     In order to know a foreign language thoroughly(完全地), four things are necessary.   First,  we must

understand the language when we hear it spoken.   Secondly,  we must be able to speak it ourselves, 

 with confidence(自信) and without hesitation(犹豫).   Thirdly,  we must do much reading.   Finally,  we

must be able to write it.   We must be able to make sentences that are correct in grammar.  

     There are no shortcuts to success in language learning.   A good memory is a great help,  but it is not

enough only to memorize the rules from a grammar book.   It is not much learning by heart long lists(一

language.
