Text I
In almost all developing countries, the lack of
adequate supplies of cheap, convenient and reliable
fuel is a major problem. Rural communities depend"
largely on kerosene, wood and dung for their cooking
and lighting needs. But kerosene is now priced out of
reach of any people and wood, except in heavily
forested areas, is in short supply. The search for
firewood occupies a large part of the working day and
has resulted in widespread deforestation.
Dung is in constant supply wherever there are
farm animals and, when dried, it is convenient to store
and use. But burning dung destroys its value as
fertilizer, thus depriving the soil of a much needed
source of humus and nitrogen.
Rural areas of developing countries are also
plagued by a lack of adequate sanitation. Improper
waste disposal spreads disease, contaminates water
sources and provides breeding grounds for diseasecarrying
insects.
The problems of improving environmental
hygiene, conserving resources, and finding alternative
sources of fuel, may be unrelated. Their solutions,
however, are not, as many countries experimenting
with biogas technology are discovering. Biogas, a
mixture of methane and carbon dioxide, is produced
by the fermentation of organic matter. The process of
anaerobic fermentation is a natural one, occurring
whenever living matter decomposes. By keeping the
matter - and the process - in a digester of biogas plant,
the combustible gas can be trapped and used as fuel
for household lighting and cooking. The digested
slurry that remains can be used on the land as a soil
conditioner arid fertilizer.

Text II
Hurricanes generally occur in the North Atlantic
from may through November, with the peak of the
hurricane season in September; only rarely will they
occur from December through April in that part of the
ocean. The main reason for the occurrence of
hurricanes during this period is that the temperature on
the water's surface is at its warmest and the humidity
of the air is at its highest.
Of the tropical storms that occur each year in the
North Atlantic only about five, on the average, are
powerful enough to be called hurricanes, To be
classified as a hurricane, a tropical storm must have
winds reaching speeds of at least 117 kilometers per
hour, but the winds are often much stronger than that;
the winds of intense hurricanes can easily surpass 240
kilometers per hour,

6. The passage mainly discusses ....
A. the number of hurricanes in a year
B. the strength of hurricanes
C. the weather in the North Atlantic
D. hurricanes in a certain part of the world
E. hurricanes and disasters of the world

A. There are always hurricanes in the North-
Atlantic all year round.
B. Extremely warm weather and high humidity can
cause hurricanes.
C. Very strong winds are the result of hurricanes.
D. Hurricanes occur every month from May to
November.
E. Tropical countries have a lot of intense hurricanes.

Text IV
How much living space does a person need? What
happens when these space _10 are not adequately met?
Sociologists and psychologists are conducting
experiments on rats to try -11 the effects, of overcrowding
on humans. Recent studies have shown that
the behaviour of rats is greatly affected by space. If
rats have adequate living space, they eat well, sleep
well, and reproduce well. But if their living conditions
become too crowded their behaviour patterns and even
their health change _12... They cannot sleep and eat
well, and signs of fear and tension become 13 - The
more crowded they are the more they tend to bite each
other and even kill each other. -14 . for rats, population

for human society as well? Is adequate space not only
desirable but essential for human survival?
