6 The word “limited” in line 2 has the closest meaning to
A stopped B controlled C restricted D prohibited
B Solar energy has been used for generating
electricity since 1954 Solar panels are installed on
the roofs of houses to turn the energy of the sun
into the electricity that people can use for heating,
cooking, lighting and many other purposes In
order to get solar energy what we need are solar
panels and the sun One of the advantages of solar
energy is that solar panels are totally silent and
non-polluting However, solar energy also has
some disadvantages We can only generate solar
energy during daytime because the system
depends on sunlight
The main disadvantage of solar energy is
that solar panels are expensive Scientists are
doing their best to reduce the cost of solar panels
so that more and more people can use this
environmentally friendly source of energy in the
near future
1 Solar energy is unfriendly to the environment FALSE
2 People can get solar energy without the sun FALSE
3 Solar panels will be cheaper in a few years TRUE
4 There aren’t any disadvantages of solar energy FALSE
