托福听力几个部分？
共4个section，每个section约20个问题（除最后一道题），每道题有15秒的读题时间。 前三个section是校园场景讨论，最后一个section是社会话题讨论。 其中前两个section涉及的话题比较日常，后两个section会接触一些学术话题。
考试形式为录音播放，考生答题。 每个section的录音长度约为30分钟；在正式播放试题录音之前，会先给你几分钟的时间浏览题目和选项以及记笔记(备注：记笔记的这段时间是不计入总答题时间的)。 回答每一问都需要作答（注意：回答问题的时候不需要复述问题，只要将听到的问题和答案作答即可）。
例如：回答下列问题：Question：What are the advantages of living off campus？ Answer：There are several benefits to living off-campus. First of all，it‘s a lot closer to class．You can walk or bike to many buildings on campus and there are usually shuttles that drive around．Secondly，there is more space in an apartment than there is in a dorm．You have your own kitchen and maybe even a backyard．The only thing you might miss is the easy access to the dining hall，but if you live in the area where the dining commons is located it doesn't matter too much．
