PART I:
REACH THE TOP
DIRECTION: Read the following paragraph taken from the journal, Frontiers for Young Minds.
Identify the main idea and the supporting details.
We often forget how much humans depend on nature. Even city-dwellers living in
modern skyscrapers need air to breathe, water to drink, and food to eat,
all of which are provided by
nature. True, you can buy bottled water and ready-to-eat meals in supermarkets, but
they were not
produced there. Some fruits and vegetables, for example, only grow in
tropical countries and cross the
globe in refrigerated ship containers, to arrive just ripe to your local supermarket. All
drinking water
ultimately comes from a natural source, since we still do not have the
technology to manufacture large
amounts of water in the laboratory. The same applies to the air we breathe
, which is purified and
oxygenated by plants. So, when we speak about preserving nature, we are
really also talking about
preserving ourselves.
