Part A

从题型难度上来分析，选词填空一向存在难度大，得分低的状况，因此在课上我们建议把该题型放在最后去解决。

选词填空解题的核心在于：划分词性。这一步做得好的话，事半功倍；做不好的话，事倍功半。划分词性后，应该采用“先易后难，逐个击破”的策略，具体而言副词和形容词一般比较少，因此先从这两类单词突破。

Part C

四级考试刚刚落幕，几家欢乐几家愁。

写作部分严重坑爹了，而阅读部分，正如我在课上预料的，难度基本保持稳定切略有。

关于文章内容，上过广州新东方阅读课的同学一定不会陌生：我在课堂上讲过，四级阅读常考内容：经济学，医学，以及今年特别关注的网络安全话题，这次都考到了。

文章几乎没有难词和生僻词，句子结构简单，提问方式也是中规中矩，细节主旨较容易把握，考生只要抓住文章主旨便可以很好的理解文章意思。

从解题方法和技巧方面来看：区域原则（一段一题）+顺序原则（出题顺序与行文顺序一致）+段落首末句原则依然非常实用。2篇文章10道题，有8题答案处于段落首末句位置。这是我在课堂上一再强调的内容，认真学习并勤加练习的同学，相信会在本次考试的阅读部分取得不错的分数。
