一、iBT听力理解试题答题要求如下： 1．显而易见，听力材料的形式是会话和讲话两大类，还是只让考生听一次。听完答题的依据是听懂并理解它的主题，或称中心思想，以及抓好与此相关的事实细节。另一些问题有更高的要求。它不仅需要考生理解听力材料的意思（sentence meaning），并且需要考生判断说话人、讲话人的意图（utterance meaning）。新iBT听力理解允许考生在听的时候记笔记，以备答题时用。 2．听力材料的某些部分前标有这个图标，它表明这部分材料只供考生听， 考生看不到。有些问题有特殊的答题要求，它们会显示在屏幕的灰色格子里。大多数问题的分值为1分；如果某个问题的分值超过1分，该题的答题要求会告知考生，它是几分。 3．考生每题必答。答完一题，需点击“Next”，再点击“OK”确认，才能做下一题。点击“OK”确认后，不能返回至前一题。 4．听力理解部分的答题时限为20分钟。屏幕上方显示时限倒计时。在放送听力材料时，倒计时不再显示。新网络TOEFL考试听力理解的问题，供考生边听边读。 一．iBT听力理解材料的特点。 新TOEFL的听力理解材料由两类组成：对话或讨论；讲话或演讲。对话是两个说话人就某个话题进行、长度约300词左右的听力材料；讨论为多人参与的围绕某个主题展开、长度约800余词的听力材料；而讲话或演讲指一个说话人的讲话，如老师的讲课，长度约700至800词。新TOEFL的听力材料非常强调说话的真实性（authenticity）。所谓真实性，其一，它的语速与本族语说话人（English native speaker）的语速相仿；其二，听力材料中很自然地含有fillers：sort of, uh, um, so, well, etc.；和口语体：we’re gonna talk about ...; An’ I’m gonna get into…；以及说话人下意识的、或是为了强调而有意识的“重复（repetition）”；等等。另一个显著的特点是讲话与讨论融合。如教授的讲课与学生的讨论结合；讲课后教授与学生的问与答。 二．iBT听力理解问题的特点。 新TOEFL的听力理解的题型呈多元化趋势。它保留了其招牌式的、用来得心应手的“四选一”多项选择题，还新增加了“多选多”选择题。此外，试题中的填表和配对题是新面孔。与以往不同，iBT听力试题鼓励考生在听时做笔记，笔记可供考生答题时使用。请看以下样题。 SAMPLE QUESTIONS:
