      "题号: 002859 , 字段: remark 中已添加数据: 学生很少会从定义域出发去考虑奇偶性问题，考虑定义域的学生中还有一部分是说``因为定义域关于原点对称，所以$b=1$''.\n",
      "题号: 011131 , 字段: remark 中已添加数据: 最值能够取到学生还是有一些不写（周双表示都扣了4分）.\n",
      "题号: 002968 , 字段: remark 中已添加数据: 第(2)小题学生极少能关注到定义域.\n",
      "题号: 003884 , 字段: remark 中已添加数据: 有点抽象, 反例难举.\n",
      "题号: 001221 , 字段: remark 中已添加数据: 第(3)小题有学生未考虑定义域，有学生在化简过程中出现了分母为$x$.\n",
      "题号: 009517 , 字段: remark 中已添加数据: 学生举不来反例, 有的只考虑了$f(0)$,$f(1)$,$f(2)$的值. 还有一些长篇大论不举反例的.\n",
      "题号: 001331 , 字段: remark 中已添加数据: 太难了，不适合作为第一轮讲义的题目. 太难了，不适合作为第一轮讲义的题目. 太难了，不适合作为第一轮讲义的题目.\n",
      "题号: 009522 , 字段: remark 中已添加数据: 第(2)小题学生很多不会分三种情况讨论. 第(1)小题有些学生把自变量取在$(-3,0]$.\n",
      "题号: 002884 , 字段: remark 中已添加数据: 少数学生不能分辨``定义域上单调''和``分若干个区间单调''.\n",
      "题号: 004265 , 字段: remark 中已添加数据: 第(2)小题有点难, 用分离变量和二次函数讨论做对的都有, 但是对面上太难了.\n",
      "题号: 010197 , 字段: remark 中已添加数据: 可能需要加一个``用函数观点求解''\n",
      "题号: 003013 , 字段: remark 中已添加数据: 许多学生的答案是开区间, 可能是用了零点存在定理.\n",
      "题号: 000555 , 字段: remark 中已添加数据: 题目非常难, 通过同样题目的测验确定讲解是否有效.\n",
      "题号: 001227 , 字段: remark 中已添加数据: 学生有些未想到求导, 瞎猜的答案.\n"
