10Sample oneDirections：In the following text， some sentences have been removed. For Questions 41-45， choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices， which do not fit in any of the blanks. Mark your answers on ANSWER SHEET 1. （10 points）We are seeing a series of paradoxes at the turn of the millennium. On the one hand， globalization means that national frontiers are becoming increasingly meaningless， but on the other， we are being swept by a wave of parochialism， with countries clinging to the notion of sovereignty.41）But there are so many factors in the world that make this position increasingly meaningless. Governments no longer have complete control over their economic and monetary policies， and many multinationals now have greater profits than individual country's GDP.The end of the cold war has brought its own dangers and we need to find a new balance of power in the world. It has also spawned many conflicts. Governments must be prepared to surrender some authority to global and regional institutions or we risk world disorder. It is tragic that， just when we need a strong international organization， the United Nations is starved of funds and often sidelined by its own member states. What happened in East Timor was unforgivable because it was foreseeable. Angola has been another sad instance of international vacillation. 42）I do think world war is less likely for the present， although I worry about the proliferation of nuclear weapons at one end and lethal small arms at the other. 43）Another worry stems from the huge economic imbalances in a world where the richest 20 per cent have 86 per cent of global GDP， and the 20 poorest countries only one per cent.Humanitarian aid is no more than a palliative. 44）The international implications of， for example， the collapse of Africa are unthinkable. There must be a new concept of security based not just on military and defense matters but on economic and social concerns too. 45）The global pendulum has swung too far towards a total dependence on market forces， but finding some point of balance in the middle is extremely difficult. I am by nature optimistic， but in my gloomier moments I sometimes think the only solution will be an invasion from outer space-then at last everyone would unite！
A.As long as more than a million people continue to live in direct poverty we can never hope to achieve national or international stability.
B.We need an international body with teeth-morally and in action. Perhaps the UN should be given its own force.
C.Many members of the UN have only become nation states in the last few decades， so I can understand why they are so keen to hang on to their independence.
D.It is terrifying the way that power is increasingly disseminated to small， completely ruthless groups like terrorists， drug traffickers and local warlords. The great imponderable is that some nut could create a nuclear explosion. Or that some essentially local conflict could escalate out of control. You cannot isolate instability： it gets exported.

It is hard to attribute the success to the United Nations although no new world war broke out since its establishment. The United Nations is always helpless of preventing the regional wars.
G.The notion of sovereignty is more and more strong while the influence of the United Nations is weaker and weaker.
