A Teenage Inventor The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut．Olivia Hallisey，a junior at Greenwich High School，was awarded 50，000 in the Google Science Fair for her new method that detects Ebola，a virus that causes bleeding from different parts of the body and usually causes death．Olivia's method is to ask patients to put their saliva （唾液） onto a testing card．The card changes color if the person is catching Ebloa．Present Ebloa tests take up to 12 hours and cost ＄1，000．Olivia's method，however，can be done just in 30 minutes for about＄25．Besides，the sample （樣本） doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards．
Olivia was inspired to deal with this global problem after watching the news that more than 10，000 people died from Ebola in West Africa．She was particularly worried about the fact that，while the acts of involvement can improve survival rates，present detection methods are costly，time-consuming and require complex tools．Olivia got help from her science research teacher．She drew out directions from past research，and figured out detection systems that have proven to work with other diseases，including Lyme disease and yellow fever．
"What affects one country affects everyone，" Olivia told CNBC． "We have to work together to find answers to the huge challenges which cause harm to the global health．" The Connecticut's teen，who hopes to become a doctor one day，was named the Google Science Fair winner in the competition of 20 competitors from across the globe．The fair is open to young people between the ages of 13 and 18 in most countries．
Olivia hopes her success will inspire other girls interested in science and computers． "I would just encourage girls to try it in the beginning，and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science，" she told CNBC， "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests．"

1．When I was a boy growing up in New Jersey in the 1960s，we had a milkman delivering milk to our doorstep．His name was Mr．Basille．He wore a white cap and drove a white truck．As a 5-year-old boy，I couldn't take my eyes off the coin changer fixed to his belt．He noticed this one day during a delivery and gave me a quarter out of his coin changer．
Of course，he delivered more than milk．There was cheese，eggs and so on．If we needed to change our order，my mother would pen a note-"Please add a bottle of buttermilk next delivery"-and place it in the box along with the empty bottles．And then，the buttermilk would magically（魔術(shù)般） appear．
All of this was about more than convenience．There existed a close relationship between families and their milkmen．Mr．Basille even had a key to our house，for those times when it was so cold outside that we put the box indoors，so that the milk wouldn't freeze．And I remember Mr．Basille from time to time taking a break at our kitchen table，having a cup of tea and telling stories about his delivery．
There is sadly no home milk delivery today．Big companies allowed the production of cheaper milk，thus making it difficult for milkmen to compete．Besides，milk is for sale everywhere，and it may just not have been practical to have a delivery service．
Recently，an old milk box in the countryside I saw brought back my childhood memories．I took it home and planted it on the back porch（門廊）．Every so often my son's friends will ask what it is．So I start telling stories of my boyhood，and of the milkman who brought us friendship along with his milk．
（1）Mr．Basille gave the boy a quarter out of his coin changer．
A．to show his magical power
B．to pay for the delivery
C．to satisfy his curiosity
D．to please his mother
（2）What can be inferred from the fact that the milkman had the key to the boy's house？
A．He wanted to have tea there．
B．He was a respectable person．
C．He was treated as a family member．
D．He was fully trusted by the family．
（3）Why does home milk delivery no longer exist？
A．Nobody wants to be a milkman now．
B．It has been driven out of the market．
C．Its service is getting poor．
D．It is forbidden by law．
（4）Why did the author bring back home an old milk box？
A．He missed the good old days．
B．He wanted to tell interesting stories．
C．He needed it for his milk bottles．
D．He planted flowers in it．發(fā)布：2025/1/1 16:0:1組卷：16引用：3難度：0.9 -
