[不定项选择题] 年9月18日18时50分左右，A铁厂发生煤气中毒事故，造成4人死亡，1人轻度中毒，直接经济损失170余万元。
2009年9月18日10时5分，A铁厂高炉休风。H时，甲班开始检修，当班烧结工（又称炉前工）没有按规程要求关闭煤气阀门和打开煤气放散阀即进行了作业。16时，乙班班长李某安排2名烧结工在东烧结平台配合机修工焊接阀盖密封箱体漏水点和盖板。18时25分，高炉恢复送风。18时50分左右，在未经确认是否具备输送煤气条件和采取其他相关安全措施的情况下，开始向东烧结机输送煤气。而郭某等4人仍在东烧结机平台下密封阀盖箱体内检修作业。由于高炉煤气输送到东烧结机的管道阀门未关闭，放散阀也未打开，煤气通过管道进人烧结密封阀盖箱体内，正在检修作业的3人（包括郭某在内）中毒死亡，1人因临近箱体人口处轻微中毒得以生还。当发现煤气阀门未关闭，另有1名员工前往关闭煤气管道阀门时中毒身亡。

American Dreams
There is a common response to America among foreign writers:the US is a land of
extremes where the best of things are just as easily found as the worst.This is a cliché（陈
词滥调）.
In the land of black and white,people should not be too surprised to find some of the
biggest gaps between the rich and the poor in the world.But the American Dream offers a
way out to everyone.________(1)No class system or government stands in the way.
Sadly,this old argument is no longer true.Over the past few decades there has been a fundamental shift in the structure of the American economy.
The gap between the rich and the poor has widened and widened.________(2)
Over the past 25 years the median US family income has gone up 18 percent.For the
top 1 percent,however,it has gone up 200 percent.Twenty-five years ago the top fifth
of Americans had an average income 6.7 times that of the bottom fifth.________
(3)
Inequalities have grown worse in different regions.In California,incomes for lower
class families have fallen by 4 percent since 1969.________(4)This has led to an
economy hugely in favor of a small group of very rich Americans.The wealthiest 1 percent
of households now control a third of the national wealth.There are now 37 million
Americans living in poverty.At 12.7 percent of the population,it is the highest percentage
in the developed world.
Yet the tax burden on America's rich is falling,not growing.________(5)There
was an economic theory holding that the rich spending more would benefit everyone as a
whole.But clearly that theory has not worked in reality.
________（2）
A.Nobody is poor in the US.
B.The top 0. 01 percent of households has seen its tax bite fall by a full 25 percentage points since 1980.
C.For upper class families they have risen 41 percent.
D.Now it is9.8 times.
E.As it does so,the possibility to cross that gap gets smaller and smaller.
F.All one has to do is to work hard and climb the ladder towards the top.
