完形填空。     We have always been warned of the dangers of forest fires. They cause  1  to a forest.
They kill many plants and animals in an eco-system, which is a group of living things and their environment.
But have you ever heard of a forest fire that can be  2  for a forest? People start some of the fires
with a special reason to actually do good to the eco-system. In fact, fires are a natural part of any eco-system.
Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can  3   
some of these old trees. When the trees die, they provide something good for the earth. New trees can grow
strong and healthy in their place.
     Some trees even need fires to grow. These trees hold their seeds (种子) inside. Heat from a fire allows the
coat of the seeds to open up. Then the seeds fall to the ground and have the  4  to grow/ Scientist, who know
about nature"s needs, start some of these fires, called controlled burns. A fire is started and kept under control.
This way, the fire does not spread out of the area or  5  a after forest fires, they can go hungry  6  their food
has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food.
After some time, small plants begin to grow. Animals return soon after the plants return. 
     This  7  makes an eco-system. So the next time you hear about a forest fire, think about the good as well
as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier
than ever.

     Clean water is not only important for people to produce food, but necessary for our life. However, many
people in Asia and Africa don"t have enough clean water to use. The World Health Organization reports that
almost 4,000 children die each day of dirty water or lack (缺乏) of water.
     Farmers use 70-85% of the world fresh water to produce food. People usually don"t pay much attention to
how much water industry (工业) uses, but you may be surprised to know that industry uses 59% of the water
in developed countries.
     Home use takes up (占据) only 8% in the world. But as cities grow, more water will be used. The local
government has to try to make people use less water.
     In 60% of European cities, people are saving water by using less. They even keep waste wafer for other
use. In Australia, the government has encouraged people to collect rainwater and recycle water from showers
for a second use.
     The US Environmental Protection Agency has made a water saving program to encourage families and
businesses to check their water use and save more water. Scientists and the UN are looking for good water
management as the key to solving the problem. We can all work together to protect our fresh water in our
daily life.
(     )1. In developed countries, most water is used by industry.                               
(     )2. People in Asia have enough clean water to use.                                        
(     )3. To save water, Australians and Europeans both choose to recycle water for a second use.
(     )4. According to the passage, scientists have found good ways to deal with water problems.
(     )5. Home use of water will increase because of the growing of cities.

     Many countries put their garbage in the Pacific. Most of the garbage sinks. But plastic floats and 2______

kill them directly, but the fish (who are not smart!) think they are full. So, they stop 5______ (eat) and die of
hunger. Dolphins and whales will also eat plastic and die.
     Governments are starting to work together to clean up this area, but it will take many years. That"s why we
should always try 6______ (recycle) plastic... even our old toys.

                          Things You Can Do to Help the Environment
CARS
     Cars are getting bigger. Bigger cars burn more gas and increase problems with air pollution.
So try to walk, ride, or take buses or subways. And if you drive a car, keep it in a good state.
This can save gas and make less pollution.
Energy
     The biggest use of home energy is for heating and cooling. So turn up your air conditioned
and ,um down the heat, especially at night. Use energy-saving lights. And remember to turn
lights off.
PRODUCTS
     Each American throws away 10 kilograms of litter everyday. Try to make less waste. Ask
yourself before you buy something: Do I need it? Buy products that you can use over and over
again.
WATER
     Showers use a lot of water. In one week, a common American family uses as much water
as a person drinks in three years! Take shorter showers or buy a special small showerhead.
This can cut water use in half.
