  var inter = [['小A','女',21,'大一'],['小B','男',23,'大三'],['小C','男',24,'大四'],['小D','女',21,'大一'],['小E','女',22,'大四'],['小F','男',21,'大一'],['小G','女',22,'大二'],['小H','女',20,'大三'],['小I','女',20,'大一'],['小J','男',20,'大三']];
  for(var i=0;i<inter.length;i++){
      if(inter[i][1]=='男'||inter[i][3]!=='大一'){
          continue;
      }
      document.write(inter[i][0]+'<br/>');
  }
