Learning Tips
听力的解题技巧
解题时间紧、任务重、难度大,这就要求学生不仅有扎实的听力基础,较强的听力能力,丰富的语言知识,还要具有敏捷的反应速度和正确的解题方法、解题对策、应试技巧,以巧取胜。总的说来,要注意以下技巧的培养。
1.关注所给题干,作好听前预测
利用听录音前的时间,迅速地捕捉每个小题题干选项所提供的信息,预测短文或对话可能涉及到的内容,这样听录音材料时就有的放矢,有所侧重,提高答题的准确率。但也看实际情况,针对不同题型,不同长度的选择题来把握听前的预测方向。听时注意wh-项目（who,what,when,where,why,how,how long,how soon,how much,how many,which）等方面的信息。
2.抓关键词和主题句
例:NMET 2000,12
Who are the two speakers?
A.A man and his wife.
B.A man and his sister.
C.A man and his girlfriend.
如果我们在听时能抓住听懂所在材料中的这样一句话:
It’s quite unlike when we were first married.若能抓住married 这样的关键词,便能选出A项。
但听的过程中也要顾及全局,不要过于偏重于某一词或某一句,造成一叶障目,不见泰山。
3.脑记与笔记相结合。
这对于做第二节(较长对话和独白)的题尤为重要。
笔记的技巧可分为以下三种:
1）提纲挈领,记主题句。听录音时记下含信息量多的句子或关键词或词组,按照原文信息逐一记录。其特点是条理分明、全面,有利于对全文的记忆和理解。
2）利用缩写词和符号。
做笔记时充分利用缩写词和符号,可以大大提高笔记的速度。缩写词表示的范围很广,如人名、地名、月份、星期等。代用符号也很多。如:？—question; =—is like,the same;≠—Not equal,is not like,different ; e.g.—for example; >—greater than ; < —less than ; ∵—because; ∴—so ;学生应在日常学习中掌握缩写词。
3）自造缩写词。对一些词采取自己认可的简略形式,也是行之有效的速记方式。
4.没听懂时的对策。
听力考试不同于其他的考试类型,考试信息一读而逝,“从不为谁停留”。尤其是第一节,虽然是简短对话,但仅读一遍。所以一定要有充分的心理准备,某些地方听不懂是很正常的,而且没有什么思考的余地,所以要学会放弃,不可紧张。否则会影响做下面试题的情绪。
