It may be， however， that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children bee deeply interested in mathematics， they will probably make a success of that study. these accidents could have been avoided or controlled if effective measure had been taken avoid any accidents we should not repair the facilities in chemical industry ， which is stored in large tanks substance， which can39。 ， which can39。 the passage we know that ammonium nitrate is a kind of ____. city happened at to passage， the chemical accident that caused by the fault of management always occur in big cities are very rare in the chemical industry is safer than traveling by air. to work on public transport is safer than working at the office. of the following statements is true？ 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 Which is saferstaying 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 65 times 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.南方學(xué)習(xí)網(wǎng) 英語六級閱讀專項(xiàng)：王長喜六級考試標(biāo)準(zhǔn)閱讀(3)第十一篇： The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this which 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 28 workers at Flixborough. The worst accident of all was Bhopal， where up to 3，000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives， just a month before the unfortunate event at Bhopal. 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 reaction os exploding storage tanks. Yet， by a miracle， the two largest tanks did not explode. Had these caught fire， then 3，000 strong rescue team and fire fighters would all have died. at the office is safer than staying at home. at home is safer than working in the chemical industry. accidents are usually important enough to be reported as news because ____. often cause loss of life arouse the interest of all the readers ____. City gas， which can easily catch firet be stored in a great quantityt be used in overcrowded areas the discussion among some experts we may coclude that ____. local authorities should not be concerned with the production of the chemical industry gas
