Bài 10: Đọc đoạn văn dưới đây và trả lời câu hỏi
East Somalia's prolonged the shortage of rain, which has already caused food supply to failand brought
unemployment in farming areas, could also affect the production of electricity, and thus reduce the output from
the nation's mines. The mining industry, and especially copper mining, uses a huge amount of electricity and
is almost completely dependent on the government Electricity Supply Commission. But the Commission
has recently asked the mines what would happen if electricity supplies were reduced by ten, twenty or thirty
percent.
The Commission's power stations which reduce the electricity using coal as fuel, are mostly situated near
the large coalfields of Eastern Province. But this area has little water so the cooling towers at the power
stations have to be supplied with water from elsewhere. The problem now is that water levels
all rivers and
lakes have fallen dangerously low and, in some cases, are well below the intake pipes which feed into the
pipelines which supply the cooling towers.
In a separate attempt to solve the problem, engineers are spending some forty million dollars on building
a series of small dams across the Haro river. It is hoped that these dams will make the water level at the
Malawa Dam rise so that water can then be pumped through a new pipeline to the power stations.
This will take time and it is now the dry season. Very little rain falls before October or November,
and after a shortage which has lasted for four years and is believed to be the worst in two centuries, nobody can
say whether the rain will be sufficient.
The amount of electricity and water used by the mines has tended to increase in recent years. The mines
which produce about half the country's export earnings, need electricity in order to pump fresh air through their
workings and to drive machines which crush vast quantities of rock. Each mine also has to provide
accommodation for as many as three thousands workers.
1. How might East Somalia's lack of rain affect electricity supplies and mining?
A. Copper mines are having to use less electricity
B. Coal supplies are failing to reach power stations
C. Electricity supplies to mines may be cut by up to thirty percent.
D. Copper mines may be unable to pump water by October.
2. Where does Electricity Supply Commission produce most of its electricity?
A. Along the Haro River
B. Near the copper mines
C. At the Malawa Dam
D. In Eastern Province
3. The action that the engineers are taking
A. may not help if the rain is sufficient
B. will become effective towards the end of the
year
C. should get enough water to the mines
D. will use up a lot of electricity
4. The engineers aim to
A. change the direction of the Haro river
B. keep more water at the Malawa Dam
C. get more water into the Haro river
D. dig out artificial lakes near the dam
5. Why are the copper mines important to East Somlia?
A. They train many skilled mechanics.
