Answer 1

分析 文章讲述了校园暴力．选择校园暴力引起了广泛关注，我们要想方设法避免它的发生．遇到校园暴力时，要及时和父母老师沟通，不能以暴制暴．

解答 答案：61．exist；考查动词．句中did是对谓语动词的强调，后面要用动词原型．   
62．Obviously；考查副词．句中obvious修饰整个句子内容，要用副词形式．  
63．a；考查冠词．句意表达的是泛指，要用不定冠词来限定．    
64．which/that；考查连词．句中calls for our great concern修饰phenomenon，是一个定语从句；从句缺少主语，且先行词phenomenon指物，要用which或that来引导． 
65 happening；考查动名词．句中happen作介词from的宾语，要用动名词形式．
66．if；考查连词．句意表达的是假设，要用if来连接条件状语从句．  
67．be learned/learnt；考查语态．句中learn与主语violence构成动宾关系，要用被动语态；learn的过去分词既可以是规则变化，也可以是不规则变化． 
68．what；考查连词．句中they see on television or on the Internet作介词from的宾语，是一个宾语从句；从句缺少宾语，且句意表达的是事情，要用what来连接．   
69．with；考查介词．句意表达的是用某种工具，要用with来表示；answer violence with violence以暴制暴． 
70．should/ought to/must；考查情态动词．句意表达的是建议，每个学生应该注意言行，远离暴力．

点评 语法填空题是考查学生的语言运用能力．解题时，要在理解文章的基础上，灵活运用语法知识，如词性，时态，名词单复数，连接词，代词，冠词等判断空白处应填写的内容．答完后，还要通读全文，核对所填单词形式是否正确，是否符合语境．
