7．"There's no point in talking with you：you don't understand me．You don't even know me．"A teen spits these words at a parent，who is hurt and annoyed．How can her own child say these things？She's worked hard getting to know him，learning to read his feelings from his voice and gestures．How can her own child now say to her，"You don't know who I really am"？
Nothing shakes a parent's confidence as much as the starting of a child's adolescence．The communication that has flowed easily through words，glance and touch becomes a minefield（雷区）
Recent discoveries that the human brain undergoes specific and dramatic development during adolescence offer new"explanations"of teen behavior，particularly of the impulsiveness（冲动） of teenagers．During this development，there may be too many synapses（神经元突触） for the brain to work efficiently，the mental capacities of decision-making，judgment and control are not mature until the age of twenty-four．
An old explanation is that anger hormones account for the apparently unreasonable moodiness（情绪化） of teens．Though hormones do play a role in human feelings，the real task of adolescence，and the real cause of the unrest，is the uncertainty of teenagers about who they are，alongside their eagerness to establish a sense of identity．
This involves self-questioning，self-discovery and self-development across a range of issues，including sex，faith，intellect and relationships．A sense of who we are is not a mere luxury； without it we feel worthless．A teen often looks upon his or her friends as models："I don't know who I am，but I know who he is，I'll be like him，"is the underlying thought．Parents also become such mirrors：teens want that mirror to reflect back to them the vividness and clarity they themselves do not feel．
Arguments with parents can often be understood in this context．While those common teenager-parent quarrels，which explode every few days，are often over small things such as homework，housework，and respect； a teenager's real focus is on a parent's recognition of his maturity and capability and human value．"No，you can't go out tonight，"implies that a parent you got your keys？"or"Do you have enough money for the bus？"are questions that can be easily accepted if asked by a concerned friend，but awaken a teen's own doubts if asked by a parent．Feeling the need to distinguish himself from the kid who can't remember to take his lunch，his keys or his money，he blames the parent for reminding him of the child-self still living within him．What my research shows is that quarreling with your teen doesn't necessarily mean you have a bad relationship．The quality of teenager-parent relationship has several measures．

4．Most students，when asked about their ideal graduation gift，would probably reply，"A car"，or"Money for a deposit on a house"．Cai Kaiyuan，21，made a different choice．As a graduation gift to himself，he decided to work as a volunteer teacher in a remote village in Tibet．
Cai，a senior majoring in electrical engineering at Hunan Railway Professional Technology College，originally planned to cycle from Sichuan to Tibet．During his journey，Cai's idea for a different graduation gift to himself began to take shape．"I did not know beforehand what the journey would mean to me．I just want to gain a unique experience and have pleasure in appreciating the view there，"he said．
It turned out cycling on a plateau （高原） was extremely challenging．And it has kept changing his outlook on life．Cai's fingers even became frostbitten while cycling up a 5008-meter-high mountain，where temperatures often dropped to 18below zero．At night，the ice covered the road and he fell off his bike three times．The lack of oxygen made him feel dizzy and weak．"At the most serious moment，I felt that my life wason the line，"said Cai．
However，he also gained something unexpected．At Ya'an，a city in Sichuan，he met a group of tourists who are also university students．A girl called Wu Ling told him that she planned to work as a teacher in a primary school in Tibet after her journey．He was impressed by the idea as she looked slender and weak．
It was not until he reached a family-run hotel in Shigatse that Cai's spirits began to rise．The hotel manager's two daughters enjoyed talking with him．The kids asked about his experiences on his trip，and showed him the beautiful local lakes．"They told me that they always liked to talk to guests，as they wanted to improve their Mandarin，"he said，"Their parents and many locals can only speak Tibetan．"
Cai was touched by the girls'story．Their situation is tough and the local people have little chance to learn Mandarin because the schools are short of teachers．"I want to do something to improve the situation for kids like them，"said Cai．His parents finally gave their agreement and his teachers also supported him．
