材料一 近来，伊朗核问题争端日渐升级。伊朗总统艾哈迈迪-内贾德2007年1月11日表示，他不会被西方国家的“大惊小怪”所吓倒。他在伊朗阿巴斯港视察时说：“不幸的是，一伙欺凌弱小者要剥夺其他国家合法的、天然的权利。伊朗民族不会被这些霸权和他们的叫嚣所吓倒。”

材料二 中国外交部发言人刘建超表示，中方一贯支持维护国际核不扩散体系，反对核武器扩散，不希望中东地区出现新的动荡，并坚持通过政治和外交努力，以谈判方式和平解决伊朗核问题。刘建超表示，我们希望决议得到认真执行，同时认为制裁不是目的，也不可能从根本上解决问题。中方呼吁有关各方继续进行全方位的外交努力，推动尽快恢复谈判，寻求长期、全面的解决办法。中方将继续发挥建设性作用。

Work looks a better cure for poverty than welfare Especially as fewer and fewer countries will be able to afford to pay potential workers to stay at home a Victorian idea is back in favour: many poor people are better off when they are pulled back into the labour market. The idea revived first in the United States. There, in its harshest form, the unemployed work in exchange for welfare. But countries with governments to the left of America’s, including Labour Australia and Socialist France, are now also exploring ways to link income support and employment policy.

Coming from different directions, the right and the left are gradually finding new common ground. For the right, it seems deplorable to encourage the poor to rely on the state for cash, because they get hooked on government help and accustomed to being poor. For the left, it seems deplorable to allow workers to drop out of the job market for long periods, because it makes it harder for them to find new jobs. For both, the answer is to get the poor to work.

Most industrial countries have a two-tier system of social protection: a social-security scheme, where workers and their bosses make regular contributions in exchange for payments to workers when they are unemployed, sick or retired; and a safety-net, to give some income to those poor people who have exhausted their social insurance or who have none The former is usually not means-tested but, for the unemployed, is of limited duration; the latter is almost always tied to income The public tends to approve of contributory benefits, which is what designers of such schemes intended.

Safety-net benefits carry no such sense of entitlement, and are less popular. Yet they have grown more rapidly in large part because the 1980-82 recession increased the number of people of working age who had exhausted their right to contributory benefits. And an increasing proportion of the poor are people for whom the contributory systems were never designed: the young and lone mothers. In consequence, payments which carry a clear entitlement have become less significant, compared with those which appear to depend purely on state charity.

The rise in the bill for the unpopular kind of social protection comes at a time when governments want to curb state spending. It comes, too, at a time when many countries have done almost everything they can think of to protect the poor. A decade ago many on the left argued that poverty was usually caused by circumstances outside the control of the poor—a lack of jobs, disability, old age, racial discrimination, broken marriages. One way or another, governments have tried to tackle most of these problems. Still the poor remain.

Existing social security systems are increasingly expensive to operate because（）

A. more people have lost their jobs

B. many countries have done all they call for the poor

C. poverty has increased uncontrollably

D. more people are in the safety-net category
