12.Besides containing attractive flowers,trees and other plants that beautify the community,ecofriendly rain gardens are healthy for the environment and the people living and working nearby.A rain garden is not very different from a traditional garden.It is just a far more ecofriendly garden.Usually it is built lower than the ground.Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak(浸入)slowly into the ground before it runs into streams or enters the public drinking water supply.
Thus,a rain garden keeps the water,allowing it to be used as needed by plants in the rain garden,rather than flowing immediately into nearby streams and going unused.The water will soak slowly into the ground within a day or two.This creates an advantage that the rain garden does not allow mosquitoes to breed.This is a simple,attractive,and ecofriendly"green"way to treat storm water.
What's more,planting a rain garden helps reduce pollution and improve the environment.Without using expensive machinery and chemicals,rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.
Native plants are recommended for rain gardens because they are more used to the local climate,soil,and water conditions.They may attract local wildlife such as native birds.Water your rain garden immediately after planting and once a week,unless you have had at least an inch of rain during the week.Once native plants establish the necessary root system,they will require little care.
Often,local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems.However,you don't need to be a professionally environmental engineer to create a rain garden.As long as you're ecoconscious homeowners,you can help the environment by building smaller rain gardens in your yards.

Currently,the world is facing an epidemic (流行病) due to what is considered to be among the most dangerous viruses that humanity has ever faced-the Ebola bleeding virus.Though there were announcements about experimental treatments that were reported to be successful in terms of treating the virus,people around the world continue to die from Ebola.
Ebola was first discovered in 1976in Africa,on the banks of the Ebola River,after which the virus has been named.Back then,there were two major outbreaks of the virus,and this is how people learned about it.There exist several strains of the Ebola virus,some of them are deadly to people,and some are not.
The main symptoms of Ebola can appear in a period between the second and the 21st days of infection,but usually it happens on the eighth through 10th day.Among the symptoms that appear in the first turn,one should mention fever and chills,strong headaches,pain in joints and muscles,and general weakness.These symptoms are not too different from those that people usually experience when catching a severe cold,or flu,so victims may even ignore these symptoms,or try to treat them as a common sickness.However,as the virus keeps progressing,a patient develops nausea(呕吐) with vomiting,diarrhea,chest and stomach pains,red eyes and rash over the body,severe weight loss,and bleeding from almost all bodily openings.
The virus is usually transmitted either through blood,or through waste.Infection through blood usually takes place if a person consumes infested meat,or even touches it (for example,butchering can also lead to infection).Also,there were cases when people got infected after stepping in waste of infected mammals,mostly bats.The other ways of getting infected is through skin by receiving bodily liquids via tiny openings.
Even though there is no specific cure for Ebola,doctors still try to treat it.In order to diagnose Ebola,doctors usually take tests on such diseases as cholera or malaria,because it is difficult to diagnose Ebola based only on symptoms.After the diagnosis has been made,doctors start treating the symptoms,which includes killing infected cells,electrolytes,blood pressure medication,blood transfusions,oxygen treatment,and so on.
Though Ebola is a highly dangerous disease,it is not likely that it will spread globally.It is most deadly in anti-sanitary(不卫生的) conditions,which many African countries have an extremely bad reputation for.As for first world countries,even though there is still no universal cure,they are at much lesser risk than African countries.Though the symptoms of Ebola are severe and getting infected is not difficult,with the correct handling of an outbreak,the virus should not be able to spread.
(71)Introduction | ●Ebola,a dangerous virus,was named after the Ebola River,on whose banks it was first discovered. ●Despite the (72)announced/reported success in the virus treatment,people across the world continue to die from the virus. |
Symptoms | ●In the first turn,the symptoms are (73)similar to those that people experience when they are (74)suffering from a severe cold or flu. ●If not (75)taken seriously,the virus will keep progressing,and things will change for the worse. |
Ways of getting infected | ●People (76)consuming infested meat or touching it can get infected. ●People who step in waste of infected mammals,mostly bats,are (77)likely to get infected. ●People who receive bodily liquids via tiny openings can also get infected. |
Treatment and (78)prevention | ●After making correct diagnosis,doctors start treating the symptoms in many ways,(79)including killing infected cells,blood pressure medication,oxygen therapy,and so on. ●Sanitary living conditions play a significant (80)part/role in preventing the outbreak of the Ebola virus. |
