小题1:

Don’t choose a rather difficult book or a too easy one for yourself to read. A book full of new words will make you feel discouraged quickly. To understand those new words, you have to turn to the dictionary quite often. It seems that you are not reading the book but the dictionary. It has no fun at all! On the contrary, a too easy will only waste your time and cannot do any help. The two extremes may at last make you give up reading. So it’s better for you to find a proper book with no more than five new words on each page.

 

 
小题2:

  If you come across a new word, do not look it up in a dictionary as quickly as possible. Leave it alone and guess the meaning of it based on the content of the text. This ability is quite necessary in reading. If you know your guess is right later, you will be highly excited at your “success”, and your interest in reading is well stimulated. If a word really prevents you from understanding the whole passage, turn to the dictionary by then. I am sure you can remember this word very well, as it has left you such a deep impression for its “troublesome image”.

 

 
小题3:   

  To comprehend what you are reading, you should think while you are reading, then form your own ideas on some special issues. Try to scribble some lines—a very short journal, to express your ideas. Your writing does not need to be quite formal but very expressive. This practice can make you communicate with the original English authors. Day by day, your way of thinking in English will turn into a native way, which is quite important for English writing.

 

 
小题4:

   Language has its own beauty, no matter Chinese or English. Don’t merely take English as a “test”. Take it as an “entertainment” instead and you will enjoy it through learning. Maybe you should find some beautiful literary works such as a prose or a poem to read, if you like. Try to read them as loudly and passionately as you can. During this process, not only can you enjoy yourself by the great emotions of the writers, but also your pronunciation and your manner of speaking English will be improved.

 

 
小题5:

  The last but not the least, keep on reading. If you cannot keep it as a habit, you will suffer from paying without gaining.
