     Happiness is U-shaped, for we are happier at the start and end of our lives but hit a slump (低潮) when

we are middle-aged, scientists from England and America say. They have studied the information on the

mental (心理的) health of two million people from 80 countries.

     In England, the probability of low spirits for men and women reaches the highest point at around 44 years

of age. In America, though, there is a big difference between men and women. Among women, unhappiness

reaches the highest point at around the age of 40, but among men, it is about 50.

     But the U-shape of happiness is unchanging around the world, and the mid-life sadness happens regardless

of marital status (婚姻状况), changes in jobs or pay. It happens to men and women, to single and married

people, to rich and poor, and to those with and without children.

     One possibility may be that people realize many of their dreams won't come true at middle age. The

researchers said another reason could be that seeing their middle- aged friends die one by one, people begin to

value their own remaining years and their Iove of the nature and long for peaceful and free life once more.

     But the good news is that if people make it to aged 70 and are still physically fit, they are on average (平均)

as happy as a 20-year-old person. For the average people in the modem world, the fall in mental health and

happiness doesn't come on suddenly in a single year. Only in their fifties do people get out of this low period.

1. Do people feel happy at the start and end of their lives?

阿尔迪、里德尔等德国超市折扣连锁店在全球食品涨价潮中逆市走俏。德国模式的折扣连锁店经营方式不同于普通超市、家庭店铺或法国特色的农民市场。它的店面一般仅有两三百平方米，过道狭窄，商品包装简单，80%以上的商品都是食品和饮料，其价格一般要比普通超市低30%到50%。分析人士认为，德国折扣连锁模式在食品涨价潮中逆市走俏的原因是多方面的。除了其“低价”优势外，折扣店品种少、规模大的采购模式使新开店成本很低。
以下哪项对上述分析人士的解释有所削弱( )

A．德国折扣连锁商店在法国零售业的市场份额已经从一年前的10.5%上升到11.2%，与此同时家乐福等大型超市的市场份额却在下降
B．低成本战略和低价战略是所有超市都在尽可能使用的经营战略，即力求在“价格优势”上压倒竞争对手
C．里德尔折扣连锁店在挪威被当地一家超市连锁店收购，挪威本土的这家连锁店，恰恰是德国折扣连锁模式的翻版
D．家乐福等大型超市多年来有自己的经营模式、经营理念并且形成了其特有的企业文化
