问题    Woody Allen, in earlier, funnier days, told a joke about two women in a resort in the Catskills complaining about the cuisine: " The food at this place is really terrible," says one. " Yeah, and such small portions, " replies her friend.【R6】______They are dangerous things, their production and transport often unpleasant, the less visible environmental consequences of their use worse still. And there is not enough of them. The current boom in "unconventional" gas seems likely to provide good news on both fronts.
  【R7】______Oil is found in relatively few places, and its energy density, pumpability and ease of use in internal-combustion engines make it particularly well suited as a transportation fuel. Coal is found in many more places and it cannot be pumped around, but can be crushed and burned and so produces baseload power. Gas, typically found and exploited in the same sort of places as oil, is easily moved around through plumbing but is not, usually, seen as a transportation fuel.
  【R8】______Other innovations, such as producing liquefied natural gas from offshore sources and shipping it to its destinations directly, and technologies that might allow exploitation of the natural gas that is frozen into some permafrosts, further increase the scope for new production. 【R9】______
   Coal, unlike oil, is hard to embargo; and an obvious consequence of the changes in gas production is that they make gas supply a less potent political tool.【R10】______But countries can benefit from unconventional reserves without actually having any. More producers and a larger capacity to ship the fuel in its liquefied form will make gas a more fungible commodity. That continuing trend will mean that very few countries will ever be locked into a single source.
   A. Now new drilling technologies pioneered in America are allowing gas to be extracted from more types of rock, and thus from much more widespread sources.
   B. In Europe, where Russia has used supply cut-offs to put pressure on neighbouring Ukraine, discoveries of shale gas in eastern Europe could diversify supply in a useful way.
   C. All told, this transition to more plentiful, diverse and widespread reserves in effect makes gas a bit more like coal, and a bit less like oil.
   D. Gas that’s now being unconventionally extracted isn’t lying there underground in big natural pools near the earth’s surface, and it’s not easy to collect.
   E. Thus the current thinking about fossil fuels.
   F. The three conventional forms of fossil carbon — oil, coal and gas — differ both in the way the earth stores them and the way its people use them.
