European farm ministers have ended three weeks of negotiations with a deal which they claim represents genuine reform. of the common agricultural policy(CAP). Will it be enough to kickstart the Doha world trade negotiations？
On the face of it, the deal agreed in the early hours of Thursday June 26th looks promising. Most subsidies linked to specific farm products are, at last, to be broken—the idea is to replace these with a direct payment to farmers, unconnected to particular products. Support prices for several key products, including milk and butter, are to be cut—that should mean European prices eventually falling towards the world market level. Cutting the link between subsidy and production was the main objective of proposals put forward by Mr. Fischler, which had formed the starting point for the negotiations.
The CAP is hugely unpopular around the world. It subsidises European farmers to such an extent that they can undercut farmers from poor countries, who also face trade barriers that largely exclude them from the potentially lucrative European market. Farm trade is also a key feature of the Doha round of trade talks, launched under the auspices of the World Trade Organisation (WTO) in November 2001. Developing countries have lined up alongside a number of industrial countries to demand an end to the massive subsidies Europe pays its farmers. Several Doha deadlines have already been missed because of the EU's intransigence, and the survival of the talks will be at risk if no progress is made by September, when the world's trade ministers meet in Cancun, Mexico.
But now even the French seem to have gone along with the deal hammered out in Luxembourg. Up to a point, anyway. The package of measures gives the green light for the most eager reformers to move fast to implement the changes within their own countries. But there is an escape clause of sorts for the French and other reform-averse nations. They can delay implementation for up to two years. There is also a suggestion that the reforms might not apply where there is a chance that they would lead to a reduction in land under cultivation.
These let-outs are potentially damaging for Europe's negotiators in the Doha round. They could significantly reduce the cost savings that the reforms might otherwise generate and, in turn, keep European expenditure on farm support unacceptably high by world standards. More generally, the escape clauses could undermine the reforms by encouraging the suspicion that the new package will not deliver the changes that its supporters claim. Close analysis of what is inevitably a very complicated package might confirm the sceptics' fears.
The deal agreed on Thursday looks promising in that ______.
A．European farm ministers finally reached a consensus
B．the link between farm products and subsidies is removed
C．farmers would definitely accept the direct payment to them
D．European farm products will reach a lower price level than the world

Now custom has not been commonly regarded as a subject of any great importance. The inner workings of our own brains we feel to be uniquely worthy of investigation, but custom, we have a way of thinking, is behavior. at its most commonplace. As a matter of fact, it is the other way around. Traditional custom, taken the world over, is a mass of detailed behavior. more astonishing than what any one person can ever evolve in individual actions. Yet that is a rather trivial aspect of the matte. The fact of first-rate importance is the predominant role that custom plays in experience and in belief and the very great varieties it may manifest.
No man ever looks at the world with pristine(未受外界影响的) eyes. He sees it edited by a definite set of customs and institutions and ways of thinking. Even in his philosophical probings he cannot go behind these stereotypes(固定的模式); his very concepts of the true and the false will still have reference to his particular traditional customs. John Dewey has said in all seriousness that the part played by custom in shaping the behavior. of the individual as over against any way in which he can affect traditional custom, is as the proportion of the total vocabulary of his mother tongue over against those words of his own baby talk that are taken up into the language of his family. When one seriously studies social orders that have had the opportunity to develop independently, the figure(这种比喻) becomes no more than an exact and matter-of- fact observation. The life history of the individual is first and foremost an adjustment to the patterns and standards traditionally handed down in his community. From the moment of his birth the customs into which he is born shape his experience and behavior. By the time he can talk, he is the little creature of his culture, and by the time he is grown and able to take part in its activities, its habits are his habits, its beliefs his beliefs, its impossibilities his impossibilities.
The author thinks the reason why custom has been ignored in the academic world is that______.
A．custom reveals only the superficial nature of human behavior
B．the study of social orders can replace the study of custom
C．people are still not aware of the important role that custom plays in forming our world outlook
D．custom has little to do with our ways of thinking
