  As the country's economy continues to steam ahead,once popular forms of entertainment,such as Karaoke(卡拉OK),card games and even boxing bars,appear to be losting their attractiveness.Stressed out white - collar wokers are camping out on rooftops,smashing(砸)up restaurants,pretending to be children and even visiting cemeteries in a effort to ease the pressure of modern life.

  Consider the members of Shanghai's Cat Rain club.By day,this group of young women work executive (决策管理的) jobs,but by night they climb buildings so they can spend the night on the roof."You feel relaxed when you're sitting on the roof,looking up to the sky and chatting with friends," said Gong Ying,25.

  The stress of work is not just limited to people in Shanghai.A recently opened restaurant in Beijing encourages customers(顾客) to smash plates --- as long as they are willing to pay to replace them.Some workers even wish to return to their childhoods.Recently,hundreds of people took part in a festival in which adults pretended to be children.It was an adultsonly event,and participants could read comics and eat sweets all day.

  Scenic places such as parks and rivers can also help people relax and put things in perspective.But a cemetery?

  Cemetery companies in Shanghai organized visits to local graveyards for stressed - out workers in March.The participants were taken to quiet spots in the cemetery where they could think about life and their futures."Pressure may bring us unhappiness,but it doesn't mean we can't find ways out,"says Chen Bin,a rooftop camping fan with still some other interests."Life should be imaginative."

  68.Peopel are going to those new activities mainly for ______.

   A.recreation   B.new ideas   C.physical refreshment   D.psychological relaxation

  69.The underlined phrase "put things in perspective"in the 4th paragraph possibly means______.
