特别提醒：鉴于BEC中级和高级考试，命题思路及考点一脉相承，很多考试技巧都可通用，请大家注意接下来所有指导文章，都同时适用于中级和高级的备考，而且我在课堂上一直强调，哪怕考高级的同学也非常有必要做一下中级的真题。） 　　很多同学反映，针对BEC听力的训练素材太少了，无非就是那几套真题，还有少的可怜的模拟题，做过一遍对完答案后就不知道接下来该干嘛了。其实，按照卷面要求完成答题远非听力训练的终点，而只是刚刚开始。根据我们在课堂上对于真题的分析，大家不难认识到，BEC听力之所以难，很大程度上因为它语速快而且句子结构、内容都很复杂。基于这种特点，我们需要在解题完成之后，回过头去，再次听录音材料并仔细揣摩考点和错误原因。这个过程就是所谓的“回听训练法”。 　　如何具体操作回听法？——拒绝“一翻二查三背出” 　　每次做完听力题后，先对一下答案，小结一下自己的做题表现，但此时不要急着看书后面的录音原文，而是合上书本，在没有任何可视材料辅助的情况下再听录音，此时尤其要注意听之前做错的部分，和感觉较难的单词和表达，并试着结合前后语句所形成的语境，猜测大概含义。只有在反复听还是无法理解的情况下，再打开书本看文字材料。 　　有的同学听力中一旦听到难词，二话不说翻看后面的原文去找出这个难词，再查文曲星，然后背出来。很多人就是受制于这种“一翻二查三背出”的训练模式，钝化了边听边主动思考的能力，听了半天

　一般说来，应对BEC中级听力特别是短文听力，其备考训练必须抓住竖听和横听两点结合来进行。所谓竖听，是指一套题目从头听到尾，从第一题听到最后一题。所谓横听，是指把相同题材和体裁的文章放在一块对照比较着听，从而迅速抓住同类型文章的规律，真正做到以不变应万变。文章一般用记叙的语言讲述人物的经历，较少有情节的描写或人物对话。通过这样反复对比听，可以使我们很快掌握人物传记题材文章的模式和考题思路，在短时间内抓住考点，做到举一反三。 　　笔者在此提供一套具体的短文听力训练办法，考生可以从BEC中级历年考题中选取10-20篇不同题材和不同体裁的文章，依据以下几个步骤，横竖结合来进行精听训练。 　　Step 1：第一遍听磁带时认真做题，对所选取的每段文章都认真仔细，注意时间，模拟考场氛围。做完以后还需注意统计对错个数，并分析选项设置特点，练习快速扫描选项的能力。 　　Step 2：脱离文字材料再听4-5遍磁带。此时绝对不允许照着文字材料听，应该反复使用录音机上的重复键，尽最大努力听懂全文内容。听第5遍或第6遍的时候，可以一边听一边将全文笔录下来，然后对照文字材料，看看笔录有什么问题，分析听不懂的原因，是语音、词汇还是语法？然后有的放矢地加以解决。 　　Step 3：在足够熟悉此段落中的内容后，打开文字材料，一边听录音一边看，并在段落中相应考点和问题答案，仔细体会，分析自己为什么被某些干扰项误导。

BEC说明 从字面上看，BEC还真不容易理解。到G搜一下，首先看到的竟然是FBI的定义[1]。引用FBI给的图，基本就能明白BEC诈骗的意思了。 这种网络诈骗，就是通过冒充（盗用）决策者的邮件，来下达与资金、利益相关的指令。根据FBI下属的IC3(美国网络犯罪申诉中心)统计的BEC诈骗数据（2013/10-2014/12），仅这一年多以来，美国就有1198个受害者遭受了BEC诈骗，直接损失179755367美元。 近期趋势 一般情况下，受害者是这样遭受BEC诈骗的：收到一封包含钓鱼链接的电子邮件，点击链接后，下载了恶意软件。恶意软件将受害者的密码和财务账号信息收集。 目前已经发现了三种不同类型的BEC诈骗（PSA I-012215-PSA），最近也确认了第四种类型的BEC诈骗。 类型1：伪造邮件、电话，要求转账到另一个账户 类型2：高管的email被盗用，像财务部门发送资金申请的邮件 类型3：员工email被盗用，向所有联系人发送付款要求 类型4：诈骗者冒充律师来处理机密或时间紧急的事件，或资金转移。这会给受害者带来心里压力。这通常发生在工作日快结束时，或接近财务机构快关门时。 保护措施 建立入侵检测系统，标记那些长得和自己公司邮件很相似的邮件（abc_company.com 和 abc-company.com） 记录那些和真实公司域名长得类似的山寨域名 涉及到资金交易时

So, under HTTP, we can make a POST request sending and receiving JSON without issue. When we try the same under HTTPS we got the error that the service is expecting text/xml insteas of application/json. Any suggestion on where to look?
