Please correction the composition if you are good at English

Some people said that reading is good for our study.
* "Study" should be in plural.

Reading can learn about vocabary, grammar and reading skills.
* You can learn by reading; reading itself does not learn anything since it is simply an action.
* You learn new words or you increase your vocabulary.

However, Hong Kong is a busy city.
* OK, but this does not seem to have any relevance.

The student in Hong Kong always have no time to reading.
* Students in Hong Kong... you need to use the plural here because you are referring to students in general.
* ... have no time to read

So, there are some project to make the student reading in some school.
* some should be followed by a plural noun, if the noun is countable: some projects, some schools
* to make +noun +bare-infinitive verb
* the student... see the explanation in the previous sentence

For example, my school have a reading lesson before the first lesson .
* my school = singular, 3rd person + have ==> has
* The sentence is not logical. If there is a lesson before the first lesson, the "first lesson" cannot be the first lesson. Perhaps you can use the word "session."

We need to reading between the 15 mins.
* need to +infinitive
* "in/during those 15 minutes"

And we would have the Patten to read.
* the Patten?

So, we can read book and newspaper.
* books and newspapers; these are general terms again.

And we reading daily and we can have a hobbit to read.
* develop a habit of reading

So I think this method is quiet well for us.
* OK!

I think if we have the hobbit to read. It would be better than other method.
* You use the word "if" in your sentence and so you should have a comma to join the two sentences.
* ... if we have a reading habit, ...
* "it" in the second sentence refer to "reading habit"; why is it better than the other method? "Habit" itself is not a method.

Meaningwise, the composition is decent. You should pay more attention to your grammar and sentence organization. Good luck!

not bad.
