2. It belongs to expression description, which highlights the nervousness, timidity, fear and shame of boys.
3. I am proud of Teacher Qin when I think of 10 (2 points).
Teacher Qin is a caring (kind) teacher with a sense of responsibility (stressing principles) and full of educational wisdom (paying attention to educational methods).
5.①: Disapprove. The little boy's mother's education is simple and rude, which is easy to hurt the child's tender heart. Like teacher Qin, she wants to influence children with gentle breeze and drizzle and love. Example 2: Agree. As the saying goes, "strict teachers make excellent students." For particularly naughty children, "bamboo whip" is an effective means.
