(一)语法在听力中的作用：
    在听力理解中，如何培养自己在片刻间获取信息，并能加以归纳和理解，除了要掌握英语口语中基本的语音现象外，还应熟练掌握英语语法中以及口语中的一些习惯表达法，而我们所谈到的听力中的语法又包括：
    1、听力中的词法
    在听力理解中，代词的指代、数词的读法、动词的时态、语态等其它词性的用法常常成为数词的用法理解的关键，并以数词频率最高。
    for example
    1)m: could you tell me the tometuble of the school bus?
    w: well, the bus leaves here for the campus every two hours from
    7: 00 a.m. but on saturdays it states half an hour later.
    a. at 7:30 b. at 9:00 c. at 8:00 d. at 9:30
    2)m: i'd like to make two reservation on hight 651 for june 8 th.
    w: i'm sorry, we're booked up on the 8th, but we still have a few
    seats av ailable on the 9th.
    q: when does the man want to leave?
    a. on the 9th of june. b. on the 8th of june.
    c. on the june. d. on the 7th of june.
    explanation and expansion:
    a) 参考答案：1）d 2）b
    b) 辨析：
    1) 从以上题中不难看出，考生必须听清题干所问，如1)中的the second bus on saturdays ，并对已知数据进行分析，平常为7:00，每两小时一趟，星期六晚发半小时，那么星期六第二趟车为7:30+2=9:30，d正确。
    在2)中，我们必须了解在语法中一些数词的排列顺序，第651次航班: hight 651，第七路公共汽车: bus number seven，而时间顺序，美式为：日，月，年，英式为：月，日，年
    动词的语态，时态及语气
    for example:
    1)m:the city council has finally voted the founds to build a new
    high school?
    w:it's about time they did it, i don't know what took them
    solony.
    q:what's the woman's opinion about the school?
    answer: it should be built.
    2)w:what an accident! if you had been careful, things would
    not be as they are.
    m:what do you mean, it was my fault? if it were, surely i would
    take all responsibility for it.
    q:what does the man mean?
    answer: he is not to blame.
