台湾籍旅美老师今天交给我们的句子是：

12, 13-years-old entering puberty often aloof, particularly towards adults. Also may be self-absorbed, but often vulnerable, looking for a peer group, looking for a way to fit in. These young adolescents need worthy role models.
12，3岁的青少年进入青春期后经常表现得很冷淡，特别是对成年人。他们也会比较专注自己的事情，从而比较脆弱且容易受伤。所以通常他们寻找同龄人团体，或想办法与大家相处。这些青少年需要一个值得尊敬的模范。
