石膏为什么不宜用于室外?

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 compared 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.

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)，Flixborough (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.

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(硝酸铵)，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 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.

The tourist trade is booming. With all this coming and going ， you'd expect greater understanding o develop between the nations of the world. Not a bit of it ! Superb systems of communication by air， sea and land make it possible for us to visit each other's countries at a moderate cost. What was once the 'grand tour' ， reserved for only the very rich ， is now within everybody's grasp ?

The package tour and chartered flights are not to be sneered at. Modern travelers enjoy a level of comfort which the lords and ladies on grand tours in the old days couldn't have dreamed of. But what's the sense of this mass exchange of populations if the nations of the world remain basically ignorant of each other?

Many tourist organizations are directly responsible for this state of affairs. They deliberately set out to protect their clients from too much contact with the local population. The modern tourist leads a cosseted， sheltered life. He lives at international hotels ， where he eats his international food and sips his international drink while he gazes at the natives from a distance. Conducted tours to places of interest are carefully censored. The tourist is allowed to see only what the organizers want him to see and no more. A strict schedule makes it impossible for the tourist to wander off on his own ; and anyway， language is always a barrier， so he is only too happy to be protected in this way. At its very worst ， this leads to a new and hideous kind of colonization.

The summer quarters of the inhabitants of the cite universitaire ： are temporarily reestablished on the island of Corfu. Blackpool is recreated at Torremolinos where the traveler goes not to eat paella， but fish and chips. The sad thing about this situation is that it leads to the persistence of national stereotypes. We don't see the people of other nations as they really are， but as we have been brought up to believe they are. You can test this for yourself. Take five nationalities ， say， French， German， English， American and Italian. Now in your mind， match them with these five adjectives ： musical， amorous， cold， pedantic， native. Far from providing us with any insight into the national characteristics of the peoples just mentioned ， these adjectives actually act as barriers. So when you set out on your travels， the only characteristics you notice are those which confirm your preconceptions. You come away with the highly unoriginal and inaccurate impression that ， say，'Anglo-Saxons are hypocrites' of that 'Latin peoples shout a lot'. You only have to make a few foreign friends to understand how absurd and harmful national stereotypes are. But how can you make foreign friends when the tourist trade does its best to prevent you ? Carried to an extreme， stereotypes can be positively dangerous. Wild generalizations stir up racial hatred and blind us to the basic fact 〞how trite it sounds ! 每 That all people are human. We are all similar to each other and at the same time all unique.

汉译英：生活就像一杯红酒， 热爱生活的人会从其中品出无穷无尽的美妙。将它握在手中仔细观察， 它的暗红色中有血的感觉， 那正是生命的痕迹。抿一口留在口中回味， 它的甘甜中有一丝苦涩， 如人生一般复杂迷离。喝一口下肚，余香沁人心脾，让人终身受益。红酒越陈越美味，生活越丰富越美好。当人生走向晚年，就如一瓶待开封的好酒，其色彩是沉静的，味道中充满慷慨与智慧。
