  Part B 部分和以前的高考听取信息有共同的地方,就是都

  会考查考生获取听力材料主旨大意、以及捕捉关键信息的能力。

  关键信息通常是以数字、时间、地点、行为、感受等形式出现

  在听力材料中,如我们常常会听到材料里面出现房号 Room

  521,电话号码 8740315,或者是地址 The Oriental Hotel

  等等。

  因此同学们要对这类信息特别留意,并及时做好记录。 例1:

  With photographers never far away, the young president strolls

  through construction camps, dines _______________ with the men

  and shares milk with John Stevens. Question: Where did the president have meal during his visit? Key: In a mess hall.(此处要捕捉的信息是总统就餐的地方) 例2: Vanessa: Oh absolutely! I mean, ___________________, and I remember I was in the middle of making an album. Question: What is the last time when Vanessa performed in Hong Kong? Key: In 1997.(此处要捕捉的信息是时间)

  在记录时,要巧用符号,快速记录。在平时的训练中,我们

  可以用某些特定的符号来快速记录。如在记录国家名字时,我们

  可以用前两三个字母来表示:China—Ch; Japan—Jap;其他较长的

  单词如:organization—org; activity—act; phenomenon—phe 等等。
