adolescents ...1.Why do you think some adolescents start smo...

各个国家因为风俗及法律不同，规定也不一样，拿美国为例，18岁是美国宪法规定的有选举权的年龄，所以在美国18岁是法定成人的年龄，服兵役和就业的最低年龄，但是在美国21岁才是真正成年的年龄，因为美国有很多限制卖羡 21岁以下的法令。比如，烟、酒在美国不准出售给21岁以下的青年，在公共场合不准喝酒，在赌场21岁以下的青年不准上赌桌和参与赌博，就连逛妓院和看脱衣舞都必须21岁以上！在美国很多成年人场所和俱乐部都必须21岁以上才能进入。所以在美国21岁是青年们最值得庆祝的生日，因为从此可以抽烟、喝酒和赌博再也没有人管了。

所以我中猛拍认为在美国children是3-15岁，adolescents，也就是teenage 11-19岁，18或21岁以上知姿是adults

When I was a child,I felt that my parents were over worried about me.They did not give me enough freedom as I wanted,and they liked to make decisions for me.As I grew up,I realized my parents love me more than any one else in the world because they are the ones who truly concern about my well being.
The most difficulty thing I encountered as I was growing up was the need of becoming independent from my parents.I was so used to the guidance of my parents when I was a child,but after I grew up,I have to start making my own decision which I believe is the greatest difficulty in the process of growing up.
"only adolescents will like adolescents".Yes,a teenager can only share his/her interests with other teenager.Due to a generation gap,adults can never understand the thoughts of a teenager.I think the reason that people say this is because of their personal experience.
有不懂的老散 请皮早问我燃含雀

青少年尊敬父母的哪些品质？respect后面加实体宾语，如果像一些概念性的，虚幻的宾语，要加in，如respect in the way of life, respect in China, respect in communism. 此句隐信中的parents指的父母是父母这个概念，而不是父母本身，所以加in
如果同样是父母，有特指嫌疑的就不用加in了，如：
“Jane I told you to respect your parents,how could you talk back to them again?"
珍妮我不是跟你说要尊敬你父母戚高吗，你怎么可以又跟他们拌嘴呢高携尺？

希望能帮上忙

Smoking is bad for our health,but some adolescents are smoking now.I think the first adolescent is the effects of his family member,they always smoking in front of the children.Before long,the children copy them to start smoking.Then,they smoking every where,so their friends and classmates start smoking.

One of the reasons why many adolescents are near-sighted is that they have been exposed to television too much.
