问题     High oil prices have not yet produced an economic shock among consuming countries, but further rises, especially sharp (1)_____, would undoubtedly hurt the world economy, and (2)_____ would inevitably harm producers, too. Beyond this obvious point, (3)_____, higher prices could even do harm to both oil firms and producers.
Big oil firms (4)_____ rolling in money today, but that disguises the fact that their longer-term prospects are (5)_____. Behind the reserves-accounting scandal at Royal Dutch/ Shell (6)_____ a problem bedeviling all of the majors: replacing their dwindling reserves. (7)_____ existing fields in Alaska and the North Sea are rapidly declining, OPEC countries and Russia are (8)_____ them out. (9)_____ they are to survive in the long term, the big oil firms must embrace other sources of energy (10)_____ oil.
    (11)_____ it is to believe, higher oil prices could be bad news for producing countries (12)_____. Political leaders in Russia, Venezuela and other oil-rich countries are bending laws to crack (13)_____ on foreign firms and to strengthen their grip on oil (14)_____ through state-run firms. This may be convenient for the political leaders themselves. Alas, it is (15)_____ to do much for their countrymen. For years corruption and inefficiency (16)_____ the typical results of government control of oil resources.
    Producing countries should (17)_____ embrace open markets. (18)_____ one thing, shutting out foreign investment will only hurt their own oil output by (19)_____ the sharpest managers and latest technologies. For another, economic liberalisation (including reform of bloated welfare states) would help OPEC countries (20)_____ their economies—as the NAFTA trade deal has done for oil-rich Mexico—and so prepare them for the day when the black gold starts running out.

选项 A、but
B、so
C、however
D、nevertheless
答案C
解析 本题的考点为表示转折关系的副词词义及用法辨析。前一句提到油价的上涨会不可避免地伤害世界经济和生产者；这一句提到"______，除了显而易见的这一点，更高的价格甚至会对石油公司和生产者造成损害"。由此可推知这里缺少一个表示转折关系的副词，所以however"然而，不管如何"符合文意。but"但是"一般位于句前，so"因此"语义不当，nevertheless"尽管如此；不过"。因此这三项均不符合题意。
