Answer 1

Here is a announcement for everyone．A meeting is going to be hold in Room 101，Building 2at 7：00pm on March 3rd．It will mainly talk about problem including the dormitory safety，proper use of electricity，or the awareness of fire safety．The prevention of theft will also be mentioning．At least one member of each dormitory are required to attend∧．The participants should take a notebook with you，arrive in time and take notes careful．After the meeting you are to inform your roommates of what has been told and what measures will be taken for．
详
1．a改为an；考查冠词，announcement 是以元音音素开头的单词，前面用不定冠词an泛指"一个"．                          
2．hold改为held；考查动词，A meeting 和动词hold是动宾关系，故把hold改为held与前面的be构成被动语态．
3．problem改为problems；考查名词，problem是可数名词，根据句意"讨论宿舍安全，合理用电以及消防安全意识等方面的问题"可知应该用复数形式．
4．or改为and；考查连词，分析句子可知the dormitory safety，proper use of electricity，the awareness of fire safety是并列成分，故用and连接最后两个并列成分．
5．mentioning改为mentioned；考查动词，此处用过去分词形式mentioned与系动词be构成被动语态．
6．are改为is；考查主谓一致，主语 one member （一个成员）是单数，故动词用单数形式is．
7．attend后面加it；考查代词，attend是及物动词，此处指"参加会议"，故用it指代the meeting．
8．you改为yourselves；考查反身带吃的用法，with oneself意为"某人自己"，句意为"与会者自己要带一个笔记本…"．
9．careful改为carefully；考查副词，此处用副词作状语，修饰动词短语take notes．
10．去掉for；考查动词，take measures意为"采取措施"take后面不加介词，故把for去掉．
