There are three main groups of oils: animal, vegetable and mineral.
Great numbers of animal oil come from whales, those enormous crea- 【M1】______
tures of the sea which are the largest remaining animals in the world. To pro
tect the whale from the cold of the Arctic seas, nature has provided it with
a thick cover of fat called blubber. When the whale is killed, the blubber is 【M2】______
stripped off and boiled down, either board the ship or on shore. It produces 【M3】______
a great quantity of oil which can be made into food for human consumption.
A few other creatures yield oil, and none so much as the whale. The livers of 【M4】______
the cod and the halibut, two kinds of fish, yield nourishing oil. Both cod liv
er oil and halibut liver oil are given to sick children and other invalids who
need certain vitamins. These oils may be bought at any chemist. Vegetable 【M5】______
oil has been known from antiquity. No household can not get on without it, 【M6】______
for it is used in cooking. To the ordinary man, one kind of oil may be as im
portant as another. But when the politician or the engineer refers to oil, one 【M7】______
almost always means mineral oil, the oil that drives tanks, aeroplanes and
warships, motor-cars and diesel locomotives; the oil that is used to lubricate
all kinds of machineries. This is the oil that has changed the life of the com- 【M8】______
mon men. To it we owe the existence of the motor- car, which has replaced 【M9】______
the private horse-drawing carriage. 【M10】______ [br] 【M8】
