 Part Ⅳ Reading Comprehension (Reading in Depth) (25 minutes)
   
    Section A
   
    Directions：In this section，there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words on Answer Sheet 2.
   
    Questions 47 to 51 are based on the following passage.
   
    For most people, shopping is still a matter of wandering down the high street or loading a cart in a shopping mall. Soon, that will change. Electronic commerce is growing fast and will soon bring people more choices. There will, however, be a cost: protecting the consumer from fraud will be harder. Many governments therefore want to extend highstreet regulations to the electronic world. But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation.
   
    Consumers in rich countries have grown used to the idea that the government takes responsibility for everything from the stability of the banks to the safety of the drugs, or their rights to refund(退款) when goods are faulty. But governments cannot enforce national laws on businesses whose only presence in their country is on the screen. Other countries have regulators, but the rules of consumer protection differ, as does enforcement. Even where a clear right to compensation exists, the online catalogue customer in Tokyo, say, can hardly go to New York to extract a refund for a dud purchase.
   
    One answer is for governments to cooperate more: to recognize each other’s rules. But that requires years of work and volumes of detailed rules. And plenty of countries have rules too fanciful for sober states to accept. There is, however, an alternative. Let the electronic businesses do the “regulation” themselves. They do, after all, have a self-interest in doing so.
   
    In electronic commerce, a reputation for honest dealing will be a valuable competitive asset. Governments, too, may compete to be trusted. For instance, customers ordering medicines online may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead.
   
    Consumers will need to use their judgment. But precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than consumers of the normal sort---and the new technology will also make it easier for them to complain noisily when a company lets them down. In this way, at least, the advent of cyberspace may argue for fewer consumer protection laws, not more.
   
    注意：此部分试题请在答题卡2上作答。

    51. _____________are probably more cautious than consumers of the normal sort when buying things.
Passage Two
   
    Questions 26 to 30 are based on the following passage.
   
    The importance of symbols as a source of cultural diversity can be seen in the dress codes and hairstyles of different societies. In most situations, the symbolism of clothing and hairstyles communicates different messages ranging from political beliefs to identification with specific ethnic or religious groups. The tartan(格子呢) of a Scottish clan, the black leather jacket and long hair of a motorcycle gang member in the United States, and the veil of an Islamic woman in Saudi Arabia provide a symbolic vocabulary that creates cultural diversity.
   
    Many examples of clothing styles could be used to illustrate how symbols are used to produce cultural diversity. Consider, for instance, changing dress codes in the United States. During the 1960s, many young people wore jeans, sandals, and beads to symbolize their rebellion against what they conceived as the conformist inclinations of American society. By the 1980s, many of the same people were wearing “power suits” as they sought to advance up the corporate ladder.
   
    An example of how hairstyles can create meaningful symbolic codes can be seen in a group known as the Rastafarians(sometimes known as Rastas or Rastaman) of Jamaica. The majority of the people of Jamaica are of African descent. During the eighteenth and nineteenth centuries, they were brought to Jamaica by European slave traders to work on plantations. The Rastafarians are a specific religious group within Jamaica who believe that Haile Selassie(1892-1975), the former emperor of Ethiopia, whose original name was Ras Tafari, was the black Messiah who appeared in the flesh for the redemption of all blacks exiled in the world of white oppression. Rastafarian religion fuses Old Testament teachings, Christian mysticism, and Afro-Jamaican religious beliefs. The Rastafarian movement originated as a consequence of harsh economic, political, and living conditions in the slums of Jamaica.
   
    In the 1950s, during the early phase of the Rastafarian movement, some male members began to grow their hair in “locks” or “dreadlocks” to symbolize their religious and political commitments. This hairstyle became well known in Western society through reggae(强节奏黑人音乐) music and Rasta musicians such as the late Bob Marley. Rastafarians derive the symbolism of the dreadlock hairstyle of the Rastafarians from the Bible. They view the unshaven man as the natural man and invoke Samson as one of the most important figures in the Bible. Dreadlocks also reflect a dominant symbol within the Rastafarian movement, the lion, which is associated with Haile Selassie, one of whose titles was the “Conquering Lion of Judah(犹大).”To simulate the spirit of the lion, some Rastas do not cut their hair, sometimes growing their locks 20 inches or more.
   
    Thus, to a great extent, culture consists of a network of symbolic codes that enhance values, beliefs, worldviews, and ideologies within a society, Humans go to a great length to create symbols that provide meaning for individuals and groups. These symbolic meanings are a powerful source of cultural diversity.
   
    52.What is the main idea of this selection?
   
    A．Hairstyles and dress codes identify political beliefs in diverse societies.
   
    B．The Rastafarian movement symbolized a religious and political commitment.
   
    C．Symbols provide meaning and a satisfaction of biological needs in society.
   
    D．Hairstyles and dress codes can be important symbols of cultural diversity in different societies.
   
    53.The author uses the examples of the Scottish tartan, the motorcycle jacket, and the Islamic veil to show             .
   
    A．the political power of dress codes in different societies
   
    B．the diversity of clothing styles throughout the world
   
    C．dress codes that symbolize different ethnic and religious groups
   
    D．the resistance to change of culturally different groups
