text: -- 找出所有影片描述为非 boring (不无聊) 的并且 id 为奇数 的影片，结果请按等级 rating 排列。
  
  -- 例如，下表 cinema:
  
  -- +---------+-----------+--------------+-----------+
  -- |   id    | movie     |  description |  rating   |
  -- +---------+-----------+--------------+-----------+
  -- |   1     | War       |   great 3D   |   8.9     |
  -- |   2     | Science   |   fiction    |   8.5     |
  -- |   3     | irish     |   boring     |   6.2     |
  -- |   4     | Ice song  |   Fantacy    |   8.6     |
  -- |   5     | House card|   Interesting|   9.1     |
  -- +---------+-----------+--------------+-----------+
  
  -- 对于上面的例子，则正确的输出是为：
  -- +---------+-----------+--------------+-----------+
  -- |   id    | movie     |  description |  rating   |
  -- +---------+-----------+--------------+-----------+
  -- |   5     | House card|   Interesting|   9.1     |
  -- |   1     | War       |   great 3D   |   8.9     |
  -- +---------+-----------+--------------+-----------+
