[填空题]Our society structure affects all human relationships. Outside the home we have a system of power relationship: worker/employer, individual/state, etc., and most people feel particularly powerless if their specific situations are beyond their control. The resultant stresses need outlets.
There are many different outlets. Many of us are inclined at least sometimes to take out our frustration (挫折) on people nearest to us. The kind of destructive outlet that a woman uses may be physical-either against her husband or children-but more often, it is directed towards her children who cannot walk out. Commonly, women turn violent feelings inwards: twice as many women as men suffer from depression (抑郁症). Women are the most vulnerable (脆弱的) to depression. As far as men are concerned, they have been brought up to use their fists-and even encouraged to do so.

[单项选择]Passage 3

[单项选择]Passage 4
All of us communicate with one another non-verbally, as well as with words. Most of the time we’re not aware that we’re doing it. We gesture with eyebrows or a hand, meet someone else’s eyes and look away, shift positions in a chair. These actions we assume are random and incidental. But researchers have discovered in recent years that there is a sys- tem to them almost as consistent and comprehensible as language.
Every culture has its own body language, and children absorb its nuances along with spoken language. A Frenchman talks and moves in French.
