what to do for improving the reading?

For you to be able to enhance your comprehension, you need to be able to know the meaning of each word that you are trying to read. Reading without comprehension is useless, and will only lead you to failure and waste of time of reading. As for the moment, I advised you to get with you a dictionary, as this will really help improve your vocabulary and understanding, thus leading you to broad understanding while reading. Personally, I am not that quite good in English, as this is only my second language. However, despite of that, I still manage and encourage myself to learn more by reading some relevant books, as this will help enhance my English comprehension. Have a nice day and God speed!
