还会帮你回忆起你在题目中听过的人名和事物等名称 3 注意各选项中的主要区别 你可能会看到一些不同的名字或地点或不同的动词 这些不同之处将会帮你确定这道题中哪些是你要听的关键 即关键词 4 克服犹豫不决的毛病 对自己有把握的试题应快速作答 对无把握的试题也要在所听信息的基础上排除错误选项 进行优化处理 不会作答的 立即暂时搁置 准备听新的题目 5 目前高考听力测试中短文理解大部分是记叙文或讲话稿 所以听录音时重在听懂每句话的意思和内涵 注意捕捉文中所涉及的人物 who 事件 what 时间 when 地点 where 原因 why 方式 how 程度 howlong howsoon howmuch 数字 howmany howmuch 选择 which 等 以便检查答案 6 注意听短文的首句和首段 文章的开首和开首段 往往是对短文内容的概括 如讲话目的 主要内容 作者 论点 故事发生的时间 地点及事由等 7 不管听什么材料 注意力一定要集中在整体内容的理解上 千万不能只停留在个别单词或单句上 听不清时马上放弃 不要强迫听清每一个词 要把重点放在听关键词即实词上 一边听一边把要点及回答问题的关键词记下来 8 保持良好的心态 千万不要因为某些地方听不懂而心烦意乱 纠缠不休 一定要平静地听下去 否则会导致既丢 芝麻 又丢 西瓜
