①before改为ago 副词错误。ago表示“从事情发生到现在时间过去了多久”，需和过去时连用。before指“从事情发生到过去某个时间是多久”，常和完成时连用。由下文对活动的介绍可知，活动是几天前举办的，故此处用ago。
②删除appreciate后的what 引导词多用。what可引导宾语从句，但此处宾语是名词短语，故what多余。
③dated改为date 动词时态错误。此处date back应用一般现在时表示一种客观情况，且前面主语为复数形式，故用date。
④as well后加as 固定搭配错误。as well as意为“也，除……之外，以及某事物/某人”。
⑤Prepared改为Preparing 非谓语动词错误。此处作状语，且prepare与主语we是逻辑上的主谓关系，故用现在分词形式。
⑥hour改为hours 名词单复数错误。one and a half后跟名词复数。
⑦under改为with 介词错误。with the help of...“在……的帮助下”。
⑧certain改为certainly 词性错误。修饰动词looked应用副词。
⑨them改为her 代词错误。我们都很钦佩她娴熟的化妆技巧。此处指上文中的Miss Mei，故用her。
⑩an改为a 冠词错误。meaningful读音以辅音音素开头，故应用不定冠词a。
