pretty good, there are small mistakes that cant go unnoticed, but you get the message across. 

I personnaly find this topic very interesting. Pollution is our worst and major problem for our modern industrial way of life. That is especially true for China, on which the entire world relies for its manufactured goods, and add on to that the fact that China's population density is a lot stronger than elsewhere. 

Mon premier message

Je suis chinoise, mon nom français est Flora, j'habites à Pékin. J'ai étudié à Rennes en France pendant deux ans, et je suis revenue en Chine en Oct. Il y a / Cela fait maintenant deux mois que je n'ai pas parlé ou lu le français. Je voudrais élever améliorer mon niveau de français. Aidez-moi s'il vous plaît!

Il n'y a vraiment rien comme fautes, bravo. 

[je n'arrive pas a faire les accents sur les 'e']

J'ai demande a mon pere pour qu'il corrige ma correction, et j'ai reappris certaines choses, par exemple, on n'accorde pas le verbe lorsqu'il est precede par avoir: 'j'ai etudie' est juste (moi je croyais qu'il fallait mettre un 'e' a la fin comme tu est une fille); lorsque cest le verbe 'etre' on peut accorder: 'je suis revenue'.

En tout cas, cest moi qui vais avoir besoin de faire des progres en francais. Cependant j'essaierais de t'aider au mieux. 

我看懂了你的课文。但是，他写一点儿错误。

Report about our study of for Occupation Plans （是什么？） of University Students

During our National Day holidays, we did this research by the way of sending questionnaires. We did this research in our college, therefore, students who received our questionnaires were mostly our classmates or our schoolmates. We just asked them to fill out the questionnaires and had a small talk with them.
Here are the analysisanalyses <em>(plural)</em> and conclusions:
According to the questionnaires, we can learned about that most students do not know their occupation plans <em>(do you mean their future careers)</em>. By talking with them we knew discovered that they felt aimless after entering university，as a result, they mostly spent their time （更好说：they spent most of their time...) playing games, going shopping, watching movies even sleeping in dormitory. Eventhough they tried hard to in finding their life goal, they still need some suggestions and guidance. What is more/Moreover/Furthermore, they said that they do not know what they can do after graduating from university，so did they not know the distance between themselves and their dream job.
So, we should take some measures to help our university students, such as arranging classes to guide them on how to plan their life.

We believe that as long as we go to great lengths to do it , we can make it in the end. (这个句一点儿习惯，可是我还看懂了。一位英文本土的人应该知把你的句写对。因为你用一个词语。）

That is all, thank you.
