     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

览表) of words and their  meanings, studying the dictionary and so on. We must learn by using the

language.

     If we are pleased with a few rules we have memorized, we are not really learning the language. We

must "learn through use." Practice is important. We must practise speaking and writing the language

whenever we can.
