[单项选择]Manners nowadays in metropolitan cities like London are practically non-existent. It is nothing for a big, strong schoolboy to elbow an elderly woman aside in the dash for the last remaining seat on the tube or bus, much less stand up and offer his seat to her, as he ought. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always a Continental man or one from the older generation.
This question of giving up seats in public transport is much argued about by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy, and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it is not agreed, however, that young men should stand up for younger women, the fact remains that courtesy should be shown to the old, the sick and the burdened.
Conditions in travel are really very hard on e

C. "Lady First" should be universally practiced.

Saudi Arabia, the oil industry’s swing producer, has become its flip-flopper. In February, it persuaded OPEC to cut its total production quotas by lm barrels per day (bpd), to 23.5m, as a precaution against an oil-price crash this spring. That fear has since been replaced by its opposite. The price of West Texas crude hit $40 last week, its highest since the eve of the first Iraq war, prompting concerns that higher oil prices could sap the vigour of America’s recovery and compound the frailty of Europe’s. On Monday May 10th, Ali al-Naimi, Saudi Arabia’s energy minister, called on OPEC to raise quotas, by at least 1.5m bpd, at its next meeting on June 3rd.
Thus far, the high oil price has been largely a consequence of good things, such as a strengthening world economy, rather than a cause of bad things, such as faster inflation or slower growth. China’s burgeoning economy guzzled about 6m bpd in the first quarter of this
A. U.S. currency is exerting a positive influence over oil price
B. another oil-price shock is inevitable given its continuing rise
