Water supplies around the world are running dry.Scientists say the world is experiencing a shortage of fresh water.It will only worsen as the population grows fast and the climate changes.People living in the western part of the U.S.are experiencing this now.For several years,there hasn’t been much water.But the American West is not the only place thirsty for water.
Jerry Schubel,president and CEO of the Aquarium of the Pacific in Long
Beach,California,said,“More than half of the world’s population lives in water-stressed areas and according to the United Nations,that number will increase to two-thirds by 2025,fewer than 10 years from now.The amount of water on the earth has not changed for billions of years,but the ratio (比率) of fresh to salt water has.There are also other factors that are creating a fresh water shortage.In many parts of the world,shortage of fresh water is a looming (隐隐显现的) crisis that will become more serious by climate change and a growing p opulation.Most of the world’s population lives in countries that share bodies of water.Many of those countries don’t reach an agreement on how to share that water.”
Scientists think conservation is the most important step in solving the water crisis.Kevin Wattier,manager of the Long Beach water department,said desalinating —removing salt from sea water —is also an option.But that comes at a price.“It would cost at least twice or three times as much to desalinate sea water as it would cost to buy imported water.You will increase your global carbon footprint when you go to sea water desalination.”
Jerry Schubel thought the problem of global water shortage can be solved only if countries work together.“We could supply everyone on this planet with safe drinking water and enough water to grow their food.But it needs money,technology,political will and cooperation.And
learning how to share requires collaborative (合作的) decision made at intergovernmental (政府间的) levels.”

If you look outside,you probably will see some kinds of insects.If your first instinct is to kill it,take a moment to think about all of the benefits insects provide to the environment.
Entomologists,scientists who study insects,estimate that there are more than 800,000 species of insects found throughout the world.Only a few hundred of these insects are considered harmful.Mosquitoes,for example,are considered harmful.They bite humans and other animals,and their bites can cause skin pain and spread disease.Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year.
However,the number of helpful insect species far outweighs the number of harmful species.Some insects make up a vital part of the food chain.Many different birds,reptiles,fish and even plants eat insects.There are also about 500 insects that people in various parts of the world eat.These insects are considered delicious food and prized for their high protein,mineral,and vitamin content.Other insects produce valuable commercial products such as silk,wax,and honey.
Of all the insects,perhaps the most important are those that travel from flower to flower and pollinate(授粉) the plants they visit.Agriculture around the world would be very different without the bees,butterflies,moths,flies and wasps that pollinate many crops.In fact,nearly one-third of the food you eat depends on plants that are pollinated by insects!
While it is true that some species of insects harm or annoy us,you should not automatically reach for the bug spray when you come across an insect.You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings.
5.According to the passage,the most important type of insects are insects that .
A.are eaten by birds,reptiles and fish
B.travel around and pollinate plants
C.harm mosquitoes and stop the spread of disease
D.are eaten by people in many countries
6.According to the passage,insects are eaten in some parts of the world because .
A.they are nutritious
B.they are available to cook
C.they are easy to breed
D.they are free
7.According to the author,the sentence in the last paragraph “you should not automatically reach for the bug spray.” means .
A.you should not keep insects as pets
B.you should not breed insects for their benefits
C.you should not catch insects for pleasure
D.you should not kill insects without thinking
8.The main purpose of this passage is to .
A.explain why it is cruel to kill bugs
B.convince people that insects are nutritious
C.describe the beneficial contributions of insects
