Oil
(Excerpt l)
by G.C. Thornley
There are three main groups of oils:
animal, vegetable and mineral.
Great
quantities
of
animal
oil
come
from
whales,
those
enormous
creatures of the sea which are the
largest remaining animals in the world.
To
protect
the
whale
from
the
cold
of
the
Arctic
seas,
nature
has
provided it with a thick covering of
fat called blubber. When the whale is
killed, the blubber is stripped off and
boiled down, either on board ship
or on
shore. It produces a great quantity of oil which
can be made into
food for human
consumption. A few other creatures yield oil, but
none
so much as the whale. The livers
of the cod and the halibut, two kinds of
fish, yield nourishing oil. Both cod
liver 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's.

要有三种:动物油,植物油和矿物油。其中大量动物油取
自鲸鱼。
这些巨大的海生物是在世界上现存最大的动物。
为了抵御北

海的寒冷,
鲸鱼天生就长有一层厚厚的脂肪
—

当鲸鱼被杀害,
鲸脂就会被剥除并进行熬煮。

这些操作会在船上或岸上进行。
鲸脂可

产大量的油,
这些油被制成食品供人类消费。
其他一些生物也出
产油,但没有鲸鱼这么多。

生病的儿童和其他残疾人某些维生

Vegetable oil has been
known from antiquity. No household can get
on without it, for it is used in
cooking. Perfumes may be made from the
oils of certain flowers. Soaps are made
from vegetable and animal oils.
植物油从古代就
为人所知。因为它用于烹饪,家中不能没有它。
香水可能由某些花的油提炼而成。肥皂是
由植物和动物油加工制成
的。
To
the
ordinary
man,
one
kind
of
oil
may
be
as
important
as
another. But when the
politician or the engineer refers to oil, he
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 machinery. This
is the oil that has changed the life of
the
common
man.
When
it
is
refined
into
petro
it
is
used
to
drive
the
internal combustion
engine. To it we owe the existence of the motor-
car,
which has replaced the private
carriage drawn by the horse. To it we
owe
the possibility of flying. It has
changed the methods of warfare on land
and sea.
在一般人看来,无论什么油都同样重要。但是当政治家或工程师谈
及油时,
他几乎总是指矿物油。
矿物油,
可以驱
动坦克、
飞机、
军舰、
电机车和内燃机
车,可以用来润滑各种机械。正是矿物油,改变了普
