Our world has been for many year and throughout all those years we have used the sun for energy
needs. So why not use the energy to our homes or our cars?Many scientists have changed forms of
energy called "Green Energy". Green power is the solution to creating a cleaner,sustainable energy
system. Renewable (可重复的)energy—from the sun,wind ,plants and moving water—is a natural way
to meet our energy needs and protect the environment.
Solar (太阳的) energy is a very useful resource today. 80% of the energy we use comes from fossil
fuels (化石燃料) and about 1 % comes from solar energy. Fossil fuels are nonrenewable,that means
that they are used up faster than they could be replaced. Also fossil fuels are limited and cause pollution.
They are the primary cause for air pollution that causes acid rain (酸雨) and global warming. The good
thing about solar energy is that it is renewable because it is always replaced. Also solar energy does not
pollute the environment.
The energy problem is an important problem in the United States. Solar energy can help solve this
problem. But the cost is far too great. |
| 1. The underlined word "natural" means _______ in Chinese. |
A. 有用的

| 2. There is _______ of the energy we use coining from the sun. |
A. 80%
B. 1%
C. 81%
D. 79% |
| 3. _______ can make much pollution. |
A. Wind energy
B. Green energy
C. Solar energy
D. Fossil fuels |
| 4. What is NOT TRUE about the solar energy? |
A. Solar energy is a very useful energy.
B. Solar energy is renewable and replaced.
C. Solar energy can pollute the environment.
D. Solar energy can help solve energy problem in America. |
| 5. Which is the best title for the passage? |
A. Solar Energy
B. Fossil Fuels
C. Our World"s Energy
