题目分析：本文是一篇发言稿。在文中主要向同学们介绍了当听到火警时要如何去做的问题。首先学生们要站在门口等老师领到外面。还要保持冷静沉着，不要惊恐失措，不要乱跑，而且要和老师、同学们在一起。如果是假警报，没有发生火灾的话，老师会把同学们领回教室，如果发现有人失踪要立即通知老师等。
小题1:with ---about 。考查短语搭配和语境理解。I am going to talk with what you should do根据句意可知talk后是谈论的内容，talk with 意思是“与某人交谈”；talk about意思是“谈论某人或某事”，故把with改为about。
小题2:go---goes 。考查主谓一致。when a fire alarm go off。从句中的主语是a fire alarm，根据主谓一致的原则可知谓语动词应该用单数，把go改为goes。
小题3:wait 后加 for 。考查短语搭配。and wait your teacher to lead you outside。固定短语：wait for“等待”，其中wait是不及物动词，如后面有宾语，则加介词for。
小题4:classmate ---classmates 。考查名词单复数。Stay close to your teacher and classmate.从内容可知此处是指许多同学们，应该用复数形式，把classmate改为classmates。
小题5:trying ---try 。考查谓语和非谓语。Don't panic or get out of line, and trying to remain quiet。解题关键是and连接的词前后需一致。根据前面panic判断此处用动词原形try。
小题6:calmly---calm。考查形容词的用法。remain quiet and calmly。Remain是系动词，后面用形容词作表语，故把calmly改为calm。
小题7:a –the 。考查冠词用法。Soon the firefighters will come and put out a fire.。在文中fire是特指概念，故用定冠词the。
小题8:us---you。考查人称代词的用法。your teacher will lead us back to the classroom.根据前面your teacher判断此处指带领“你们”，把us改为you。
小题9:去掉when。考查宾语从句。If you notice that when someone is missing and hurt, Notice后的宾语从句意思完整应该用that引导，when多余，所以去掉when。
小题10:and—or。考查连词的用法。If you notice that when someone is missing and hurt。从句意判断此处是提出两种假设情况，所以用or表示“或者”，把and改为or。
