托福综合口语听力部分2个易扣分问题细节讲解
托福综合口语听力误区：对话双方都仔细听
我们都知道在最终的口语表达中只需陈述其中一个人的态度及理由，所以两个说话者的信息都听无疑只会分散精力，并且另一个人所描述的信息也可能会被考生误引入到最后的口语表达中,违背题目要求给出错误信息。
应对方法：找出主角(leading speaker)
只听一人在听力对话一开始的时候不要着急记笔记，这样很容易无法分清主次。先把两个人的分别一句话听完，基本就可以分清主角和次角，因为，主角往往会持有很强烈的支持或反对态度，确定下主次以后，就可以专注只听一个人并记笔记了。
托福综合口语听力误区：听力对话要边听边写
有的考生曾经抱怨说自己的笔记都快赶上听力原文了，可是分数却不尽如人意。其实这又是“完美主义”心态在作怪了。考生总是不放心，对话中的每一个细节列举都不放过，结果在口语表达时内容冗长，却依然会遗漏重点信息，而这正是Task 3丢分的主要原因之一。托福口语考察的是抓住重点的能力，并不是考生的书写速度。
应对方法：笔记只需要记主角所给出的态度(赞成/反对)+reasons(key words)
在听力对话中寻找关键信息，快速识别信号词或信号句就显得更为重要，这是听力的必备技巧之一。例如在Official Guide的某个听力对话文本中，我们可以看到“But I can see why”，“ And the other thing is ”，“I’m doing OK, but the facilities here are so limited.” 这些明显的信号句所引出的关键信息，所以笔记可记为：many students(班级+) ，hard get personal attention(关注￬)，not job(工作难)，facilities￬equipment ￬(设备￬) out of date(过时)
