Which of the following would be the best title for this passage()
A．Childhood Socializers
B．Norms & Role Models
C．Sources of Information
D．Agents of Socialization
A.
The first and most important agents of socialization are the people who care for infants. In the earliest months, messages from nurturers constitute the child’s basic understanding of the world around it. This is the infant’s first introduction to the language that shapes perception and elicits emotion.
B.
Another powerful source of information and socialization is the friendship of peers. Peers are equals that one can deal with on the same level as oneself, whereas parents are superiors. The heavy emotional overlay of family relationships makes some kinds of learning difficult.
C.
Much formal socialization is placed in the hands of professionals. Teachers from kindergarten on are specifically designated agents of socialization. Ideally, a teacher is one who has both knowledge and the skills to present it. During the course of teaching their subjects, classroom instructors provide role models and attempt to convey the excitement of learning itself.
D.
In earlier times, parents, friends and teachers would comprise the list of primary childhood socializers. Children’s books, comics and magazines might also have been mentioned as sources of information on norms and role models. Today one must add three powerful indirect or non-personal socialization agents: radio, movies and television. Many people learn about politics, form a vision of well-being, and develop attitudes towards others from what they see on the screen and hear through the speakers.

International Trade
B.
Since the end of World War II, international trade has developed dramatically. All countries in the modern world join in worldwide trade, through which various sorts of merchandise and (51) materials arc exported in (52) for foreign currency, which means income wealth from (53) and job opportunity at home, and in the meantime, foreign goods are imported to provide consumers with (54) and welcome merchandise. Today, economic interdependence among countries is so (55) that no country can close its doors to the outside world, and the more prosperous the national economy, the more developed the foreign trade. Economic globalization is now a (56) in the world.
C.
But in the past when old and new colonialism ruled the world there was no free and fair trade at all. Powers, (57) the British empire, the United States, Russia, Japan, divided the world into their spheres of influence—their colonies or dependencies, where their businessmen (58) their merchandise at high prices and bought (59) raw materials and labor at low prices. (60) of wealth flowed to these powers which then grew prosperous, (61) the colonies were driven into destitution (贫困). The national economy of colonies was innately defective. Their industries could not survive the overwhelming (62) of imports from the powers. Their monotonous national economy (63) in production of one or two agricultural crops or (64) products or minerals, to be sold in international market, for example, orange and sugarcane in Cuba, banana and coffee in South-America, coal in Poland, all (65) to supply-demand relation in world market under control of the powers. Even their customs were governed by officials from the powers, whose exported goods thus could enter the colonies nearly duty-free. It was after the collapse of colonialist system all over the world that free and fair international trade, at least theoretically, could be possible.
