基尼系数,是衡量分配不平等程度的重要指标。国际上通常认为,基尼系数低于0.2表示收入绝对平均;0.3-0.4.表示相对合理;0.4-0.5表示收入差距较大;0.6以上表示收入差距悬殊。 下列选项中,有关基尼系数说法不正确的是( )。

A.基尼系数是测量收入平等的指标

B.基尼系数可在0和1之间取任何值,收入分配越是趋向平等,基尼系数也越小

C.我国城市基尼系数从1978年的0.15上升至2000年的0.32,这说明至2000年城市居民个人收入差距逐步拉大

D.我国农村地区基尼系数在20世纪90年代为0.338左右,处于国际水平的相对合理区域

教学设计一:在教学求平行四边形面积时,教师讲授如下:连接AC,因为三角形ABC与三角形CDA的三边分别相等,所以,这两个三角形全等,三角形ABC的面积等于1/2底乘高,所以,平行四边形ABCD的面积等于底乘高,命题得到证明。然后,教师列举很多不同大小的平行四边形,要求学生求出它们的面积,结果每个问题都正确解决了。下课前,教师又布置了十几个类似的问题作为家庭作业。
教学设计二:教师引导学生分析问题,即如何把一个平行四边形转变成一个长方形,然后组织学生自主探究,并获得计算平行四边形面积的公式。
问题:两种教学设计中教师的教学方法有何不同两种教学方法对学生的学习将产生怎样的影响

Passage Four

Before the summer of 2000, the 54 year old John Haughom could accomplish just about any thing at work. "I could move mountains if I put my mind to it."he says of those days. But that summer Haughom found he couldn’t move them any more. On the phone with his wife one morn ing, Haughom broke down. A couple of days later Haughom checked himself in for a three-week stay at the Professional Renewal Center, an in-patient clinic 30 miles outside Kansas City that helps him deal with stress.
Haughom is far from alone. A host of new studies and plenty of anecdotal evidence show that stress in the workplace is skyrocketing. Whatever the cause, stress levels are at record highs. The statistics are startling. According to a new study by the federal government’s Nation al Institute for Occupational Safety and Health, more than half the working people in the U.S. view job stress as a major problem in their lives. This year the European Community officially dubbed stress the second-biggest occupational-health problem facing the continent.
Ten years ago experts warned that stress was out of control, in part because of a shaky economy. What’s notable about today’s wave of stressed-out workers is that it rises all the way to the top. Lack of control is generally considered one of the biggest job stressors, so it used to be thought that middle managers carried the brunt: sandwiched between the top and the bottom, they end up with little authority. Powerful chief executive officers (CEOs) were seen as the least threatened by stress. But in today’s tough economy, top executives don’t have as much control as they used to. "Stress is just part of the job, fortunately or unfortunately, stress’is part of our character building," Lebenthal says. "But I think I don’t need any more character building. What I need is a vacation."
But if you think that going on vacation is hard—and studies show that 85%of corporate executives don’t use all the time off they’re entitled to. Being able to handle stress is perhaps the most basic of job expectations. So among the corporate elite, succumbing to it is considered a shameful weakness. Stress has become the last affliction that people won’t dare admit to. Most senior executives who are undergoing treatment for stress—and even many who aren’t—refused to talk on the record about the topic."Nothing good can come out of having your name in a story like this," one CEO said through his therapist.

Why are middle managers regarded as the most threatened by stress

A.Because they don’t have as much control as they used to.

B.Because they are not able to handle stress.

C.Because they have little power over the situation in the company.

D.Because they need more character building.
