请评析以下教师的做法。
在一次公开课上，学的是Junior English For China Book Ⅱ Lesson 51。老师要让学生根据书上的图画，猜测Ann的朋友在送礼物时会对Ann说什么话，同学们七嘴八舌地说开了：
Student A：Ann!Here is my birthday present．I hope you like it．
Student B：Ann!Here is my birthday present．I hope you will be happy and healthy．
Student C：Ann!Here is my birthday present．Happy birthday to you!
Student D：…
这时男生E突然举手，站起来说：
Student E：I think Ann’s friend LiLei will say，“Ann!You are beautiful．I love you!Here’s my present．I hope you like it．”
当时所有听课的老师和同学都笑了。上课的老师先是一惊，然后马上微笑着给了男生E一块橡皮，并且说：
Teacher：I think you are a clever boy．You speak good English．Here’s my present for your answer．
I hope you will like it．
Student E：Thank you!I like it．
