单选题What is your favourite colour? Do you like yellow, orange, or red? If you do, you must be an optimist(乐观主义者), a leader, an active person who enjoys life,people and excitement. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist(悲观主义者). At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tell us, among other facts, that we do not choose our favourite colour as we grow up—we are born with our preference. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly. Colours do influence our moods—there is no doubt about it. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides(自杀)than any other bridge in the area—until it was repainted green. The number of suicide attempts immediately fell down sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue. Light and bright colours make people not only happier but more active. It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

单选题Soon after his appointment as secretary-general of the United Nations in 1997, Kofi Annan lamented that he was being accused of failing to reform the world body in six weeks. "But what are you complaining about?" asked the Russian ambassador: "You've had more time than God." Ah, Mr. Annan quipped back, "but God had one big advantage. He worked alone without a General Assembly, a Security Council and [all] the committees." Recounting that anecdote to journalists in New York this week, Mr. Annan sought to explain why a draft declaration on UN reform and tackling world poverty, due to be endorsed by some 150 heads of state and government at a world summit in the city on September 14th- 16th, had turned into such a pale shadow of the proposals that he himself had put forward in March. "With 191 member states", he sighed, "it's not easy to get an agreement." Most countries put the blame on the United States, in the form of its abrasive new ambassador, John Bolton, for insisting at the end of August on hundreds of last minute amendments and a line-by-line renegotiation of a text most others had thought was almost settled. But a group of middle-income developing nations, including Pakistan, Cuba, Iran, Egypt, Syria and Venezuela, also came up with plenty of last-minute changes of their own. The risk of having no document at all, and thus nothing for the world's leaders to come to New York for, was averted only by marathon all-night and all-weekend talks. The 35-page final document is not wholly devoid of substance. It calls for the creation of a Peacebuilding Commission to supervise the reconstruction of countries after wars; the replacement of the discredited UN Commission on Human Rights by a supposedly tougher Human Rights Council; the recognition of a new "responsibility to protect" peoples from genocide and other atrocities when national authorities fail to take action, including, if necessary, by force; and an "early" reform of the Security Council. Although much pared down, all these proposals have at least survived. Others have not. Either they provod so contentious that they were omitted altogether, such as the sections on disarmament and non-proliferation and the International Criminal Court, or they were watered down to little more than empty platitudes. The important section on collective security and the use of force no longer even mentions the vexed issue of pre-emptive strikes; meanwhile the section on terrorism condemns it "in all its forms and manifestations, committed by whomever, wherever and for whatever purposes", but fails to provide the clear definition the Americans wanted. Both Mr. Annan and, more surprisingly, George Bush have nevertheless sought to put a good face on things, with Mr. Annan describing the summit document as "an important step forward" and Mr. Bush saying the UN had taken "the first steps" towards reform. Mr. Annan and Mr. Bolton are determined to go a lot further. It is now up to the General Assembly to flesh out the document's skeleton proposals and propose new ones. But its chances of success appear slim.

单选题The family is a social institution. The importance of the family in an individual"s life usually depends on the size of the society. In small, primitive (原始的，早期的) societies, the family is the dominant social institution in an individual"s life. In larger, more complex societies, other social institutions are created to meet the needs of an individual. There are two basic family structures. The first structure is the extended family. The extended family includes all of an individual"s blood relatives, including spouse, children, parents, brothers and sisters, grandparents, cousins, and aunts and uncles. The nuclear family is limited to the basic family nucleus: father, mother, and children. The extended family structure tends to exist in agricultural societies. In such societies family ties serve as a strong source of cultural and societal interaction. The nuclear family structure tends to exist in industrialized societies. In industrial societies, other social institutions (such as religion, education, and government) act as the primary sources of cultural and societal interaction.

单选题 According to a new research, dreaming about something you've learned may actually be an indicator that your memory is working overtime to retain that information.
