讲座/报告作为六级听力中的压轴部分，值得考生格外重视：1) 分值高：10个选择题，占全卷20%的分值，占听力部分一多半的分值；2) 篇幅长：文章约350—450词，远远长于短文听力（240-270词）；3) 内容深：内容专业性强，题材广泛，甚至涉及到我们完全陌生的研究领域。下面以一篇样题“电子商务产品与服务的性质”为例：
I’d like to look at a vital aspect of e-commerce, and that is the nature of the product or service. There are certain products and services that are very suitable for selling online, and others that simply don’t work.Suitable products generally have a high value-to-weight ratio.【Q23】 Items such as CDs and DVDs are obvious examples. Books, although heavier and so more expensive to post, still have a high enough value-to-weight ratio, as the success of Amazon, which started off selling only books, shows. Laptop computers are another good product for selling online.Products which are potentially embarrassing to buy also do well in the virtual environment. Some of the most profitable e-commerce companies are those selling sex-related products or services. For a similar reason, online gambling is highly popular.Products which are usually considered unsuitable for selling online include those that have a taste or smell component.【Q24】Food, especially fresh food, falls into this category, along with perfume. Clothes and other items that need to be tried on such as diamond rings and gold necklaces are generally not suited to virtual retailing, and, of course, items with a low value-to-weight ratio.There are exceptions, though. Online grocery shopping has really taken off, with most major supermarkets offering the service. The inconvenience of not being able to see the food you are buying is outweighed by the time saved and convenience of having the goods delivered. Typical users of online supermarkets include the elderly, people who work long hours【Q25】and those without their own transport.23 What is important to the success of an online store?A) The guaranteed quality of its goods.B) The huge volume of its annual sales.C) The service it provides to its customers.D) The high value-to-weight ratio of its goods.24. What products are unsuitable for selling online?A) Those having a taste or smell component.B) Products potentially embarrassing to buy.C) Those that require very careful handling.D) Services involving a personal element.25. Who are more likely to buy groceries online?A) Those who live in the virtual world.
B) Those who have to work long hours.C) Those who are used to online transactions.D) Those who don’t mind paying a little more.浏览答案和原文可以发现，所有问题的答案都能在原文中找到对应的语句（划线部分），几乎不需要什么逻辑推理。所以，表面“高大上”的讲座/报告，其实只需要你边听边“等”答案，即“听到什么选什么”，选项中没有提到的多半信息，不用细心理会。另外，讲座/报告都有大体固定的套路，出题套路也比较稳定，与托福听力相仿。比如上面这篇讲座：第一段是主题段，接着几段讲适合网售的产品和服务，倒数第二段是不适合网售的产品，最后一段补充例外情况，“exceptions, though”是关键的转折词。正文三层意思，正好对应三个问题。
如何应对这种题型？先从四六级官网上找到完整的样题——有条件的就打印下来——仔细研读几遍。然后有针对性地找相关听力素材练习。网上有很多小型英文讲座，比如广受世界网友喜爱的TED演讲，就是练听力长知识的绝佳素材。TED演讲的特点是毫无繁杂冗长的专业讲座，观点响亮，开门见山，种类繁多，看法新颖。以下面一段TED讲座（四分钟）为例，大家可以边听边做。题目：
这是Johan Rockstrom的演讲，主题是“Let the environment guide our development”。开头第一句就让人警醒和深思：“We live on a human-dominated planet, putting unprecedented pressure on the system on earth.” 地球面临危机，挑战与机会并存。简要介绍地球发展史之后，视频部分的重点是讲人类出现后地球遭受的四重压榨（quadruple squeeze）。听的过程中，注意几个反复出现关键词“planet/ phase/crisis/pressure/squeeze”，以及表逻辑思路的but/because/so/first/second/third等词，就容易抓住讲座要点。
