A waitress (woman assistant) put a glass of water in front of him. “How much is an ice cream sundae?” “Fifty cents”, replied the waitress.

    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, correctly with confidence(自信) and without hesitation(犹豫). Thirdly, we must be able to write it. Finally, we must be able to make sentences that are correct in grammar.
    There is no short way to succeed in language learning. A good memory(记忆) is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use 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 practice speaking and writing the language whenever(无论何时) we can.
    小题1:The most important things to learn a foreign language are________.
    A．understanding and speaking
    B．hearing, speaking, reading and writing
    C．writing and understanding
    D．memorizing and listening
    小题2:Someone hears and writes English very well, but he speaks it very badly. This is because ______.
    A．he doesn't understand the language when he hears it spoken
    B．he doesn't have a good memory
    C．he always remember lists of words and their meanings
    D．he often hesitates to practise speaking it
    小题3:One can never learn a foreign language well only by________.
    A．much practice B．studying the dictionary
    C．learning through useD．using the language
    小题4:Which of the following is the most important in learning a foreign language?
    A．A good memory.B．Speaking.C．Practice.D．Writing.
    小题5:"Learn through use" means________.
    A．we use a language in order to learn it
