4.Left Handedness
What do Leonardo da Vinci,Marie Curie,and Albert Einstein have in common?They were all left-handed,along with other famous people including Barack Obama.In fact,an estimated 13percent of the world's population (25)may/canbe left-handed.
Most people are right-handed.This fact also seems to have held true (26)throughouthistory.In 1977,scientists studied works of art made at various times starting with cave drawings from 15,000B.C.and ending with paintings from the 1950s.Most of the people(27)shown/showed(show) in these works of art are right-handed.
Many researchers claim (28)to have found(find)relationships between left-handedness and various physical and mental characteristics.However(29)someof these connections are very weak,and others have not been proven.What makes a person become right-handed rather than left-handed?As yet,no one really knows for sure.(30)No matter whatreasons may be behind it,people's attitudes toward left-handedness have changed a lot over the years.There are even a number of shops(31)specializing(specialize) in selling products for left-handed people,such as left-handed scissors,can openers,guitars,and even a left-handed camera.In 1976,Left-Handers International,a group of left-handed people in Topeka,Kansas,in the United States,decided to start (32)anannual event in order to clear up misunderstandings about left-handedness.
11.A new study suggests that early exposure to germs(细菌) strengthens the immune(免疫的)system.That means letting children get a little dirty might be good for their health later in life.
The study involved laboratory mice.It found that adult mice raised in a germ-free environment were more likely to develop allergies.asthma and other autoimmune disorders. There are more than eighty disorders where cells that normally defend the body instead attack tissues and organs.
Richard Blumberg,who led the study,is a professor at'Harvard Medical School in Boston,Massachusetts.He says,in 1989,medical researchers who sought to explain these diseases,first discovered that the increasing use of antibacterial soaps and other products,especially early in life,could weaken immune systems.
Now,Dr.Blumberg and his team have what is the first biological evidence to link early exposure to germs to stronger adult immune systems.They say this exposure could prevent the development of some autoimmune diseases.
In the adult germ-free mice,they found that inflammation(发炎)in the lungs and colon was caused by so-called killer T cells.These normally fight infection.But they became overactive and targeted healthy tissue-an autoimmune condition seen in asthma and a disease called ulcerative colitis.
Dr,Blumberg says the mice raised in a normal environment did not have the same reaction.He says their immune systems had been"educated"by early exposure to germs.
Rates of autoimmune disorders are rising worldwide,but mostly in wealthier,industrialized countries.According to Dr.Blumberg,it might be high time that people were warned to be more careful with the early use of antibiotics(抗生素) and the prescription from their doctors.
Rob Dunn is a professor of ecology and evolutionary biology at North Carolina State University in Raleigh.He says the new study does not mean people should stop washing."Wash your hands,but don't do it with antibacterial soap.Let your kids play in a reasonable amount of dirt and get outside and get exposed to a diversity of things",says Rob Dunn.
