I taught at private school often viewing my students as over-protected, worrying would happen when they went on to middle schools.Some did fine, and some did not. Some needed constant pats on the back, words of (encourage) and extra support, which I (happy) gave. Others were content on their own, needing little or no interaction（互动）with their teacher. for the most part, graduates would go on for higher schooling.I'd always supposed their parents were over-protective, for they were the ones that still walked their (five) graders into the classroom and met them at the school gate.Admittedly, I laughed at those parents, (think) their children would never learn to be (independence) if they didn't let go just a little. Then I had my own daughter. The moment I looked at her little face, I (know) I'd do everything in my power to protect her and make sure she always felt safe!
