The advancement of human civilization is possible just because of enormous contribution made by scientists.They are one of the most influential people of today's world.Here is a list of the four great scientists we've ever seen who changed the world.
Louis Pastcur（1822-1895）
Pasteur contributed greatly towards the advancement of medical sciences，developing cures for rabies（狂犬病），anthrax and other infectious diseases.He also invented the process of pasteurization（加熱殺菌法）to make milk safer to drink.He probably saved more lives than any other person.
Otto Hahn（1879—-1968）
Hahn was a German chemist who discovered nuclear fission（裂變） in 1939.He was a pioneering scientist in the field of radio-chemistry，and discovered radioactive elements in 1921.He was awarded the Nobel Prize for Chemistry in 1944.
Nikola Tesla（1856-1943）
Tesla worked on electromagnetism and AC current.He obtained around 300 patents worldwide for his inventions from electricity to radio transmission，but many inventions developed by Tesla were not put into patent protection.He played a key role in the development of modern electricity.
James Clerk Maxwell（1831-1879）

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(mén)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 -
