My writing English is not so good as I wish it. I was thinking is there anybody who can help me out with some recommendation of book or something else?
Hi Kambiz, for good writing you should have good grammar knowledge as well. But the grammatical knowledge is not enough since you need to read more and as you read you get familiar with English texts and genres and how to write. The file that I send you is a good book to improve your writing.
The first chapters may seem boring for you but later that you continue to section 3, 4, 5 you will find your path.
کتابی که برات اینجا گذاشتم منبع خوبیه اول کمی علامت ها و نقطه گذاری و گرامر رو در قالب سوال برات مرور می کنه جلو که رفتی تو فصل 4 و 5 نوشتن یک مقاله رو کامل یاد میگیری. سبک کتاب به روشی هست که از علائم خیلی جزئی شروع میکنه تا به جمله و بعد پاراگراف و در نهایت کل متن میرسه.
Sorry later that I visited your profile I felt that you may need proofreading skill so I added another source which is good for acquiring proofreading, revising, and editing skill.
I would recommend starting with REF-N-WRITE scientific paper writing tool. This tool allows you to import text from previous papers relevant to the subject area in MS word. While you are writing your paper, you can just search for similar statements from other authors and inherit their vocabulary and language to improve your paper. It also comes with a library of academic phrases that you can readily use to polish your paper. Here is the link for the site.
