【解析】
这是一篇记叙文。文章主要讲述我们如何为参加学校海报展览活动作准备。
1.考查动词时态。分析句子可知，动词participate在句中作谓语，由句中“Last month”表示上个月，表达的是过去时间，所以谓语动词participate需用一般过去时participated。故将participate改为participated。
2.考查形容词。分析句子可知，名词experience前需用形容词修饰，memorably是副词，需转变为形容词memorable。故将memorably改为memorable。
3.考查被动语态。分析句子结构可知，Having informed在句中作状语，和主语we之间是被动关系，需使用被动结构Having been informed。故在Having后加上been。
4.考查名词。分析句子可知，形容词full后需接名词，prepare是动词，需转变为名词preparation。故将prepare改为preparation。
5.考查介词。分析句子可知，谓语动词supply表达supply sb. with sth.“向某人提供某物”时，需用介词with。故将for改为with。
6.考查定语从句关系词。分析句子可知，“whom proved to be a valuable resource and gave us lots of practical advice.”在句中作非限制性定语从句，修饰名词teacher，先行词teacher在定语从句中作主语，指代人，需用关系代词who。故将whom改为who。
7.考查非谓语动词。分析句子结构可知，动词collect在with复合结构中作宾补，和名词material之间是被动关系，需用过去分词collected。故将was去掉。
8.考查人称代词。句意：我们每个人都被布置了不同的任务，这些任务我们都倾注了我们全部的努力。根据句意可知，their表示的是他们的，和句中的us，we指代不一致，需用our指代“我们的”。故将their改为our。
9.考查冠词。分析句子可知，名词exhibition表示特指“学校海报展会”，需用定冠词the。故将an改为the。
10.考查代词。分析句子可知，名词attention表示“注意力”的意思时，是不可数名词，需用much修饰不可数名词。故将many改为much。
