15．Which is safer---staying at home，traveling to work on public transport，or working in the office？Surprisingly，each of these carries the same risk，which is very low．However，what about flying pared to working in the chemical industry？Unfortunately，the former is 65times riskier than the latter!In fact，the accident rate of workers in the chemical industry is less than that of almost any of human activity，and almost as safe as staying at home．
The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby．It is this that makes chemical accidents so newsworthy．Fortunately，they are extremely rare．The most famous ones happened at Texas City （1947），F(xiàn)lixborough （1974），Seveso （1976），Pemex （1984）and Bhopal （1984）．
Some of these are always in the minds of the people even though the loss of life was small．No one died at Seveso，and only 28workers at Flixborough．The worst accident of all was Bhopal，where up to 3，000were killed．The Texas City explosion of fertilizer killed 552．The Pemex fire at a storage（儲(chǔ)藏） plant for natural gas in the suburbs of Mexico City took 542lives，just a month before the unfortunate event at Bhopal．
Some experts have discussed these accidents and used each accident to illustrate a particular danger．Thus the Texas City explosion was caused by tons of ammonium nitrate（硝酸銨），which is safe unless stored in great quantity．The Flixborough fireball was the fault of management，which took risks to keep production going during essential repairs．The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep．When the poisonous gas drifted over the town，local leaders were incapable of taking effective action．The Pemex fire was made worse by an overloaded site in an overcrowded suburb．The fire set off a chain reactions exploding storage tanks．Yet，by a miracle，the two largest tanks did not explode．Had these caught fire，then 3，000strong rescue team and fire fighters would all have died．
25．Which of the following statements is true？D
A．Working at the office is safer than staying at home．
B．Traverlling to work on public transport is safer than working at the office．
C．Staying at home is safer than working in the chemical industry．
D．Working in the chemical industry is safer than traveling by air．
26．Chemical accidents are usually important enough to be reported as news becauseB．
A．they are very rare
B．they often cause loss of life
C．they always occur in big cities
D．they arouse the interest of all the readers
27．From the discussion among some experts we may conclude thatC．
A．to avoid any accidents we should not repair the facilities in chemical industry
B．the local authorities should not be concerned with the production of the chemical industry
C．a(chǎn)ll these accidents could have been avoided or controlled if effective measure had been taken
D．natural gas stored in very large tanks is always safe．
分析 先對(duì)比一些人類活動(dòng)的安全性，接著列舉發(fā)生在一些城市的化工事故，用數(shù)字說明那些事故造成的后果；最后文章解釋發(fā)生事故的原因．
解答 25．D．細(xì)節(jié)理解題：根據(jù)這句子"However，what about flying compared to working in the chemical industry？Unfortunately，the former is 65 times riskier than the latter!將飛行和在化學(xué)工業(yè)上班進(jìn)行比較，不幸運(yùn)的是，前者的冒險(xiǎn)機(jī)率是后者的65倍，結(jié)合選項(xiàng)，"可知D項(xiàng)正確．
26．B．細(xì)節(jié)理解題：從第二段的第一、第二句The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby．It is this that makes chemical accidents so newsworthy．可知，化學(xué)工廠由于出現(xiàn)問題而引起死亡；故選B．
27．C．推理判斷題：A 根據(jù)常理，若不對(duì)設(shè)備進(jìn)行維護(hù)，會(huì)增加發(fā)生事故的可能．所以不能避免，故排除；B 官方是應(yīng)該關(guān)系化工廠的生產(chǎn)活動(dòng)的．D 文章分明已列出氣體爆炸引起的事故，說明那不是總是安全的．所以C 正確．
點(diǎn)評(píng) 本文是一個(gè)新聞報(bào)道類閱讀理解，題目涉及多道細(xì)節(jié)理解題，做題時(shí)結(jié)合原文和題目有針對(duì)性的找出相關(guān)語句進(jìn)行仔細(xì)分析，結(jié)合選項(xiàng)選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測(cè)，一定要做到有理有據(jù)．
