I can't understand any of the English, what should I do?

First of all you have to state which grade you are ah.

There is no other way to do English, you have to work hard, in case you fall behind and hurry to make up.

It is recommended that you must pass the vocabulary, at least the textbook word list vocabulary must be recognized will write and read, if you do not learn the phonetic symbols first phonetic symbols so that can help you read the words, a famous English grammar masters said that you must accumulate a certain vocabulary before you can learn the knowledge of grammar, you can even understand the meaning of what the sentence is how to go to do the problem? Not to mention reading comprehension to fill in the blanks. Play a good vocabulary foundation followed by contact with grammatical knowledge, more questions in class and listen carefully, the key content of the teacher will keep repeating. I'm talking about learning vocabulary is not mechanical memorization of words, and finally put in the sentence or paragraph. I used to be extremely poor in English, the test will know the mask, but through the efforts of the midterm English almost full marks. I hope to help you.
