over charge in the information age. Mr. Li highlights this point.
Hopefully, we can solve this problem in the near future.

XII. Read the following passage carefully and choose the best word or phrase
to fill in each blank.
We are living in the age of a telecommunications revolution. In order
to keep from getting left behind, many developing countries are
making an intensive effort to strengthen their telecommunications
infrastructure. This will help them catch up with the developed
countries. It was, after all, advanced telecommunications that gave
some countries an economic advantage over others during the 20th
century. There is one place that developing nations are looking to
improve upon. That is enabling their citizens and businesses to get
access to the Web. They are installing advanced optical fibers. These
fibers, a millimeter in diameter, can bring the information
superhighway to their door. The initial investments that countries like
Vietnam are making may seem too great because they still lack basic
utilities, like electricity and water. However, government officials say
that these moves are strategic. They are also confident that their
1 ．C 2. D 3. A 4. B 5. B 6. C 7. D 8. B 9. C 10. D
Cloze
countries will reap the benefits. They will benefit from having more
reliable and up-to-date telecommunications equipment and gaining
more revenues. One Vietnamese leader said, “It is understandable
that people want to tackle their immediate problems first. Still, our
entire future is at stake. People don’t always understand the
breadth of the problem, though.” He continued, “There are problems
with using the antique communications equipment. And if we continue
to use such old equipment, the gap between us and the developed
world will continue to widen. Sacrifices have to be made now so that
our children will have a country with opportunities equal to those
they see in the developed world.” It will not be far when they can
cruise alongside Americans and Western Europeans on the
information superhighway.
