[误] He is a too experienced teacher to care what kind of question the students may ask.

[正] He is too experienced a teacher to care what kind of question the students may ask.

注：如果按正常的词序，则 He is a too experienced teacher.(他是一位很有经验的教师。)不能算错，但是由于此句以 too...to 结构贯穿整个句子，这就必须将 too 和 experienced 提至冠词之前。
