Ｉ received this great question from one of my internet friends:

  
"不知道阁下看过《美国派》系列的电影没有，其中的关于性的自由和开放是我们国内大学生，可以说是很难想象的。我很怀疑其荒诞和夸张性，不知道真是情况如何。 美国的青少年自由好像过多的给人以随意和不负责任，但我所了解的，只是从电影上，，做戏而已，其中偏颇，还望斧正."

That is a very good question.  Yeah, while the story in "American Pie" is a little bit exaggerated夸张, the desire渴望 for sex in American teens青少年 is very real真实的.  In the US, some schools start teaching sex education性教育 as early as the 5th grade (小学5年级）and go through to high school. 

    One of my best trips旅游 was to Hawaii 夏威夷 in the summer夏天 of 2005.  The island岛 we visited was Maui毛伊 which is less touristy游客 than other islands and had an amazing惊奇 collection地方 of natural自然 wonders.  We spent 10 days in Maui, and the most exciting thing for me was diving潜海 with 150 years old sea turtles大海龟.  They were so calm平静 and peaceful平和 when I dove with them.  I felt like I was one of them and the stresses压力 of  human life生活 just faded away渐渐地淡去.  I wish I could have swam with them to the deep ocean...  
(I will post some photos照片 and videos录相 about my Hawaii trip later.)   We stayed
