×年×月×日14时，××石化公司炼油厂油品分厂半成品车间无铅汽油罐区操作工黄×在开启210号汽油罐出口阀做循环调合时，误开了211号汽油罐出口阀，造成了211号罐内汽油打入已经满罐但入口阀处于开启状态的210号罐中。15时40分，仪表工陈××从计算机显示屏上发现210号油罐油面不断上升，随后计算机开始“高位报警”，陈××当即让黄××到罐区去核实一下210号罐的油面高度，黄××却误认为是计算机不准确，没去核实也未采取其他措施。16时，在交班时违反规定，没有在油罐现场进行交接班，也未核实油罐流程。17时50分，210号罐浮顶被顶破，汽油大量外冒、气化、扩散、流淌后，19时左右油蒸气遇罐区公路上行驶的由吕××所驾驶的手扶拖拉机的排气管火星而发生爆炸燃烧，万吨油罐冒起冲天大火，罐顶、罐区、阀门、沟管、山林同时多火点烧成一片，燃烧面积达23437.5m²。经过17h的扑救，大火于次日上午10时20分被扑灭，加上扑救地面复燃火势和持续冷却，23个小时后结束战斗。现场2人死亡(其中1名是农民工手扶拖拉机驾驶员吕××)，直接经济损失39万元。
经过事后调查，收集到的导致本起事故的一些线索如下：
(1)211罐收满油后，理应关闭罐根阀封罐，但这个岗位不关闭油罐的罐根阀进行封罐已成惯例。
(2)操作人员工作责任心不强，严重违反操作纪律，对210罐的高液位报警无动于衷，既不报告也未认真查找原因。
(3)操作工交接班未到现场进行交接，未认真核对运行流程只是进行了口头交接。
(4)巡回检查挂牌制等岗位责任制未有效落实，缺乏有效的检查与监督。
(5)罐区阀组各阀门上没有标记，几个罐的阀组并列在一条线上。
(6)该油罐区属一级防火防爆区，拖拉机等机动车辆理应禁入，厂里对外单位需进入该区域的机动车实行颁发通行证惯例，但当时手扶拖拉机驾驶员吕××所持的通行证已过期。
(7)防火堤内的排水明沟出罐区没有按规定加装闸门或阀门。
请根据以上情景，回答下列问题。1～4题为单选题，5～8题为多选题。请将正确答案代码填写到题干括号内。

这起事故的直接经济损失是39万元，若财产损失价值30.9万元，人身伤亡后所支出的费用是5.6万元，那么善后处理费用是( )万元。

A．2.2

B．2.5

C．8.1

D．33.4

E．75.5

The Frugal Gourmet Cooks American

by Jeff Smith

Our real American foods have come from our soil and have been used by many groups— those who already lived here and those who have come here to live. The Native Americans already had developed an interesting cuisine using the abundant foods that were so prevalent.

The influence that the English had upon our national eating habits is easy to see. They were a tough lot, those English, and they ate in a tough manner. They wiped theft mouths on the tablecloth, if there happened to be one, and they ate until you would expect them to burst. European travelers to this country in those days were most often shocked by American eating habits, which included too much fat and too much salt and too much liquor. Not much has changed! And, the Revolutionists refused to use the fork since it marked them as Europeans. The fork was not absolutely common on the American dinner table until about the time of the Civil War, the 1860s. Those English were a tough lot.

Other immigrant groups added their own touches to the preparation of our New World food products. The groups that came still have a special sense of self-identity through their ancestral heritage, but they see themselves as Americans. This special self-identity through your ancestors who came from other lands was supposed to disappear in this country. The term melting pot was first used in reference to America in the late 1700s, so this belief that we would all become the same has been with us for a long time. Thank goodness it has never worked. The various immigrant groups continue to add flavor to the pot, all right, but you can pick out the individual flavors easily.

The largest ancestry group in America is the English. There are more people in America who claim to have come from English blood than there are in England. But is their food English Thanks be to God, it is not! It is American. The second largest group is the Germans, then the Irish, the Afro-Americans, the French, the Italians, the Scottish, and the Polish. The Mexican and American Indian groups are all smaller than any of the above, though they were the original cooks in this country.

Which of the following statements is true().

A. People from other cultures or nations start to lose their self-identity once they get settled down in America.

B. The "melting pot" is supposed to melt all the foods but in reality it doesn’t.

C. The special sense of self-identity of people from other countries can’t be main- mined once they become Americans.

D. The "melting pot" finds it capable of melting all the food traditions into the American tradition.
