标题: 大家来看下这道题。答案选个A，感觉不痛不痒啊！
GWD6-Q4:
In the past the country of Siduria has relied heavily on imported oil. Siduria recently implemented a program to convert heating systems from oil to natural gas. Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Sidurian reliance on foreign sources for fuel should decline soon.
Which of the following is an assumption on which the argument depends?
A.   In Siduria the rate of fuel consumption is rising no more quickly than the rate of fuel production.
B.   Domestic production of natural gas is rising faster than is domestic production of oil in Siduria.
C.   No fuel other than natural gas is expected to be used as a replacement for oil in Siduria.
D.   Buildings cannot be heated by solar energy rather than by oil or natural gas.
E.   All new homes that are being built will have natural-gas-burning heating systems.

既然OIL是重要依靠，那答案应该趋向于何种办法能减少油耗或者说改变能源使用。这A选得太牵强了，消耗速度小于增长？那还不是要用油么？还不是要进口么？

fuel consumption 不能等同于 oil consumption的吧

題目: oil demand↓ 又國內oil產量上升，所以 Sidurian reliance on foreign sources for fuel should decline soon

但是oil demand=每人需求*人口所以 if In Siduria the rate of fuel consumption is rising "more" quickly than the rate of fuel production. 則結論會錯，所以B是assumption.

希望有幫道你~

注意rate!!,这个和percent一样，A正确。一个上升，一个下降，但是我一个下降的很快，一个上升的很慢。不要太去预测答案，无招胜有招，太去想架桥，什么其他的，反而让你无从下手
