[问答题]Directions:In this section, there is one passage followed by a summary. Read the passage carefully and complete the summary below by choosing a maximum of three words from the passage to fill in the spaces 76 - 80. Remember to write the answers on the Answer Sheet.　　Questions 1- 5 are based on the following passage.　　Lack of culture, or rather an excess of the wrong sort of culture, is often considered to be synonymous with disadvantage. Most commonly associated with low cultural standards are low levels of reading, and some thirteen per cent of all twenty-three-year-olds feel they have trouble with reading and writing. One way of compensating such disadvantaged young people is thought to be to provide them with the culture they lack: in particular, high quality reading material.　　Whereas forty to fifty per cent of young people aged sixteen to twenty rarely read a book, the majority appear to read comics. In 1991 sales of Viz, a UK comic exceeded one million copies per issue, making it the fourth best-selling periodical in Britain. The reading of comics, however, is not restricted to young people: by 1992 it was estimated that two out of three men aged eighteen to fifty-three read Viz. The number of imitators of this comic has spawned, including Zit, Gas, BrainDamageand Swiz,indicates the extent of the influence it wields.　　The reading of comics was traditionally regarded by the educational establishment with considerable suspicion. Whereas the received arts were always assumed to exert an improving or civilizing influence, comics were thought to “rot children’s brains”, to lower educational standards and to threaten morality. They were, and are, assumed to be an inferior cultural form; their readers assumed to come from the lower social classes, to be low educational attainers and to be easily led astray.　　Over the past decade, perceptions of comics have shifted. Since the 1970s, the comic format has been commonly used to represent the interests of various disenfranchises groups—community groups, the unemployed, welfare recipients of—who became more conscious of a climate conditioned by other contemporary movements such as civil rights, consumerism, self-help and de-institutionalization. As cultural signifiers, comics have become the subject matter of academic courses in cultural and media studies. Indeed, young people’s cultural activities, grounded in the commercial rather than the subsidized sector, are beginning to merit the attention of the arts establishment.　　Summary:　　Low cultural standards，such as 　1　of reading，a difficulty experienced by many young adults, are often associated with disadvantage. While around half of sixteen to twenty-year-olds rarely read books，most will read comics. Although many comics in Britain are 　2　and have lots of readers，the educational establishment sill considers them to be an 　3　appealing only to the lower levels of society. However, attitudes are beginning to change as the format has been adopted to 　4　of disenfranchised groups. Certain comics have been included in the courses of 　5　studies. Young people’s cultural activities are beginning to attract the attention of the arts establishment.
