Hi, first of all you need to determine what level of English you are at, then take steps to improve. This Italki grammar site may help you http://www.italki.com/knowledge/page/ENGLISH%20GRAMMAR.htm

For non-English speakers I know that grammar can be a headache...But like what I always say to my students, there's no need to rush in learning..JUST TAKE IT SLOW and always start with the basics. For grammar, you first have to be familiar with the 8 Parts of Speech (noun, pronoun, verb, adverb, adjective, conjunction, preposition and interjection) and believe me, you will go a long way and you will find it much easier to learn the technicalities of English grammar :)

英语语法， 也不过就是主谓宾， 定状补。 没有格位变化。 词性搞清楚以后， 按照既定的顺序拼起一个句子就不会太难了。 基本就是熟能生巧。 还有就是相对于语法来说， 词汇量更为重要。

ok thanks a lot i will try to do it

English without grammar will make you more mad, believe me. Start with the basics, and build out from that. You'll find that grammar gives you piles of hints about what is happening, when, and who is doing what to whom. If you find a sentence where the grammar confuses you, cut out the grammar (ie. write it in basic words) and look at it again. You'll see what the grammar would tell you, if it were there. ;)
