II. Read the passage carefully, then choose the correct answers.
The natural environment includes all natural resources that are necessary for life: the air, the oceans, 
the Sun and the land. Because they are vital for life, these resources must be protected from pollution 
and conserved. Ecologists study their importance and how to use them carefully.
According to ecologists, resources are divided into two groups: renewable and non-renewable. When 
a resource is used, it takes some time to replace it. If the resource can be replaced quickly and easily, it 
is called renewable. If it cannot be replaced quickly and easily, it is called non-renewable. For example, 
grass for animals is a renewable resource. When cows eat the grass, the resources is used. If the soil is 
fertilized and protected, more grass will grow. Coal, however, is non-renewable because it takes 
millions of years to make coal. All fossil fuels are nonrenewable resources.

 SOLAR ENERGY
Sunlight carries huge amounts of energy. You can feel the Sun's energy when sunlight warms your skin 
on a summer day. To capture the Sun's energy, scientists have developed solar cells, called photovoltaic 
cells. These cells convert sunlight into electricity.
When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the 
particles in the solar cell to move faster, and the movement of these particles creates electricity.
In some places, large panels of solar cells harvest sunshine to make electricity for homes and 
businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free 
energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest 
places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their 
energy costs.
Experts say that the huge installation of solar panels in sunny regions could generate enough electricity 
to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. 
New ways to capture this energy are being developed all the time to maximize efficiency.

A. sunlight B. photovoltaic cells C. solar panels D. electricity
