10.40 He’s by far the best player on the school team; there is no question about it.
(A) His being the best player on the school team is far from being true.
(B) It is certain that he is the best player on the school team.

(D)It is likely that he is the most qualified for the school team.
11. The development of information technology—computers and electronic communication devices—is
another factor currently influencing organizational structures. Automatic data-processing systems have been
widely 41 in a range of settings. Anyone who draws money out of a bank, or buys an airline ticket, depends
on a computer-based communication system. Since data can be processed 42 in any part of the world
linked to such a system, there is no need for physical proximity between those involved. However, a
fully-fledged “electronic office,” in which the bulk of the work is carried out by machines rather than humans,
is still 43 , and there are many problems in the way of its realization. 44 , there is a strong trend
towards the transplant of many office activities to electronic machinery. Word-processors, computer networks,
teleprinter links, and other electronic systems have already 45 the nature of much office work. In some
leading American banks, the trust department, where stock transfers are made, has been completely automated.
【題組】41 (A) introduced (B) intruded (C) invited (D) invaded
16. Gene therapy may be in its infancy, but great hopes for its potential to treat everything from cancer to
Alzheimer’s to heart disease are forcing it to grow up fast. After two decades of lab research, gene treatments are
increasingly making their way into human clinical trials. The bulk of research so far has focused on getting a gene to
its destination and coaxing it to turn on once inside a cell. On their own, genes can’t pass through cell membranes, and
much effort has been spent to trick cells into accepting foreign genes. The most efficient couriers are so-called viral
vectors: viruses whose genomes have been swapped out for therapeutic genes. Like Trojan horses, they slip genes into
target cells undetected. But as scientists are learning, there is no safe way to hijack a virus. The vectors sometimes trigger immune reactions. And once the genes are inside a cell, there is no way to be sure they will function as
intended. Case in point: a Paris gene therapy trial to treat SCIDs, or the “bubble boy disease,” restored immune
function in nine of 10 patients. But it was later revealed that two of them had developed leukemia.
