To improve your English reading, you should, first of all, choose something you feel important or interesting to read. Dont try to read everything. You should begin with those written in simple English. Dont read those which prove difficult for you at the very beginning.
While reading, dont read too slowly or look up every new word you meet with. After reading a passage and having its main idea in mind, you may turn back and read it again. This time you read it slowly and look up some new words if necessary.
Keep on reading in this way and youll surely make progress little by little.
