Section Ⅲ Reading Comprehension (40 points)
Directions: There are 4 passages in this part, Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and blacken the corresponding letter on the ANSWER SHEET with a pencil.

It remains to be seen whether the world can maintain its linguistic and cultural diversity in the centuries ahead. Many powerful forces appear to work against it :population growth, which pushes migrant populations into the world’s last isolated locations; mass tourism; global telecommunications and mass media; and the spread of gigantic global corporations. All of these forces appear to signify a future in which the language of advertising, popular culture, and consumer products become similar. Already English and a few other major tongues have emerged as global languages of commerce and communication. For many of the world’s peoples, learning one of these languages is viewed as the key to education, economic opportunity, and a better way of life.

Whether most of these languages survive will probably depend on how strongly cultural groups wish to keep their identity alive through a native language. To
