2、注意重复的词语，这些词通常会给你一些线索，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（how long，how soon，how much）、数字（how many/how much）、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”的被动局面。 www.themegallery.comTranslationIt would make a big difference to our environment if we planted more trees around the school.

2、注意重复的词语，这些词通常会给你一些线索，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（how long，how soon，how much）、数字（how many/how much）、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”的被动局面。 www.themegallery.comTranslationIt would make a big difference to our environment if we planted more trees around the school.
