这么多的权威机构,却难以猜违油价的“真面目”,是因为油价受到政治、经济、利益群体干涉等众多因素的制约,也是因为油价预测本身就存在着较大的主观性。 It is difficult for so many authorities to speculate on the “true colors” of oil prices because the oil price is restricted by many factors such as politics, economy and interference by interest groups. It is also because there is a big subjectivity in oil price prediction itself.
