grammar mistakes

the relugar mistakes that my classmates and I have, are grammar mistakes. i think grammar is about rules which we dont manage well so we commmit this faults. also I believe that some others classmates have problems in punctuation. they use lots of commas and dots. But we already know that in english most of the sentences are separated in ideas by a dot not with millions of commas like in spanish. another mistake i found of our writing is that we try to write like in spanish. That is also the reason of using lots of commas. our mistake is that we are doing, in fact, a translation with the texts we write. it is difficult finding faults because we are still learning so commit mistakes...
