6Despite extensive regulation, the chemical by- products of industrial firms continue to
pollute the environment, whether by intentional release into the air and water or by accidental
escape from toxic dump sites. Too costly to prevent entirely, such pollution can be controlled
naturally. Scientists have found that bacteria, fungi, and similar primitive microbes with a taste
for chemicals are readily found in contaminated areas. These tiniest of creatures are capable of
adapting to a poisonous environment by developing the metabolism to convert toxics into food or
by producing enzymes which can break down the chemicals. The tricky part is to find a way to
make the microorganisms populous and hungry at the same time.
Bioremediation is appealing to industrial companies because it is both simple and cost
effective. It is cheaper than incinerating the chemicals, the only other way to eliminate them
completely, and does not produce the toxic ash that burning does. Although it works best on
organic compounds such as gasoline or pesticides, bioremediation will probably work on highly
resistant as scientists engineer more powerful bugs.
61. What is the best title for this passage?
A. A Natural Means of Pollution Control. B. Regulating Chemical By- Products.
C. Forms of Environmental Pollution. D. The Tiniest Creatures.

63. What is the most difficult aspect of bioremediation?
A. Getting bacteria to adapt to toxic environments.
B. Converting poisonous compounds into food.
C. Increasing the number and appetite of microorganisms.
D. Convincing industrial firms to use it.
64. In line 9 the word “incinerating” can best be replaced by which of the following?
A. Burying B. Transporting C. Manufacturing D. Burning
65. It can be inferred that highly resistant compounds ….
A. cannot yet be effectively treated by bioremediation.
B. will eventually make bioremediation obsolete.
C. can be engineered by scientists to prevent pollution.
D. are similar to organic compounds such as gasoline.

Human memory, fomedly believed to rather inefficient, is really more sophisticated than
that of a computer. Researchers approaching the problem from a variety of points of view have
all concluded that there is agreat deal more stored in our minds than has been generally
supposed. Dr Wilder, a Canadian neurosurgeon, proved that by stimulating their brains
electrically, he could elicit the total recall of specific events in the subjects’ lives. Even dreams
and other minor events supposedly forgotten for many years suddenly emerged in detail.
 Although the physical basis for memory is not yet understood, one theory is that the fantastic
capacity for storage in the brain is the result of an almost unlimited combination of
interconnections between brain cells, stimulated by patterns of activity. Repeated references to
the same informtion supports recall. Or, to say that another way, improved performance is the
result of strengthening the chemical bonds in the memory.
66. With what topic is the passage mainly concerned?
A. Wilder B. Neurosurgeon C. Human memory D. Chemical
reactions
